How to connect the system unit to the TV. Connecting a TV to a computer - maximum possibilities


You may need to connect your TV to your computer to watch movies on the big screen. Also, many modern games on . In general, connecting a TV to a PC is just adding a larger monitor to the computer.

How can I connect a computer to a TV?

There are a lot of methods and options. This is due to the fact that TV connectors do not always correspond to PC connectors. And in general, compliance came not so long ago with the advent of the HDMI standard. Thus, now more or less modern PC and TV models are equipped with uniform ports, and there is no need to look for adapters. With models whose release date is very different, everything is much more interesting. In essence, a connection of this type comes down to bringing cables and adapters to one common denominator by selecting from those available. Let's look at what ports and connectors on a PC and TV might look like.

Signal ports on a computer

The most popular type of video output on a computer is D-Sub. But many people know it more as a VGA connector, which received this name for its use of the VGA video transmission interface of the same name. It was the most simple solution problems of how to connect a TV to a computer instead of a monitor. It is easy to recognize - it is a 15-pin connector, which is usually painted blue on the video card. The standard has been known since 1987 and has served faithfully all these years. However, it is gradually and inexorably being forced out of the market by “younger” and more convenient standards. And in 2015, Intel and AMD completely abandoned VGA support.

The next link in the history of connectors was DVI. Unlike VGA, the interface involves not only transmission analog signal, but also digital. It is still used today, but much less popular. It is worth noting that DVI has several types that can transmit either analog or digital, or a combination of both. Externally, the connector can contain up to 29 pins in the case of dual-channel mode for digital and analog video.

A little to the side is the S-Video connector. This type is more often found on other various equipment - video cameras or VCRs. May also be present on some video cards.

S-Video is also called component video, as it splits the video signal into components. That is, brightness and color are transmitted in different ways. For sound you will have to connect a separate cable. It is also worth noting that S-Video cannot transmit a signal high definition. It is gradually becoming obsolete and being replaced by more modern technologies.

Everyone has probably heard about HDMI. This is the most modern standard, which allows not only to transmit video up to 10K, but also sound. Latest version,2.1, boasts transfer speeds of up to 48 Gbps. HDMI differs from DVI in greater resolution, audio support, and compactness. It is actively being implemented in all modern TVs and video cards.

Connectors for receiving signals on a TV

It’s probably not worth talking about HDMI anymore, since a computer connector is no different from a TV connector. The only thing worth considering is the versions on different devices when connected. The SCART connector appeared in 1978. Still found on some models and devices. It is a fairly large 21-pin connector. It can transmit video signal components, as well as audio, both analog and digital.

A component connector includes several connectors. This is necessary to split video and audio signals into components. In this way, excellent quality is achieved by eliminating mixing interference. PC video cards are rarely equipped with such a set of outputs, so most often a special adapter is used.

The component connector divides both video and audio into components. By the way, in the photo there is a convenient HDMI adapter

The composite, or RCA, connector also has signal separation. However, here the video is not divided into components, but is transmitted over a single cable. Audio for the other two. RCA can be found on older televisions. Most often this connector is called “tulips”.

How to connect a computer to a TV via a cable in accordance with the available connectors

It is now worth considering in more detail how to connect different kinds connectors to similar or different ones, what can be used for this, and also how to connect speakers from a computer to the TV if the sound is not enough.

How to connect a TV to a computer via HDMI

This is the easiest way to connect a PC to a TV. Simply insert the HDMI cable connectors into the appropriate sockets on motherboard or computer video card, as well as on TV. The only difficulty that may arise is identifying the monitors on the PC. But for this in operating rooms Windows systems in the control panel there is a “Screen resolution” item, where you can find the connected monitors, set the transmitted resolution on them and indicate how it will be used - how additional monitor or a double of the main one.

How to connect a computer to a TV via tulips

Sometimes TVs only have primitive interfaces, so let's see how to connect a TV to a computer without HDMI, VGA and other newfangled connectors. Tulips have three different plugs: one for video and two for sound. This approach has not been used on PCs for a long time. Therefore, you will have to look for an adapter.

First, a little about the RCA standard itself. Each plug is responsible for its own type of signal and is painted in its own color. Yellow - video, white - left channel or mono audio, red - right audio channel. For greater convenience, the connectors on the devices are also colored. That is, it is quite difficult to insert the wrong plug into the wrong place.

Now you can connect tulips to HDMI or VGA without any problems. Many electronics stores have a large assortment of adapters. You can also look into the most famous Chinese online store.

How to connect an old TV to a computer

There is probably no universal recipe for how to connect an old analog TV to a computer. But we will now tell you the general algorithm. First, you need to carefully study the TV and determine what connectors it has. If there are several of them, you need to determine the most modern and functional one.

On an old TV, most likely, you will find something from composite, RCA or tulip, S-Video, as well as SCART. So the entire connection process will be just selecting the right adapter from standard to standard.

How to wirelessly connect a computer to a TV

Development wireless technologies TVs were also affected. This turned out to be so convenient that Wi-Fi is now being implemented in almost every model released over the past few years.

How to connect a computer to a TV via Wi-Fi

Before connecting via wireless networks, you need to make sure that the TV has Wi-Fi support. In fact, the connection process itself is connecting the TV to a common wireless home network, that is, to the router, then you need to install a media server on your computer that would share content with the TV. This is the easiest way to connect a TV to the Internet through a computer indirectly.

Using an example, it will look like this: go to the settings, on the remote control you can do this by clicking Settings, look for the “Network” section, then find the “ Network connection", select it and click "Configure connection" in the next window.

TV will ask you to select ours from the list of available networks and enter a password to access. Naturally, before connecting a computer to an LG TV, the network on the router must be configured. Then all that remains is to create a media server on your computer, or, more simply put, several shared folders, with which the TV can access PC content.

Connection via WiDi/Miracast technologies

Miracast technology and its analogue from Intel - WiDi allow you to transmit media content directly via Wi-Fi without various intermediaries. Moreover, this can be done both from computers and from mobile devices. Some Samsung TV models have their own implementation of technology called Screen Mirroring. Before connecting a Samsung TV to your TV, you need to make sure that it has this technology, since not all models support it. It is also worth remembering that wireless card The PC must be free.

How to connect sound from a computer to a TV

By default, HDMI is capable of transmitting audio, which is called “out of the box”. That is, any more or less modern TV and PC can be connected without additional tricks. With all other situations you will have to look alternative options. For example, a PC has VGA, and a TV has RCA. An adapter that would have, on the one hand, both VGA and sound, and on the other, all three RCA plugs, is a rarity. Therefore, you will need to find a VGA - RCA video adapter, and then a separate 3.5 Jack - RCA audio adapter. In general, now you can find any adapter, as well as more unified adapters with a set of connectors and plugs. The enterprising Chinese have especially advanced in this regard.

Special adapter for 3.5 audio to RCA

How to connect a TV to a laptop - nuances

It really couldn't be easier. Anyone, even old laptop at least contains VGA. The newer ones already have HDMI, which makes the whole process much easier. The only difficulty is to find the right adapter or adapter, which, if necessary, could transmit not only video, but also sound.

If you decide to connect your computer to your TV, you will almost certainly use this connection to watch any films or TV series, or to interesting game in a big company. TV will replace you large monitor, which is characterized by high price and inconvenience in everyday use. You will need special cable, the name of which depends on the capabilities of both the computer and the TV. Use the recommendations in this article to connect your PC to your TV and vice versa.

The first thing you need to do is decide on the cable to connect. Therefore, you need to carefully inspect the connectors on back cover computer system unit to find out which cables are suitable for it.

If you have a relatively new PC, you will most likely find the following connectors.

HDMI

HDMI is the most common type of connection for projectors and monitors today. Its connector looks like an oblong horizontal hole with many contacts inside. The advantage of this method is that it is very easy to find an HDMI cable: it is sold in any hardware or computer store, and is often included with a TV or other video equipment. If you find an HDMI connector in your computer, then half the work is already done.

DVI

This solution is considered somewhat outdated, but is very necessary if you have old TV, since you won’t find new connectors on it. The DVI connector is an oblong hole that consists of many small squares. It is difficult to confuse it with other exits, since it is quite large. In addition, you need to know that DVI transition is different:

  • DVI-I;
  • DVI-D;
  • DVI-A.

Each of them has a different structure, which is easy to distinguish by eye.


VGA

Also a relatively old connector that is still used by many projectors. To use it, you will have to connect speakers separately or accept that the sound will come from your computer speakers, which is also a good option.


S-Video

A round connector, often found on modern video cards. The quality of signal transmission will be higher than that of VGA.


On your TV you will find exactly the same connectors, but do not rush to despair if the connector on your computer and TV is different. There are many adapters that can be combined with each other. Main types of connection:

  • HDMI only connects to HDMI.
  • If your computer has a VGA output, you can connect it to the old VGA input on your TV.
  • DVI, however, also leads to VGA on the TV, but with best quality Images.
  • S-Video you can use with S-Video and AV. This option is less preferable as it produces a cloudy image.

You can look for adapters at your local store. For example, there is a transition from S-Video to SCART.


How to connect a PC to a TV - connect the cable to the devices

Unplug both the computer and the TV. Connect the cable. If you do not need a monitor from your computer, then it is also better to disconnect it from the system unit connector so as not to put unnecessary load on the computer.

Turn on the power, wait until the computer unloads. You will see that the entire image is transferred to the TV screen. However, you need to tweak the image a bit.


How to connect a PC to a TV - adjust the image on the computer

  • To ensure that the image is clear, you need to go to the screen settings settings. To do this, click right click mouse on the desktop and select “Personalization”.


  • Go to the “Screen” section.


  • Now select “Customize screen settings” in the left menu.


  • If you use both a monitor and a TV, and the number of screens is still displayed as 1, then click “Find”.
  • Once the second screen is found, you will see the “Multiple Screens” option. In it you need to select “Duplication”.


  • Set the screen resolution to the one that matches your TV.


There are several situations when it is necessary connect TV to computer. Fortunately, modern TVs fully support this feature. But first you need to clarify in what specific capacity you want to use this bundle. Well, for example, you can simply use a TV instead of a monitor via wifi or via cable. This method is the most common, and when a user enters a query on the topic of our article in a search engine, then, as a rule, he needs exactly this information.

How to connect a TV to a computer instead of a monitor?

For what? Quite often there are situations when it is advisable to have a larger monitor. For example, if you're playing a game, it's much nicer to watch everything on a big screen. Or if you want to watch a movie from the Internet directly on the big screen, but your zombie movie does not support an Internet connection.

In general, there is nothing complicated about connecting a TV to a computer, and even a child can cope with it. The main thing is to know what input connectors the TV that we want to use as a monitor has.

Analog or digital?

Without going into details that a simple TV consumer does not need to know, I will say that there are two types of transmission and reception of a radio broadcast signal - analog and digital. In analogue, the transmitter station sends a signal from electromagnetic waves, which cause vibrations in the antenna of the receiver, that is, the TV, and give an idea of ​​what picture and sound to show on the screen.

When digital at the transmitting station this signal encoded in digital code, which is received and recognized by the receiver. Thus, it turns out that the analog signal may arrive with distortions caused by other waves. Digital, if available, comes in absolutely pure form. Also, the analog signal can be received by any devices that are configured to operate on the same principle as the transmitting station. The digital one is reliably protected by a code that cannot be recognized if your device does not have the exact key to it.

In the end, what do we have in practice? Analog broadcasting is central television, which is caught by everyone, even the most ancient televisions. Digital - high-quality video, which is perceived only by devices adapted for this purpose.

So, when you want to find out how to connect a TV to a computer as a monitor, there are three ways - either through cables with analog connectors, or with digital ones, or from digital to analog through a special converter, since you won’t be able to connect a TV directly through a computer . All these difficulties occur due to the fact that your TV may not have the only connector that is on your computer. And although on modern models there are most of them and some option direct connection should definitely come up, sometimes it happens that you still have old monitor or a computer where something is missing.


You should also separate the connection of the video signal and audio - in most cases they occur separately.

How to connect a TV through a computer - video signal

  1. VGA (or D-Sub)

    Almost all monitors, televisions and computers have this output for connecting a TV through a computer, with the exception of only some inexpensive models laptops and netbooks. The standard, oldest analog method of connecting a monitor to a system unit.

  2. DVI

    A more advanced connection that works with both analog and digital monitors. It has its own subgroups:

    • DVI-D - works only with a digital connection
    • DVI-A - only with analog type
    • DVI-I - with both types

    Very often you can see how a DVI-A or DVI-I cable is connected to VGA through an adapter.

  3. S-Video

    Another popular connector. It is mainly present on non-computer equipment, so to connect a computer to a TV via this port you will need an adapter, or a converter if we're talking about, for example, about VGA.

  4. RCA

    The connector has long been outdated, but it is found on all versions of TVs and is the most convenient for DIY crimping at home. After all, it’s enough just to buy ordinary single-core coaxial cables and connect them with universally sold fork attachments. Consists of three wires - two audio and one video. It is also called “tulips” for the characteristic multi-colored connectors. In the absence of appropriate connectors, it is easy to use adapters or converters for s-video or vga.

  5. Scart

    A modern connector that allows you to achieve High Quality pictures and simultaneously transmit video and audio signals. All modern TVs are equipped with it, but may not be present in computers. In this case, it is also advisable to use an adapter, for example to VGA, RCA or S-Video with an additional audio cable.

  6. HDMI connection

    Another modern connector for connecting a TV to a computer with simultaneous transmission of high-quality audio and video. HDMI connectors are available modern computers and laptops, however, if you need to connect a monitor located far away, then a long cable will be very expensive and it would be more advisable to connect to it with other types of cables. You can also use an adapter to DVI-I. But organize an adapter with HDMI connections It won’t work on VGA, since the HDMI signal is digital, and VGA is analog. To do this, you need a special video converter that turns the digital signal into analog. A special feature of this connector is also the simultaneous transmission of audio and video signals.

  7. There are several more new, but still exotic connectors for connecting a computer to a TV and monitor. Such as UDI and DisplayPort. However, so far only a few companies have announced their support, so you may very rarely come across them.

    8. Despite the variety of adapters, to minimize losses in video image quality, it is still better to use the same connectors on both devices. Most likely, out of all this diversity, at least one method will coincide. If you still need an adapter from one standard to another, then do not rush to buy adapters.

    Consult the seller, telling him exactly from which connector you need to transcode the video and what exactly is needed for this. In some cases, just adapters will be enough, in others, special converters will be needed.

    How to connect computer audio to TV?

    This concerns video transmission. The sound connection from the computer to the TV is done using a cable, which has a standard MiniJack computer connector at one end, and two audio tulips (RCA) for stereo sound at the other end.

    Or by inserting an adapter for tulips into the audio output of the computer. In this case, again, you can easily make tulips yourself.

    On the computer, one end, which is the MiniJack (the usual plug of standard headphones), is inserted into the socket next to which the headphones are drawn. It is usually green in color.

    And the TV has two inputs for tulips, usually red and white (or black) colors.

    How can you connect a computer to a TV in practice?

    Now let's see directly in practice how the connection occurs using one of the cables. Let's take the simplest and most modern option - an HDMI cable, which will allow you to transmit both sound and picture to the TV at the same time. This connector is present on all models released in last years TVs and very often available on laptops and modern video cards in computers.

    We connect the cable between the computer and the TV cable through the appropriate connectors.

    Take the TV remote control and press the “Input” button, where we select as the source HDMI signal. Automatically, video and audio signals will be captured from your computer and an identical picture will appear on two screens.

    If your computer does not have HDMI, you can use one of the other types of cables, but you will have to connect audio and video separately. For example, for video, the most popular old VGA connector, which is present on many devices, or again use an adapter. And conduct the audio through a regular tulip. Or use the adapters mentioned above. In this case, already in the TV, as a source of audio and video, you will need to indicate the connectors that you used.

    There is a situation when the computer has only a digital DVI output, and the TV has HDMI, how to connect them in this case, since DVI is not designed for audio transmission? There is a way out, but it doesn’t always work - you can try using dvi-hdmi adapter connected to the computer. And already attach to it hdmi cable and stretch it to the zombie box. In this case, to transmit sound you need to use the built-in connector on the motherboard. sound card S/PDIF (if available, of course) transfer the audio signal via an internal cable to a similar connector on the video card so that it is also supplied to the DVI output. I repeat - this option may not work on all models of motherboards and video cards, so it is better to choose simpler methods.

    How to mirror the screen from a computer to a TV via wifi on Windows 7 or 10?

    Displaying a computer screen image on a TV can be realized not only by various types cables, but also via WiFi. There are several ways to do this.

  • On computers with Intel processors and Windows 10 already has a built-in feature called . With its help, it is easy to duplicate your computer screen onto your TV without third-party software. wireless signal.
  • Another way is to use . To do this, you need to install a separate one on the TV. And on the computer - the application with which it will work. This option is suitable for any operating system, both Windows all versions and for .
  • Finally, there is another device specifically designed for this type of connection -. We will also talk about this in another article.

These are the ways to connect a TV to a computer to broadcast images from it instead of a monitor.

Century digital technologies has already covered us all completely. Today, no sphere of human activity is conceivable without computers, and the entertainment industry is still thriving together with computer technologies. We remember how the first 21-inch monitors seemed simply huge to us, but today they won’t surprise anyone, and many still prefer a large-diagonal TV connected to the system as an alternative.

Today we will choose best cable to connect a computer and a TV, we will learn how to make the connection correctly, as well as a lot of interesting things on the topic.

Connecting the TV to your personal computer, laptop or compact tablet can be done different ways, the choice of which depends on the capabilities of the equipment.

  • In modern devices there are usually no problems, but with older devices there may be some technical problems.
  • We will build the connection rating in order of rationality and optimality, starting with the most common options and ending with the more rare ones.
  • In the second part of the article we will analyze alternative ways, which will allow you to make a connection when it is difficult to use classic cables.

So here are all the cables we can install:

  • HDMI– a cable that transmits picture and sound to digital quality. It is not only the highest priority in terms of image, but also the most convenient, since only one connector is required to connect.

  • VGA– this wire transmits an analog image. Modern video cards often they no longer have this connector, but a couple of years ago all devices were equipped with it. This video output can be found on most laptop models. The downside of the connection is that it cannot transmit sound, so a separate 3.5 mm mini-Jack cable is used with it. The picture quality remains at the same level.

  • DVI– this connector is considered completely computer, so it is not installed on TVs. However, you can use it by using adapters for the options indicated above. The signal produced by the cable is digital, sometimes analog.

Interesting to know! This connector cannot transmit sound, so when using an HDMI adapter, do not expect it to appear.

  • S-video– the presented cable has long been outdated and is not used even for transmitting a TV signal, but sometimes its installation is what is required, because old video cards had them, but the TV may not have other connectors.

Now let's find out in more detail how the listed connections are made.

How to connect a TV to a computer via HDMI

HDMI ( High Definition Multimedia Interface) is a single modern multimedia standard capable of transmitting images in high resolution, and the same high quality sound. It allows you to connect not only TV, but also speaker systems that need to transmit sound separately through channels.

Any modern TV, even the most inexpensive one, has at least one or two such inputs - this is what they look like in the photo.

The shape of the plug is made in such a way that it cannot be inserted incorrectly - there is a narrowing with bends in the lower part. However, not all connectors look exactly like this, because there is an option for compact devices (tablets, ultrabooks, smartphones).

In general, cables are usually divided into classes, among which there are the following options:

  • Type "A"- standard digital cable, capable of transmitting a signal in resolutions up to 1920*1080. This is what is used for connections, more often than other options. Its price is the lowest.
  • Type "B"- a more advanced cable that can transmit a picture in 4K resolution and a high-quality signal in 3D without loss of quality.

  • Types "C", "D"- these are the mentioned connectors for small devices. Connect them to standard cables through adapters, or the wire from the second edge has a plug of a standard shape and size.

The rest of the information on cables can be easily found on our website or third-party specialized resources. We are of little interest to it now, so let’s go straight to the connection.

So, all video outputs on the computer are located with reverse side system unit, video card or motherboard. Here's what it usually looks like in practice.

  • In the photos shown you saw output options on PCs and laptops. From external differences You will notice that the VGA on the laptop does not have threads for mounting screws - the cable is simply inserted.
  • The first thing you should do is take a close look at all the exits. If among them there is the HDMI we need, then we simply plug one end of the cable into it and install the block in place.
  • We look for a similar connector on the back or side panel of the TV, remember its number and make the connection. Manipulations with the cable end here, then we move on to setting up the equipment.

  • Depending on the TV brand, their menus will differ, but general scheme(with the possible exception of Phillips) will be very similar.
  • Press the output selection button on the remote control. It can be called and designated differently: In, TV In, Source, TV AV, a circle with an arrow pointing inward, etc. It is usually located in the top row, but this is not a fact.

Advice! If you haven't found it yourself the desired button, the instructions for the TV will help.

  • After pressing the button, you will see a drop-down list with available inputs on the screen. Select from them HDMI with the required number and click "OK".
  • The TV will begin to accept video and audio from the specified input, ignoring the rest.
  • Next, the computer is configured, but we will talk about this at the end of the article, in the corresponding chapter.

VGA connector is still popular

Technically VGA connection The connector is almost no different from the procedure already described, except that the shape of the connector is different and, as we have already said, a separate cable is required to transmit sound.

  • Look carefully at the photo. The VGA input is called PC IN (the name RGB may also be present) - this is important, as it will help us find required input to the sound.
  • Usually it is located nearby, but exceptions are possible. In this particular case, we see an input on the right labeled as PC/DVI Audio IN. You need to plug a 3.5 mm mini-Jack cable into it, like on headphones.
  • If the audio jack is not visible, it means that the TV does not support simultaneous broadcasting of audio from given input. You can get out of the situation by connecting an external sound system, the power of which will be enough for comfortable viewing of movies and other things.

Advice! At the back of the TV, in addition to the audio input, there may also be an output that will look exactly the same. They can be distinguished by the “poke” method, or by markings. The output can be labeled as AUDIO OUT, there can be headphones drawn there, or a circle with an arrow coming out of it.

S-video connector

This type of cable is also analog and is not intended for transmitting an audio signal. On sale you can find adapters from this connector to other television connectors, so you can connect any TV to a PC through this output.

On the TV, next to the cable, you can also see separate sockets for sound, but more often it is combined with the same tulips (AV). That is, they will have common sound inputs, and the image will be transmitted from the connected cable.

Connector options and combinations

It often happens that just the right connector may not be on your TV or computer. In this case, all kinds of adapters will help out.

Let's look at the most common of them:

  • The most common adapter is designed to move from a DVI connector to a VGA connector. It usually comes bundled with many video cards that do not have a separate VGA output. If such a device is not included in the kit, then do not rush to run to the store to get it. This connector may not support analog signal transmission.
  • To avoid confusion, you need to accurately determine the type of DVI connector, of which there are 4. Open the specification of your video card, which can be found on the Internet and look at the exact markings.

  • DVI-I Single link – this type supports simultaneous transmission of digital and analog signals, which means it is suitable for connecting the adapter we reviewed. The annotation “Single link” means that the digital signal is transmitted in single-channel mode.
  • DVI-I Dual link is almost the same connector, but has a double digital channel.

Interesting to know! Both options transmit the image in a resolution of 1920x1080.

  • DVI-D Single link - this output does not transmit an analog signal, and there is no point in buying an adapter for it - nothing will work. This standard is used, for example, on all nVidia video cards 10th series - we remind you that VGA is starting to be abandoned.
  • DVI-D Dual link – this connector due to its higher bandwidth can transmit an image with a resolution of 2560x1600 pixels. Just like the previous option, it is not used for transmitting an analog signal.
  • DVI-A is a rather rare option, which is designed to transmit only an analog signal. Wait, we wrote that there are 4 connectors, and this is the 5th in a row! That's right - this is how the plug in the adapter for connecting analog devices is designated.

In general, pay attention to the letter assigned to the name of the connector - I allows you to use an adapter, D does not.

  • The following adapter can be used if the TV does not have a VGA input, but has a component RCA input.

  • This option is similar in purpose to the previous one, but you can connect a “tulip” or s-video to it. You may ask why there is only one pin on the tulip. We will answer, because the other two transmit sound and are not needed here.
  • We have already mentioned the next adapter in the text. It is intended for digital data transmission, so the type of connector does not matter.

Advice! With this connection, the TV will not receive sound signal, and you won’t be able to connect it separately to the TV, since additional audio HDMI inputs does not have. For this reason, the sound will have to be supplied to separate playback devices.

  • You can also find adapters on sale from VGA to almost any analog inputs, be it RCA, tulips or even SCART.

  • We wrote that HDMI transmits only a digital signal, but this does not mean that the same VGA cannot be connected to it. To implement this diagram Not just adapters are used, but entire converters.

  • Converters can have separate power, or they can receive it from the computer. There is no big difference in functionality, so you can give preference to more compact devices.
  • Also HDMI can go to DVI if the circuit requires it, but to TVs this case clearly does not apply.

Connecting a TV wirelessly

If for some reason you can’t use a cable to connect your laptop and TV (the points are far apart from each other, you don’t want to leave the wires in sight), then you can try making a wireless connection.

Miracast

Implementing such a connection is only possible if your TV supports this technology.

  • Its essence is quite simple - a transmitting device through Wi-Fi module sends a signal encoded using a specific algorithm.
  • The receiving device sees it, decodes it and outputs it as a video signal.

Advice! Some TV models have support for this technology, but lack hardware, that is, they require purchase and installation separate equipment. Be sure to ask the seller about this feature if you plan to implement such a connection.

  • This means that even a smartphone can be connected to the TV in this way, provided that its power is sufficient, because the technology requires quite a lot of resources.
  • If you can't connect, make sure Miracast is enabled in your TV settings.
  • A TV that does not support this function can be connected via an external device with a separate power supply. It connects to the HDMI video input.

Smart TV

The development of digital electronics is moving toward the point where all gadgets are becoming multifunctional and capable of replacing other devices. The most striking example of such a transformation is smartphones, which from ordinary “dialers” have turned into portable ones. laptop computers, not much inferior in function full-fledged devices(the same PCs, cameras, voice recorders, etc.).

  • The development of television technology followed a similar path. Modern TV- This is not only a means for watching TV programs, but also partly a computer that can be connected to the Internet.
  • What does connecting to a computer have to do with it, you ask? It's simple - a PC configured in a certain way can distribute the Internet even via Wi-Fi.
  • As for the TV itself Smart function, then he is not full-fledged analogue computer. Basically we are talking about the use of certain resources - branded and publicly available, for example, YouTube.
  • Yes, individual models They have a built-in browser, but it is almost impossible to use it, due to the fact that the devices do not know how to clear the cache.

  • You can connect the TV in this way using a LAN wire or wirelessly. Not all models have a built-in signal receiver, so you may need to buy an adapter like the one in the photo above. The price for such a device is quite high.

Computer settings

So, we have completed the connection, all that remains is to configure the computer a little, because there may be no image, or it will be broadcast on two monitors at once.

  • Click on empty space desktop with the right mouse button. will appear in front of you context menu, in which you need to select the “Screen Resolution” item.
  • A window will open, as in the picture above, from where we can manage the broadcast parameters.
  • There are three main points here: screen, resolution, orientation.
  • By clicking on the triangle next to “Screen”, you will see a menu where you can select which monitor to use. this moment you need to display an image. Find your TV there, click on it, click “Apply” and “OK”. That's it, the image will appear on the TV screen.
  • It happens that the computer incorrectly sets the screen resolution - here you can set the value manually, according to the matrix resolution of your TV - usually it is either 1920x1080 or 1366x768. Modern TVs have a high resolution of 3840x2160.

Advice! To switch between monitors on laptops, there is usually a separate function button, read the instructions and you will be able to operate the system with greater convenience.

Let's summarize. Now you know how to connect correctly tv cable with a computer. We talked about many variations, so you will probably find a method that suits you and do it all yourself.

When the computer screen is not enough to satisfy all your needs, then a good old friend - the TV - comes to the rescue. Well, not very old, Rassvet is not suitable for these functions, but modern ones plasma panels They get along well with the computer. And then you can launch a game, favorite movie or music (although why would music big screen?) on wide plasma.

It seems that it is very simple, but in the process many encounter difficulties, and on the Internet they ask Google how to connect a TV to a computer. Fortunately, the search engine knows the answers to all questions. And this problem also has several solutions.

HDMI allows in the best possible way connect the PC to the TV. Through this cord you can transmit high-quality picture and even sound. The TV and the panel of the system unit must have a special connector with a height of 4.5 mm and a width of 14 mm. To make the connection, you need a wire with an HDMI plug on each end.

Some video card models are equipped with a mini-HDMI input, so you will also need a special adapter with standard version to mini. This adapter should come with the video card, so it's worth looking for it in old boxes. If it is not there, then purchasing will not be a problem; any computer store or point on the market sells such a product at a low price.

By the way, about the price. Materials, color and other features of the cord and adapter do not affect the quality of image transmission, but only the cost of the product. Consultants may convince you otherwise, but this is not true. Therefore, it is not worth buying a piece of cord for several hundred “evergreens”; cheap options for 5-15 dollars will also perform their function perfectly. Digital data will flow through the cable and will not be affected by any interference.

How to connect a TV:

DVI cables

First, you need to remember that DVI connectors, and therefore cables, are different.

Therefore, you should find out what specific type you need, and only then buy it. Each option has its own features and characteristics:

  • DVI-D This type conveys digital signals from the video card of the unit to the TV. Data is transmitted quickly and with high quality;
  • DVI-I. This cable is rightfully universal, because it provides both analog and digital transmission images and sound. Selecting this option will the best solution, although it costs a little more;
  • DVI-A. Most experts do not recommend buying this type of cable. Its peculiarity is that the data is processed from digital to analog, and only then appears on the screen and in the speakers of the TV. These processes greatly affect image quality.

The problem of connecting a TV to a computer can be solved using a VGA cable. The connector for this cable is standard and is present in all video cards for transmitting an analog signal. If there is a connector for it on the TV, then connecting will not be any problem. To do this you will actually need VGA cable and audio cable.

But before you start using this method, you need to check whether your TV supports a high resolution. The fact is that many TV models can only receive low-quality signals via a VGA cable. If everything is in order and high resolution is supported, then you can start connecting:

  • Disconnect equipment from the power supply;
  • Connect the corresponding inputs on the TV and computer with a VGA cable;
  • The audio output of the PC must be connected to the audio-in connector on the TV. This requires a special audio cable;
  • Power on the TV and PC;
  • Configure the computer and TV settings (similar to the settings from the HDMI connection);

RJ45 – network connector

To make such a connection, the TV must comply with two parameters:

  • It must have a media player (to put it simply, it must be able to play music, videos and images from a flash drive);
  • He must support DLNA technology and its block must contain an RJ45 network connector;

DLNA is a special technology that allows for the exchange of information between the TV and other devices in real time. Thanks to this system, it is possible to play files directly from hard drive without transferring them to other media. Find out if there is such a function in specific model TV can be found in the instructions for it or on the manufacturer’s website.

To connect your TV to your computer, you need:

  • Make a physical connection;
  • Download and install special program(it's free);

The first stage involves connecting directly or through a router. It is not recommended to use a router, because then you have to huge pressure, which will lead to loss of performance. In order to connect without a router, you need a “Crossover” cable type “ twisted pair" The crimp of the cord must be cross. You will also need to make changes to the IP settings.

The following configuration will work:

If the computer contains two network cards, then you only need to configure the one that connects to the TV.
You also need to download and install the application " Home media server" After this, you need to change certain settings (when the cable is already connected and the equipment is turned on):


To view files, you need the equipment to be turned on, the Home Media Service program to be running, and the source of media files to be set to Ethernet (Lan). This will open Explorer, which will allow you to view the required files using the remote control.
