How to transfer an image from a computer to a TV. You can open access to folders in several ways
It’s easy to choose a suitable TV now, but if you want an excellent picture, then you’ll have to buy something like this http://electroberry.ru/televizory/katalog_televizorov/sony_kd-75x8505c/. If you are faced with the task of connecting a TV to a computer via an HDMI cable, then this procedure can be done like this:
- Disconnecting the TV and computer from the electrical network.
- Connecting an HDMI cable to the appropriate connectors.
- Turn on both devices.
Next, you need to make a setting that will allow you to display the image from personal computer to the screen television device. First of all, in Windows 10 you need to go to the display settings. To do this, call up the “Screen Resolution” item via the desktop. Next, click “Find” to search for the TV that was connected to the computer.
Note that there are several ways to display images from a computer screen running the Windows 10 operating system on a TV, when HDMI help cable. Once the TV is found, the user will be asked to select an image output mode. First of all, the operating system offers duplicate screens, that is, the same information will be displayed on the TV as on the computer. It is also possible to expand screens, that is, the TV display will be an extension of the computer display. IN in this case one workspace is created. Users are also asked to display the image on a TV. After pressing this function, the computer screen will go dark.
Connecting a computer to a TV via an HDMI cable to display an image is one of the simplest and most common methods. In addition, a suitable cable very often comes with a computer, laptop or TV. This way, you won't need to purchase it.
Using the above information, you can display the image from your computer to your TV in the shortest possible time.
It would seem like this simple procedure For modern computers and TVs as outputting video to a TV should not cause special problems when using an HDMI cable, network cable or Wi-Fi, but as always there are nuances. And the average person sometimes has to spend a lot of time to figure it out and display the video on the TV the way he wants. In this article we will look at how to configure the software and video output options on your TV.
If the size of the monitor and TV differs in resolution, video output via HDMI cable
IN Lately Manufacturers of modern TVs produce TVs exclusively with Full HD resolution (1920×1080 pixels). We will not consider 4K TVs due to them high cost, and at the time of writing this article they are clearly unaffordable, both for me and I think for you. Moreover, the purchase this TV in the absence of virtually any video in 4K format, makes the purchase of such a TV, on this moment, clearly unnecessary.
So, if the resolution of the computer and TV screens differs, then when outputting video to a TV via an HDMI cable, when setting up the TV, show the video in the original resolution ( best choice, so that there is no distortion of the original video vertically and horizontally), on the TV at the edges we will see black bars not occupied by video material. This is due to the fact that when you connect a TV to a PC via HDMI, you get an extension of the computer desktop onto a second monitor - the TV. At the same time, the expansion of the desktop onto the TV occurs with dimensions at the horizontal and vertical points of the computer monitor. But since the computer screen resolution is different from the TV resolution, we see black bars. For example, the resolution of a PC monitor is 1680x1050 pixels, and the resolution of a TV is 1920x1080. In this case, there will be black bars on the right and left of the TV that are not occupied by the image.
To solve this issue, let's turn to the driver of the computer's video card (in the example we will consider a video card driver made by AMD, for NVIDIA we do something similar). Go to the driver settings in the lower right corner of the PC monitor. In this case, the TV must be turned on in any mode, at least for watching broadcast TV programs, so that the PC can determine that there is another monitor connected via HDMI cable.
Or through the path Start, All Programs, AMD Catalist Control Center
In the window that appears, select the second monitor - Your TV
My Digital Flat Panels, Zoom Settings
Now you need to select on the TV required input video via HDMI to output images from a PC. In fact, this is the input where you connected the HDMI cable to the TV. When a picture of the PC desktop appears on the TV, we return to setting up the video card driver.
We launch the video movie, having first checked in the file properties that it is in Full format HD (1920×1080 pixels).
Note. I recommend viewing video files exclusively in Media Player Player Classic, included in the package of free codecs K-Lite_Codec_Pack and it doesn’t matter whether you have a full or mega pack codec installed - the player is always included in the package. This player is one of the few that plays all video files with any extension. Moreover, when watching, you will have the opportunity to customize both the sound and the video to suit your needs. this player allows you to change any settings while watching on the go.
When the video movie is running, drag the player window onto the second monitor - the TV, and expand the view to full screen. Now, using the “Scaling settings” slider of the video card driver, you need to adjust the horizontal size of the video to fit the entire screen. Moreover, if you do not adjust the video horizontally, then when watching a 3D video you will definitely have a double image, for obvious reasons, even if you are wearing the appropriate glasses. Usually you need to move the slider a little to the right, and sometimes all the way.
So, connection via HDMI cable With different resolutions We installed a monitor and a TV. Now is the time to consider connecting via network cable Ethernet or Wi-Fi network.
If the video, for example 3D, is not compressed correctly or has been changed to save space original size Images
Sometimes, when watching 3D video output via a PC, you can see the following picture - the image on the TV is flattened on the sides. As a result of this distortion, there can be no talk of any 3D image on the TV. For clarity, I will give an example of how it looks on a computer and, for obvious reasons, something similar can be seen on a TV without turning it on in 3D mode.
There are black bars on either side of the image. We will try to get rid of them.
And this can be solved quite simply. Let's use the same player Media Player Classic.
Let's launch a similar movie in the player and on the image, by pressing the right mouse button, call up the menu.
Select Video frame, Stretch to screen size.
As you can see, the image is stretched, and this is what we wanted.
Now all that remains is to drag the window media player Player Classic on the second screen - on the TV and switch the latter to 3D mode.
After these player settings, you will be able to view both 3D and regular video material with incorrect compression on the entire TV screen without additional manipulations with the TV settings.
Connecting a TV via an Ethernet or Wi-Fi network cable
This method of connecting a TV to a PC has a number of additional features compared to dragging the window with the player into a second window - onto the TV.
You can control video viewing from the TV remote control. Switch video files for viewing, rewind content, control sound volume. And to implement all this, you will only need to install on your computer a free Home Media Server (UPnP, DLNA, HTTP).
I will not talk in detail about setting up this home video servers so that global network There is plenty of information online. I’ll tell you in more detail about how to set up your TV and router.
Let's start with installing the Home Media Server itself (UPnP, DLNA, HTTP). Download from the link http://www.homemediaserver.ru/index.htm installation package program and install the media server on your PC.
After installing and launching the program, go to the settings and specify the folders with the video material that we want to view. Click the “Settings” button.
In the window that appears, click the add button
Specify the path to your media resources and click OK
And again OK
The program will offer to scan the added folder - agree
After scanning, start the server and minimize the program window
Let's move on to setting up the TV, in the example we'll look at connecting to an LG TV. And in order not to pull the wires, we organize the connection using wireless network Wi-Fi.
Go to the TV settings. Select Network, Connect to a Wi-Fi network
From the drop-down list, look for our router and click on it
A field for entering your wireless network password will appear.
Enter the required password using the keyboard on the TV screen and press Enter
If you did everything correctly, then in the line next to your router there will be a checkmark indicating that the connection has been established
Main advantage wireless connection is that the laptop is not tied to the location of the TV, and in some interiors this is crucial. However, it is desirable that both devices are located in the same room, since the iron reinforcement of the main wall can interfere with the passage of the signal, significantly reducing its quality.
You should also remember that connecting a laptop to a TV via Wi-Fi is not the best option for streaming data, for example, for displaying a computer game on the screen. Such actions are possible, but the signal is often unstable, may be interrupted, and this creates inconvenience. Ideally, this connection is best used for listening to music, viewing photos or videos.
In this article we will look at how to connect a laptop to a TV via Wi-Fi different ways depending on the available wireless signal transmission technology.
DLNA connection
This is the most common conventional type of wireless connection, available on almost all modern TVs. The only condition is that they have a built-in Wi-Fi module. Although sometimes you can do without it, as will be discussed below.
The main disadvantage of connecting using this technology is that it is not suitable for displaying a desktop image or a computer game from a laptop to a TV in real time, since it does not ensure synchronization of actions. You can only view photos, videos or listen to music that are pre-loaded into the TV’s memory.
Two options for connecting your TV via DLNA
Now let's move on to setting up the laptop.
Setting up a laptop in two steps
You can open access to folders in several ways:
Default general access open to the Pictures, Videos, Music and Documents folders on system disk(usually C). So you can just move necessary files to these folders.
To start watching files on TV should be pressed on the remote control HOME button and select the desired folder from the list of available ones on the network.
Also for convenience of working with shared folders and files in home network exist special programs, For example, Windows Media Center, included in the Windows operating system starting with Vista, or a similar program from a third party - Home Media Server. They greatly simplify the setup process, which usually comes down to just selecting a TV from a list of available ones. network devices and the necessary folders from the catalog.
Connection using WiDi technology
The Wireless Display (WiDi) or Miracast function is available on most modern Smart TVs and laptops with a built-in Intel 3rd generation video adapter or higher. Moreover, full support for this technology is guaranteed on proprietary Intel laptops with preinstalled operating system Windows 8.1 or Windows 10. Earlier editions (Windows 7/8) may require additional drivers, which can be found on the Intel website.
The convenience of WiDi technology is that all actions on the laptop are synchronized with the TV, which actually plays the role of a second display. Therefore, this connection is suitable for computer games, surfing the Internet and other streaming activities.
Establishing a wireless connection in this case is quite simple:
Connecting with an adapter
This feature is convenient for TVs that do not have a built-in Wi-Fi module, but have HDMI or USB ports. In this case, you need to purchase a special adapter that installs a virtual operating network on the TV and makes possible use almost all modern wireless technologies Smart TV, including Miracast.
As a rule, such adapters are “plug and play” devices, i.e. all necessary drivers are located on the device itself and are automatically activated when connected to a TV. Next, the configuration occurs in the ways described above.
Problems connecting a laptop to a TV wirelessly
| Description of the problem | Possible reason |
|---|---|
| The TV does not see the laptop via Wi-Fi |
|
| The laptop does not see the TV via Wi-Fi |
|
| There is a delay in transferring images from the laptop to the TV, and the video freezes. |

Sometimes the question arises connecting to a computer external monitor, TV or projector. The reasons for this action may be different: there is not enough
working space of one monitor, you want to watch a video or play on a new large-diagonal TV, or you need to make a presentation by connecting a projector to your computer.
To implement one of the above tasks, or something similar, first, you need to acquire the necessary equipment.
To connect a second monitor or TV to a computer, you need a video card with at least two outputs (HDMI, DVI, VGA, etc.). Majority modern video cards are equipped with two or three output connectors, so this should not be a problem
Attention! Make all connections to the video card with the computer turned off.
If everything is connected correctly, then immediately after turning on the computer the image will be displayed on both monitors, but after a few seconds, additional screen will go out. This is explained by the fact that the video driver controls the output of images, and until it loads, two monitors will work.
Now all that remains is to configure the display on the main and additional monitors. The fact is that the computer defines one monitor as the main one, and the other as an additional one. Tune Dual monitor modes in Windows 7 in the Screen Settings window. To do this you need to follow the link Screen resolution from context menu desktop 
In this window, you can designate the main monitor and secondary monitor, set the screen resolution, select the display orientation, and also select the display mode on two monitors.
In the settings it is possible to change their roles and places. There are four options for image output when connecting a second monitor (projector, TV):
- Display desktop on only 1
In this case, the image will only be displayed on the main monitor. - Display desktop only on 2
The option is similar to the previous one, only the image is displayed on an additional monitor. - Duplicate these screens
When this mode is active, the image is duplicated on both monitors. - Expand these screens
When activated this mode the taskbar will be displayed only on the main monitor, and the second monitor extends the boundaries of the first. By default, opened programs will be displayed on the main monitor. They can be easily dragged onto an additional screen by grabbing the window title with the mouse.
Depending on the location of the main and additional monitors, the space can expand in different sides. Mutual arrangement Dual monitors can be configured by simply dragging and dropping the monitor icons in the Display Settings window
Button Define allows you to determine which monitor you are currently on. When you click on it, a large number appears on each monitor, indicating the monitor number in the Windows settings.
It is very convenient to switch image output modes to monitors using the hotkey combination Win + P. When you press win + P, all 4 options for outputting images to monitors are available. Switching between monitors is carried out as follows: press Win + P simultaneously and, without releasing Win, press P until the desired mode is selected
Also, the Win + P hotkey combination may be needed in the following case. You used two monitors, and then removed one of them from the system, and the main one at that. At next switch on computer with one monitor, the screen may be black. This is where you need the Win + P combination to switch the mode.
If you have ATI video card and when outputting to a TV or projector, the image does not occupy the entire screen, and you see black bars around the edges, then you need to go to the video card driver settings Catalyst Control Center turn off the scaling mode by setting the slider to 0. The scaling mode is applied if the resolution additional monitor or the TV is larger than the main one.
Of course, you can simply play video on the monitor, but... As a rule, a TV has a number of advantages:
- Large diagonal. Monitors are rarely larger than 28”, while for a TV a diagonal of 40-60” is the norm;
- Better image quality. As a rule, a TV provides a better picture than a monitor - especially if we are talking about a laptop;
- Location. The monitor is usually located on the desktop, and the TV is positioned so that watching a movie is really comfortable.
Yes, you can use a DVD player, flash drive or external hard drive, but why endure additional inconvenience if you can directly connect your TV to your computer? In addition, this will allow you not only to watch movies, but also to simply use the TV as a monitor: surf the Internet, play and work - and all this without leaving the couch.
Methods for connecting a TV to a computer (hardware)
In order to connect your TV to your computer, you can use one of the methods below.
Connection via HDMI
HDMI is a very common connector that provides very high quality video and audio signal transmission. Today it is found in almost every computer and TV, which means you can simply connect both devices with an HDMI cable. Perhaps this is the simplest and most accessible method.
You can use standard cable HDMI-HDMI, if the ports on the TV and computer look the same - like this:
In rare cases, a TV or computer may have a mini-HDMI port - it is somewhat smaller in size. In this case, you will need a mini-HDMI to HDMI cable.
The HDMI cable transmits both image and sound; there is no need to use other cables.
Connection via DVI
DVI-I is another common interface that is similar in video signal quality HDMI interface. It is important to consider that audio signals are not always transmitted via DVI (for example, many ATI video cards do not have such a function).
With this connection, you will need to use additional cables to transmit the audio signal.
The DVI port looks like this:
Connection via VGA
VGA is standard port, which is present on almost all video cards. It looks like this:
Before using this connection, check the specifications of your TV and the list of resolutions it supports when connected via VGA. Many models only accept low-resolution signals via the VGA interface - in this case it would be better to use another method.
Just as in the case of DVI, audio transmission will have to be taken care of separately.
Connection via S-Video
The S-Video port can be found on most modern computers and televisions and is designed to transmit HD quality video signals. Sound is not transmitted through such a connection. The S-Video port looks like this:
Connection via SCART
The SCART port is often found on televisions and is designed to simultaneously transmit video and audio signals. The computer does not have such a port, so you need to use an S-Video-SCART or VGA-SCART cable:
You can also use an HDMI-SCART cable:
Connection via RCA (Tulip)
RCA is a three-connector interface that is equipped on almost all modern televisions and video cards. Doesn't provide much good quality video signal (in particular, color rendition suffers), but due to its prevalence, this method can be a good choice.
The port looks like this:
Connecting audio
If you use a video-only connection (such as VGA), you will need to take care of the audio connection separately. As a rule, minijack-minijack cables are used for this:
This solution is possible if the TV and computer have the appropriate connectors - regular ports for connecting headphones/speakers. If the audio input on the TV is RCA, you will need the appropriate cable:
Adapters
If your TV and computer do not have the same connectors, you can use different connection methods different interfaces. It can be:
DVI-HDMI:
VGA-S-Video:
VGA-DVI:
Cables for SCART were discussed above in the corresponding section.
Keep in mind that even using a converter you will not be able to get more high quality signal(for example, by connecting via VGA adapters with DVI, and DVI with HDMI, you will get the same quality as VGA).
Another important point: You shouldn’t skimp on cables - cheap connecting cords are poorly protected from interference, which leads to a drop in signal quality.
Settings and connection procedure
The standard connection order is as follows:
- Turn off the TV and computer;
- Disconnect the antenna, etc. from the TV;
- Connect all the necessary cables and adapters;
- Turn on the computer, wait for the system to boot;
- Turn on the TV.
If everything is in order, select the appropriate channel on the TV (you can find out more about it in the instructions) and you can go to Windows settings:
Settings for Windows XP
You connect your TV and computer to the router. It is important that DHCP is configured on the device - otherwise the network settings on the TV will have to be configured manually (how to do this should be indicated in the instruction manual).
Next, you need to install a media server on your computer - a program that will give the TV access to specific folders. This can be special software (for example, “Home Media Server”) or regular Windows Media Player. In the latter case, you need to enable the corresponding option: in the “Stream” drop-down menu located at the top left, select “Enable streaming multimedia", and in the settings window that opens, select your TV and click "OK".
In any case, you will need to choose which folders the TV will have access to - in WMP, for this you need to go to “Video Library Management” and add required folders. Next, you can select the “PC Browse” item on the TV (depending on the model, it may have a different name - see the instructions) and watch movies.
