Connecting a monitor to a laptop with a broken screen. Connecting a monitor to a laptop
First of all, look at the connectors on your laptop. On one side you will find a connector for connecting external monitor. The most common are VGA, DVI and HDMI. On modern devices You can also find DisplayPort.
Port VGA on a laptop. 
Connector HDMI.
After finding the connector on the laptop, we inspect the existing monitor for the presence video port– it is located at the back of the device. 
Ideally, the port on the laptop should be the same as on the monitor, but if there are no identical connectors, adapters (video converters) come to the rescue. Exists a large number of adapters from DVI to HDMI, from VGA to DVI, etc. There are also universal adapters with multiple interfaces.
How to connect and set up a monitor
It is better to make a connection when the device is turned off, since some laptops only check for a second display at startup.
To connect, take a cable with the appropriate connector.
VGA cable
HDMI cable
DVI cable and connector
A more exotic option - VGA cable–miniVGA. 
This cable can be used, for example, to connect to a TV.
We connect one end to the monitor and the other to the laptop. 
Immediately after connecting, you will see the same picture on both displays - it will be duplicated (clone mode). 
However, it is not always necessary to display the same image on both the laptop and the monitor. In addition, the resolution is often chosen incorrectly; the lowest resolution of the two displays used is taken as the basis. Therefore you will need configure.
On the desktop, right-click – “”. 
If the monitor is not immediately detected, then in the window that opens, click the “ Find». 
Then you need to determine which display is the main one, which screen will be to the right and which to the left. This can be done using the button " Define" in the same part of the window.
Please note that in the field " Multiple monitors"You can choose to duplicate the image, expand it to both screens, or display it only on one. 
The first option can be used, for example, when showing presentations. In this case, one of the screens is in front of you, and the second is in front of the audience (a projector is often used for such purposes).
The second is the most convenient, and therefore more often used. 
When you select this mode, you can change the resolution for each screen separately.
After making changes, click " OK" and let's get to work.
In this mode, you can move icons and files between two screens, which is very convenient when working with a lot of software at the same time. The size of the visible space doubles. You can watch a movie and chat at the same time in social networks. No need to constantly switch between applications. This will undoubtedly lead to increased productivity Your work.
The third option is used, for example, if the laptop screen is faulty and you decide to use another one for your tasks.
If you want to quickly switch between monitors, there is a hotkey combination Win+P. Pressing this combination opens a window for selecting the operating mode of multiple screens. This is what it looks like for Windows 7. 
For Windows 8 and 10, a pop-up window appears “ Projection» on the right with similar parameters. 
The setting can also be done using specialized utilities. For example, if you have integrated video from Intel, then right click On the desktop, open the graphics options and then, as shown in the picture. 
Algorithm connecting the projector similar.
We all know that sooner or later any technology becomes unusable. This is especially important to consider in currently- in times of technological progress. Now every home has computers, and some even have more than one. It would be very sad if his monitor broke. It’s especially sad if you urgently need to work with files on your computer. Repair in this case is unlikely to be suitable, because it will take a lot of time, and the result may not suit you, but what to do then, in this case?
In this article we will look at how to use a laptop as a monitor for a computer. Yes, this is possible. Moreover, there are two methods, which we will discuss in detail in this article.
Connection via cable
So, we have already dealt with the situation: you have a laptop, and the main monitor on the computer has become unusable. This is quite enough to solve the problem for a while. We will look at the first way to use a laptop as a computer monitor.
But in in this case still need to be purchased and used special cables to connect two devices. If you don't want to waste time searching for the perfect option, you can buy a VGA cable. It is significantly inferior in characteristics although functionally they are identical.
Please note that this option suitable only if you have a laptop based on the operating system Windows systems. If you have a Mac, you will need to purchase hdmi cable. It is with the help of it that the Apple laptop is synchronized and personal computer.
So, we’ve figured out what materials we need, now let’s move on to the instructions. How to use a laptop as a computer monitor?
Instructions
We have already figured out that you can use a laptop, but now we will find out how to do this using a cable. We will consider the VGA modification, since it is the most common, but this instruction should work for other options as well.
First, connect the cable to the appropriate ports on system unit computer and laptop. Now turn on your laptop. As you can see, no changes followed, but that's how it should be.
Right click on empty space on the laptop desktop. Select "Properties" from the menu. Now select “Display Properties”, and then go to the “Options” tab. There should be two rectangles in front of you with the numbers 1 and 2. Drag the two to the side on which your laptop is located relative to the computer.
Now confirm the changes if prompted and check the box next to "Extend to this monitor". Save the configuration and enjoy the result. Now you know how to use a laptop as a monitor using a cable.
Wireless connection of monitors
We connected the laptop as a monitor to the computer using a cable. But what to do if you don’t have a cable at hand, it’s night outside, and all the shops are closed, and you urgently need to work with computer files? If you have a laptop running Windows 7 SP3 or higher, then there is an answer! Can be done wireless connection. To do this, you need to use special application entitled - Air Display. If you don't have it, then it's time to install it.
This is another way to use a laptop as a monitor for a personal computer, but there are also various variations of applications. Most of them are analogues of the above, but do not under any circumstances think that they are worse. The only difference is in the manufacturer. It is recommended to install the programs and familiarize yourself with them. You don't need any instructions on how to use them: their interface is quite simple.
Separately, I would like to highlight the connection method via Wi-Fi networks. But we’ll talk about how to use a laptop as a computer monitor in this way below.
Connect using Wi-Fi
An application that allows you to transfer a picture from a computer to a laptop with using Wi-Fi, called MaxiVista. It will have to be purchased from official representatives of the manufacturer. However, it is possible to use a free demo version.
Once you purchase this program, you must install and configure it. Instructions for the application are provided by the developer himself.
Many of you have old or broken laptops that are lying around, but some of the spare parts in them are quite working, so it’s a shame to throw away the device. And if you suddenly want to do a second or third additional monitor for a computer, then this laptop will come in handy. Today I will tell you how to make a monitor from a working laptop matrix that can be used everywhere.
The first thing we need is a working laptop matrix. At this stage you must be 100% sure that it really works, otherwise execution next steps useless. So my patient - HP Pavilion dv9000, in which one of the display mounts is broken and the video module burned out, but the 17-inch matrix with a resolution of 1440x900 is working.
We carefully disassemble the laptop and remove the display, and then the matrix itself. For most devices on the network there is detailed instructions for disassembly. I also removed the speaker and webcam. As a result, we get approximately the following picture.
1) Jack for connecting LVDS cable.
2) A plug that connects to the backlight inverter.
We look carefully at the stickers and find the matrix model. As you can see, I have a laptop HP, and the matrix is from SAMSUNG, we are interested in the inscription LTN170X2-L02, this is the matrix model. The fact that after the “-” sign can be ignored when searching, only the marking is important to us LTN170X2.
If you don’t need any video inputs, then you can easily find, for example, a board with one of the inputs you are interested in. This way you can also reduce the cost of the device.
1) Input for connecting 12V power
2) HDMI input
3) DVI input
4) VGA input
5) Audio input
6) Audio output
The following components are included in the kit (they may vary slightly appearance and connection methods):
1) LVDS cable that connects directly to the monitor matrix.
2) An inverter responsible for the operation of the backlight.
3) Main board with controller.
4) Push-button interface for adjusting image parameters.
5) Cable for connecting the push-button interface.
6) Cable for connecting the backlight inverter.
There shouldn’t be any problems with the connection; you won’t be able to mix up the wires either. When assembled, everything looks something like this:
Next, we should check whether our device works at all. We connect the LVDS cable to the socket in the matrix; there is also a cable for backlighting on the matrix; we connect it to the free socket of the backlight inverter. We find it in the bins or buy a 12V power supply, perhaps one from your broken laptop will do. Be sure to check that the plug fits easily into the control board socket. Then we connect the video output of the computer to the video input of the control board with one of three cables (HDMI, DVI, VGA). We supply 12V by plugging our power supply into an outlet. Oops! Nothing happens. Like a regular monitor, the device has an on/off button. Press the button "ON\OFF" on a push-button interface. And lo and behold! We see the image. If you still have a black screen at this stage, check whether you have connected all the wires correctly, whether they fit well in the board sockets, and whether your power supply is working at all. I got it right the first time.
Next, this whole bunch of wires and boards needs to be beautifully mounted on the monitor. I screwed all the boards to the back plastic wall of the monitor, after drilling two holes for the LVDS cable and the backlight inverter cable, since they connect directly to the matrix. I also screwed two metal corners to the back wall so that I could easily place the monitor on the table. You can attach mounts to mount the monitor on the wall if necessary. This is what happened in the end, my brutal monitor =)
Where and how you can use this monitor:
The first two points only apply to video cards with multiple video outputs.
1) As an additional desktop. For example, you start a movie on one screen, and on the second you surf the net or type text. And there is no need to open\close, minimize\maximize interfering windows.
2) As a backup monitor. You can take him to another room and watch, for example, a movie or your favorite show there. My board has an audio input and output, so you can connect acoustics without any problems. It will also not be a problem to find a long video cable; I worked with a VGA cable, which was more than 20 meters long.
3) If you are familiar with Raspberry Pi, then you can also connect this monitor to it without any problems.
P.S. I will answer all your questions in the comments.
Welcome! This blog is dedicated to the Internet and computers, or rather was dedicated to them.
It’s probably immediately obvious that no new articles have appeared on the site for many years. Yes, this is the fate of most blogs. This project was once an ambitious undertaking, and the author, like many others writing at the time, had ambitious plans to become one of the best Russian bloggers. Well, if you look now, of those blogs that were created simultaneously with mine, most have already disappeared into eternity. And I just simply didn’t have enough time to blog. So yeah, it's not updated anymore. Although we once won the “Runet Blog 2011” competition with this site.
I even had the idea of deleting all this, but then I reviewed the old materials and realized that they could still be useful to readers. Yes, some articles are outdated (if I have enough strength, they will be marked accordingly), but the site, for example, can be useful for beginners - here you can read about basic concepts Internet, learn how to set up the Internet, Windows, or even decide to switch to Linux. So take a look at the categories and choose the one that suits you.
And yet, I hope that this is more than just a blog, but a real guide to the Internet. The site can be viewed in directory mode, where all available articles are structured by categories. And, who knows, maybe one day new high-quality articles will start appearing here.

Picodi.ru is a discount portal from International Coupons, a Polish expert in the field of savings and cheap shopping. The Poles are considered one of the most frugal nations in the world, so it is not surprising that this type of project grew out of the Polish startup kodyrabatowe.pl. How can this portal be useful to the average Internet user in Russia?
Modern Android phones are more than just phones. You get used to the set installed programs, to your call history and text messages, photo collections and much more. But time is running, and the device that suits you completely begins to slow down, glitch, or simply loses presentable appearance due to chips on the case or scratches on the screen. The question arises of choosing a new phone and changing android phone. And if we now bypass the question of choice, then “moving” to new phone remains a serious problem - I absolutely don’t want to start all the data from scratch. This is what we will talk about today.
Most of the readers of this blog have most likely never encountered version control systems and will not encounter them in the near future. It's a pity. This extremely convenient invention is quite widely used by programmers, but, in my opinion, it could also be very useful for those who actively work with texts. But, probably, now there is not a single version control system that would be easy to start using for “office” ( Microsoft Office) work. Nevertheless, I think that the material presented in the article may be of interest to all readers.
If you have been wondering how to watch movies online and access the Internet from your TV, this article is for you. No, I know that some TVs already have Smart TV functionality, but I have never seen it work properly. Apparently, this is why Google recently demonstrated an absolutely stunning device that immediately became a sensation. It's about about the Chromecast media streamer, a more advanced and available version last year's disastrous Nexus Q player.
Chromecast dongle, the size of which does not exceed 2 inches, is connected to the port HDMI TV and allows you to enjoy watching streaming web content. To control the streamer, you can use any device (tablet, PC, smartphone) based on operating platform iOS, Windows, Android or Mac OS.
This article is about the device system memory android, problems that may arise due to its lack and ways to solve them. Not long ago I myself was faced with the fact that my phone is on android base began to regularly display messages about low memory when trying to install this or that application. Which was very strange for me, given that according to the description on the market there should have been about 16GB, and I also increased this volume using an additional memory card. However, there was a problem, and I had to tinker a lot before I found the right solution that did not require root access or full recovery phone to factory condition.
Hello))) Today I will show you how to connect a laptop to another screen, or rather how to connect laptop to large monitor from your computer. I myself have done this several times, and I must tell you that this is a very convenient and interesting opportunity.
In this picture you see my laptop connected to the monitor from the computer. Everyone running programs and I manage folders from my laptop, and the whole thing is displayed on the monitor.
You can also connect a monitor to a laptop in a couple of minutes, and now I’ll show you how to do it.
First of all, inspect the connectors on your laptop. On one side there should be a connector for connecting a monitor. Typically this is a VGA, HDMI or DVI port. This is what they look like:
My laptop has a VGA connector.
After the connector on the laptop is found, we begin to inspect the monitor. Everything here is also simple - we need to find exactly the same connector.
Now we take the cable corresponding to the found connectors (in my case a VGA cable) and connect one end to the monitor and the other to the laptop. In this case, the laptop and monitor may already be turned on.
Great! Immediately after you connect the monitor to the laptop, you will see the picture from the laptop on the screen. It will be completely duplicated:
But it is not always necessary for the same thing to be displayed on the laptop and the monitor. And the screen resolution is usually set incorrectly by default! Let's learn how to configure all this.
Right-click on the desktop and select Screen resolution.
In the window that opens, you can immediately click the Find button if the monitor is not immediately identified.
Now pay attention to the section Multiple screens.
Here we can select the following screen operating modes:
1. Duplicate these screens. In this mode, the desktop will be displayed on both the laptop and the monitor. Everything we do on one screen will be completely duplicated on the second. It is convenient to use this function in presentations, when displaying data on big screen.
2. Expand these screens. In this mode, we get one large screen from the monitor and laptop screens. We can move programs and files from one screen (laptop) to another (monitor). Very convenient when working with several programs simultaneously.
3. Display the desktop only on the 1st or 2nd screen.
When you select this mode, one of the screens will display data, and the second will simply turn off. If you decide connect laptop to monitor, then most likely this is your case. IN this mode you need the image to be displayed on large monitor, and all commands were executed on a laptop.
On my own behalf I will only say that the first option is rarely used, and the second is most convenient when connecting two monitors to a computer. And the third, when you need to display the desktop on only one of the monitors, this is just our case, where the monitor is connected to the laptop!
Please note that when selecting the Expand screen mode, we have the opportunity to select the desired one for each screen individually permission. To do this, first of all, click on the screen thumbnail, and then select the desired resolution for it.
And finally, I want to give you a little hint. If you want to quickly switch between screens or use both at the same time, then use WIN+P. Pressing this combination launches a small program where you can select the multi-screen mode.
In Windows 8 and 10, this program looks a little different. After pressing the WIN+P combination, it appears on the right side of the screen, but the functions here are all the same!
This concludes my lesson! I wish you success in connecting your monitor to your laptop. See you in the next lessons.
