DIY. We make a monitor from a laptop matrix. Guide to the Internet - all the most interesting things on the Internet I broke my laptop screen, how to connect a monitor

Sooner or later, everyone thinks about improving or increasing the capabilities of their laptop. The most common and fairly simple method of modernization is connect a second monitor to the laptop via VGA connector. In the same topic you can also consider how to connect a projector to a laptop, since the algorithm of actions in these two situations is absolutely the same.

If our devices are functioning normally, then we only need to perform 3 simple steps:

1. Turn off the laptop.
2. Connect an external monitor (or projector) to the laptop via the VGA port.
3. Turn on the monitor (projector), then the laptop.

Let us explain this algorithm. It is better to connect for the first time with the laptop turned off, as some laptops check for the presence of a second monitor when booting. Our second screen is connected via a VGA port (rarely DVI).

After turning on the laptop, an image should appear on the external monitor. If this does not happen, and the computer boots, then we have to supplement the above procedure:

4. Manually switch the laptop to an external monitor.

To do this, you should carefully study a number of function keys on the keyboard (F1, F2, ..., F12).

The F4 key is responsible for switching the monitor operating mode

Depending on your laptop model, one of the function keys on your device is responsible for switching the screen to an external monitor or projector. This could be F1, F4, F5 and others. If nothing happens when you press it, then you need to use a key combination, for example Fn+F1 or Fn+F4. If again to no avail, you can use - Win+P (P-English).

We figured out how connect an external monitor to the laptop, however, they did not consider the nuances of such a symbiosis. Let's go to the following links:

Start -> Control Panel -> Display -> Adjust screen settings

Here we can specify which screen will be the main one and which will remain secondary. This menu can also be useful when we place the second monitor to the left or right of the laptop, and select its appropriate position in the settings. Actually, complete connecting a monitor to a laptop remains an indication of the optimal screen resolution and orientation parameters.

Using the same “hot keys” F1, F4, Fn+F4 or others, you can set the screen operating mode (your modes may be called differently):

1. Extend - the laptop screen and external monitor work separately.
2. Duplicate - the image on two screens is the same.
3. Turn off the projector (external monitor).
4. Projector (monitor) only - laptop screen is turned off.

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 the basic concepts of the 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 passes, and the device that you were completely satisfied with begins to slow down, glitch, or simply loses its presentable appearance due to chips on the body 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 affordable version of last year's disastrous Nexus Q player.

The Chromecast dongle, whose dimensions do not exceed 2 inches, connects to the HDMI port of the TV and allows you to enjoy watching streaming web content. To control the streamer, you can use any device (tablet, PC, smartphone) based on the operating platform iOS, Windows, Android or Mac OS.

This article is devoted to the design of the system android memory, 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 it took a lot of fiddling around before I found the right solution that didn’t require root access or completely restoring the phone to its factory state.

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 make a second or third additional monitor for your 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 point, you must be 100% sure that it really works, otherwise, following these steps is 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.

First of all, look at the connectors on your laptop. On one side you will find a connector for connecting an 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. There are 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 is a VGA-miniVGA cable.

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.

Configuration can also be done using specialized utilities. For example, if you have integrated video from Intel, then right-click on the desktop to open the graphics settings and then, as shown in the picture.

Algorithm connecting the projector similar.

– practically not inferior in performance to full-fledged ones desktop computers. At the same time, the laptop user is not tied to one point and can move freely with his PC. Therefore, recently more and more people prefer to use a laptop as their main computer. However, when used at home, the laptop has one drawback - a small screen. To neutralize this problem, you need to connect a full-fledged one to the laptop. In this material we will talk about how to connect a monitor to a laptop.

To connect the monitor to the laptop first

VGA is the most common interface and can be found in almost all laptops. VGA is an outdated analog interface. However, it is still quite relevant and can be used to connect or projector to your laptop without any problems.

HDMI is also a very common interface for connecting a monitor or. Often used in conjunction with VGA. The port can also often be found on other computer equipment. For example, on tablets or smartphones.

DVI- perfect option to connect a monitor to a laptop. On this moment considered the standard for connecting monitors. However, the DVI interface is quite rarely found on laptops.

DisplayPort is one of the newest interfaces for image output. Recently it has been rapidly gaining popularity and can be increasingly found in laptops.

After you have examined your laptop and determined what interfaces it is equipped with for image output, you need to do the same with the monitor. In general, you need to find interfaces that are available on both the monitor and the laptop. With their help you can connect your monitor to your laptop.

To connect the monitor you just need to connect two identical ports on the monitor and on the laptop using a cable suitable for the ports. After this, the laptop should detect the additional monitor and the picture from the laptop will appear on it. If the monitor is not detected after connecting, restart the computer.

A situation may also arise when you do not have the same ports on your laptop and monitor. For example, a laptop is equipped only with an HDMI port, but the monitor does not have an HDMI port. In this case, you will need adapters.

Now you can find an adapter from almost any interface to any:

• DVI – VGA;
• DVI - HDMI;
• HDMI - VGA;
• DisplayPort - DVI;
• DisplayPort - HDMI
• etc.

Setting up a monitor connection to a laptop

After you have connected the two ports, a picture from the laptop should appear on the monitor screen. However, working in duplicate screen mode is not always convenient. To change the mode you need to go to “Screen Settings”. To do this, right-click on the desktop and select “ ”.

In the window that opens, you can select the mode for displaying images on connected screens. The following modes are available:

• Duplicate screens. In this case, both screens will work simultaneously, both on the laptop and on the monitor. In this case, the picture on both screens will be the same. This mode is especially convenient when connecting a projector or monitor to demonstrate presentations.
• Expand screen. In this case, the connected monitor will expand the screen of your laptop. By choosing this mode, you can work with two screens at once and move windows between them.
• Display desktop on 1 (or 2) only. In this case, you select only one of the screens. While it won't work. This mode is suitable if you only want to work with a connected monitor.
