After buying a new computer, the problem arises - how to connect the monitor to the system unit? In fact, it is not difficult, the main thing is that the connectors match. It is best to see which connector on the screen and on the unit before purchase - in this case, the connection will take a couple of minutes. However, even after a seemingly successful connection, the monitor remains black after turning on the PC. What to do in this case? Let's figure it out in order.
What are the cables for connecting
The hole for connecting the cable to the monitor is the largest in the block. In order for the wire to hold well, it is fixed using screws that are already provided by the manufacturer.
Modern units and monitors are equipped with the following types of cable connectors:
- VGA is a fairly old connector, but still found in low-cost technology. It connects with it even to the oldest models, but the image is almost always of poor quality. A VGA port should be used only if there are no other connectors;
- DVI is the best interface, it conveys the most juicy and clear image. If it is in the block and screen, then you need to connect through it;
- HDMI - a standard connector that exists in most connectors, transfers a good quality picture, supports video format, transmits 4K image (but only low frequency).
The cable required for connecting to the processor is selected depending on the socket. Of course, it is most convenient to use VGA - wires for such an interface are inexpensive and are sold in any hardware store. As a rule, the cable you need comes with the monitor.
Using the selected cable, you need to connect the connectors in the system unit and the monitor. Check if everything is connected securely and firmly. Insert the cable from the monitor into a power outlet. It is most convenient to use an extension cord (pilot). After that, turn on the computer and the screen - if everything is done correctly, an image will appear on the monitor.
Using Explorer
The monitor cable is not always suitable for connecting to the connector on the computer itself. In this situation, the conductor will help. It will also help if there is simply no port. The conductor has two different sides - one is connected to the screen hole in the unit, and the other serves to fasten the wire of the desired connector. Using cables, the monitor is also connected to the system unit or video card.
After that, you just need to connect the computer and the monitor using the selected cable and check their operation.
IMPORTANT! The adapter is inexpensive, the main thing is not to make a mistake with the holes and buy the necessary for your wire and equipment.
How to make a connection - instructions
Connecting a PC to the screen is not difficult at all - you can do this in a few steps. In order not to look for connectors for a long time, you need to know where the video card is located in the unit - this is where the connection will be. So, the step-by-step instruction is as follows:
- Find the cable that plugs into the outlet, and the cable that will connect to the system unit next to the video card;
- Connect the wire to the outlet, check that it works;
- find the hole into which the cable from the computer will be inserted, check if it matches the cable;
- gently, without strong pressure, connect the wire to the connector and tighten the screws, check the connection;
- turn on the computer and wait for the picture to appear.
IMPORTANT! Many modern system units have several connectors at once, before connecting, you need to see which one suits the cable. The holes on the block say what format they are.
PC and monitor compatibility
It often happens that everything is connected and should work, but the image either does not appear at all or is of very poor quality. What is the problem? The video card that is responsible for displaying the picture does not work with the connected screen.
Before buying, you need to decide which diagonal the computer can work with. The larger the screen, the greater the load on the video card and on the system unit as a whole.
It is important to understand what the monitor is bought for:
- for games - a large monitor with high resolution, for this you will need a powerful video card;
- for work and surfing the Internet - a simple screen is also suitable, the load on the video card will not be too big;
- for drawing - you need a wide screen with a high-quality picture and a good video card.
When choosing and buying, pay attention to the connectors of the video card and monitor - if they do not match, you must either buy an adapter or choose another model.
IMPORTANT! If the video card is suitable, the wire is selected correctly, but the graphics leave much to be desired - it is worth updating the driver.
Why the processor can work, and the monitor does not turn on
It also happens that the computer itself is working, but the picture does not appear. The reasons why this happens are many:
- The most commonplace - the monitor is not turned on (the Power button is not pressed);
- the monitor is not connected to a wall outlet or system unit;
- there is a malfunction of the video card;
- the necessary drivers are not installed;
- there are problems with the motherboard.
If the computer is turned on and the monitor does not work, first check whether the power button is on. You can press it several times, it is possible that the button is “stuck”. If the Power button is not lit at all, then the problem is in the monitor. What can be done? Try changing the cable or reloading the screen.
If there is no image when turning on, but the screen changes light (blinks or brightens), then the problem may be in the cable. Adjusting the brightness can help (it happens that the brightness settings are at a minimum and the screen appears black). If something is wrong with the computer, a window will appear on the monitor that there is no signal.
Be sure to check the cable - it may be bent or poorly connected. The screws often break and the cable weakens. Ideally, completely replace the wire and turn on the equipment again. If, after this, the problem persists, you should contact a specialist, because it is the problems in the system that work.
IMPORTANT! During all manipulations, the computer and monitor must be disconnected from the network.
If a new video card or motherboard has been installed, they may not be compatible with the screen. To check this, you need to connect the monitor to another computer, or examine the video card. Most often, if this is the problem, pops are heard when you turn it on.
It happens that the processor is broken and not because of this the image is not shown. In this case, the computer is noisy as during normal operation.
IMPORTANT! If the fault lies in any part of the system, then only a professional can help. It is he who will be able to identify the problem and, if necessary, replace the parts.
Recommendations
Despite the fact that the connection itself does not require any special skills, some problems may arise during the process. To avoid them, it is worth reading some recommendations.
- choose a monitor depending on the work that will be carried out for him;
- Before buying equipment, figure out which ports are available and which cable will need to be purchased; you may need to buy an adapter;
- check for drivers;
- buy a reliable extension cord to connect all the equipment in one "pilot";
- check the compatibility of the video card with the screen;
- insert and secure the cable into the port carefully, do not press hard on the screws;
- after connecting, check the operation of the equipment, adjust the saturation, brightness parameters.
IMPORTANT! As a rule, the operating system automatically installs the necessary drivers the first time it is turned on.
If this does not happen, you will have to install them manually. A driver disk may come bundled; otherwise, they are easy to find and download on the Internet.
Thus, the independent connection of a new monitor to the system unit of a computer does not take much time and effort. Of course, it is necessary that the ports of both devices coincide, and the cable is correctly selected. If you encounter any problems after connecting, you should check the reliability of the cable and connectors, the compatibility of the individual components of the computer with each other. If you follow all the recommendations and carefully connect the screen and the PC using the cable, then there will be no problems, and the bright picture on the new monitor will please the user for a long time.
