How to connect two monitors to one computer

Many modern gadgets boast the presence of several video outputs at once. Usually they duplicate each other. Most often, these video outputs are either VGA or DVI. Connecting two or even three displays to your computer is extremely simple. You do not need to be a programmer for this.

Connection

Problems can arise only if the computer has 1 video adapter (this is quite rare), as well as 1 output to the monitor.

Moreover, the total number of monitors that can be connected to one personal computer is often quite unlimited. In some cases, you can even create a full-fledged video wall, which consists of a couple of dozens of different devices. For an ordinary user, two or three monitors will be enough. Modern technologies allow you to connect them even if only 1 video card is installed in the system unit.

REFERENCE! It is desirable that no more than 3 monitors fall on one video card. In this case, everything will work perfectly. In addition, you can connect monitors even if it is just a video adapter that is built into the processor.

Connecting multiple monitors to a computer at once will solve a number of problems that are relevant for so many users. In particular, those who work at a computer often need additional space to solve some problems. This applies not only to designers or programmers, but also to representatives of other professions.

The second monitor will allow you to perform almost any task with much greater efficiency and in a shorter time. Also, a second monitor can be called a necessity when one screen does not have enough free space for work. This can be especially important for designers who are constantly experiencing a lack of work space.

Modern technology has become so versatile that in most cases, users can not even worry about the fact that multiple monitors cannot be connected to their computer. This is usually possible if the video card has several outputs (connectors). Finding them is easy. They are located on the back of the system unit, where most wires lead. If the output is only 1, then you should use a device called a splitter. You can learn about the features of using a splitter from the sections of the article below. We can add that the splitter is quite cheap, so even owners of very old computers can purchase it.

REFERENCE! Also, before connecting, you need to make sure that all the connectors are in good condition. It happens that they are covered with a layer of dust. In this case, it is recommended to get rid of it as soon as possible.

Usually, in order to find out which cables are required for connection, you need to know the type of connectors on the monitors and computer. It can be either digital, or analog, or HDMI output. Naturally, each of these connectors requires a specific cable. Finding cables on the open market is extremely simple if they are not at hand.

The first step is to inspect the computer. You must make sure that there are at least several outputs in the system unit. Only in this case can you be sure that no problems will arise. If you are talking about any new laptop model, then you can not worry, because they are always equipped with at least two outputs to the screen or projector. You must also keep in mind the type of connector.

The second step is to connect. Do not forget that before starting the connection, you need to connect both monitors to power sources. It is best to do this directly to the network. It should also be borne in mind that unplanned disabling of the integrated output of a video card is possible. This usually happens when the PC has a video card, as well as a special special accelerator (graphic). In this case, you can expect an unplanned outage at any time.

Experts recommend connecting both screens to an external video card, or through the motherboard. After the connection process is completed, you should restart your computer until another display is fully initialized.

The simplest methods in which both screens will function normally:

1. Connect them to any of the free ports.
2. Use a splitter. It is required if the video card has only 1 output. Then you cannot do without it.

Today, HDMI is called the most popular graphical interface. It is characterized by high speed and other technical characteristics. That is why it can be used to transmit images with high definition. Also, analog output and digital have earned wide popularity. They are already obsolete, but are still found on some monitors.

REFERENCE! Displays that have only an analog output have their own characteristics. They will have to use a splitter.

This device is indispensable when it comes to duplicated ports. There is also another problem with the analog output. The fact is that many modern computers do not have such a connector. As a result, in order to connect the PC to the monitor, you also have to use an adapter.

Small adapters are very similar to ordinary matchboxes. It is possible to connect an ordinary PC to several devices just because on such an adapter one of the sides is the analog port, and the other side is the digital port. When connecting a second monitor, act as carefully as possible. Otherwise, a variety of problems may arise. Moreover, sometimes mechanical damage may occur at all. They can cause equipment damage.

With digital output, everything is much simpler. You will need to first carefully examine the system unit and find several outputs on the video card. It is important to follow the connection rules, otherwise the connectors may be damaged. In the case of a digital output, you can also use a splitter. This plastic device can be called universal, because with it you can connect everything you need.

The process of setting up multiple screens is automatic. This is very important, because only in this case the user does not have to "dig" into the settings on his own. You just need to follow the instructions that appear on the PC display.

One advanced configuration may be required if the user is engaged in some complex tasks directly at the computer. In this case, he can not do without additional configuration. Then he can easily duplicate the working interface of any program on several screens at once. If we are talking about a laptop, then the user will be able to display a picture on only one of the devices.

• To start the setup, you need to hold down a certain key combination. This is a combination of Win + P. In the newly appeared window, you will need to select a specific mode of operation.
• Another configuration method involves much more complex operations. In particular, you need to open the context menu directly on the desktop. After that, click on the “Screen Resolution” menu. It is here that you need to find one of the lists, which is of interest to us. This list is called Multiple Monitors. Then you need to choose some specific mode of operation. This can be either duplication or expansion. Depending on which mode of operation is selected, the displays will work in a certain way.
• It should be noted such a function as the extension of the picture. If for some reason interference or other technical problems occur, you need to check all the settings of the video adapter. An alternative is to download new drivers from the manufacturer’s website. In this case, all problems, including annoying stripes along the edge of the home screen, will disappear immediately.
• You can also select one of the display modes. For example, the total monitor space can be divided into several parts.
• You should know that if we are talking about completely different monitors with different technical characteristics, you need to choose a lower value as the resolution. In this case, you can forget about the "glitches".

After all the connection steps have been completed, you need to solve a whole series of issues. In particular, the user needs to find a program that will complete the connection of devices. One of the most popular programs is Dual Head. She is able to remember all the actions of users when they work with two screens. After the computer is restarted again, it will turn on and make sure that all the settings that were set by the user during the first use are saved.

Those who have a graphics card from AMD can recommend the Hydravision program. With its help, it is possible to set the same resolution, as well as solve any shortcomings that users may encounter when using multiple screens.

Also, additional programs may be required in order to install a taskbar on each of the screens. In addition, with the help of programs, you can make it easier to use screens if the user is engaged in drawing. Then he can not do without additional software. Let's hope that the information presented helped set up the monitor and made life a little more comfortable.
