To connect a large number of displays to one computer, you need to configure the synchronous operation of two video cards. This will allow 3 or 4 monitors to be used stably at the same time.

two video cards
Instructions
Step 1
Find the set of video adapters that you will be using. In most cases, you can get by with an integrated video accelerator and a discrete video card. If your motherboard does not have a built-in video adapter, then use two full-fledged video cards. In this case, it is better to purchase identical models of video cards, but you can also use devices from different companies.
Step 2
Connect both video cards to the motherboard and turn on the computer. Install the software required to configure both video adapters. Naturally, if you use different video cards, then install two sets of drivers, each of which will ensure the stable operation of a particular adapter.
Step 3
Connect video cards to external displays. If you are using a TV or TFT panel, it is best to connect them through channels that carry digital signals, such as HDMI or DVI-D. Even if there are three channels in video adapters, it is better to use 2 + 2 pairs rather than 3 + 1 pairs. This will allow you to more or less evenly distribute the load between the video cards.
Step 4
Open TV settings if you are using these devices. Specify the required ports (through which you have connected) as the main video signal source. Turn on the computer and after loading the operating system go to the menu "Connect to external display". If not all new screens are displayed at the top of the window, click the "Find" button.
Step 5
Customize the collaboration settings for the displays you want. First select the main unit and activate the corresponding function. Now select the graphics of the other three displays and activate the "Extend to these screens" item. Remember that when using video cards from different brands, there may be problems with driver compatibility.
