1. Checklist of things to do before Connect Multiple Monitors with one CPU:

Most modern Windows CPUs support multiple screens at the very least. However, you must ensure that your computer is capable of supporting two external displays. It is determined by the capability of your graphics cards and drivers, as well as your Windows operating system.

1.1. Examine the graphics card:

First and foremost, check to see if your graphics card supports multiple displays. Normally, every graphics card has at least two outputs, but you will need to check the graphics card attributes on the manufacturer’s website, identify your graphics card, and verify the specs to determine whether it allows attaching two external displays.

For example, if you have an NVIDIA GeForce graphics card, pick your graphics card, and check the specifications to see if it supports multiple displays.

If it does not enable the additional monitors, you may need to purchase and install a suitable graphics card before proceeding.

1.2. Check available ports on your PC || Connect Multiple Monitors with one CPU:

Then you should look at the ports on your system. In general, a system should have one of the following four ports:

  1. Display Port can offer a high-definition audio interface with content material security.
  2. Digital Video Interface (DVI) connectors are often color-coded using white plastic and labels.
  3. VGA (Video Graphics Array) is often color-coded with blue plastic and labels.
  4. The High-Definition Multimedia Interface (HDMI) cable may link various television devices as well as offer sound.

Examine the ports on the back and sides of your system. In addition to the connections on your CPU, the monitors should have the same ports. It will save you time and money to link them this way. Otherwise, you’ll need to purchase an additional converter, such as a DVI to HDMI adapter, to make them match.

If you don’t have matching CPU and monitor ports.

Don’t give up if your PC’s ports don’t match your monitor’s cable connections. There is an alternative! To proceed, you can use one of the ways listed below:

  • Make use of an adaptor, such as an HDMI to DVI converter. This works if your device and screen have different ports.
  • Use a transfer splitter with a Display splitter to get HDMI ports. This works if your system only has one HDMI port and you require two HDMI ports.
  • It works in a variety of situations if you use a docking station.

2. How can I connect Multiple Monitors with one CPU?

Since everything is ready, you can start connecting the two monitors to your system.

While your CPU is on, connect your monitors. When you plug in a new monitor, Windows will usually detect it.

For example, I have VGA and HDMI ports on my CPU, and my external monitors have cables for VGA and HDMI ports as well:

  1. Connect the first external monitor’s cord to your CPU’s video port. So I connect the VGA cord from the first external monitor to the VGA port on my system.
  2. Connect the second external monitor’s cord to the other appropriate CPU connector. As a result, I connect the HDMI cable from the second external display to the HDMI port on my system.
  3. Right-click an empty space on your desktop on your CPU and select: 
  • If you’re using Windows 10, go to Display settings.
  • Click Screen resolution if you’re running Windows 8/7.

4. In-display mode, you may see 3 monitors categorized as 1, 2, and three. Display 1 is your system’s primary monitor, while displays 2 and 3 are secondary monitors.
5. Display 2 should be clicked. Select Extend desktop to this monitor from the Multiple displays column, then click Apply.


6. In the 3rd Display, choose the Multiple displays column, then choose Extend desktop to this monitor, then click Apply.


7. Click OK to save the changes, and you may now use your system’s three screens.
Please keep in mind that you may alter the display by clicking and dragging each display (1, 2, or 3). You may also alter the size of things, the display quality, and the orientation to suit your needs.
