To get your PC to recognize multiple monitors: Make sure your cables are connected properly to the new monitors, then press Windows logo key + P to select a display option. If you need more help, here’s what to do:

Select Start , then open Settings .
Under System , select Display . Your PC should automatically detect your monitors and show your desktop. If you don’t see the monitors, select Multiple displays , then Detect.
Use the dropdown list next to the image of your desktop to choose how your screen will project across your displays.
Once you’ve chosen your setup, select Apply.

You can change the resolution of your displays. However, we suggest using the recommended resolution to get the most out of your displays.

Requirements: a suitable connection

By default, the majority of new laptops and PCs enable attaching a second monitor. All you need to think about are the ports on your end device and the display to which you want to connect. When you go out and buy one, make sure to look at the type and amount of ports on the laptop or PC. More displays can be added using the connections shown below:

HDMI
USB-C
DisplayPort
DVI/VGA

When just one port on a laptop is available, connect two monitors.

You can connect twin monitors even if your laptop only has a single HDMI or USB-C connector. You may simply connect two or more displays to your laptop by using an appropriate HDMI splitter, a USB-C dongle, or a USB-C dongle with HDMI interface.

Possible issues with two or more monitors

When connecting several monitors, Windows may fail to recognise older models. Choose “Detect” from the “Display” menu in this scenario. Another issue is that Windows may display a secondary monitor as the primary monitor.

To maintain your PC or laptop as your primary display, go to “Settings” > “System” > “Display Device” and pick the “Rearrange Display Devices” option. Then press the “Identify” button. On each screen, you should be able to see the given digit. Go to “Advanced display options” to modify the order.
