When you plug two or more monitors into a desktop PC, Windows should automatically detect each new monitor and provide you with multiple display options. You can choose to:
-
Extend these displays. This spreads your desktop over both monitors and lets you drag items between the two screens. This is how most people use two monitors, and it's the default setting.
-
Duplicate these displays. This displays the same desktop on both monitors. For a laptop, this is the default setting. This is useful if you're giving a presentation with your laptop connected to a projector or large monitor.
-
Show desktop on only one monitor. This is most commonly used with a laptop if you might want to keep your laptop screen blank after you connect to a large desktop monitor.
When using multiple touchscreen displays in Windows, the touch may not work properly and require calibration.
Use the following steps to calibrate each touchscreen display independently:
Please Note: Be sure there is no GPO or Security Policy blocking/removing this function in Windows 10 & 11….
- Be sure all of the displays are set to "Extend these displays" in the Windows Display Properties
- Go to settings and search: "calibrate the screen for pen or touch input"
- 2) Click "Setup" on "Configure your pen and touch displays"
- 3) All screens go white. On main screen you will see a message saying: "Tap this screen with a single finger...". Press Enter key until you see that message on your touch screen.
- 4) Touch the screen
- 5) When prompted press Enter
- 6) Touch the next screen
