Windows Touch Screen With Multiple Monitors Puts Cursor On Wrong Monitor

Windows 7 is capable of this as long as the final step doesn't confuse you in what someone else already answered. I will try to explain the last step a little clearer.

1. Press the Windows Key and type then click "Tablet PC Settings" listed under Control Panel.

2. Click "Setup..."

3. Keep pressing Enter until the text is written on the Touchscreen, then touch it!

Windows will then know what input (Touch) device is associated to which screen. :-)

Windows 10

1. Go to Windows Settings (WinKey and search "Settings") and search for "calibrate the screen for pen or touch input"
2. or: Run -> "control /name Microsoft.TabletPCSettings"
3. Click the "Setup..." button
4. Click Enter until you see the message on the screen you want

Can you list what you've tried?

Windows 7

My first port of call would be display settings: Control Panel -> Settings -> Display -> Screen Resolution - set the the touchscreen monitor you wish to use as your Primary display.

Unfortunately in Windows 7 in a dual monitor setup, from experience, your touch screen will have to be the Primary display.

Windows 8; if you have both a touchscreen and non-touchscreen monitor connected to your PC, you might need to change settings for your cursor.

Swipe in from the right edge of the screen, tap Search (or if you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Search), enter Tablet PC Settings, and then tap or click Tablet PC Settings.

Tap or click Setup. Administrator permission required You might be asked for an admin password or to confirm your choice.

If you’re given a choice, tap or click Touch Input, and follow the on-screen instructions.

Hope this helps :)
