# TSG: Touch input goes to the wrong display on Windows

## Overview

On Windows, if you have a pen display that supports touch, you may find that if you touch the pen display, it will act as if you are touching a different display.

This is a common thing people run into with displays that support touch on Windows. It's not the fault of the pen display and it can be easily fixed.

## Background

When you attach a device that supports touch input, by default Windows will map its touch input to the "main display". And most often this will NOT be your pen display.

## OPTION #1: Set your pen display to be the main display

* Open Display Settings
* Click on the display that corresponds to your pen display
* Enable "Make this my main display"

## Option #2: Configure Windows to send touch input to a different display

* Open **Control Panel**
* Find and open **Tablet PC Settings** (you can search for it in the Control Panel search bar)
* In **Tablet PC Settings**, under **Display** > **Configure** tab, click **Setup**
* Select **Touch input**
* On the screen you'll be asked to follow some instructions to identify which display touch should go to. Follow those instructions. The procedure will flow like this:
  * One of the screens will go all white
  * If that is the screen where you want to have touch go to, then touch the screen
  * If it isn't, then hit ENTER to try a different screen. In turn that screen will go white and the process repeats
  * The procedure ends the moment you have touched one of the screens.

* By default, touch on the tablet will normally map to whichever display is your "main monitor".
* You can map touch back to the tablet when it is not the main monitor. See this document from Huion: [How to make finger gestures control Kamvas Studio 16/Kamvas Pro 19/Kamvas Pro 27 instead of the external monitor](https://support.huion.com/en/support/solutions/articles/44002416035-how-to-make-finger-gestures-control-kamvas-studio-16-kamvas-pro-19-kamvas-pro-27-instead-of-the-exter). When I first tried this, it fixed the touch problem, but it had an odd interaction with the pen - when I used the pen on the tablet, the pointer always stayed near the top border. After I uninstalled the driver, restarted the computer, and reinstalled the driver, the problem went away and the pen worked normally.
