Detailed description:
When I bought this Zenbook Duo UX481FL, the touchscreen on the second screen display was available and functioning well.
When it was fixed by ASUS Service Center for some heat and power issues, the touchscreen was not anymore available.
How can we put the Touch Screen of the second screen display back?
Appreciate highly your help on this matter.
Thank you!!

Hi there,
Sorry, I'm confused. The 2 screenshot is related to the main screen. So can you specify more ?
And may I double check if the issue happen after you upgrade to Win 11?
You can follow below FAQ to reinstall the drivers for Screenpad plus
[Notebook] Troubleshooting - How to fix the ScreenPad Plus problems when it is not working properly ...Please be careful that the installation order must be followed.
And if you can help to provide a picture of how your screenpad looks like now would be helpful.
Thank you.
