Clone mode be changed to extend mode when sleep resume loop test

Question

Hi, Microsoft,

we encountered an issue as below,

A system with eDP monitor and connect a 2nd monitor (resolution is 1024x768) by DP cable.
then let system to do S3 sleep and resume loop test.

Before test, we set clone mode for both display, then run S3 resume loop test.
It failed at 225 cycle, the clone mode is changed to extend mode,
and the resolution of 2nd monitor is became to 640x480 and user can not modify it.

When user press the Touch Panel on the eDP monitor, the cursor is shown on 2nd monitor.

Does MS have the solution or workaround to fix this issue?

• Windows 10 IoT Enterprise LTSC 2019 64 bit
• Intel Tiger Lake platform

Thanks & Regards.
