Windows 10 2004/20H2 Intel UHD Graphics 630 Black Screen with mouse cursor

I tried driver version 27.20.100.9025, 27.20.100.8935, 26.20.100.7210 all have the same problem

Symptoms

1. Black Screen with mouse cursor after screen saver / screen wake up after power plan turn off screen, only can fix by restart.

2. The Black Screen Monitor is connected to Intel UHD Graphics 630

2. If press Ctrl+Shift+Windows+B or Windows+E it might flash your desktop back for short seconds and goes back again or might not.

3. If you attach another monitor to Intel UHD Graphics 630, it will also be black with cursor.

4. If you attach another monitor to PEG/PCIE Graphics card, that monitor works fine

5. If you extend desktop with both Intel UHD Graphics 630 and the PEG/PCIE Graphics Card, you will find that when you click on the black screen, actually it works, Windows response to your mouse click when you click on the location start menu or open applications even if it is black.

Solution

1. Repeat the following steps until there is no Intel drivers left and it uses Microsoft Graphics Adapter driver

    a. Uninstall Intel(R) UHD Graphics 630 in Device Manager with "Delete the driver software for this device" checked.

    b. Right click on your computer and click "Rescan for hardware changes"

2. Windows 10 will use the default Microsoft driver for a few minutes and install Intel(R) UHD Graphics 630 again with driver version 27.20.100.8681

3. Enable OS APSM and Disable all other PCI APSM in BIOS, 

4. Install the newest driver 27.20.100.9079 should solve the problem

the above steps fixed my problem,
