Acer Swift3x-510G-503B Screen Flicker

Encounter screen flicker on day 1. All Win10 updates done - 20H2 OS build 19042.1288. Intel Iris Xe Graphics driver - 27.20.100.9466, Iris Xe MAX Graphics driver - 27.20.100.9466. Even tried to remove Symantec Norton, disable Win Error Reporting as recommended in some videos, still no help. Also do Windows Reset, still no help. BIOS screen and Windows Update timer screen stable. Finally diagnose to be suspected wifi adapter Intel Wifi 6 AX201 160MHz - update to driver 22.80.1.1, and then connect to my router using Wifi 5 (802.11ac) 5 Ghz band, only then the screen flicker disappears. I tested to connect to the other wifi 4 (802.11n) 2.4GHz and instantly, the flickering reappears!

Hi @HenryLee,

# Try to get the BIOS page.

1. Turn OFF the unit.

2. Press and hold the F2 key and turn on the unit.
3. You will be in setup utility page.
4. Once you got the screen release the F2 key.
5. Tap on F9 key and hit enter key without changing the option.
6. Tap on F10 key and hit enter key without changing the option.
7. Your unit will restart by itself.

Check this T/S and post the result.

OK, if the screen doesn't flicker in the BIOS try booting in Windows Safe Mode with Networking. Try and reproduce the flicker symptom there. Safe mode will disable a bunch of the GPU features yet the Networking option will allow testing at 2.4GHz still. Since the symptom requires Windows to be loaded we know it's not just hardware...
