Matebook X Pro 2018 Blank Screen after Test Starts

[Matebookxprohelp]

Tried on the latest version and the beta version downloaded today, boot fine and the test countdowns, but when it starts it just goes grey/black blank screen. Tried multiple times.

I've attached what I believe is the log file. Please help. Thanks

Looks like there is a UEFI BIOS bug when attempting to adjust the screen resolution.

Can you edit the blacklist.cfg file under the EFI\BOOT folder of the USB flash drive and add the following line:

"MACH-WX9",ALL,EXACT,FIXED_SCREENRES

Then try running MemTest86 again.

Thanks I can see the test running now, but it's very small, 3inches by 3 inches in the middle of my screen. But still readable, it is a 4k display...

Report the problem to Huawei and ask them to fix their UEFI BIOS. I am 100% sure they won't care however.
