" rel="nofollow - Hello,

I have artifacts on BIOS boot select screen (F11), like extend pictures
I updated BIOS, clear CMOS and it still the same.
I think it is a problem and want to fix it. 
Should I send to RMA or other ways can help me?

Dear Ragna-Gauche,

Greetings, this is ASRock TSD.


We have tested the board in our lab, the screen is working normally.
There are some suggestions for verifying:

1. Please do not connect any USB devices and then check again.
2. Please connect another output display to verify.
3. If possible, please change another cable to verify.


Thanks!

All the best,
ASRock TSD

I too have this on my X370 ITX/ac it looks like part of the picture has been displaced no the right and bottom side, but just in the F11 boot screen, I think it started after a UEFI update (I think 3.60 or something in the 4.xx range)

feel free to try with csm enabled/disabled
otherwise screen can get corrupted in uefi if your ram has errors
