ASRock Z370 PRO4 Full HD problem.

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi there,

UEFI doesn't want to work in Full HD mode. In UEFI settings I have "auto" option for 1080p and have disabled CSM (because with enabled CSM I even had Windows boot in 1024x768).

Is there anyway to fix this so UEFI will work in Full HD mode?

MB: ASRock Z370 PRO4
GPU: MSI GAMING X GTX 1080Ti
Monitor: ASUS ROG SWIFT PG278Q connected by DP cable.

Thanks for any helpful information

	Hi sorry, I have no solution for you (and its much later, did you solve your problem?). But maybe you can help me. I want to run memtest86+ on a machine with this mb, but I cannot find how to set CSM mode in the bios. Can you say where and how this is done? Thanks!
