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!]]> Thu, 13 Aug 2020 11:20:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=9916&PID=77986&title=asrock-z370-pro4-full-hd-problem#77986 https://forum.asrock.com/forum_posts.asp?TID=9916&PID=57048&title=asrock-z370-pro4-full-hd-problem#57048 Author: Ajfel

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]]> Tue, 16 Oct 2018 21:51:42 +0000 https://forum.asrock.com/forum_posts.asp?TID=9916&PID=57048&title=asrock-z370-pro4-full-hd-problem#57048
