Somehow after loading one of my UEFI Profile the screen flickered and moved my UEFI to my secondary screen which is running DVI and is set in portrait. My Main is on displayport but the strange thing i've been using this setup on this board for a few weeks now and uefi always been on the main screen. Things i've tried are rebooting without the secondary a few times but it will display on the secondary as long its plugged in enable/disable CSM doesn't seem to have an effect just wondering if you guys have any other suggestions before i hit the clear cmos -------------

When it boots, the "ASRock" logo normally appears and in the bottom right corner it gives options, such as "Press F2 to enter setup". One of these options is "Press Tab to switch screens". Try that out. I think I found that after installing the OS (Windows 10) it has always stayed on the DisplayPort and not HDMI for me. However, this is with a discreet GPU and an X370 board, so... ------------- X370 TaiChi | 1700X P3.10 stock clocks | (2x 16GB) 32GB FlareX 2400MHz. https://valid.x86.fr/ikadaa" rel="nofollow">
