So I have tested the following:

- One HDMI cable, monitor to onboard
- Loaded factory BIOS settings
- Changed to Onboard and enabled iGPU under Chipset config
- Enabled CSM and forced 'Video OProm Policy'

Even with onboard graphics, STILL 1024x768.

- Tried disabling CSM again
- Reset to Dell factory settings

Not having any luck folks.

Not sure if this is solved but for me setting "Video OpRom Policy" to UEFI only and leaving all others as "Legacy only" enables HD in the UEFI.

This is on the Z270 Gaming K6 but should work on all ASRock 200 series boards.
