Hmm sorry, I am not sure what else to try! Maybe setting 59Hz as the refresh rate in the Intel Graphics?
I just noticed that Gigabyte published an updated firmware a few days ago for the MC2800 chip to v1.61 (MCDP2800_C21_C22_V1.61.00_LSPCON_MP_SIGNED_CMDB.BIN) - File dated 28 Nov 2016.
Will give this one a go once ASRock update this on their support page. Don't really want to be flashing firmware if not provided/tested by ASRock.

I have experienced this on UEFI 7.10 and 2.30 so far in the last few days. I have now rolled back to 2.10 to try on that. Will keep going back to see if it happens on them all. It may be a driver issue, but I was having difficulty getting the UEFI to display when using HDMI2 this morning - worked straight away once switching over to HDMI1.
