Hi, Did you get this sorted?
I have the same motherboard using HDMI, with an i3 3225 CPU (So we match on HDMI, HD4000 and motherboard). My Bios screen is really zoomed in when I boot, I can't see any of the bios options (F Keys), I've not tried pressing F8 or whatever it is to actually get into the bios as I assumed it would be unusable being so big and I didn't want to get stuck.
I've set my TV so it's not overscanning and once I boot into windows all is great in 1900x1080 but the BIOS remains Zoomed on boot.
I would like to get this fixed as I'm sure I'll need to go into the bios at some point lol.
Thanks,
FoxTC...
