Can't see UEFI properly

[Squall88uk]

I recently built a new system and it seems to be working fine. Windows 10 is installed and everything seems ok. For some reason I am unable to access the UEFI. I am able to interrupt the boot process and it tries to load the UEFI but all I get us the mouse cursor. If I move the mouse around I can make it "paint" The uefi background image as I move the mouse but I cannot interact with the UEFI in any way.

The only way I can get into the UEFI is to remove my graphics card and then plug my monitor into the integrated dvi port of the motherboard. The PC itself works fine via HDMI with my graphics card just not the UEFI.

I have updated my bios to the latest version and that hashas made no difference either.

I can access the ASRock quick flash options for updating the UEFI and the boot device menu (which are part of the UEFI I think) while my graphics card is connected and they work ok just the main interface that requires me to remove my Graphics card and connect directly to motherboards integrated dvi.

I've never had a PC that had UEFI before so my knowledge of UEFI is limited compared to a traditional BIOS. Do you know how I can solve this problem? I've listed my specs below for you

CPU - Intel Core i5 6600 3.3GHz Socket 1151 6MB L3
M/Board - ASRock H170A-X1
RAM - Corsair Vengeance LPX 16GB (2 x 8GB) DDR4 PC4-19200 2400MHz
SSD - Samsung 850 EVO 500GB
GPU - MSI R9 280X 3G (has hybrid bios for both UEFI systems and BIOS systems, currently I have hybrid bios switched on but turning it off makes no difference)

Thanks

I hate UEFI, just do legacy, the machine boots just as fast. If you use UEFI and your windows 10 crashes and you boot off a win10 flash drive, your drive will be locked and unrepairable.

Your motherboard has built-in VGA drivers that seem to be unable to run your graphics card. You have never been able to access the motherboard firmware with graphics card plugged in? What about before you installed Windows?

From my testing so far, I have found that I can get into the UEFI when I use the graphics card but only when I have my monitor connected to the GPU via DVI and not via HDMI. From what I have been able to establish the board triestries to detect the supported resolutions of the card and it can't detect the supported resolution it defaults to 1024x768. In my case that's what it's doing so perhaps the gpu doesn't like outputting at 1024x768 via HDMI or something like that. Either way I'm just gonna leave a spare dvi cable connected to my monitor and plug it into my gpu as and when I need to access the UEFI (which is rarely).

Motherboards generally do not support HDMI natively. And they will not have a selection of resolutions to pick from. I think you found your problem.
