7750 and UEFI not compatible?

[quickshot89]

So trying to install a sapphire 7750 on a HP P6-2494. Disabled the secure boot but i still cant get any output. Onboard output working fine with the 7750 installed.

Any clues?

How are you connecting it all? Via gfx DVI port or the mobo?

I'd personally disable onboard GFX and simply run through gfx card if not already doing it that way.

gfx dvi port when attempting to use it. Checked the bios for an option to disable the onboard but no option there. HP has really limited the options
