Hello, ive recently upgraded to a new Gaming PC, all brand new components. Heres my spec list

M5A99X Evo R2.0
Corsair 600w Bronze PSU
G.Skill F3-14900CL9-4GBXL (8gb total - DIMM A2/B2 Populated)
AMD Radeon R9 270X
40" Finlux LED HDTV (i dont have any computer moniters)

The computer works flawlessly, although im having a weird screen glitches in the UEFI Bios.
When i enter the BIOS, EZ Mode screen appears but half the screen is black with the date showing at the top, when i wiggle my mouse around the screen pixels start to appear but i cant click on anything.

I then enter advanced mode, to which i can use my keyboard to change the settings but its so hard to see what im changing.

i have an older Nvidia GeFore 8800GTS which i stuck in and booted to bios. everything works fine but the resolution doesnt fit the screen correctly.

So my conclusion is that this motherboard isnt so compatible in the bios with my R9 270X

I have also tried reflashing the bios to an older version (came shipped with latest) with no results.

Im wondering if there is any solution to this?
Thanks

Maybe I missed it but I don't see what CPU you are using? Is it on THIS COMPATIBILITY LIST?

Never seen this before. So, to sum things up so far... The 270X works fine once in Windows, it's only in the UEFI this happens? Also, the 8800GT shows UEFI fine, but the resolution isn't correct/screen cut off somewhat? I know ASUS' UEFI runs at 1024 x 768. It could just be the combination of both cards and your TV don't like such a low resolution.

yeah its only in the bios, the boot logo appears fine on start up (does seem very large on the screen like you said its running at 1024 x 768)
