ASUS EFI Problems

Hello,
I'm using an ASUS P8Z68-V Pro + an ASUS EAH6970 DCII/2DI4S/2GD5 + a Belinea 10 30 40 CRT monitor (VGA with a DVI adapter). Lastly Windows 7 64bit.

Now my problem:
My EFI is completely screwed up. I can't see the entire screen and I'm also getting weird artifacts but this is only in the "bios". In Windows, everything is fine.

Some pictures (these are not resized, this is the maximum that I can see):

It is your DVI to VGA Adapter.

On some lower resolutions and color settings those don't work right.

Once the OS boots up, and loads the drivers for the GPU it starts working properly, but BIOS is pre drivers.

Is there anything I can do about that besides buying a LCD Monitor ?

This is going to sound a little weird but bear with me...

If you look at the back of your computer (unless you have the MB mounted upside down.) your adapter should be in the DVI Slot on the right, or the one that is further away from the MB, closer to the case door.

Yep, that's where the VGA->DVI port is. The other one only supports DVI/HDMI.
It has been in there since I assembled the PC.

Exactly what I was double-checking. :D 

Is this a new problem, or has it always been there?
September 28, 2011 9:27:25 PM

Never been there. I created this PC just a few days. I had a MSI P45 DDR2 Socket 775 with a Radeon HD4870 512MB.
Maybe try and put the 4870 back in the PC and remove the 6970 to see if EFI is still broken ?

The problem is not with the UEFI itself just the graphics driver.

Try putting the 4870 in and changing the settings you want to change (if you can see it properly) then when you get it all together, just switch back to the 6970

The other thing you can try doing is updating the BIOS, maybe there is a fix inside of a new BIOS revision.

Updated to 0706 (should be the latest), no change.
