Z77-D3H won't boot using graphics card, always uses iGPU

[David164v8]

Even whenever the motherboards display outputs aren't connected to the TV, it still decides to use the iGPU over my graphics card! I can't use my computer now, unless I plug in my motherboard to my TV. This is really irritating, as this PC was intended for gaming :/

I have went into the BIOS and set Display output to PEG (PCI-Express 16x according to the manual, which is what my 6870 is plugged into), but whenever I click on "Save and exit" the computer reboots and it still uses the iGPU. After rebooting, if I check the BIOS again, the setting has been changed from "PEG" to "auto"

I have considered updating from F11 to F18, but thought I would check here to see if anyone has had this problem. Overall I am very disappointed with this motherboards BIOS, I also had the BIOS bug that made my computer lockup randomly (fixed by setting BLCK to 100.1).

According to the manual, "PCI" refers to the normal PCI slot, not PCI-E. I was thinking about the Beta BIOS, but I didn't want to try anything too risky. I have the F18 bios ready to go however.

im not using my gigabyte board atm so i cant check,but pretty sure mines left on auto,im using a 5770 and tested with a 7850,it detects both cards fine,could try reinstalling the graphic card afew times if the newer bios doesnt cure it

Yes if first display device is set to AUTO and you have a GPU installed it should default to the GPU even if you are connected to the IGPU.

I would suggest doing a clear cmos and loading optimized defaults first then, suggest updating the latest bios/beta bios. Also you could just disable the igpu and see if that helps.
