Hi, I have a GTX770 which works great, but when using my motherboard HDMI as output there is no output until the windows log in screen. It doesn't show the BIOS or starting Windows, it just displays the Windows log on and after that. When I access the BIOS the display will never have any output. Any help with this would be great, thanks.
 
Solution
Its been awhile since I have been inside a intel system bios but you should be able to disable IGU in the bios and use discreet card in bios.

Yeah sure:
Intel Core i7-4770K 3.5GHz Quad-Core Processor
Gigabyte GA-Z87X-UD3H ATX LGA1150 Motherboard
Asus GeForce GTX 770 2GB Video Card
Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory
Sandisk Ultra Plus 128GB 2.5" Solid State Disk
Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive

If I think you mean what I think you do: I don't want to disable it I want to be able to use both because currently I can't use my GTX for an alternate boot (don't have the drivers yet), so I need to use my mbo HDMI for it, but I can't access the boot options whilst using the mbo HDMI because it only starts working at Windows so I can't get into my other boot.

I disabled Intel Graphics like you suggested and now, although I can't use the mbo HDMI, for some reason now that they are disabled the GTX770 works with Ubuntu whereas before it didn't? I thought it was a driver issue, obviously not. So thanks for solving that for me, any idea why disabling the Intel Graphics would make the GTX work even though I was using the HDMI from the graphics card initially?
