Wrong resolution in UEFI setup menu

I'm going on a wild guess that you are using display port or hdmi for connection when you get the 720p res in the BIOS screen. Do you get the same result with a D-DVI connection?

Motherboard: ASRock Z170 Extreme4 Graphics (PCI-E): EVGA GeForce GTX 950 SC GAMING If I use the on-board graphics (that is, if I connect my monitor directly to the motherboard HDMI or DisplayPort port), the UEFI menu is correctly shown full HD (with a resolution of 1920x1080). However, if I connect my PCI-E graphics card to the monitor, the UEFI is shown with a 1080x720 resolution, even if the graphics card supports full HD and so does the monitor. If I boot into any operating system, the resolution gets correctly set to 1080p, but as long as I stay in the UEFI setup menu the resolution stays at 720p. The "Full HD" setting in the UEFI setup is set to "Auto" and not to "Disabled", so I see no reason why the resolution should not automatically be set to full HD. I tried all the ports of my graphics card and I get the same result.  Do you know a way to fix this, or to manually force the full HD resolution? Thanks.

I have heard of this happening sometimes. Also, other mother board manufactures have a full HD resolution in their UEFI's, and they can have this problem too.

When this happens, it can be difficult to fix. There is not a simple, obvious fix for this situation.

What monitor model are you using?

Did you install the driver for your 950 video card yourself? Is it a new driver version?

What OS or version of Windows are you using?

Which UEFI/BIOS version are you using?

How much DRAM memory do you have? What speed is it running at?

Do you have any other cards in the PCIe slots?
