Hey all,

I recently just upgraded my monitor to an Ultrawide Monitor. It's the LG 29UM67, which has a resolution of 2560x1080. The monitor works beautifully inside the Windows 10 OS, however while booting up it does not. Now, I can't take a screenshot of my PC booting up, so I'll do my best to describe what's going on.

Whenever I boot up my PC, everything looks distorted. The ASUS Logo (I have and Asus A88XM-A) and the Windows logo are completely distorted and flickering. It continues to act up until I reach the Windows login screen, which leads me to believe that my Graphics Driver (AMD Crimson 16.1) is taking over once I reach the login screen. I'm clueless as to how I should go about fixing it. I obviously can't have AMD's drivers load up during the initial POST and boot sequence, so I'm unable to fix the extreme distortion.

The real problem is the BIOS.. The text is unreadable & stretched out, and it flickers constantly. Now, I'm a tweaker which means I go into the BIOS a fair amount. Not being able to use the BIOS is a big problem. If I'm able to, I could try and take a picture of the BIOS with my phone, but I don't think it'll do much.

Help would be much appreciated.

Mobo: Asus A88XM-A
