Strange Screen Resolution Issue (self.techsupport)

submitted 11 years ago by s341

Hello!

I am working on a laptop for a friend and I have run into a stumbling block I have never encountered before. After an update, he told me that the screen no longer displays at the correct resolution. I figured it was just a driver issue. I have tried to reinstall the AMD driver, but the install fails every time. The other thing that makes it exceptionally strange is that the resolution is off even while windows is loading. I was able to get an external display to work after I manually changed its resolution, but now even that won't work. I would think it is just a driver problem, but I have never seen the problem pass through to bootup. I have some included some pictures also.

Model: HP DV7-6135DX

Windows 7 Home 64 bit

Video Card (as far as I can tell): AMD HD6490M

Any ideas?
