I know this has been touched on by a lot of different threads by a lot of different people, but I can't for the life of me figure out how to fix it.

I'm on a duel boot Windows 8/Ubuntu system and have recently changed my monitor. I am using proprietary drivers and my graphics card is a Nvidia GeForce 660 Ti, the new monitor I am using is a VX2025wm (click here to view the manual).

I know that the monitor works on it's native resolution, because when booting on Windows 8 it automatically adjusts to 1680x1050. I'm not sure if it's worth noting or not, but the old monitor would view GRUB on a higher resolution by default, while this one continues to use low resolution until booted into Windows 8.

I'm really at my wits end, I'm not really used to Ubuntu and I don't have a ton of experience with Linux in general. Any help would be greatly appreciated.

I've included my xorg.conf file

  • What version of the Nvidia driver are you using? Post the output of dkms status. Have you tried installing an experimental one in the "Additional Drivers" system application?

  • nvidia-current-updates, 304.51, 3.5.0-21-generic, x86_64: installed I installed the experimental one last night, and it did nothing to change the problem, so I went back to current-updates.

Working on it all day, I've come to the conclusion that problem lies solely in the monitor, VX2025wm's have a history of problems for the EDID and DVI Input, such as not showing native resolution, Signal Not Found errors, and a bunch of other messy little things that aren't conducive to a fluid computing environment.

The solution lied in adding a Custom EDID to the xorg.conf file:

Option         "CustomEDID" "DFP-0:/etc/X11/viewsonic.raw"

For this specific monitor, I was able to find the EDID here: http://blog.komeil.com/2008/06/fixing-edid-dvi-monitors-no-signal.html

I hope this helps anyone who is having problems with their native resolution and is certain that their Graphics Cards / Drivers are not the problem.
