Solution for monitor stuck at 1600 x 1200

[Aquila76]

I had some weird error happen with my display, a NEC LCD2690WUXi. Windows and ATI Catalyst were set to 1920x1200, but the monitor would only display 1600 pixels wide, instead of 1920 (see screenshot).

Somehow the display width got forced to 1600 from 1920. Not sure what caused this, and I have never seen this happen in almost 10 years of owning this display. Anyway, I was able to resolve it by booting the monitor into advanced settings (power off, hold input and power), go to Tab 4, and manually set the "H. Resolution" field back to 1920 (see screenshot).

While my solution was specific to my monitor, this might help someone else suffering from the same problem.

How weird. I was going to say your original image doesn't show any horizontal compression, but then I realized it looks to be cropping your input. I can't say I have ever seen anything like that.

Yeah, it was totally bizarre. It basically trimmed 160 pixels on both sides of the image. Not sure what flipped that setting, but at least I figured out how to fix it.

Zoom.

Had a similar issue, when using a single link DVI cable, instead of a dual link one.
