Comment 6 for bug 48289

Are you still having this problem?

This might be a stupid suggestion, but have you tried using the controls on the monitor for adjusting screen position/zoom/etc.?

I'd run into a very similar issue today with a black strip on the left when I went to a new resolution, but it was just because the monitor was off-centered.

Since you encounter this same issue at this resolution on SuSE, then it's more likely to be the hardware than the software, so I wonder if you're having the same issue?
