<pre>Adding/setting a modeline in xrandr for the native resolution at 80hz (instead
of 60hz) works around this problem in X. I noticed my dell monitor was
outputting at 56hz when it should have been at 75hz on a lower resolution.
There seems to be a 3/4 ratio between what the display sees and what xrandr
sees.</pre>
