Public bug reported:

Binary package hint: xorg

After upgrading to Karmic Koala (9.10), my iiyama ProLite E2407HDS
monitor does not display properly at its native resolution of 1920x1080
(16:9). It is auto-detected correctly, but at native res, the screen is
black besides the toolbars, and some apps display when run, but others
do not - for instance Firefox is entirely blank. The display is only
usable at the lower 16:9 resolution of 1280x720. (Background and apps
all display properly in this lower res.)

When scrolling through all possible resolutions, the majority of the resolutions tested did not display properly. I also checked this page:
https://wiki.ubuntu.com/X/Troubleshooting/Resolution
and was unable to solve the problem. In particular, adding kernel parameter modeset=0 did not do anything, so I cannot say whether Karmic is missing a quirk for this monitor or not.

The display worked fine at its native res (1920x1080) in Jaunty
Jackalope.
