Actually I've tried many different themes since this problem began -
all standard Microsoft stuff and nothing strange.
Have you tried turning themes off completely?
I looked through the registry entries and other areas on this win 7 32
desktop, which uses AMD video cards. I was totally appalled to find the
extremely large number of entries in the registry and OEM*.inf files
that are associated with the video cards. Occasionally, this desktop
suffers from the same malady that you have. It turns out that updating
video drivers and associated software is the usual cause.
Beyond the usual windows methods of setting video resolution, the AMD
and NVIDIA video cards usually have their own software for doing such
things. (which may or may not be installed on a given system, since it's
usually possible to install just the drivers.)
(Since the system I'm talking about/using happens to be about the
dirtiest system I have in terms of the software, was updated from win 7
Pro "Gold" and exposed on a daily basis to just about everything one
might run into on the web, anything can happen.)
Anyway the NVIDIA video utilities and the built in windows utilities for
doing such things as setting resolution and in my case audio, can have
conflicts. Some of the registry entries are not common, for one thing.
Even though the entries may be for the same purpose.
Just to complicate things further- -
An off the shelf system may have drivers unique to that system.
The drivers are generally a "tweaked" version of the standard drivers.
As time goes on, the OEM may or may not update them. Usually and
eventually, the choice is to change to the "generic" drivers updated by
the video card/chip OEM, or continue to use the older "tweaked" OEM
version. In the past, this was a significant problem with many of the
laptops, and not so much desktops.
What has worked in my case is to reinstall over the existing drivers and
utilities. This usually fixes the video resolution problem, and often
causes audio problems, which I generally cure by manually resetting
audio playback settings. (Video card audio vs motherboard audio and so
One other thing I can think of has to do with the refresh rate.
Typically, LCD monitors capable of 1920x1080 have a refresh rate of
60Hz. The lower resolutions may have a higher refresh rate, say 75Hz.
It may be possible to set the lower resolution that your system goes to
to a 60HZ refresh rate, shutdown, reboot, select 1920x1080 at 60hz, then
shutdown and reboot. An oddity I've found related to video resolution
has to do with resolutions supporting HDTV and "conventional" resolution
settings in the video utilities.
There were conflicts that were dependent on the order the settings were
made in some of the AMD and NVIDIA utilities.
