I have a Dell C840 notebook computer and am having some strange issues
with colour depth when I change the screen resolution.
Firstly I have a desktop wallpaper which has graduated fill over a
large area and this is how why I first noticed the problem.
When I setup my desktop initially, I set the screen resolution to
1600 x 1200.
If I change the screen resolution to anything less, the apparent
colour depth of the display drops dramitcally, even though Display
settings still reports a colour depth of 32 bits. Changing the
resolution back to 1600 x 1200 does not reverse the problem. Only if I
log off and then long back in will the issue be resolved.
How can I tell the colour depth has dropped, simply because my nice
smooth graduated background now consists of ugly concentric circles.
The problem is not just related to the wallpaper, but any image with a
graduation in colour shows distinct stripes.
Please note, this problems only appears to occur when I am logged into
the machine in a non-administrative account. So my guess as the what
the cause of the problem is would be that certain registry settings
don't have the correct permissions to be modified by non-admins.
Can anyone shed any light on this issue.
Help much appreciated.
