This is so odd that i don't even know how to start searching the internet for answers. I'm hoping someone here can help us out.
I have a single computer running windows xp (all latest service packs and updates) with multiple user accounts (for home use). 2 accounts are Administrator Accounts, and 2 are Limited Accounts (not sure if this is important or not). We have an ATI All-in-Wonder 9600 series video card and a Samsung LCD monitor.
I have noticed that still image splash screens that often show up in video games look crappy on both of the Admin accounts, but look great on the Limited accounts. Attached is an example ("my logon" refers to an admin account, "mackenzie's logon" refers to a limited account).
I have tried creating new limited and administrator accounts, but the image quality is poor for both. In reviewing the Display Settings, everything seems to be the same (resolution, refresh rate, monitor type... etc.) for all accounts on the computer.
I once went into the registry to make it so that none of the Limited Users can turn off the computer. Final thing i can recall doing is blocking all "questionable" web sites for Limited Users through my antivirus software (Kaspersky 7). These are the only things (that i can recall) that differ between the admin and limited accounts.
Any ideas of possible reasons for the difference in image quality would be greatly apprecaited.
