I have a 21" Dell Ul;trascan monitor which recently leaving 'shadows' or 'stains' on screen. I called our IT guys to check it out and they pronounced it past it's sell by date. They just delivered me a new one this morning - this time it's a Samsung SyncMaster 1100DF. I got it all set up and guess what - yep, same problem.....
Any ideas what could be wrong? Could it be the PC causing the problem?
I sit quite close to power supply cabinet. Might that be the cause of the problem?
Thanks in advance for your help,
