I'm afraid that's not correct. Service Pack 3 doesn't care whether you
have an analog (VGA) or a digital (DVI) connection to your monitor. I'm
use a DVI connection with SP 3 - no trouble.

my PC and put it on their bench.

It was the video cable. For some reason, XP SP 1 would use the DVI video
cable but SP 3 required the VGA cable.

Thank you for your help
