I've also run into this problem, but only one some machines. On our P4 machines (845 chipset, onboard Intel extreme graphics, etc) I get prompted to install the plug & play monitor. On our P3 machines (815 chipset, onboard video) I get no prompt. Both machines are being run through a kvm, so there is absolutely no difference in monitor hardware that woudl be causing this. The P3's video drivers are included with XP, but the P4's video had to be added to the cd. It appears that the non-cd video drivers may be causing this? Are other people having this if they include their own video drivers?
