Monitor madness 
9th-Sep-2009 04:56 pm
I've got two monitors connected to my PC (and have had for a couple of years); one is a Dell E193FP, the other is a Samsung SyncMaster 2253BW. I have the Samsung as the primary monitor, connected via a KVM; the Dell is connected directly; they're both plugged in to an ATI Sapphire Radeon HD 3650 dual-head video card.

With the Samsung connected to one port (of the ATI card), it gets no/minimal green input; if I swap it to the other port (no change in cables), colour is fine. Plugging the Dell into either port, the colour is fine.

That suggests to me there's a problem with that particular combination of the Samsung monitor, cable and port on the video card. If it was the monitor or the cable, I'd see the same problem when it was connected to the other port. If it was the video card or port, then I'd expect to see the same problem when I plug the Dell monitor into that port.

Could it be there's a very specific problem with that combination?
