My desktop at work has just been replaced with a Dell Optiplex 390. I have legit local admin rights. It's an i5 quad with 8GB of ram so I can't really complain about anything but I've run into a snag. My old machine was a self build that I ran 3 monitors by simply using the onboard plus a cheap video card. The new machine won't run both a PCI express video card and the internal video at the same time.... at least according to our IT goons. The bios is password protected so I can't verify that but I'd like to avoid that battle for now.

Can anyone suggest a USB video adapter that doesn't suck? This would simply be for a third display to constantly run diagnostic data on. It's about as non graphic intensive as can be and would be low resolution like say a 17" LCD running 1280x1024. I just want clear smooth video, not 3D. I think a USB adapter would be the "less drama" route.

The machine does have an available PCI express slot that's not in use. Is there a low profile (and cheap) video card that will drive 3 monitors? None of them will have display port and I'd rather not pop open their case to do something but it's an option.
 
try to get into the BIOS and see if you can set the video option to IG to always on....

thetre are some intel mobo i know in the 67/77 and that range that wont allow you to do both.. but you could also buy a cheapo i think 5770 that has 3 outputs....
