I just converted my computers and monitors over to DVI and I have a KVM switch with DVI and USB for the keyboard and mouse. The keyboard and mouse work fine. I can't see any video until the computer boots into Windows. I can't change the BIOS and I can't do any boot time recovery so this is absolutely unacceptable. I have an IOgear KVM switch and a NVIDIA video cards. one of my computers has a problem with the CD-ROM door opening. I decided to upgrade the video driver and I uninstalled the old one. Now I have no video on that computer. This makes me wonder if were even ready for DVI yet. But all of the new video cards are coming out with it so people must be surviving. I tried bypassing the switch but that didn't solve the problem. A direct video connection to my NEC projector yields the same negative results. I have three computers hooked up to my KVM switch and their video drivers are not more than three weeks old. I'm sure that some of you out there have encountered a similar problem.
