Here's the situation. We have a conference room which many different people use to connect to a Dell 7609wu (1920x1200 native) projector. The problem is the room only has a cat 5 cable going to the projector. We have problems getting the higher resolutions to work and the DDC may be the problem as when you go to Cat 5 most extenders do not send the DDC information thus we have syncing problems. I can't change everyone's laptop so I'm looking for the next best answer. (It may be VGA to DVI to Cat5 and back to DVI). Also does any one have software that will disable the DDC so I can test if that is the problem?
