Okay, I'm looking for some suggestions.

Currently, I have two computers and a Dell 30" monitor. Unfortunately, the monitor only has one input (I really wish they'd put at least one more in there). Up until now, I've been moving the cable between the computers, but this is getting really old really fast.

Without thinking it through, I ordered an inexpensive HDMI switch from Monoprice, along with three DVI-HDMI cables. This would have worked great, but the switch can only handle resolutions up to 1080p.

Does anyone have any creative ideas for how I could control both machines without having to a) keep moving that cable back and forth, or b) spending hundreds of dollars on a 2560x1600-capable switch?
