A friend recently got a super-wide Philips (I think) monitor. It's sweet - you can display two inputs side by side, each at full HD res. Nice for full HD desktop on one side, full HD movie on the other.

It's a pretty pricey monitor, but the cheap fuckers skimped on the processing electronics: if you want to use two inputs at once, one *must* be Display Port, and one *must* be either DVI or HDMI. Despite the thing having about 4 HDMI ports and 2 DVI ports, the cheap bastards only allow one signal processor for 6 inputs :C
