I don't think these are ultrasharps. The one on the right is a newer cheap-o model and quite frankly is pretty rubbish compared to the macbook and the one on the left. The one on the left is an E228WFP and I doubt it's a fancy panel or anything but it's better than the newer one. I use synergy+ to control the laptop and the desktop with one keyboard/mouse between Ubuntu and Windows 7. I don't think I need more than one monitor really but it's just what's available.
