Mitsubishi (or NEC for that matter) present good quality screens for PC use, and I even have 4 of them (2x Dual Screen). The only negative aspect about the ones I have in the office is their rather low brightness levels, but that’s ok. Now, Mitsubishi presents 2 sets of 17 and 19″ screens (difference in colour and Xblack or not) with a refresh speed of 2ms and 400cd/m2 for the Xblack versions (300cd/m2 for the “normal” versions). You also get a 1000:1 contrast ratio and a 1280×1024 resolution (at best).
