Umm, not sure, Shady, Omar and I (Police also, I think) use the same ASUS monitor. 144 hz, 1 ms, 3d (if you want to use it), 350 CD, dual link, speakers, excellent tilt and position adjustments. Excellent for around $250 (sale price). It's 24", a 27" is a bigger field - I don't know but I'm very happy with mine.
Mine had a problem and I sent it back for a new one, they paid both ways. Despite that, I'm very happy.
