That is what we use here. Both CAD stations have these.
I don't know what the correct term for it is, but there is a little "ghosting" while rotating parts. Since this is my first experience with an LCD, I can't say if it is a bad thing, or a good thing. I do know that it does not effect my ability or speed of work. The only problem that I ran into was that since I had a good video card (Quadro 1300) and this new HUGE monitor, I thought it would be kool to crank the resolution to the max (2048 x 1536). Display was great at that resolution. However I had a hard time selecting things on the screen such as edges and vertices and such. I ended up making my own custom resolution at 1480 x 1110 to get the correct aspect ratio. This was a happy-medium resolution between quality and the ability to select things. Your experience may vary as I have never been known as a fast clicker like some.
Overall I would recommend this huge monitor.
