not the brightest screen (100Cd/m2), but it says that it is 20 bit.

ive got one of these but i havent had the time to get a controller for it. you might want to check with allenrubble to see if his controllers would work with this screen. there has been some talk by others lately (me included) but nothing has been figured out yet. oh, and these screens usually go really cheap, so it might not be a bad idea to pick one up for the hell of it...thats what i did.
