High end monitor, lightly used. I bought this about two years ago. Unfortunately, I have to sell it because I'm moving out of the country. See below for the spec:

Colors 1.07 billion colors (30 bits)
Brightness 370 nits typical
Contrast Ratio 1000:1 normal, 3000:1 (dynamic)
Video Inputs DVI-D, DisplayPort (both with HDCP)
Viewable Size 29.7" Diagonal
Limited Warranty 3 years parts, labor, and onsite service

The monitor is the one on the right in the picture.

(I'm also selling a speaker system if you are interested.)
