Monitor List
In reply to Bob Collette, Oct 4, 2011

Here's a recent post where I've listed monitors but also commented on the 6bit + AFRC versus 8bit issue....

The viewing angle issue....

Here's a list from another thread. I've put pricing in $CAD as that is whet I've seen recently. I'd expect similar in the USA but perhaps with the use of coupons.

HP has just announced a new revision of their ZR monitors, the ZRXX40 series- I'm still reading up on them but it includes a shift from CCFL back lights to W-LED back lights and new sizes such as a 20" 1600x900 8bit model, and a 27" 2560x1440 with an 8bit panel and a 10bit LUT (i.e. can display 16.7 million colors from a palette about 1.04 billion colors).
