I got a Seiki monitor off of Amazon http://www.amazon.co...0?ie=UTF8&psc=1
It's a 39" monitor for $340 delivered (to the US). The refresh rate is limited to 30Hz at "4K" resolution and I drive it with my Quatro 4000 video card.
So far I really like it. I've fiddled a bit with Windows font sizing and such.
All of my "professional" work is audio-for-video so it's really nice to be able to have the mixer up, with a reasonably sized video window, while having enough space to edit on. It's also nice to have a reasonable number of tracks to be able to see at one time. Oh, and the 5.1 meters show up too.
I'll probably do some massaging of the way the screen is set up as I live with it. The slow refresh doesn't bother me as far as working goes but NTSC video looks very, er, "video" to my eyes on this screen at 30Hz. So I slowed it down even further: 24Hz. There is lag, sure, but the video is prettier.
