Interesting idea. Any recommendations?

A 46" display, for $769, 1080p and 3 x HDMI inputs and all of the necessary sound inputs and outputs. Additionally it's relatively low-power and doesn't actually look bad.
I can see me buying something like this in future, it fits with how I use TV anyway, feeding HDMI inputs into it and just considering it a display for other devices.
I have one of NEC's 24" monitors (one of the few 1920x1200 panels I could find on the shelf at the time I bought it - 16:10 FTW), and I love it. Aside from my preferred 16:10, the other thing I love about it is that it's matte instead of glossy. Glossy monitors, along with chiclet keyboards, have got to go.
