It is insanely heavy and well built (slightly dropped it once, RIP floor).
The panel: it is much much brighter than a regular TV but the kicker is there is no color or contrasts shift no matter how you look at it. I gamed on it for a while and the pixel response time is insanely fast. It is truly an amazing display. Too bad about the resolution though. I'm not using it anymore but I did not throw it away either.
According to your link (and to what I've seen at work) that's not entirlely correct. One of the differences they give:
> Built to run from 16/7 to 24/7 hours per day, have better cooling for longer runtimes
I bet this alone increases the price but quite a hefty amount.
I'm not the GP, but if they're anything like me, they just want the "dumb" part, not the "runs 24/7/365 at blindingly high levels of brightness".
