As someone who's been following the price of this TV on Amazon for a while, I can say this isn't a very rare or special price. It's been at $300 mark at least several times over the course of the year.
There's a large thread about it here:
From http://9to5mac.files.wordpress.com/2014/02/tablet-battery-life.jpg, it shows 614 minutes of wifi browsing and 604 minutes of video. That's 10+ hours.
Very intensive games will probably be between 7-10 hours, but that's still long enough to consider "infinite" by my standards. In other...
It's a Retina mini, so 2048x1536.
That's 10+ hours of non stop heavy use, like watching a video over wifi or playing 3D games.

Yeah, it's the same problem as alamone described.

Here's how it looks on my Seiki 39" with Sharpness 0, Noise Reduction "Off":
Here's that same .png on a normal 1080p monitor, for comparison...
I've tried both the latest firmware for 39" and 50", no...
Yep, that's me. :)
Thanks, I just found out how to access the service menu (MENU, 0, 0, 0, 0), and the version info is there. Next up I lowered the backlight brightness, so it's much easier to look from up close now. I've already set sharpness to 0 (made a big improvement), and turned noise...
