$219.99 FS
I may regret this. Amazon reviews claim only 4:2:0 chroma at 4K@60, so in theory, will suck as a PC monitor. Also mention of forced sharpness enhancement, and no way to adjust settings when in 4K mode.
Has HDMI2.0, HDR, local dimming support.
Edit: DEAD already. Still live on ebay, maybe not for long.
Edit: Back in stock on Newegg. Maybe they're trickling out stock over the entire sale period, to make things more "fair". Or maybe they're actively getting shipments in, or shifting stock between their ebay site and their main site.
Edit: 2016-11-23 7PM EST DEAD again.
Edit: Back in stock.
NOTE: This 4K HDTV on ebay, NO RETURNS. Which is kind of weird, since it qualifies for extended holiday return period on their main site.
Cheap! (Maybe for a reason?)

No 1440P for PC users?
Edit: I received my UHD TV. Set it up, no problems. Looks fairly decent, Skyrim looks pretty amazing at 4K. Text web pages like these forums were a bit hard to read, due to the small text size combined with the auto-sharpening filter that you can't turn off while at 4K res. When I bumped my scaling in Windows 10 64-bit up to 125%, things look better. Some of it may be that I still have VSR turned on in my AMD control panel, let me try disabling that.
Edit: Yep, VSR was also applying a (shader-based?) sharpening filter. Now the text is even better.
Edit: Interestingly, the menu screens looked IDENTICAL to my Westinghouse 24" 1080P HDTV that I had been using. I wonder if they are made in the same factory? Or is there some sort of "standard" HDTV OSD OS firmware package, like an AMI BIOS or something, for TVs?
Edit: I put VSR and GPU scaling back on. Then, I selected the highest VSR resolution for the desktop that my RX 460 4GB card apparently supports, 5120x2880. Then, I adjusted the Windows 10 scaling, to 125%.
Edit: A few days into using it, I like it, even with the shortcomings like the forced sharpness enhancement in 4K mode. 125% scale factor in Windows 10 seems to allow the text to be readable.
And, if if I had to guess, I would say that HDR seems like it's working, watching YouTube 4K videos? At least, the 4K fireplace, and 4K Costa Rica nature videos looked really amazing and lifelike. The colors on the nature video really POPPED.
This set is AMAZING to game on or watch videos on. Text is so-so.
I saw the fourth review on Newegg, someone was using a GTX 1070, and thought that the colors weren't very good. I think that his setup, using "limited" color range, and not being set up to use HDR, is the reason. I know that my RX 460 4GB Nitro card DOES support HDR.
Edit: 2016-11-27, I ordered another one from ebay, they dropped the price to $199.99 FS. I guess I felt the need to "double down" on the deal and cost-average downwards. Plus, I really did want two of them, for both PCs. (Almost ordered two initially. Glad I waited on the second one.)
4K is amazing for productivity. It's like having four 1080P monitors hooked up, without the space, power, hassle, outputs, etc.
Edit: After using this TV for a few weeks, I like how it looks with my RX 460 card in Win10 64-bit, and Linux @ 1080P looks OK too, but I just hooked it up to an ITX PC with an i3-6100 using the iGPU over HDMI @ 4K30, and it's less than great. Reading some sites in Firefox, is very difficult. Using Win7 64-bit with some Intel iGPU driver on this box, so no VSR, and probably no HDR. HDMI 1.4, I think.
Also, there seems to be some backlight glow, with a black background screen.
Edit: Hooked up my second one, finally. This rig has a couple of 7950 3GB cards in it. Those cards only support HDMI 1.4 and DP 1.2. So I would need one of those Club3D DP-to-HDMI2.0 active adapters to use these cards @ 4K60. But interestingly enough, at 4K30, the Radeon Settings is showing 4:4:4. No wonder the text is easier to read than my other one, which is running on an RX 460 4GB Nitro card, at 4K60 / 4:2:0 (maybe 4:2:2?).
It is my understanding, that it is a limitation of the HDMI2.0 spec, that you CANNOT do 4:4:4, 4K60, and HDCP2.2, all at the same time. Given that factor, it would be a nice option, if the firmware let us disable HDCP2.2, and use 4:4:4 @ 4K60, for desktop / computer usage.
Also, there are four physical HDMI ports. Which explains why the firmware shows four HDMI inputs. Some of the online sales sites for this TV, list "three HDMI2.0 ports, one MHL port". Which, I think, MHL is backwards-compatible with HDMI, but it may only be 1.4 or 1.3. So this thing only has three 2.0 ports, I think. Which is still plenty.
