Summary: The main application I can currently use it for is the internet game "The Hunter" in which the picture is superb. I am not having mouse lag problems but I use a high end gaming mouse which, so far, seems to negate the complaints I saw from many of the reviewers of the screen on this site. I got the 50" version and use it as a computer monitor.
One Pretty darn nice 4k - AFTER you get your Stuff in order..

Summary: This isn't a TV that you unbox and Love forever.. You need to update the firmware and adjust some settings immediately if you want the best experience.. Then after you do that.. Along with making sure you have upgraded your HDMI cables then you are set.. Go to the Seiki site and do the firmware update.. Then learn how to get into the Service Mode.. - Go into Menu.. Then press "0000" This will bring you into the Service Menu..
Summary: This is by far the best electronic purchase I've made in a few years. I always seem to be just keeping pace with the TV market or trying to play catch up, but this Seiki 4K has allowed me to jump ahead of the time. The picture is stellar after some tweaking and blu ray DVDs look fantastic. Although there is very little 4K content available now, it will soon be the standard for HD, and being prepared early is a smart choice.
Summary: It is really, really Important for people to grasp what 4K is. The Easiest, yet most common form of 4K Content is IMAX Movies. Those are 4K Movies. Hence the Feeling you experience in the theater, is the result of Very High End Sound (22.2 Surround), Complete Light Control, and UHD on the Screen Aka 4K. What this TV does, is provide the Same level of Immersion while using it. I have the 39" 4K as well. This 50" Model is a very noticeable upgrade. Settings much better.
Summary: I ordered this TV last week for 629. Im not sure why the price jumped up so high so quickly, but its a good monitor. I wouldnt use it as a TV though. You need a newer graphics card to run it. My m6600 didnt work right out of the box with ATI M6900. I would recommend if the price goes back down or they add hdmi 2.0.
Summary: So how does this TV perform? If you're buying this as a TV, forget about it, go somewhere else. You want to use this as a computer monitor? Now we're cookin'! Before I go any further: turn the Sharpness down to 0. Just do it. Trust me. 1080p content on this set is terrible. Alright, I'm exaggerating. It's probably what you would expect from other third tier brands like Westinghouse, Emerson, Sanyo, etc. which means it's super mediocre to not very good.
Summary: Assuming you can't wait for a 60Hz version of 4K monitor and you are comparing this to the TCL LE50UHDE5691 50-Inch 4K Ultra HD 120Hz LED TV there are two issues. The first is that as others have noted my TV needed an updated ROM to work correctly. It was a little tricky to update but worked just fine once I found accurate instructions. I'll probably buy a second of these soon now that the price is 1/2 what it was [and I've got the whole flashing of the ROM thing down].
Never even got to turn it on, horrible warranty support

Summary: I haven't even turned this TV on and I'm already disappointed. I took it out of the box, went to assemble the stand, and found that the stand was incorrectly glued together so I can't possibly screw it in as required. In other words, I have a TV that can't stand. It's completely unusable unless I go out and buy a third-party wall mount.
Summary: I bought the 39" version to use as a computer monitor a couple months ago and liked it enough with it that I decided I wanted another. Rather than get another 39-incher, I chose the 50" because I'd read some reviews that suggested it had a better panel and could actually do 120Hz gaming (the 39" drop frames).
Summary: I bought mine from Sears for around $700 last weekend. I am using it as a computer monitor at 3840 x 2160 @ 30Hz with s very old video card GT 430 which is fairly low end. I was surprised to see that old card was able to do 4k resolution after updating the driver. Now thid is a very large desktop, you can fit 6 large windows easily. I was not sure if 39" would be too small text/front for me to read since I don't have good vision, so I went with 50".
