Pros: The Seiki 39" lets me browse the web at 200% and still see the entire page. Movies look great to me and I see details in scenes that I have been unable to see previously. Light weight for the large size. Speakers are good for little speakers.

Cons: None for me.

Overall Review: Being legally blind, this monitor rolled ten or fifteen years off my worn out eyes. Glad that I bought it.

Pros: 3840x2160 resolution. 120Hz @ 1920x1080 Good Color Good Viewing Angles AWESOME CONTRAST Good response time. Low Input lag (at non-4k resolutions)

Cons: 30Hz @ 3840x2160.

Overall Review: If you reflash this display with the 50 inch models firmware it fixes an issue where it will correctly display 120Hz @ 1080p without frame skipping. It also does perfect pixel doubling at 1080p with this firmware mode which is ideal for computer use so its the biggest 120Hz S-MVA panel I am aware of. Contrast ratio is *excellent* and much better than IPS. Colors/viewing angles are almost as good as an IPS display and the extra contrast makes up for this which makes me feel this looks better than most IPS displays. There is almost no latency when scaling at lower resolutions. It has one frame of input lag. This means only ~8ms when running 1920x1080@120Hz. Also putting it down to 1280x720 @240Hz helps decrease this to ~4ms of latency for those who need as little input lag as possible. First person shooters on a 39 inch display at 120Hz is awesome. Most games couldn't hit good frame rates at 4k anyway so just put it at 1080p for games and get the awesome 120Hz smoothness. The 30hz is really not bad for regular desktop use as a monitor (browsing, programming, playing video). Its really only gaming where that is a problem but the 120Hz gives you an excellent alternative for gaming. I think for most serious gamers the responsiveness is more important than resolution anyway and 1080p is still not bad for doing 120Hz gaming. Considering this display has gone as cheap as $400 online it makes it an excellent value and would recommend to many people.

Pros: Extremely sharp 8-megapixel picture. Have not noticed any dead pixels.

Cons: [1] The default sharpness setting of 50 makes the picture awful; I am fortunate to have set this up in the office before the customer saw it as the default would ruin one's first impression of this TV. It seems the Seiki "sharpness" setting is actually an edge enhancement image processing filter. Once the sharpness is set to zero to disable it, the image is great and appears exactly as received from the video source. [2] The TV would shut off automatically every 4 hours despite having live video on screen. Had to enter the hidden service menu to set the "4Hours auto standby" setting to "Off". This is a separate setting from the sleep timer. [3] The backlight control slider always shows as 100 after a power cycle, even after having been reduced to 75, for example. Since the backlight *will remain* at your chosen setting while the slider still shows 100, any new adjustment will actually cause the image to *brighten* upon the first click down to 99 from the falsely displayed "100". [4] The image has a slight bluish cast, but is easily correctable through color settings in the menus. [5] The built-in scaler does a poor job displaying 1080P. Instead of pixel doubling to keep sharp edges, the picture appears soft and anti-aliased. Possibly OK for games or video, but terrible for PC text or vector graphics. [6] The 30Hz refresh and very slight lag at 4K resolution may make this display inappropriate for gaming (though it is fine for video or general PC use).

Overall Review: I am using this TV with an Intel NUC D54250WYK1 miniature PC also purchased from Newegg Business. Intel says the NUC does not officially support 4K over HDMI because it lacks active level shifters but their internal testing found that it works with a Seiki 4K 50" TV. In my testing with a mini-HDMI to HDMI cable, the picture was fine but dropped out every now and then, but was perfect with an Accell B086B-008B mini-DisplayPort to HDMI 1.4 adapter that I purchased elsewhere. My TV shipped with firmware dated 2013-08-26 but I updated to latest firmware dated 2013-08-28 as found on Seiki's firmware support page to get the backlight control on the main menu and fix the 4-hour auto standby. The new firmware also provided a few additional color options on the main menu. After inserting the configured USB drive, the firmware update did not happen automatically after a power cycle as Seiki's web site said it would. I had to enter the hidden service menu to initiate it. Some say entering the service menu may affect the warranty, but I found it necessary to update the firmware to correct a couple shortcomings with this TV. I will be buying more of these and the Intel NUC for use with our IP CCTV cameras.

Pros: I absolutely love this TV. Everything about it has made me happy. It actually exceeded my expectations. And for the price I cannot be happier. The 4k video mode is precisely as crisp as my original 22" computer LCD screen. I was not expecting it to look this well as I have used hi-def TV's as monitors before but this is the first one that actually has the quality of a regular computer screen. It feels like I have the desktop real estate of approximately four computer monitors but without any seams. As a programmer, the extra space is useful as I can layout all of my files at once without overlap and doing so assists greatly with productivity. When I finally located a true 4k video that matched the resolution of the screen I was literally blown out of my chair and across the room by the stunning quality.

Cons: In 1080p this monitor is blazing fast and most media is already in 1080p so as expected it looks incredible. Gaming is smooth and very responsive. You will notice the upscaling because unlike on a 1080p screen there are more pixels in there so the artifacts do exist, sit a few feet back and you can't see them at all. Better than any HD TV I've ever seen. In 4k resolution everything is crisp and beautiful, however 30hz may affect your decision. It certainly won't get in your way and personally I don't mind it when I'm gaming. However, if you are an elitist screen aficionado then you probably cringe at anything under 120hz, this monitor will probably make you want to give up your first born child. However, if you can't really tell the difference between 55hz 60hz 65hz 75hz or 120hz then do not fear the 30hz rate you will get used to it very fast as it is not really that noticeable if you are doing work and not actively analyzing the refresh rate under a microscope. The most noticeable disadvantage I've had so far is the desktop is so big it takes a couple flicks to get my mouse across the screen even on high sensitivity. This monitor is excellent and for the price it cannot be beat.

Overall Review: No regrets! Quality and surprisingly useful. Make sure your video card can handle the screen resolution. I upgraded to a GTX 760.

Pros: -Got this on Black Friday special for $209 shipped to my door after Visa Checkout. Absolute steal for 4K picture<br>-Does 1080p gaming at 120Hz with a few adjustments in Radeon settings<br>-Factory 39 inch firmware has been updated. True 120Hz support enabled out of the box for 1080p. No update required.<br>-Youtube and Civilization V in 4K are amazing. Strategy games play okay IMO at 30 FPS.<br>-The set I received has no dead pixels

Cons: -No HDCP 2.2 means no Netflix in 4K. At least not yet. (Hopefully this will be resolved when Netflix brings 4K to browser streaming)<br>-Screws took an amazing amount of effort to insert. Holes were probably not threaded. Make sure you have someone physically fit to assemble this. I'm serious, unless you're going to wall mount it. <br>-Some input lag at 4K. But nothing that can't be compensated for with higher sensitivity settings and a good DPI mouse. <br>-Not good for people who want to play games at 4K (except strategy) or are not tech savvy. If the idea of messing with menu settings, factory settings or updating the firmware scares you, this set is probably not for you.<br>-Colors are pretty washed, especially on lower (non-native) resolutions.

Overall Review: So much on the web about the Seiki, I was a little worried however this set is a solid contender for an entry-level 4K TV and combined with its price point on Black Friday, really makes a strong push for the top of the best bang for your buck TV category. <br>Now, with that said, this is NOT a 4K on par with most any other set out there and you should have some tech knowledge going in, especially if you want to use 1080p at 120Hz. <br><br>I got this because I was considering it and a 1080p TV at the same price point on Black Friday. The final decision maker was the 120Hz @ 1080p. Most economy 1080p sets will only display 1080p @ 60Hz. So I figured I could get the benefits of 4K for desktop work and game at 120Hz in 1080p. <br><br>I had to play around with the custom resolutions in Radeon to get 120Hz @ 1080p. Make sure display scaling is disabled or the GPU will automatically upscale 1080p to a 4K picture (and signal) which will display as 4K on your monitor. Hit "display" on your remote to check the input signal level and refresh rate.<br><br>Some input lag is there on 4K as others have said, but I think more of it is due to the fact that this is most people's first 4K set and they aren't used to having to move the mouse over the equivalent of 4 1080p individual screen spaces. Increased mouse sensitivity under windows and a high DPI mouse does wonders. It was by no means a deal breaker for me. <br><br>I had the random black screen issues at first maxing out 120Hz at 1080p. Lowering the refresh rate to 110Hz resolved the issue. Im guessing the internal board for this TV is slightly underpowered for this rated specifications. Lower the refresh rate if you're having black screen issues. Also note, the complete turning off and restarting of the TV is a BACKLIGHT issue that was resolved with the firmware update. <br><br>Colors are definitely washed, especially at lower resolutions. But not too bad and the 4K picture definitely pops. 1080 picture quality fell into the "acceptable" range, IMO. But not any worse than my first 1080i TV. And again - 120Hz refresh rate gets this TV the nod over regular 1080 TVs.<br><br>All in all - this TV was an absolute killer deal as long as the set lasts a few years and you know what you are getting. You are NOT getting a 4K gaming set, nor are you getting an highly color accurate set. What you ARE getting is 4K workspace and videos at a currently 1080p price and the option to game at 1080p at 120 FPS. As long as you don't have needs outside the intended audience, then this should serve as a great entry to 4K. <br><br>Test System:<br>i3-4160 Dual Core<br>8GB DDR3 1600 RAM<br>AMD Gigabyte R9 270 OC'd to 1050MHz Core Clock/1500MHz Memory<br>ASRock Extreme6 Z97 Motherboard<br>EVGA 1050GS Power Supply<br>Logitech G100 Basic Gaming Mouse UPDATE 1/11/2016: The new update from Windows 10 REALLY helps this TV. Im referencing the one that restarts your computer several times and installs on a black screen. 120Hz detection on modded firmware no problem on all games

Pros: Running 3 of these (separately), one off a 2013 macbook pro retina (15") via HDMI at 4k resolution (I didnt think the HDMI would suffice but I was wrong), image quality is AWESOME, and the price (I paid $500 on sale) was unbelievable. The other two are running off of GTX 760's on hackintosh systems, works flawlessly.

Cons: One display came without any HDMI cable, no screws to attach the stand and no instructions or remotes. I'm sure this was not a normal scenario, but still...not good to not have a decent quality control team ensuring things like this doesn't happen. Imagine if this order was sent to Hawaii, the poor guy would have to ship it back, wait another few weeks in order to get another. I'd be livid.

Overall Review: Overall it's awesome. I have a couple graphic designers working with them, the color is superb and our video editor loves that he can edit RAW RED Epic footage in it's native 4k resolution.

Pros: Cost, Cost, Cost! Very good value. 4k desktop looks awesome! But don't just think you can run this at 4K in games. You will need a very good Video card with 3 to 4 gig mem to even come close. Using Crossfire - SLI you can game at 4K, but you might see a little framing due to 30 HZ. The REAL win is 2560 X 1440 at 60 HZ, it is awesome, and most V cards have no problems with it. You might need to add the 2560 X 1440 info to your V card resolution list.

Cons: Having to hit the on button on remote. No auto on feature.

Overall Review: USB 2.0 Needed!

Pros: * Great picture at 4k * Almost all firmware issues from 2013/2014 appear to be resolved * No issues getting 4k working on different PCs * Gaming working okay at 4k on older hardware I wasn't expecting things to go as smooth as they did with this TV as a PC monitor. Didn't need to do any firmware updates, etc. as mentioned in older reviews from 2013/2014. I think every option except maybe turning off the 4 hour shutoff is now available in the main menu. Menu-0000 will get into the service menu to turn that off. For just about every manufacturer (AMD/ATI, nVidia, Intel), you need to run a utility to unlock the pixel clock on the HDMI port or use an active displayport to HDMI converter to get 4k to work from a DP output port. I ran the ATI pixel unlock utility to get 4k@30Hz working, and ran the special Intel custom resolution utility to get an Intel 4000 based laptop working at 4K@24Hz. Ran both over an HDMI output port with either an HDMI 1.4 or 2.0 cable (only 1.4 i s needed) into one of the TV HDMI ports (both 1 and 3 seem to work fine, never tried 2 as it doesn't have enough space for most cables to get in). Picture is good, I made minor adjustments to taste. I did a stuck on/off pixel check and did find 4 individual pixels stuck off, none stuck on, but the pixels are so small unless multiple are stuck together (mine weren't) it's very difficult to notice. I had about a dozen cases I thought were bad pixels that ended up just being dust. I haven't "renoticed" them in 2 weeks of PC use and games - that hasn't been the case with other TVs and monitors that had a stuck pixel for me in the past. Does 4k@30Hz on a PC very well. Runs fine with both Intel 4000 onboard graphics and 2010-era AMD/ATI 5770 card. I was running Skyrim at about 16 FPS, XCOM and Shadow of Mordor at about 20. Skyrim had bad mouse lag at that rate, but XCOM and SOM have none. I know these are not exactly state of the art games in the graphics requirements, even at high/ultra settings, but I'm running them at 4k on mediocre 2010 hardware, so I'm happy. It will run at 1080p@120Hz, but you need to mess with custom resolution settings (check out CRU utility). With CRU you can set up intermediate screens as well if your gaming rig can handle higher refreshes (1440p@66, 1800p@40, or whatever they end up being, etc.).

Cons: * 30 Hz limit at 4k - though this works fine for me! * a few dead pixels, not that I notice * Good enough speakers for basic tasks, but this isn't a built in sound system... * No PC power-saving mode built in for monitor mode * Will not accept any audio input other than HDMI when using that as a video input. I had a problem with my HDMI audio driver (ATI/AMD had an issue a few years ago, still had the bad drivers on my PC, just needed to upgrade the driver to clear it up though). Even with the firmware seeming to be okay now, this is not 100% user friendly. If you are uncomfortable with electronics, probably want to pass by this one by. There are enough reports of these sets dying in under a year to make me a bit nervous. I'm hoping these were infancy issues in manufacturing the electronics that have now been resolved, but I'm hanging onto my box in case I need to ship it out for warrantee service...

Overall Review: Note: I'm not using this for color correct work, and haven't tried calibrating it. Download some 4k screenshots (google was a good source for me) and find 20-30 or so good ones and set your background to cycle through them, and/or have the screensaver set to slideshow with them. Find some shots with good clarity and fine details. That's the best way to show this display off, beyond having huge spreadsheets and multiple webpages and documents all open at the same time without needing to overlap them... Likely will need to bump up your mouse speed and/or acceleration when using this. For settings to put in after setting this up - turn sharpness to 0 and noise reduction off in the main menu. Go into the service menu (menu-0000) and turn off the 4 hr timer (I think you need to scroll down off the first page under "other" to find it, if I remember right). The color seemed fine, just adjusted brightness, contrast, etc. to my taste. You can also adjust the backlight - I think the main menu, but might have to find it in the service menu as well (everything in that menu, go to the "other" option at the bottom). This is a great display so far. If it lasts a few years I'll be plenty happy with it given the cost. Five stars as is, because I feel the few issues with the display as it is are easily outweighed by the cost of the display, but I am anxious to see if it can last a good 5 years or more.
