Seiki 39" Class 4K Ultra HD 120Hz LED TV

Contrary to popular belief, the ultimate television experience is well within reach. By creating a 4K UHD TV with great picture and sound, minus the unnecessary bells and whistles, we're able to offer you an Ultra HD TV that is ultra affordable.


Seiki Class 4K


Remember how excited you were the first time you saw HD? Multiply that by four and you'll understand 4K Ultra HD from Seiki. With over 8 million individual pixels (3,840 x 2,160) compared to about 2 million (1,920 x 1,080) on your current HDTV, the picture provides stunning clarity and colors that far surpass anything you've seen before. Put simply, you have to see it to believe it.

Seiki Class 4K


With Ultra HD, you'll be able to enjoy your favorite shows and movies in the best resolution possible – whether it's SD or HD, DVD or Blu-Ray. And as more and more 4K content becomes available in the near future, you'll be one of the first to see it in its full Ultra HD glory (via HDMI 1.4 and up to 30Hz)

Seiki Class 4K


The most affordable, highest resolution screen on the market brings new possibilities to the table – not to mention your computer desk. The same promise of detail and clarity that Seiki's 4K brings to your favorite shows, movies, and sports will also be delivered to your workstation, and your online and gaming experience.

Seiki Class 4K


At Seiki, we offer a full line of HD TVs. And UHD will be no different— 50-inch 4K is just the beginning. Look for the generously-sized 65-inch and monitor-friendly 39-inch UHD models in the near future.

5 out of 5 eggs4K For a Fair Price

Pros: Nice display
Tunes channels well
Good VESA mounitng
Good Price

Cons: Input allows for close wall mounting but it is hard to attach cords

Other Thoughts: I use this for a normal TV at 1080P 120HZ so as far as 4K goes I will wait until it becomes the standard.
It is a great TV so far and I enjoy the nice picture.
Will review again if there are any problems.
I have had this for 3 months.

3 out of 5 eggsSeiki SE39UY04 39", 4K, 120Hz LED-LCD HDTV

Pros: Low price for 4K TV
OK Picture
Quick reply from tech support on questions

Cons: Makes a "Poping" sound when turning on - Tech support was no help, said they would pass problem to engineering and get back to me later.
Only recieved 13 channels on cable system - Tech support was no help, said I did not have a QMA tuner - Found answer online in AVS forms firmware upgrade that opened the QMA tuner with password number - Now I have over 100 channels.

4 out of 5 eggsSeiki SE39UY04 39", 4K, 120Hz LED-LCD HDTV - Good HDTV for the Price.

Pros: - Free Delivery
- Not Damaged In Shipping.
- Low cost for a 4K HDTV

Cons: - Another On-Line Competitor (named after an animal) put this exact model on sale for US$10 less the day after I ordered this Seiki HDTV.

Other Thoughts: I ordered this Seiki HDTV for my Mother-In-Law as a late Christmas Present. Newegg was running a sale for US$249 including free shipping so I could get it to the In-Laws without actually having to travel to deliver the HDTV. Newegg and the delivery service made a rural delivery on-time and without damage to the unit. Thank-you Newegg.

My Nephew unboxed and set-up the Seiki HDTV for my In-Laws. They were all highly impressed by the picture quality. The only concern they had was that the color balance was way off. I had to go on-line and research how to adjust the settings then talk them through the adjustments on the HDTV. Documentation that comes with the HDTV is poor. I took one egg off for this.

I cannot speak to the video or audio quality of the unit since I have not seen it myself yet. My Mother-In-Law told me that she wished I had gotten this for her years ago. I didn't bother to tell her that this model wasn't available years ago. My In-Laws are not critical and discerning observers. This HDTV more than met their needs. If this HDTV does not fail in the next 2 years, I will consider it a big win for me.

If you are looking for an inexpensive HDTV in this size range, consider purchasing this Seiki.

5 out of 5 eggsUnbelievable for the price

Pros: The display looks good out of the box. I only use the TV for my PS4 so I only worry about it displaying images at 1080p. The stand it comes with is very sturdy as well.

Cons: Like everyone has said, the remote is a little big.

4 out of 5 eggs4K at $209. Amazing Value, As Long as you know what you are getting

Pros: -Got this on Black Friday special for $209 shipped to my door after Visa Checkout. Absolute steal for 4K picture
-Does 1080p gaming at 120Hz with a few adjustments in Radeon settings
-Factory 39 inch firmware has been updated. True 120Hz support enabled out of the box for 1080p. No update required.
-Youtube and Civilization V in 4K are amazing. Strategy games play okay IMO at 30 FPS.
-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)
-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.
-Some input lag at 4K. But nothing that can't be compensated for with higher sensitivity settings and a good DPI mouse.
-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.
-Colors are pretty washed, especially on lower (non-native) resolutions.

Other Thoughts: 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.
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.

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.

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.

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.

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.

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.

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.

Test System:
i3-4160 Dual Core
8GB DDR3 1600 RAM
AMD Gigabyte R9 270 OC'd to 1050MHz Core Clock/1500MHz Memory
ASRock Extreme6 Z97 Motherboard
EVGA 1050GS Power Supply
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

1 out of 5 eggsZero Response for RMA Request

Pros: Pixel to price ration is nice for an external display. Be prepared to do your own research to find firmware and menu access codes to be able to configure settings that you aren't given easy access to adjust.

Cons: TV arrived with a significant forward angle lean after attaching the stand. Upon further examination, the bezel along the LCD was warped and bubbling out in some areas, and the display itself wasn't just leaning forward, it was bent and curving forward too. Submitted an RMA request, never heard back.

TV itself still functions more or less, but the already not very impressive viewing angle certainly wasn't given any help by the lean and bend. I gave up hope after attempting to email & call Seiki with no response, so I took the plastic casing off of TV to see if I could easily see what was wrong.

The metal at the base of the TV (the piece that attaches the frame to the stand and the pieces that attach the speakers to the frame) was clearly bent, presumably from being dropped _before_ being packaged and shipped. Awesome.

Speakers make a loud strange popping sound every single time the TV is turned on. I suspect this may be related to the damage (as I haven't seen any other mention of this behavior), but it doesn't seem to impact their mediocre sound quality, so that may not be abnormal.

Other Thoughts: If you're reading this review and you're not sure if you want to buy this TV or not - you don't.

If you're going to buy a Seiki 4K (which I wouldn't necessarily advise unless you're fine with zero support response) the 42" has a more current version of HDMI which will matter to you.

All in all, for $250 I'm not unhappy with this purchase, even with the damaged product. I was able to put the steel in a vise and get the TV at least almost vertical, and for an external display for primarily code editing, it's a fantastic amount of pixel space.

But when I glanced over the reviews and noticed that other people also were also getting completely ignored on their RMA requests - that's just bad business.

5 out of 5 eggsWell built!

Pros: So far (4 months) I'm very pleased with the clear clean picture quality. The 4K is impressive. I bought two of them to use for my business which requires me to read construction blue prints from PDF documents. These two replaced a 24" and 42" monitors.The difference is amazing. I can read clearly all the small print and measurements on the screen without enlarging the plans and scrolling all over the place. With the screen resolution set at 3840 x 2160 I can fit a whole page on the screen and read it without scrolling.

Cons: When I set the screen resolution at 3840 x 2160 it flickers when I stream movies. It works great in 1920 x 1080 mode so I won't deduct an egg.

Other Thoughts: I do recommend this product, but catch me in another year to see if it keeps on ticking.

1 out of 5 eggsBad experence so far.

Pros: Looks pretty good. Video from the bunny ears is great. Local TV news and sports in full HD quality.

Cons: The second HDMI port is on top of a weird plastic hub on the back. So you can only use it if the cord has a small or very flexible plug. Also none of the HDMI ports worked. I tried multiple devices and different cables none of the ports worked, no signal on all counts. Understandably, manufacturing flaws happen which is why I returned it.

Just opened the replacement today, and again, none of the HDMI ports worked.

5 out of 5 eggsBetter than I expect, but didn't do what I wanted.

Pros: • easy to use, everything has it's own button on the remote.
• beautifully displays computer desktops
• great deal, cheaper, if not the same price as HD tvs.
• Only thing better would be a bigger one.

Cons: • TV remote too big, a smaller remote could have been achieved.
• In order to take advantage of the 4K UHD feature on the computer, you must be able to use 120MHz on your computer.
• No DVI connection

Other Thoughts: • Make sure you have a good VGA cable for computer displaying.
