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.

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.

Seiki Class 4K

In the unlikely event you have a problem with your Seiki TV, don't worry, the industry's best warranty is there to back you up. Our one-year, no-nonsense replacement policy will make sure you're always satisfied with your Seiki.

4 out of 5 eggsGreat for TV/Movies.

Pros: This television is absolutely great for its true purpose. A TV. In 4k the TV Shows and Movies (especially Blueray) look absolutely incredible. I have been using it as a monitor for the past month and for browsing the internet (Reddit/Facebook/Youtube) it works wonderfully as well.

Cons: It advertises at a 120hz 4k TV. It is in fact not that. It is only at 30hz for 4k. So using it for gaming isn't ideal, but some games you see little to no effect. The lower end games (Graphically wise) I saw little to no difference, but the newer games you can tell a difference and it is bad at 4k.

Other Thoughts: So if you are looking for a television that is just used as a television, definitely pick up this one. It is crisp and clear for ANY TV Show or movie. If you are planning on doing any gaming on it, whether its console or computer, I think it would be best to look elsewhere. Playing games at 30hz is not enough for most games, especially newer ones. Using it as a monitor for your computer works perfectly fine as well, browsing the internet is smooth, running programs seem to be fine as well except the icons are smaller which isn't a big deal at all. Just gaming doesn't work to well on it.

5 out of 5 eggsA steal for the price

Pros: I've had this set now 8 months, with no issues. I bought a Panasonic Blu-Ray player that up-scales to 4K also 4K compatible HDMI cables. Blu-Rays look great, action scenes no problem. I did update the firmware. The set itself looks great, the base is black glass reinforced with a metal plate, the set itself is very thin

Cons: The base mount could have been better, the screws could use metal selves. Would have liked a better remote.

Other Thoughts: the set arrived in 2 days, would buy again.

4 out of 5 eggsupgrade

Pros: It looks amazing to see 4k in 30 fps vids...its best at 2k or 1080p. I put in blurray movie avatar and it looks impressive. played call of duty at 1600x900 on pc no problem.
I put in xbox 360 and was impressed. went to espn preview and it looked sweet. way better than cable espn. i need to xbox 360 to run all stuff i guess

Cons: 4k at 60 fps is a no go. choppy. if i was rich id get the $700 60hz tv...
timewarner looks like 480i, i went to online timewarner and it looked 720-1080i.

Other Thoughts: im still happy that im ready for the future when timewarner goes 4k. goin down to 2k didnt seem to look ok with 2k tv and 4k pics in the future

1 out of 5 eggsWaste of money

Pros: Decent price, ok picture.

Cons: Refresh rate of 120hz is completely untrue. It will do 60hz with a lot of lines during motion.
Can not get the 4k to work no matter what I try.
TV started to make weird noises when turned on while making no other sounds.
Customer service refuses to warranty it because the newegg invoice is apparently not sufficient to prove the purchase.
Spend the extra money and avoid this tv at all costs.

5 out of 5 eggsAwesome screen after some color adjustments

Pros: This screen is fantastic, it is crystal clear and the viewing angle is great as well. I am a professional Forex trader and this screen is aweomse for reading multiple charts at the same time. Before this I had a 24inch 1920*1080p monitor this was a huge jump and now that I have experinced a 4k tv I now can never go back to anything less.

Cons: When I first started this I was disappointed with the colors and the standard settings made everything look dull, but after some color adjustments it looks fantastic.

Other Thoughts: I was very skeptical at first after my dad told me he only paid $375 for this screen at Tiger Direct. But now it is the best screen I have ever owned.

5 out of 5 eggsAmazing Monitor = 4 in 1

Pros: If you are looking to push 3840 x 2160 then look no further. I was skeptical at first with the price thinking you get what you pay for, but this monitor is a godsend and its size/resolution/price is unmatched! It is literally 4 monitors (1920x1080) in one! The 39” makes 4k resolution on a pc highly productive, if you are used to 1920x1080 on a 22” or 23” this is identical text size but 4x the area - AMAZING! I have 8 windows open at once in comfortable view. I highly recommend pushing this with the VisionTek Radeon HD 7750 2GB – it supports 2 of these monitors in full 3840x2160 over a single HDMI cable each. If you are a developer, IT admin, or need multi windows then buy this now - once people understand what this is and how it looks it’s going to sell out fast.

Cons: none

5 out of 5 eggsMust have for Engineering

Pros: THE COST. Nothing else comes close. Despite its idiosyncrasies, most of which Seiki could probably fix with a firmware upgrade (I have 2/14/2014 version), this is still an unbelievable buy. No one should use a monitor over 24" unless its resolution exceeds 1920x1080. This monitor allows me to read full size engineering drawings (42x30 in real life) without zooming in, which is a huge time saver.

My settings are as follows to get a reasonable color rendering:
USER: Contrast 52, Brightness 48, Color 39, Tint 0, Sharpness 0, Color Temp Normal, Blue Screen Off
SETUP: Noise Reduction Off

In the Special Service Menu 0000
Other Settings: TI Mode Off, Swap Mode Off, Backlight 40, Uart Mode Off
LVDS: On, 8, 66K, Off, 1995
DDR Spread: On, 7, 47, 0
VGA Debug: 0, 4400, 2250, 0, 0
Color Temp: HDMI1, Normal, 131, 124, 127, (Offsets) 495, 510, 504
Video Quality: User, 52, 48, 0, 39, Off, Normal

These settings give decent color photographs, but not ideal. As I use this for business apps, it's not an issue.

I'm using a cheap XFX R7-240A-CLH4 Radeon R7 240 2GB video card. Don't expect to stream 4K video and have this card keep up however, but it runs cool and is passively cooled.

Cons: This is a TV, which means you need the remote to turn it on; you can't move your mouse and have it wake up. If you have more than one monitor, when this one goes off, Windows thinks it's disconnected and really screws up your windows, icons, etc (see work around below). Also, the most annoying problem is the backlight; in the special service menu (Menu then 0000 on the remote) the backlight will say 40, but it's really 100; as soon as you go up to 41, then it fixes itself. But! you have to do this every time you turn on the TV.

From time to time the monitor starts a 60 second countdown to turn off; make sure you have the remote nearby. I'm not sure what causes it, but it happen a few times a week.

Other Thoughts: Make sure you get AutoHotKey for Windows so you can write scripts to arrange windows with hot keys. If you have more than one monitor and the Seiki is your primary, this is a must have, otherwise you have to reconfigure your windows every time the monitor turns off.

4 out of 5 eggsR7 240 PC graphics card did 4K nicely

Pros: Light weight, bright, includes 4K-worthy HDMI cable, good viewing angle means corners do not look dark even if you sit close to monitor. Highly recommended for high-resolution (4K, 8-megapixel, 30Hz refresh rate) non-gaming computer monitor. Probably works great at ordinary 1080p resolution even for gaming, where the monitor can refresh at 60 or 120Hz or whatever..

Cons: Out of box the monitor turns itself off when the computer tries to merely put the monitor to sleep. This means the user has to turn the monitor back on with the remote control after a computer has attempted to simply put it in power-save mode, a mild annoyance that people seem to quickly get used to. Will check to see if there is some way to fool around with that in the secret "advanced" menu that you get to by pressing MENU, then typing in 0000.

Only learned about how to turn off the auto-shutoff after many hours, from other reviewers here.

Other Thoughts: Important to turn off the sharpness, i.e. set it to zero, at least when using this thing at 4K resolution with Microsoft Windows. Otherwise bright sharpening halos appear around small dark text characters (that some users don't even notice).

Put in a power-hungry dual fan GTX 660 video card for one 4K resolution user. Worked great but in retrospect seemed overkill (since had to change out the power supply so as to get multiple extra power cables for the video card which can also draw high wattage). Next user, Newegg has a FANLESS R7 240 video card for something like $70 dollars that works great at 4K resolution and probably draws about 25 watts.

Look forward to updating firmware via USB slot and the advanced menu.

1 out of 5 eggsBad experience for me

Pros: It is a 4k for 300-500 dollars. If it worked it would give good space for doing coding work etc on my PC.

Cons: The first one sent to me had rattling parts inside it. It turned on but I RMA'ed it since it had something broke in it.

The second one came and did not have that issue. The screws that screw in to the base strip super easy. The plastic piece that goes along the top of the tv easily can be pulled away from the tv \ cheap easy to break. The buttons for the input on the side of the tv are cheap as well. The included HDMI cable while looking cool with blue braided cord did not display anything when hooked between my PC and the TV. Another cheap cord I had laying around did.

Now I can look past all of that....if it worked. But putting a good HDMI cable between my brand new 2k computer and this tv resulted in the image showing fine for a few minutes then every 30 -60 seconds the screen goes blank the image then redisplays and the TV displays in the upper right corner the resolution and refresh. So it is like the tv thinks it needed to change resolution (similar to if you had changed inputs).

Now I hook the PC to my other Vizio 60 inch tv and no problems, same PC, same cord, doing the same things on the computer - no black screens.

Hard to resist for the price but man what a junk paper weight.

That said I do have a co-worker who has one at work and uses it daily without the issue. The main thing he sees is the mouse lag. He uses it for coding and has his work PC hooked to it.

Take your chances if you want but know what you might end up with.

Other Thoughts: Now shopping for a real monitor
