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

This review is from: Seiki SE39UY04 39” Class 4K Ultra HD 120Hz LED TV

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

This review is from: Seiki SE39UY04 39” Class 4K Ultra HD 120Hz LED TV

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

2 out of 5 eggsFactory Packed incorrectly

This review is from: Seiki SE39UY04 39” Class 4K Ultra HD 120Hz LED TV

Pros: Works great. Amazing detail.

Cons: It was packed incorrectly at the factory; the TV was in front of the foam backets that are supposed to position the top of the unit within the box. So it was shipped with the the front of the TV against the box, and the unit had shifted up to the top of the box leaving a 4-5" gap where the unit could move freely during shipping.
The unit moved inside the box enough to nearly destroy the protective stick-on plastic film, but the frame and display was unmarked once the film was removed.

Other Thoughts: Overall, it seems to be a good unit. I think I got very lucky that UPS handled the package well and it didn't receive any punctures to the front of the box (which would have damaged the display).

5 out of 5 eggsGreat monitor

This review is from: Seiki SE39UY04 39” Class 4K Ultra HD 120Hz LED TV

Pros: 4K resolution is wonderful for photo editing. I don't have to zoom in to check sharpness. Color is accurate after calibration with ColorMunki.

Cons: The amount of research I had to do for optimal set up as a monitor. Out of the box I was ready to return it. But a search quickly returned the tip of setting sharpness to zero. Next, I had to update the firmware to get the backlight control, which I have set to 50. And then the calibration with ColorMunki took 3 attempts; I had to tilt the screen back 30 degrees to get the sensor to sit flush.

I have a recent NVidia GTX 660 graphics card that easily handles 4k, but I had to experiment with the settings (using RGB output, not YCrBr).

Other Thoughts: There is some mouse lag, but it is almost unnoticeable for what I do. I am not gaming, so cannot comment on suitability for that.

4 out of 5 eggsPretty good value for the price (but not quite there yet)

This review is from: Seiki SE39UY04 39” Class 4K Ultra HD 120Hz LED TV

Pros: 4K at a price that is hard to beat.
As a TV, this deserves 5 stars.

Cons: If you use this monitor for text-based work, you will notice notable aliasing and ghosting. This is particularly obvious for black text on white background.

To reduce it, turn the "sharpness" in the setup menu to 0. I assume Seiki has a built-in sharpening filter that plays havoc with vector images. Setting the sharpness to 0 reduces this but does not eliminate it altogether. So, in summary, this monitor is not quite there yet for text or graphic work.

5 out of 5 eggsExcellent for work

This review is from: Seiki SE39UY04 39” Class 4K Ultra HD 120Hz LED TV

Pros: 4K(30Hz) resolution at reasonable price.
Also a very good HD monitor (120Hz)

Cons: 4K@30Hz only, no HDMI 2.0 or Display port support for 4k@60Hz.

Other Thoughts: It is a nice 4K monitor for work related tasks. HDMI is the only way to get 4K@30Hz to work. If you use Windows 7/8, you may want to get a HDMI adapter to disable monitor detection (search eb ay with "monitor detection") to workaround an special "feature" in Windows 7/8.

1 out of 5 eggsDefective Firmware!

This review is from: Seiki SE39UY04 39” Class 4K Ultra HD 120Hz LED TV

Pros: does 4k

Cons: Turns itself off every 6 hours with the timer circuit set to the OFF position meaning it should never turn off until the user manually presses the off button.

Other Thoughts: Amazing that no other reviewer has noticed this obvious DEFECT!

3 out of 5 eggs

This review is from: Seiki SE39UY04 39” Class 4K Ultra HD 120Hz LED TV

Pros: Desktop Sized.
Great 2K Resolution.
Perfect for TV, Pictures, Documents.
Much landscape!

Cons: HDMI in this unit is 30 FPS Only.
The 120Hz rating is a misleading advertising ploy. 120Hz /4 (1080p areas) = 30Hz (FPS).
Jitter and motion blur as a performance desktop monitor.

Other Thoughts: I tried everything to reduce Jitter to an acceptable level (videocard drivers update, Seiki monitor update x2, NVidia customizing - even a videocard upgrade to GFX-780!) I like the unit very much, but am unable to keep it. RMA City. Looking for a 2K x 60Hz replacement.

4 out of 5 eggsExcellent TV or Monitor

This review is from: Seiki SE39UY04 39” Class 4K Ultra HD 120Hz LED TV

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.

Other Thoughts: No regrets! Quality and surprisingly useful.

Make sure your video card can handle the screen resolution. I upgraded to a GTX 760.
