Product Description

Size: 50 Inches

Watch your favorite TV shows and movies in eye-popping Ultra High Definition. With more pixels for an even better resolution, UHDTVs provide a more immersive, clear picture experience for everything you play on them.

From the Manufacturer

Simply Brilliant

Seiki believes everyone deserves a well-made TV, and goes to great lengths to make sure its TVs are the highest quality and available at a fair price. Seiki believes the next ‘big thing’ is a great television that offers the same clarity of video and audio featured on the higher priced TVs–without the add-ons that bring the higher price. Seiki is part of one of the largest manufacturers of TVs in the world. This allows Seiki to create considerable efficiencies that it gladly passes along to customers. Seiki starts with only the most advanced panels for the highest picture quality and uses high performance amplifiers to power its speakers. Seiki TVs are made in its own facility by its own people. Not only does this cut out a costly middleman, this also allows Seiki to maintain a high level of quality control that meets its own strict standards.

Key Features

4K Ultra HD Technology

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.

Connect all of your devices

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.

Upscale your entertainment to 4K

With Seiki 4K 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. 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 4K Ultra HD glory.

Seiki 4K One Year Warranty

Seiki 4K Customer Service

No 4K content? We've got you covered

Most Hollywood movies are produced in 4K Ultra HD but delivered to consumers as HD or lower resolution content. With the new generation of 4K Ultra HDTVs now on the market, the challenge is to transform this legacy content into enhanced 4K digital entertainment experience for the living room. Together with a Seiki 4K Ultra HDTV, U-VISION 4K upscaling HDMI cable offers state-of-the-art video processing and 4K performance enhancements comparable to native 4K. (Sold separately.)

One-Year Replacement Warranty

At Seiki, we believe that when you make a great TV, standing behind it is easy and simple. To us, this means offering a comprehensive one year replacement warranty. If there is an issue with our TV during the first year, we will do our best to provide a resolution. If we are unable to, we promise to replace your TV.

Customer Support

Seiki offers toll-free customer support from its U.S headquarters in California to provide setup and technical assistance to Seiki TV owners.

Updating the firmware seems to have solved this.

Anything below 120hz for 1080p looks pretty awful and 4k resolution isn't an option beacuse of the 30hz refresh rate.

Size Name: 50 Inches Vine Customer Review of Free Product ( What's this? )
The Seiki 4K TV's are relatively new and have recently made some headlines with being one of the first manufacturers to build a 4K TV for a fraction of the price of the competition. There are many questions that I have such as what, if any, sacrifices were made to get such a low price, how does it work as a PC monitor, gaming possibilities, blu-ray, low-def content, etc. So let's jump in and see how it does!

DESIGN & INPUTS:

First thing to note is how the TV is being used. It's in a medium sized Media/Game room that measures about 14' x 13', give or take a few inches. There are 2 windows with blackout curtains. And I'm normally sitting anywhere from 4 ft (at my desk) to 11 ft (couch) away. This room has a couple of computers, so it's used as an office / game & media room (aka "man cave").

The TV is only about 2" deep and has thin ¾" border around the screen. However, there is a larger "base" at the bottom where the included stand mounts. This protrudes towards the back another 1". It also only weighs about 50lbs.

The TV is currently sitting on a mobile TV cart with it's included stand so I can roll it around as I compare it to my Toshiba 50L2200U 50-Inch 60Hz LED-LCD HDTV that is mounted on the wall. I wanted time to review before making a commitment to replace the already pretty darn awesome Toshiba. :) It's only about a foot lower and is using the same sources. The stand is a bit wobbly if you bump it, but I shouldn't need it for long.

There is also a 2" wide LED "bar" on the front of the TV that changes from blue (on) to red (off).

This review is for the Seiki SE39UY04, a 39" 4k TV

tl;dr 4k@30Hz, under $400, blanking issues, not good for games or videos @ 4k. **UPDATE** 6/20/2014 - Update with SE50UY04 firmware. I now recommend this product.

The old adage, "you get what you pay for" definitely holds true with this product.

First a little about my setup; I am using this TV as a computer monitor for CAD/productivity applications. I do not intend to play games with this TV, but I used to be an avid gamer so I will make a few comments there. While I do watch a decent amount of videos, I do not have any that are 4k, so there would be no advantage over my other TV, although I did watch some snippets for this review. I am using the included HDMI cable **UPDATE** 6/20/2014 - I am using the AmazonBasics High-Speed HDMI Cable Supports Ethernet, 3D and Audio Return (3 Feet/0.9 Meter) to connect the HDMI1 input to the HDMI 1.4 port on my laptop (i7-4700MQ, GTX 770M). All of my testing was done at the 4k resolution, because if I wanted a 1080p screen I could choose much cheaper and smaller screens than this one.

Pros:
- 4k (3840 x 2160) resolution.
This is a huge difference in CAD programs. I do a lot less panning, scrolling and zooming in/out, all of which saves time.
- 39" diagonal.
I thought this was going to be a con before I bought it because I sit fairly close to it, but I realized that it is large enough that text is easily readable on the screen (without changing any accessibility settings), and small enough that it still fits on the desk somewhat comfortably.

Size Name: 50 Inches Verified Purchase
Ok. I got this in the mail today and wasn't sure if it would work with my hp dv7 laptop with an intel hd3000 graphics card (HDMI only out). When I first opened and connected to this monitor the resolution defaulted to a maximum of 1920x1080 @ 24 Hz. It was pretty sharp but the last TV I had was just as sharp at that resolution.

So I spent all day working with different modelines to try to manually get the resolutin right. The monitor was impressive and would display all kinds of modes between 1920x1080 and 3840x2160. BUT. They were all kind of blurry and would not have worked to program all day on.

Well after about 4 hours of working with random timings and resolutions I thought I would try xrandr with the 3840x2160 modes untill I found one that very closely matched an hsync of 30. I found the closest line that I could get to 30hz was:

root@dv7# cvt 3840 2160 13.8
# 3840x2160 13.79 Hz (CVT) hsync: 30.05 kHz; pclk: 144.25 MHz
Modeline "3840x2160_13.80" 144.25 3840 3944 4320 4800 2160 2163 2168 2180 -hsync +vsync

I guess you could find something closer but that was close enough. So I ran:

xrandr --newmode "3840x2160_13.80" 144.25 3840 3944 4320 4800 2160 2163 2168 2180 -hsync +vsync
xrandr --addmode HDMI1 "3840x2160_13.80"

Those make it so you can select it in the Displays or monitors section depending on your distribution (make sure you have the right HDMI port by running xrandr without any arguments).

If you don't know where the monitors section is you can run (leave off the quotes):

xrandr --output HDMI1 --mode 3840x2160_13.80

Anyway after I ran that and the monitor came back from being black... BAM! Super high definition and huge display! I was so happy I cried a little.
