Best of luck everyone deciding which TV to get.
So if one wants to run game mode (and thus decrease the horrible input lag) they must set game mode on each and every time they turn on the monitor or change modes.
Clinical Tools
The picture is great (crystal clear, bright, vibrant colors), and to my surprise the sound quality is amazing for a flat panel.

After returned a defective-on-arrival Seiki 39" 4K TV, I turned to TCL, hoping to have a better luck.

After unboxing and routing testing under 1080p, I found this TV to be superior than Seiki on the following aspects:
1. Much nicer looking frame, perfectly flat, and less glares;
2. Better 2K->4K up-conversion picture quality;
3. No dead pixels, no weak pixels, zero!

But things turn up-side-down when I started 4K testing. When I switched to the advertised native resolution (3840x2160), all I got is a cropped, blurry image! It looks like the original 4K input has been scaled down to 2K in 4:3 aspect, and then scaled back to 4K.

I tried to adjust every possible options in the menu (including every options in the service mode menu), none helped. I also tried all 4 HDMI input, none helped. I tried 4K input from three different computers (all worked with my previously returned Seiki TV), all show the same phenomenon (blurry image, cropped at top and bottom).

It seems that this TV is not capable to properly displaying 4K input signal at all!

Since I am quite satisfied with all other aspect of this TV, I will try to contact TCL support first to see if there is a fix to this problem. But if this issue could not be resolved, I would have no choice but return it to Amazon again :( -- 4K TV couldn't display 4K input? What a joke...

Took a picture of the TV showing at 4K (3840x2160) [...]
The down-scaling of the input is very obvious -- you can hardly recognize the text on the screen!

Update: the contact page of TCL USA webite ([...] is non-functional. I typed up my issue and click "submit", and it shows "loading..." forever. Never received email confirmation that my issue was received.

***I added 5 pictures with notes to this review & updated the firmware.***
As with all early adopters, I expect technology to improve as the latest gadget matures. That will be the case with this 50 inch TCL 4K TV. The current limitations of HDMI 1.4 (3840×2160 at 24 Hz/25 Hz/30 Hz) means that this is not going to be the fastest display next year (2014). But at the astounding $750 price point for a 50 inch 4K TV in 2013, it's a bargain.

Also, since true 4K source material is almost nonexistent except for a few (rather lame) 4K YouTube and Vimeo videos, you are left with so-so up converted 1080p content. All of the so-called "4K BluRay discs" are rubbish (in 2013) so do not waste your money. They are regular 1080p discs with clever marketing!

My setup is a Sony STR-DN1040 receiver with 4K HDMI 1.4 inputs and various sources, the primary being a Generation 3 Apple TV. BluRay 1080p is provided by an unlocked Pioneer BDP-330 and Playstation 3. Additional 1080p content is via a modified Linux-based Generation 1 Apple TV with a Crystal HD card.

Also connected via the Sony amp is a Apple Macbook Air and Apple Mac Mini (both 2011 models). Their max output via Thunderbolt is 1920x1080 to this TV; I have not been able to increase the resolution beyond that yet but I have SwitchResX so I will experiment further to see what I can get. <edit> The reason I could not get resolutions above 1920x1080p is I needed Accell B086B-008B UltraAV Mini DisplayPort 1.1 to HDMI 1.4 Active Adapter - AMD Eyefinity Certified (Blister Package) so I ordered it from Amazon and I will experiment some more and report back.

For those having "ghosting" issues or lip sync problems (input lag) make sure you change tv ADVANCED settings. These will be located under menu>picture>advanced settings.

Cable TV via HDMI - Film Mode OFF, MEMC Mode OFF
If you are still having the issues, turn Game Mode ON, as a last resort at a slight expense to picture quality. Turning MEMC off should take care of it.

Blue-Ray - MEMC OFF
Film mode helps here movies are filmed at 1080p/24, this mode sets your tv at that setting (Don't worry it will still look great, just watched Star Trek Into Darkness...Awesome. Game Mode ON again if all else fails.

PS3/most likely xbox 360 (dont have) - MEMC OFF Film Mode OFF
Turn Game Mode ON

Really enjoying this TV after some playing around with settings.

Current settings...
Brightness 50
Contrast 40
Saturation 50
Sharpness 20

Just got off the phone with TCL customer service. I was curious about the firmware update, even though I am not experiencing problems, so I tried to visit their website (, which was all jacked up. Apparently they are using now, in case anyone else is confused about that. Also, he could not confirm whether or not this TV will support HDMI 2.0 in the future via another firmware update. This is exactly the same situation as with Seiki. TCL customer service seems alright though... I was never put on hold and got a real person within a minute of calling!


I'm not going to review every feature of this TV. Other people have written great reviews with some great tips. What I want to do is help you decide which which inexpensive 4K TV to go with - TCL or Seiki. Now, I have two other TCL LED TVs which have never given me any issues, but I decided to buy the Seiki 50" 4K TV when it went down in price around black Friday. I got one of the used Amazon warehouse deals, so I expected an imperfect TV. Turns out, the corner was broken, the stand was missing screws, and the screen had a small line of dead pixels, so I ended up returning it. However, I did put it through some tests before returning, and I found that it had great image quality after messing with some settings, and the resolution and upscaling looked great. If it hadn't been broken I certainly would have kept it.

After returning the Seiki, I decided to go with this TCL (one of the warehouse deals again) and I do not regret it one bit. This TV seems to be as good or better in nearly every aspect.

- The stand feels much more sturdy.
- The front bottom bezel is thinner and more stylish.
