The TCL US5800 Series UHD LED has an average picture quality for a 4k TV. It has a bit more blur than ideal on fast sequences. The screen of the US5800 also produces harsh reflections that can't get countered by the low TV brightness. The Roku smart platform is great though and the TV operation is user-friendly.

The TCL US5800 is a good looking TV although a thick one. It is mostly made of plastic except for its feet that are made of metal.

The TV isn't attractive from the back. It has a few different level of thickness so it might look strange when wall mounted. When it is, most of its connections won't be blocked which is good.

From the side, the TV is fairly thick and has an unattractive design which reminds of older LCD TVs.

Picture Quality

Watching movies on the TCL US5800 is decent. DVDs and blu-rays play smoothly but judder is present in movies from other sources. With high quality content the picture is detailed enough but some low resolution content doesn't exhibit the same performance. Out of the box, the colors of the TCL US5800 are a little off. On the good side, watching dark scenes, even with all the lights off, offers some interesting depth. Unfortunately, the US5800 doesn't support higher end features like HDR, 3D or local dimming.

Looking at the screen from up close you can notice a strange pixel pattern. This only occurs when the 'color temperature' setting is set to warm. You can see the pixel picture here.

Update: From further testing we have concluded that all current TCL TVs that we have reviewed do not display 4:4:4, but 4:2:2. This is due to the TV inputs accepting 4:4:4 but actually displaying 4:2:2. 4:2:2 is better than 4:2:0, but slightly blurrier for text than 4:4:4.

Bottom right: TCL FS3750 (48FS3750).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

Although the TCL US5800 has good value for the price, other 4K TVs offer better picture quality and might be worth investing into because of this. Not all TVs are as good when it comes to smart functionalities though.

Vizio D Series 4k 2016
40" 50" 55" 58" 65"

The Vizio D 4k 2016 is a better TV for sports and video games since it has less motion blur. It also has less reflections on its screen which makes for a better fit in the living room. It isn't as good for low quality content like for watching DVDs though.

TCL FS3750
40" 48" 55"

The TCL FS3750 might not be a 4k TV but delivers better sports and video games performance with the same Roku smart platform offering. Pick this TV if you sit farther away than about 6 feet from the TV.

Samsung KU6300
40" 43" 50" 55" 60" 65" 70"

The Samsung KU6300 is more expensive but is a better TV. It has a better picture for low quality content like DVDs, can get a lot brighter and is more suitable for video games.

Conclusion Amazon CHECK PRICE Right

For a 4k TV, the TCL US5800 isn't terrible but still at the bottom of the range. For most usages, 'average' would be the word to summarize its performances. It has more blur than ideal, its colors aren't that good and the fact that the TV can't get bright emphasis its reflections issues. The main strength of the TCL US5800 is really its strong Roku smart platform.

I like that you guys are starting to add other brands to your reviews. I'm particularly interested in the new Hisense 4k TVs. Especially since they are growing more in the US and have made their way to Best Buy. Models (H7&H8). I read they bought off Sharp companies in Mexico. Also, to help with a question asked earlier, Best Buy has vendor reps within their store. Our store has reps from Samsung, Sony, LG, Apple, Microsoft, etc. They are not allowed to sell other brands and therefore that is why some people feel a sales associate will push a brand.
We don't have plans to review the Hisense TVs at the moment, however your request has been noted and if there is enough interest we will. Thank you for the additional information.

Please review the Hisense H8 HDR Series.
Thank you for your interest. We still have several major brand TVs to review so if we come to Hisense that will be later this summer or in the fall.

Great review. The box in store says 120Hz but in review it says 60Hz. Could you please explain?
Manufacturers use a different number for marketing which doesn't correspond to the real refresh rate of the TV. We measure the TV to determine the true refresh rate. See more information here.

This review, luckily, came in the day after my old Samsung 56" LED DLP TV just up and died and this one came up when I was looking for a relatively inexpensive, replacement TV to go at least a few years. Are the TCL UP(130/120) models better panels in terms of response time, color, etc? The other major option seem to be the Vizios, likely the 1080P, because I game or use a 1080P HTPC 80% of the time, but I found the 55" TCL UP120 cheaper than both this model or either Vizio 55"s.
The TCLs we have reviewed have had comparable picture quality to the Vizio D series, although that is not a sure indicator of the 55UP130 which will be reviewed in the next couple of weeks. Unless you are sitting very close and watching mostly 4k content, don't spend more just for 4k. The smart platform is one of the strongest features of TCL, however as you'll be using a HTPC it isn't necessary.

On the resolution section why did it receive a 9 at 1080p with its problems stated if other high end tv's i.e. Samsung KS8000 received the same 9 at 1080p? Thank you
The pixel patterns were only visible within about 2ft of the TV, and this is not an issue at all when viewing it normally.

Great review. Do you know if this television is similar to the UP120/UP130 releases? Will you be reviewing those models as well? Thanks.
We expect the UP120/UP130 to be similar to the US5800 but we will know for in a couple of weeks when we will review them.
We are not taking any more questions for this product because we no longer have it in our lab.
