Type LED
Resolution 4k
Refresh Rate 60 Hz

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.

Our Verdict

7.0 Mixed Usage

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.

Pros
  • Great smart platform
Cons
  • More blur than ideal
  • Not suitable for a bright living room
  • Average screen uniformity
  • 7.0 Mixed Usage
  • 7.0 Movies
  • 6.7 TV Shows

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 two feets are made of metal with a silver finish.

Footprint of the 55" TV stand: 9.1" x 39.8"

Back
Wall Mount VESA 200x200

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.

Gray uniformity isn't good. Corners of the screen are darker, banding can be seen both vertically and horizontally (even at a slight angle) and some color tints can be observed.

From the side, the picture of the US5800 deteriorates but not as much as some other LED TVs.

Update: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results.

8 bit gradations can be seen in our gradient pattern. Also, some tints of colors are present in the gray gradations. This shouldn't much of a problem in normal content though.

The only possible way to calibrate the TV is with the Roku application. There they offer color space, 2 point and 11 point settings. Calibrating the television was a nightmare, and very time consuming. Some errors couldn't be fixed.

480p Input

480p upscaling is a little inconsistent. It sometimes looks slightly blocky. There are worse TVs than this one though and most won't notice.

The TCL US5800 does a better job with 720p content like cable channels, once upscaled the image looks good.

9.0
Picture Quality
1080p Input

1080p looks detailed enough. Closer than about two feet away from the TV, the pixel sub-structure can be seen. This can't be seen farther away and is not an issue.

9.5
Picture Quality
4k Input

4k offers rich details. As in 1080p, from very close, the pixel substructure can be seen but is a non-issue from afar.

The trail following the logo is a little bit long and has a darker yellow tint. The US5800 has an unusual backlight flickering. The PWM frequency is 200Hz, which isn't a multiple of 60Hz. Visually, it produces a shaking duplication of fast moving objects.

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.

Roku is the smart platform that offers the most apps. All aren't great but the most popular ones are there.

Smart OS Roku

Roku is the smart platform on the TCL US5800 and it delivers great smart features. It has thousands of apps including most of the popular ones. Its interface is quick and the menus and remote are straightforward for anyone to use. The fact that this TV doesn't have a lot of options plays favorably for its user-friendliness. The US5800 also has a lot of inputs which is great.

Differences Between Sizes And Variants

We tested the 55" (55US5800). For the most part, we expect our review to be valid for the 65" (65US5800).

If someone comes across a different type of panel or if their TCL US5800 doesn't correspond to our review, let us know and we will update the review.

Compared To Other TVs

Comparison picture

Top left: LG UH7700 (55UH7700). Bottom left: Samsung KU6300 (UN55KU6300). Middle: TCL US5800 (55US5800). Top right: Vizio D 4k 2016 (D50u-D1). 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.

Hisense H8C
50" 55"

The Hisense H8C is a better TV than the TCL US5800. It has deeper blacks, higher peak brightness, better reflection handling, better motion handling, HDR compatibility, and slightly better built-in speakers. On the other hand, the TCL uses Roku's smart interface which has a wide array of apps and is easy-to-use.
