Our Verdict
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.
- Great smart platform
- More blur than ideal
- Not suitable for a bright living room
- Average screen uniformity

Popular TV Comparisons
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.
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.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
