TCL 55 Class 4k UHD HDR LED Roku Smart TV 4 Series 55S20 review: First thoughts

The 4 series models come in a variety of sizes from 43 to 75 inches. They all have pretty much the same set up: A plastic stand that provides okay stability, three HDMI ports, and direct backlight. They are either powered by Roku or android depending on which platform you prefer.

The TCL 55S20 comes in at 27 pounds and it’s small enough for you to assemble and move on your own. Given its width, you’d probably be better off with a little help. TCL 4 series TVs come with:

  • Three HDMI ports (including one HDMI ARC)
  • Built-in Wi-Fi connections
  • A USB port
  • An ethernet jack
  • An RF connector
  • A 3.5 mm headphone jack

Picture quality

TVs in the 4 Series provide 4K picture quality with 3840 x 2160 resolution. It comes with HDR and direct backlighting. This all leads to higher quality pictures than you would expect from a budget television.

Color accuracy is not as impressive leading to some distortion like orange tones looking a bit pinkish. That’s the biggest issue you will have to worry about when it comes to picture quality.

The HDR feature lacks local dimming so content is not as sharp as it would be on a premium TV like the Sony X900H. The lack of local dimming also leads to black levels not being as rich and deep as you would find on a higher-tier TV.

Motion handling is not as sharp with 4 Series TVs. You might notice some judder when watching a fast-paced scene. Switching on the Motion Smoothing feature helps to reduce this issue.


TCL 4 series TVs come with a Game Mode feature any gamer will appreciate. You get fast response times, and it supports 4K gaming for those planning to get a next-gen console this holiday season. With a signal to screen time of 14ms, TCL 55 Class 4k UHD HDR LED Roku Smart TV 4 Series 55S20 can hold its own even where compared to higher-tier TVs.


C’mon, you know how it goes; these things are called budget TVs for a reason. TCL cut lots of corners with this audio system. It comes with two 8-watt speakers that don’t do much. The volume never really gets loud, so this TV is poorly-suited for rooms with lots of ambient noise unless you connect it to an external audio source.

You don’t get much bass from the speakers either. If you want to enjoy decent sound quality with 4 Series TCL TVs, use a set of headphones or a soundbar. Don’t say we didn’t warn you.


  • Low input lag makes it great for fast-paced games
  • 4K picture quality
  • Great value
  • Affordably priced


  • Weak inbuilt sound system
  • No local dimming
  • Below average motion handling

TCL 55 Class 4k UHD HDR LED Roku Smart TV 4 Series 55S20 verdict: Excellent value for your money

The 55S20 gives you more than you paid for. You get good picture quality for its class and amazing gaming performance. It’s the king of the budget TVs for sure. Click here to read more about 4 Series TVs.
