Our take on the TCL 55S451 55" 4K Ultra HDR Smart LED Roku TV
The TCL 55S451 is a 55-inch 4K LED TV with HDR support and the Roku smart platform built in. It sits in TCL's entry-level S4 series, so it covers the basics: a sharp 4K panel, HDR playback, and Roku's app library with a simple interface and voice search through the remote. It suits budget buyers and secondary rooms. Against step-up sets like the TCL Q6 or Hisense U6, it gives up wide color, full-array local dimming and high brightness, so HDR highlights look flatter and dark scenes less even. Reviewers treat it as a solid value pick for everyday watching, not a set for bright rooms or serious movie nights.
- Sharp native 4K resolution
- Roku platform with a large app library and simple menus

Questions and answers
- Is the TCL 55S451 a good TV for the money?
- It is a sensible entry-level 4K set. You get a sharp panel, HDR support and the Roku platform, but not the brightness or contrast of step-up models.
- Does it support Dolby Vision and HDR10?
- Yes. It handles both Dolby Vision and HDR10 content, though the panel's limited brightness means HDR looks subtler than on pricier sets.
- What is the refresh rate?
- The panel is 60Hz, which is fine for movies and broadcast TV but not ideal for fast-paced gaming.
- Do I need a soundbar?
- Most owners find the built-in speakers adequate only for casual viewing. A soundbar improves dialogue and bass noticeably.
- How does it compare with the TCL Q6?
- The Q6 adds quantum-dot color and full-array local dimming for deeper blacks and brighter highlights. The 55S451 is the simpler, more basic option.
- What is in the box?
- The TV, a Roku voice remote, a stand and power cable. A wall mount and HDMI cables are not included.
