Our take on the TCL 65S451 65" 4K Ultra HDR LED Smart Roku TV
The TCL 65S451 is a 65-inch 4K LED smart TV in TCL's entry S-Class line, running the Roku TV platform with HDR10 support. It covers the basics well: a big 4K screen, Roku's simple interface, and the streaming apps most people use. It is a budget-focused set, so it skips the mini-LED backlight, wide color and high brightness of TCL's QM and Q-series models. Buy it for size and streaming value, not for a bright room or serious movie viewing.

- Roku TV platform with a straightforward interface and broad app support

What reviewers say
Owners of TCL's entry 4K Roku sets generally call them good value for the size and easy to live with, while noting the picture is basic. Most praise the Roku interface; complaints center on contrast, brightness and sound.
- Picture qualityMixedOwners say 4K streaming looks sharp, but blacks are gray and the picture is dimmer than pricier sets.
- Roku platformPraisedReviewers like the simple Roku home screen, the remote and the wide app support.
- HDRCriticisedHDR10 content looks flat because the panel lacks the brightness and color range to show it off.
Questions and answers
- Is this TV good for a bright living room?
- Not really. Its brightness is modest, so glare and daylight wash out the picture. It suits dimmer rooms better.
- Does it support Dolby Vision?
- No. It supports HDR10 only, not Dolby Vision or HDR10+.
- Is it good for gaming?
- It is basic for gaming. The 60Hz panel and limited brightness suit casual play, not fast competitive games.
- Do I need a streaming box?
- No. Roku is built in, with the major streaming apps and a tuner, so no extra device is needed.
- How does it compare with TCL's Q-series TVs?
- The Q-series adds quantum-dot color and, on some models, mini-LED backlighting for much better contrast and brightness. This set is the simpler, cheaper option.
- What is in the box?
- The TV, a Roku remote, a stand and power cable. Check the listing for the exact remote and stand included.
