TCL 50S451 Tv Review
Our verdict
The TCL 50S451 is a 50-inch 4K Roku TV at $400, but its 3.8 average from just 38 reviews makes it one of the harder TCL models to recommend with confidence. You can find well-reviewed 4K Roku alternatives at similar prices.

38 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other LED, QLED and OLED TVs plus TV mounts, streaming media players, antennas, cables and satellite gear we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The TCL 50S451 offers 4K UHD resolution on a 50-inch LED panel with Roku built in. At $399.99 it sits in the competitive 50-inch 4K range. Roku is a reliable and simple smart platform that consistently ranks among the fastest and easiest to use at any price. The TV connects via Ethernet and weighs 18.5 pounds in a 10.1 x 43.8 x 27.1-inch chassis.
The 4K picture combined with Roku's interface is a genuine draw, but the spec sheet is thin. No refresh rate is listed, no HDR format is confirmed, and connectivity beyond Ethernet is not detailed. Those gaps make direct comparison with alternatives harder.
The weak point here is the feedback data. 38 reviews averaging 3.8 stars is the thinnest review pool for a current TCL 50-inch model. Whether the score reflects early production issues, specific feature gaps, or simply a limited buyer sample is hard to say. Buyers should weigh this uncertainty against the Roku platform advantage.
Pros
- 4K UHD resolution at a 50-inch size that suits most living rooms
- Roku smart platform is one of the simplest and most reliable smart TV systems
- Wired Ethernet connection available for a stable streaming link
- TCL is a well-known brand with solid retail support
Cons
- Only 38 reviews at 3.8 stars leaves major uncertainty about reliability
- No refresh rate published, unknown for gaming use
- Connectivity details beyond Ethernet are not listed
- No HDR format is confirmed in available specs
