Overview
At 50 inches, TCL's S451 series brings 4K UHD resolution and Roku's smart platform to a value-tier LED television, giving direct access to streaming apps without a separate box.
This model sits in TCL's value tier, using standard LED backlighting rather than QLED or mini-LED, which keeps the price down but trades away some of the brightness and color range of the pricier sets in this batch. Ethernet is listed too, giving a wired option for buyers whose Wi-Fi struggles with 4K streaming.

Who it's for
Good fit for budget-focused buyers who want a 50-inch 4K set with Roku built in and do not need the higher refresh rates or QLED color of premium models. Less suited to gamers wanting high refresh rate support, since none is listed here.
Strengths and trade-offs
Drawn from this product's published specifications.
- Roku smart platform built in for app streaming
- 4K UHD resolution at 50 inches
- Ethernet port for a wired network connection
- No refresh rate listed above standard
- Standard LED rather than QLED backlighting
Performance notes
Standard LED backlighting delivers the core 4K picture without the extra brightness and color volume of QLED, a reasonable trade at this size and price tier. Roku's interface is one of the more app-complete smart TV platforms, so streaming service coverage should be broad out of the box. Ethernet support gives a stable wired connection option alongside whatever Wi-Fi the panel includes.
