Consensus
our Verdict
The TCL S4/S450G is a basic entry-level 4K television that lacks any advanced features. It performs about as well as you might expect for a cheap television with a low 60Hz refresh rate and low peak brightness levels. The TV offers a high native contrast at 8,300:1 for better dark scene performance, but highlights don’t stand out without local dimming.
Regarding gaming, the TCL S4 offers a low input lag of 11.2ms, which is suitable for gamers. However, the TV doesn’t offer VRR support and only provides 3 HDMI 2.0 ports, so you can’t take full advantage of modern consoles’ advanced display capabilities.
ReasonS to Buy
Low 11.2ms input lag
Good native contrast ratio
Decent reflection handling
Google OS is user-friendly

Reason to Avoid
Low peak brightness levels
