Our Verdict
TCL S4/S450G
TCL S5/S551G
The TCL S5/S551G is better than the TCL S4/S450G. While both have a somewhat limited contrast ratio and no local dimming, the S5 gets noticeably brighter, resulting in better overall picture quality, especially in brighter rooms. It also has a better viewing angle and wider color gamut, as well as offering more gaming features, like VRR and 1080p or 1440p @ 120Hz.
