Our Verdict
TCL 5 Series 2018
TCL 4 Series 2019
The TCL 5 Series S517 is a bit better than the TCL 4 Series S425. The S517 can get brighter and is more suitable if you have a bright room; it can display a wider color gamut, which helps HDR performance. Also, the S517 has a motion interpolation feature to please the soap opera effect fans and can display judder-free movies. The TCL S425 has somewhat lower input lag, which is great for video games, and delivers a little crisper motion thanks to the faster response time.
