Our Verdict
TCL 6 Series 2018
TCL 4 Series 2019
The TCL 6 Series 2018 is much better than the TCL 4 Series 2019. The 6 Series has better dark room performance, thanks to its local dimming feature, and better black uniformity. The TCL 6 Series can get brighter and has a better color, leading to better HDR performance. The 6 Series can display judder-free movies, whereas the 4 Series has a lower input lag, great for games, and a little faster response time, so motion looks slightly crisper.
