The Good The affordable TCL 6 series has excellent overall image quality, with deep black levels, very good brightness, rich contrast and accurate color. Its Roku smart TV platform is the best available, with a simple interface and extensive streaming app support. The TV handles both HDR10 and Dolby Vision high dynamic range sources.
The Bad Brightness and video processing fall short of some more expensive TVs.
The Bottom Line With superb picture quality that rivals TVs costing twice as much, TCL’s 6 series is the best TV value we’ve ever reviewed.
