Our Verdict
TCL 6 Series 2018
LG UK7700
The TCL 6 Series 2018 is a better TV than the LG UK7700. The TCL has a VA panel and can display deeper blacks and brighter highlights due to the better contrast ratio and better brightness, so you'll enjoy watching movies and HDR movies more on the TCL. On the contrary, the LG UK7700 has an IPS panel and is better for watching TV shows and sports, as it can better handle the reflections of a room with many light sources, has better gray uniformity, and has wide viewing angles to accommodate for wide seating arrangements.
