Our Verdict
LG SK8000
TCL 6 Series 2018
These two TVs have different panel types, each with its advantages and disadvantages. The LG SK8000 has an IPS panel and is a better choice for a room with a wide seating arrangement, as the image remains accurate when viewed from the side. The TCL 6 Series 2018 has a VA panel and has a much better dark room performance with deep blacks, thanks to the high contrast ratio and better local dimming support. The 6 Series can get brighter and is more suitable if you have a bright room. The 6 Series has a wide color gamut and can deliver a much better HDR performance.
