Our Verdict
TCL QM8/QM850G QLED
LG C3 OLED
The LG C3 OLED is mostly better than the TCL QM8/QM850G QLED. The LG has a much wider viewing angle, so it's more suited for watching TV as a group. The LG also has a faster response time, so there is less blur behind quick motion, and its nearly infinite contrast ratio delivers inky blacks when viewed in a dark room. However, the TCL is a much brighter TV, so highlights stand out more in HDR, and this TV can overcome more glare in a very bright room. The TCL is also an interesting option for PC gamers with high-end graphics cards due to its 4k @ 144Hz support.
