Our Verdict
LG C5 OLED
TCL QM8K
The LG C5 OLED and the TCL QM8K trade blows, and the best one really depends on your usage and personal preferences. Although the TCL has fantastic contrast, it's still not as good as the OLED C5, so blacks aren't quite as deep, and there's some noticeable haloing around bright highlights. This makes the C5 the better choice for a dark room. The TCL, on the other hand, is significantly brighter, so it's the better choice for bright room viewing.
