LG B5 OLED vs TCL QM8K: Which TV Is Better?

The TCL QM8K and the LG B5 OLED have different strengths, so the best one ultimately depends on your needs and where you plan on using it. The TCL is the better choice for daytime viewing or if you like to leave the lights on at night, as it gets a lot brighter and can overcome more glare. The LG, on the other hand, is the better choice for a dark room, as the OLED panel delivers deeper, more uniform blacks with less distracting haloing around bright parts of the scene.
