Our Verdict
TCL QM8/QM850G QLED
LG C4 OLED
The LG C4 OLED is better than the TCL QM8/QM850G QLED, but they excel in different ways. The LG is a dark room standout due to its nearly infinite contrast with no blooming or lighting zone transitions. It's also better for gaming due to its near-instant response time, lower input lag, and four full HDMI 2.1 ports with up to 4k @ 144Hz support; the TCL is limited to two 4k @ 144Hz HDMI 2.1 ports. The LG is also better for a wide seating arrangement due to its vastly wider viewing angle. However, the TCL is much brighter than the LG; it pops even in the brightest of rooms, while you'll want to turn off the lights to get the most out of the OLED.
