Our Verdict
LG C3 OLED
TCL QM851G
The LG C3 OLED is better than the TCL QM851G, but they excel in different room conditions. Being an OLED, the LG is fantastic in dark rooms due to its near-infinite contrast, with no blooming or lighting zone transitions. The TCL, however, is far brighter in HDR and SDR, making it the better choice in brighter rooms. Still, the LG is more accurate in HDR and SDR, has better image processing, and is the better gaming TV due to its near-instantaneous response time, so it doesn't really have any weaknesses outside of its lower brightness.
