Our Verdict
TCL QM8/QM851G QLED
Sony BRAVIA 7 QLED
The TCL QM8/QM851G QLED is a bit better than the Sony BRAVIA 7 QLED, but it's very close. The TCL is the brighter of the two TVs, with better contrast and a faster local dimming solution, giving it the edge in most room contexts. Still, the Sony model is vastly more accurate in HDR and slightly less so in SDR, and it also has better image processing, so it's the better TV for those who care most about the content creator's intent. Regarding gaming, the TCL is better due to its 4k @ 144Hz and 1080p @ 240Hz support, while the Sony is limited to 4k @ 120Hz.
