Our Verdict
TCL Q6/Q650G QLED
TCL Q7/Q750G QLED
The TCL Q7/Q750G QLED is better than the TCL Q6/Q650G QLED. As a higher-tier model in the same lineup, the Q7 just does more than the Q6: more gaming features, better advanced audio format support, much better contrast helped by a decent local dimming solution, and higher HDR and SDR peak brightness. The Q7 is quirkier than the Q6, but all of its quirks are in features or performance capabilities beyond what the Q6 can do.
