Our Verdict
TCL Q7/Q750G QLED
TCL QM6K
The TCL Q750G and TCL QM6K are closely matched. The Q750G is a bit brighter in HDR and in SDR, but in turn, the QM6K has deeper contrast than the Q750G, albeit with more visible blooming. The Q750G has better image processing overall, but the QM6K is far more accurate in SDR out of the box. For gaming, the newer QM6K also has the edge, but barely, due to being able to game at 1080p @ 288Hz; the Q750G tops out at 240Hz. Both TVs can also game at 4k @ 144Hz. Overall, if you already have the older Q750G, it's not worth upgrading to the QM6K, and inversely it's not really worth considering the older set if you're shopping for the newer one.
