Our Verdict
TCL QM6K
TCL QM751G
The TCL QM751G is better than the TCL QM6K in almost every way, as the QM7 is brighter, has better black levels, has better image processing, and is more colorful overall, delivering a more impactful viewing experience. The QM6K is, however, more accurate and follows the content creator's intent more closely than the QM7K51G does. It's also capable of gaming at 1080p @ 288Hz, while the QM751G tops out at 1080p @ 240Hz.
