Our Verdict
TCL QM7/QM751G QLED
TCL QM6K
The TCL QM7/QM751G QLED 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 QM7K does. It's also capable of gaming at 1080p @ 288Hz, while the QM7 tops out at 1080p @ 240Hz.
