Our Verdict
TCL QM8/QM850G QLED
TCL QM7/QM751G QLED
The TCL QM8/QM850G QLED is better than the TCL QM7/QM751G QLED. The QM8 does most things noticeably better than the QM7; it has better contrast with local dimming enabled, a brighter presentation in HDR and SDR, is more accurate in SDR prior to calibration, and has much better reflection handling. The QM7 does have a slightly wider viewing angle, but they're both underwhelming in that regard. Overall, the older 2023 QM8 is still a notably better product than the newer yet lower-end QM7.
