Our Verdict
TCL Q750G
TCL QM5K
The TCL Q750G and the TCL QM5K deliver similar overall picture quality, but the Q750G has the slight edge. The Q750G is slightly brighter in both SDR and HDR, particularly in scenes where the entire screen is brightly lit. The Q750G is also better suited for gaming, as it achieves a higher refresh rate with its native 4k resolution.
