Samsung Q70D
TCL QM751G
The TCL QM751G is better than the Samsung Q70D. The TCL is better suited for a well-lit room since it gets brighter in SDR. It also delivers a more impactful HDR experience due to its significantly better black levels, HDR brightness, and ability to display a wider range of colors. Regarding gaming, the TCL has a faster response time for clearer motion, and it supports 144Hz for PC gamers.
