Our Verdict
Hisense U6N
TCL QM751G
The TCL QM751G is better than the Hisense U6N. The TCL has better black levels, HDR brightness, and more vibrant colors, so its image quality is superior overall. The TCL also has HDMI 2.1 bandwidth and supports up to 4k @ 144Hz, making it a better gaming TV. Furthermore, the TCL does a better job upscaling low-resolution content and has a wider viewing angle, meaning it's more versatile overall.
