Our Verdict

Hisense U9N

TCL QM851G

The Hisense U9N and TCL QM851G are similar. The Hisense has the better contrast with local dimming enabled and has a wider viewing angle, but the TCL is noticeably brighter in HDR and SDR and is a bit more uniform than the Hisense. Still, the Hisense is a bit more accurate, especially in HDR, and its response time is more consistent when VRR is enabled.
