Our Verdict
Hisense U6N
TCL Q651G
The Hisense U6N is better than the TCL Q651G. Thanks to its local dimming feature, the Hisense displays much deeper blacks, so it looks better in a dark room. The Hisense also looks better in a bright room since it overcomes more glare, and it provides a more impactful HDR experience thanks to its wider color gamut and better HDR brightness. The Hisense allows you to drop your resolution to play in up to 1440p @ 120Hz, but VRR doesn't work when you do that. The TCL can output up to 1440p @ 120Hz with VRR active, but since its pixel transitions are so slow, it's not a good option for gamers.
