Our Verdict
TCL R635
Hisense U7K
The Hisense U7K is better than the TCL R635. The Hisense has better black uniformity and a much better local dimming feature for deeper blacks than the TCL, so it’s the better option for a dark room. The Hisense is also much better for gaming due to its HDMI 2.1 bandwidth, up to 4k @ 144Hz support, and lower input lag.
