Our Verdict
TCL R635
TCL Q7/Q750G QLED
The TCL Q7/Q750G QLED is better than the TCL R635. The Q750G has much better black uniformity and contrast due to its highly effective local dimming feature, so it’s better suited for a dark room. The Q750G is also much better for gaming due to its HDMI 2.1 bandwidth, up to 4k @ 144Hz support, and lower input lag.
