Our Verdict

LG CX OLED

TCL R635

The LG CX OLED performs much better than the TCL R635. The LG uses an OLED panel that results in an infinite contrast ratio, perfect black uniformity, and wide viewing angles. It also has better reflection handling, color accuracy, and gradient handling. However, the TCL doesn't have the risk of permanent burn-in, and it gets much brighter.
