Our Verdict
TCL R635
LG C1 OLED
The LG C1 OLED and the TCL R635 are different types of TVs. The LG has an OLED panel with a near-infinite contrast, perfect black uniformity, and wider viewing angles. It also has HDMI 2.1 inputs, allowing you to play 4k games up to 120 fps, while the TCL is limited to 4k @ 60 fps gaming. However, the TCL has an LED panel that gets brighter, and it doesn't suffer from the risk of permanent burn-in like the LG.
