Our Verdict
LG C1 OLED
TCL 6 Series/R648 2021 8k QLED
The LG C1 OLED and the TCL 6 Series/R648 2021 8k QLED are different types of TVs. The LG is a 4k TV with an OLED screen, so it has much better contrast, better uniformity, wider viewing angles, and a quicker response time than the LED panel on the TCL. Since the LG is a 4k TV, it displays native 4k resolution better than the 8k TCL because it doesn't have to upscale it. On the other hand, the TCL's higher resolution supports 8k signals, and it gets much brighter, so highlights pop more in HDR. The TCL also doesn't suffer from the risk of permanent burn-in like the LG.
