Our Verdict
LG C1 OLED
Vizio P Series Quantum 2021
The LG C1 OLED and the Vizio P Series Quantum 2021 are different types of TVs. The LG has an OLED panel with a near-infinite contrast, perfect black uniformity, and wide viewing angles. The LG also has a much faster response time for better motion handling, and even though they each have similar gaming features, there are fewer bugs on the LG, providing a better gaming experience. On the other hand, the Vizio is an LED TV that gets much brighter so highlights pop in HDR, and it doesn't have the risk of permanent burn-in like OLEDs.
