Our Verdict

Vizio M Series Quantum X 2022

Vizio P Series Quantum 2021

The Vizio P Series Quantum 2021 is better than the Vizio M Series Quantum X 2022. They have similar peak brightness, but the P Series has much better reflection handling, so it's a better choice for a bright room, as glare is less distracting. The P Series also has much better contrast, making it a better choice for a dark room, as blacks are deeper and more uniform.
