Our Verdict
LG B8 OLED
Vizio P Series Quantum X 2019
These two TVs are different types, each with its advantages and disadvantages. The LG B8 is an OLED TV with perfect blacks and excellent dark room performance, wider viewing angles. The Vizio P Series Quantum X 2019 is an LED TV that can get much brighter suitable for very bright rooms and doesn't have a permanent burn-in risk.
