Our Verdict
Vizio P Series Quantum X 2019
LG C9 OLED
The LG C9 OLED and the Vizio P Series Quantum X 2019 use different panel types, each with their strengths and weaknesses. The C9 is better for a dark room, and it has incredibly wide viewing angles. The C9 also has a nearly-instantaneous response time, outstanding low input lag, and some great future-proof features, like 4 HDMI 2.1 ports. As an OLED TV, the C9 does have a risk of permanent burn-in. The Quantum X, on the other hand, is much brighter, and small highlights in HDR movies look much closer to what the director intended. There is also no chance of burn-in with the Quantum X.
