Consensus
our Verdict

Despite having poor sound and lackluster viewing angles, the Vizio P Series Quantum X is a smart TV that still impresses gamers and general viewers alike thanks to its deep black levels, a wide color gamut, rich picture quality, and pretty high peak brightness.
It scores major points for its local dimming feature and 4K HDR content handling but loses out on the inability to upscale low-resolution content.
