LG C4 65" vs Vizio P-Series Quantum 65"
The Verdict
LG's C4 represents the pinnacle of OLED TV technology, delivering exceptional picture quality with its OLED evo panel, 1300-nit peak brightness, and Dolby Vision IQ support. Its α9 Gen 7 processor excels at upscaling and motion handling, while the 60W speaker system with Dolby Atmos provides immersive audio. Gaming performance is outstanding with 1ms input lag and full VRR/ALLM support. Vizio's P-Series Quantum offers solid value as a quantum dot LED alternative, featuring full-array local dimming that approximates contrast control, though it lacks OLED's perfect blacks. At 8ms input lag and 20W audio output, it's competent but noticeably behind for gaming and immersion. The $800 price difference heavily favors the Vizio for budget-conscious buyers seeking basic performance, but the LG C4's superior contrast, color accuracy, processing power, and gaming credentials justify its premium for discerning viewers and gamers.
