LG OLED C9 Series 4K Smart TV vs Vizio P Series Quantum X 4K HDR Smart TV P65QX-H1
Verdict: The LG OLED C9 delivers perfect blacks and 120Hz motion that the Vizio P65QX-H1 cannot match (RTINGS contrast scores: 10/10 vs 7.2/10). The Vizio counters with 2000-nit peaks and lower used prices but trails in viewing angles and color volume. For dark-room cinematic use the C9 remains the stronger choice despite its age.
Winner: LG OLED C9 Series 4K Smart TV
LG OLED C9 Series 4K Smart TV: 8.5/10
Vizio P Series Quantum X 4K HDR Smart TV P65QX-H1: 7/10
