The Verdict

Samsung's CU8500 delivers solid 4K performance at an exceptional budget price, featuring HDR10+ support and acceptable 11ms input lag for casual gaming. However, Vizio's P-Series Quantum substantially outperforms it across nearly every metric: the 65-inch panel offers dramatically superior brightness (1200 nits vs 350), full-array local dimming for superior contrast, 120Hz refresh rate with VRR for gaming, Dolby Vision HDR, and Wi-Fi 6 connectivity. Picture quality differences are pronounced,Vizio's quantum dot technology and backlighting create noticeably deeper blacks and more vibrant colors. While both use identical 20W audio systems, Vizio provides an extra HDMI port. At double the price, Vizio targets serious gamers and movie enthusiasts willing to invest in premium picture quality. Samsung CU8500 suits budget-conscious buyers seeking basic 4K streaming; Vizio P-Series Quantum is the clear choice for those prioritizing visual excellence and gaming performance.
