Sony X90K 65" (Full Array LED) vs Vizio M7 Q-Series 55"
The Verdict
Sony's X90K dominates with its larger 65-inch panel, superior full-array LED backlighting delivering 1200 nits of brightness versus Vizio's 600 nits, and gaming-focused features including 120Hz refresh rate, VRR support, and 8ms input lag. Vizio's M7 Q-Series compensates with modern Wi-Fi 6 connectivity, HDR10+ support, and aggressive $499 pricing for the 55-inch model,a $600 savings. Picture quality favors Sony significantly; its full-array local dimming and double the peak brightness create substantially better contrast and HDR performance. However, Vizio delivers respectable 4K content handling at a fraction of the cost for smaller living spaces. Sony X90K is the superior entertainment display for dedicated home theater setups, while Vizio suits budget-conscious buyers prioritizing value over peak performance.
