Samsung CU7000 50" vs Sony X90K 65" (Full Array LED)
The Verdict
Samsung's CU7000 offers exceptional value as a budget 4K TV, delivering solid HDR10+ support and respectable 250-nit brightness for casual viewing at just $279. Sony's X90K, priced at $1099, represents premium performance with its 65-inch Full Array LED panel boasting 1200-nit peak brightness, Dolby Vision support, and 120Hz refresh rate for gaming. Picture quality differences are substantial: Sony's superior local dimming produces deeper blacks and better contrast, while its 8ms input lag and VRR support make it genuinely game-ready versus Samsung's 14ms lag and no VRR. Both share identical 20W audio specs, but Sony adds Dolby Atmos and Acoustic Multi-Audio. For budget shoppers prioritizing essential 4K content, Samsung satisfies; serious gamers, movie enthusiasts, and those with larger viewing spaces should invest in Sony's significantly superior contrast, brightness, and gaming capabilities. Recommendation: Choose Samsung CU7000 for basic 4K entertainment on a tight budget; select Sony X90K if gaming and premium picture quality justify the investment.
