LG OLED C2 55" (Evo) vs Samsung QN90C 65" (4K Neo QLED)
The Verdict
LG's C2 OLED delivers exceptional picture quality with perfect blacks and infinite contrast at a significantly lower price point, featuring a sleek 1.6-inch profile and impressive 800-nit peak brightness. Samsung's QN90C counters with a larger 65-inch screen, superior peak brightness reaching 2000 nits for bright room performance, and Mini-LED backlighting that excels with HDR content and gaming at 144Hz. Both handle gaming identically with 6ms input lag and VRR/ALLM support. The C2 edges ahead in color accuracy and contrast-dependent content, while the QN90C dominates in brightness, size advantage, and overall brightness uniformity. Audio-wise, Samsung provides slightly better immersion with Object Tracking Sound technology versus LG's standard 2.2ch setup. For cinephiles prioritizing picture quality in controlled lighting, the LG C2 offers superior value. For bright living rooms and larger screen preference, Samsung's QN90C justifies its $500 premium.
