LG OLED C3 65" (Evo) vs Samsung S90C 55" (4K OLED)
The Verdict
Both TVs deliver exceptional OLED performance, but they target different priorities. LG's C3 offers a larger 65-inch display with Evo panel technology and 900 nits brightness, making it ideal for bright rooms and cinematic viewing. Samsung's S90C compensates with superior brightness at 1300 nits peak and QD-OLED technology, delivering punchier HDR and better gaming versatility through 144Hz support in Game Mode. Picture quality differences are subtle,both excel at contrast and color accuracy. Gaming is practically identical with matching 6ms input lag and VRR support. Audio outputs are comparable at 40W. The LG provides better value overall with a 10-inch size advantage at just $200 more, plus superior software integration and webOS's user-friendly interface. However, if you prioritize a compact 55-inch form factor with superior brightness and bleeding-edge brightness capability, Samsung's S90C justifies its premium. For most buyers seeking the best value-to-size ratio with excellent OLED credentials, the LG C3 is the stronger recommendation.
