What Customers Say

Users reviewing the 77‑inch C‑series models praise the stunning OLED contrast with perfectly black blacks and vibrant colours, along with a brighter panel that makes HDR highlights pop【98878675598448†L225-L279】. They like the refined WebOS interface, HDMI 2.1 ports and support for 4K 144 Hz gaming, and note that low‑quality content is cleaned up effectively【98878675598448†L352-L379】. Drawbacks include a glossy screen that reflects light and insufficient brightness to overcome very bright rooms【98878675598448†L295-L305】. There’s also some stutter due to the instantaneous pixel response and Game Optimizer mode dims HDR more than other modes【98878675598448†L352-L379】. Overall it’s an excellent choice for a home theatre if you can control the lighting.
