Peace, mercy, and blessings of God be upon you. Model S90C. A 55-inch Samsung Smart OLED 4K screen. Supports artificial intelligence. Supports Ambilight and mobile screen sharing. It also supports Sony with a 144Hz refresh rate and has many features. In short, I bought the screen because I needed it more than I needed it. I bought it new for over 4000. The screen works as best as it can. Bids are public. May God bless me and the buyer.
