The 55, 65 and 77 inches are the QD OLED panels, make sure the model number has FXZC at the end of it.This is an absolutely gorgeous TV. I’m so proud of Samsung for making such a masterpiece. The visuals are drop dead gorgeous, it is so vibrant, colorful and bright. It can be as accurate or as saturated as you want.The stand for the TV could have been better though. But I do like the fact that it doesn’t take up much space on the TV stand.This TV will blow your mind whether you are watching a show, movie or playing games on it. Overall 10/10 experience. Highly recommended!
