The all new model SONY BRAVIA KD-65A1 is one of the best televisions the company have ever brought in.I bought the same 1 month before.Now I could comoletely feel the difference in clarity compared to my old one.The model has a 65 4K led display.As in all other smart tv, it also is provided with an app store.The operating system is android 6.0 mashmallow.But unlike other smart tvs, it is easy to operate in sony bravia according to me.As it is a 65 telivision it has got some weight about 30 kg.One of its best features is its sound system.It consists of a dolby digital sound system.The sound makes us the feel in a theatre.There are 4 HDMI ports and 3 usb ports( one at the side and 2 at the bottom) .As a whole I am completely satisfied with its new features.
