Sony X900F series design has been modified compared to that seen on LCD TV 2017 models. The frame uses a dark aluminum finish, while the base is composed of two supports in the shape of “L” that widen outward. This solution has also been studied to allow a perfect integration with the new HT-XF9000 soundbar. The table support also allows you to keep the cables tidy so as to channel them towards the back of the TV, concealing them from view.

To control the backlight, both in SDR and in HDR is X-tended Dynamic Range Pro, able to precisely adjust the brightness levels for each area of the screen. Sony speaks of a contrast ratio 6 times higher than that of a conventional TV without local dimming. So, the performance should be higher than 2017 models, credited with a contrast ratio 5 times higher than conventional television.

Sony X850F series includes Triluminos display for greater color accuracy, 4K X-Reality Pro technology to improve the rendering of details, there is also Digital Assistant, integrated Chromecast, access to Google Play and HDR10 compatibility. The series comes in only two 65″ and 75″ screen sizes.
