I have tested this model and I hope that my Sony XBR75X850D review will help you decide if this model is what you need. This TV belongs to the X850D series. This is a 2016 year model, and it has many functions. This model belongs to the high price category and it may cost you more than $1,000. This model supports the modern 4K video standard.
The Backlight technology is LED (Edge-lit). It has a high refresh rate – 120 Hz (native) providing you with the sharp image even during the most dynamic scenes. The X1 processor assures high performance. The vividness of colors is guaranteed by the HDR technology. It supports various online services, the Google Cast technology and the voice search technology (all accessories are included).
You can control it using a special application (it is available for Android). This model features 4 HDMI ports that support the HDCP technology.
