Moreover, it is this device through which the company is expecting to mend its sinking ship. The Xperia 1 sports World’s First 21:9 aspect ratio which the company is calling the CinemaWide aspect with the 4K resolution with HDR OLED display. Obviously, all the content cannot be viewed in the 4K resolution and for non-4K content, it uses the adaptive display. The color accuracy is top notch and is touted to be the same as the Hollywood Studio productions.
