6. Sony's professional OLED monitor
Sony's 4K sets make use of the company's super-awesome professional grade OLED monitors for displaying footage in all its natural splendour. The F86 camera can output several different video channels so that different members of the crew can tune into different feeds. The cinematographer needs to be able to see the natural lighting, whereas the camera operators might want to view the footage with different contrast setting so they can see exactly how much detail is being captured in the dark areas of the picture.
