4k TV, MOVIES and DVD's
Do I have to have 4K everything, or do they all upload to 4k from regular and Blu-ray?
TV and movies are not made in 4k yet. the 4k TVs just upscale everything into 4k for now. the only thing that comes in 4k so far are the newer gaming systems such as Xbox one and recently ps4. FYI: A 4k high speed HDMI cord is required to give proper picture and performance.
