UltraHD playback is supported on the Enterprise-level. UltraHD requires a compatible player, such as the Sign Player Ultra model. All apps and functions including uploaded video are supported except YouTube and Vimeo which are not yet fully optimized for 4k but will still look better than when played thru a regular HD player.
