LG’s 84-inch Ultra Definition 3DTV is a proof-of-concept 4K display. The LG set is capable of displaying a full HD resolution 3D image, sending a 1080p picture to both the left and right eye. There is no announced market date for an Ultra Definition TV. It demonstrates that a polarized display is capable of displaying the full 3D images delivered by 3D Blu-ray Discs, undermining one of the unique marketing features of active shutter glasses 3D displays.

Active shutter 3DTVs alternate filling the screen with the full 1080 line left eye and right eye images streamed from the Blu-ray disc. Current polarized 3D HDTVs show the left eye and right eye images at the same time on alternating lines, creating an image with only 540 lines of vertical resolution. This proof-of-concept 4K display matches the resolution of an active shutter screen by using 1080 lines to display each eye’s image.
