3D
The latest version of the HDMI standard establishes critical infrastructure for implementing 3D video in the home, defining input/output protocols that will allow 3D displays and source devices to communicate through an HDMI link. It¡¯s a major milestone on the path to bringing true 3D gaming and 3D home theater to the mass market, supporting resolutions up to 1080p in 3D.
4K Support
The HDMI 1.4 specification adds support for extremely high video resolutions that go far beyond today¡¯s 1080p systems. 4K is shorthand for 4,000 lines wide by 2,000 lines high, or roughly four times the resolution of a 1080p display. The term actually covers two formats, both supported in the HDMI 1.4 specification:
¡¤ 3840 pixels wide by 2160 pixels high
¡¤ 4096 pixels wide by 2160 pixels high
