HDMI 1.4a was released on March 4, 2010, and added two mandatory 3D formats for broadcast content, which was deferred with HDMI 1.4 pending the direction of the 3D broadcast market. HDMI 1.4a has defined mandatory 3D formats for broadcast, game, and movie content. HDMI 1.4a requires that 3D displays implement the frame packing 3D format at either 720p50 and 1080p24 or 720p60 and 1080p24, side-by-side horizontal at either 1080i50 or 1080i60, and top-and-bottom at either 720p50 and 1080p24 or 720p60 and 1080p24.
Products are not required to implement all features of a version to be considered compliant with that version, as most features are optional. For example, displays with HDMI 1.4 ports do not necessarily support the full 340 MHz TMDS clock allowed by HDMI 1.4; they are commonly limited to lower speeds such as 300 MHz (1080p 120 Hz) or even as low as 165 MHz (1080p 60 Hz) at the manufacturer's discretion, but are still considered HDMI 1.4-compliant. Likewise, features like 10 bpc (30 bit/px) color depth may also not be supported, even if the HDMI version allows it and the display supports it over other interfaces such as DisplayPort.
