Back in 2008, Apple introduced the new Mini DisplayPort<\/a> standard as the only video output method on the new MacBooks and LCDs. Mini DisplayPort is a freely-licensed VESA standard [1] and has now been adopted by a number of other display manufacturers, and is a miniaturized version of the original DisplayPort<\/a> interface.<\/p>\n

This week, the fourth revision of the HDMI high-definition video output connector was revealed in the form of HDMI D, weighing in at a mere fraction of the original HDMI connector size and intended for use with mobile and embedded high-definition video devices [2]. The new HDMI connector is expected to ship later this year, and is in direct competition with VESA’s Mini DisplayPort interface.<\/p>\n

VESA is the international governing body for computer graphics standards, and has been designing video output standards since its conception in the late 80’s [3]. HDMI is a private group formed in 2002, and licenses its interfaces out to manufacturers at four cents a device + a $10,000 yearly fee.<\/p>\n

HDMI doesn’t have many (if at all) advantages over DisplayPort, besides support for the xvYCC color space and Dolby audio codecs (as a part of the licensed technology). However, despite the licensing costs, HDMI has proved popular mainly due to its original mass adoption as a result of being signal-compatible with the DVI interface [4].<\/p>\n

The new HDMI-D interface is smaller than the Mini DisplayPort, though both have the same maximum resolution\/bandwidth and similar power requirements. The numbers are as follows:<\/p>\n\n\n\n\n\n\n
