Unified Display Interface
The Unified Display Interface ( UDI) should replace imported in 1986 VGA port. It should be compatible with the digital DVI connection, in addition to transfer audio data as well as - as well as the DVI - compatible HDMI - HDCP support the signal encryption.
UDI provides 16 Gbit / s about three times higher bandwidth than DVI ( 5 Gbit / s), which would have enabled a lossless display control with screen resolutions of up to about 3840 × 2400 pixels at 60 Hz refresh rate and 8 bit resolution per color component. Optional was a digital audio transmission available, which can be omitted for pure PC applications for applications in consumer electronics. For an HDMI license must be purchased and the user needs a special adapter cable from UDI to HDMI from the device manufacturer.
UDI should, and device- internal video connections, such as between the display controller and the display panel are used, for which a special function profile is applied. The electrical interface specification should be modeled on PCI Express. Additionally, an event-driven feedback channel has been provided, and it will use a new, compact plug. The final specification was published in July 2006. Care was taken to a maximum compatibility of UDI to HDMI.
After Samsung and Intel have completed at CES 2007 its support for UDI and Apple is followed in October 2008, a larger distribution of the standard is unlikely, was declared a VESA standard especially since the competition technique DisplayPort. The website of the UDI Special Interest Group also no longer exists since the beginning of 2008.
