"One recent audio/video connector interface is DisplayPort which had version 1.0 approved in May 2006 and is supported in a few computer monitors. Currently no CE displays or AV receivers have been released that support DisplayPort and the DisplayPort website states that DisplayPort is expected to complement HDMI."There are a few advantages that HDMI has over DisplayPort such as support for the xvYCC color space, Dolby TrueHD and DTS-HD MA bitstream support, CE control signals, and compatibility with DVI. DisplayPort has an advantage that it is currently royalty free which might allow it to be cheaper to implement while the HDMI royalty is 4 cents per device. Most of the DisplayPort supporters are computer companies with its largest supporter being Dell which has released two computer monitors that support both DisplayPort and HDMI."
"There has been no announcements made about UDI since early 2007 and the UDI website is no longer operational. [...] In early 2007 Samsung and Intel withdrew from the UDI SIG and no further announcements about UDI have been made since then."
