physical interface and protocols, which are not directly compatible with DisplayPort and are not applicable to external connection, however they enable very high resolution and refresh rates while providing simplicity and extensibility. iDP features a non-variable 2.7GHz clock and is nominally rated at 3.24Gbit/s per lane, with up to sixteen lanes in a bank, resulting in a six-fold decrease in wiring requirements over FPD-Link for a 1080p24 signal; other data rates are also possible. iDP was built with simplicity in mind so doesn't have an AUX channel, content protection, or multiple streams; it does however have frame sequential and line interleaved stereo 3D. PDMI Portable Digital Media Interface (PDMI) is an interconnection between docking stations/display devices and portable media players, which includes 2-lane DisplayPort v1.1a connection. It has been ratified in February 2010 as ANSI/CEA-2017-A. wDP Wireless DisplayPort (wDP) enables the bandwidth and feature set of DisplayPort 1.2 for cable-free applications operating in the 60GHz radio band. It was announced in November 2010 by WiGig Alliance and VESA as a cooperative effort. SlimPort SlimPort, a brand of Analogix products, complies with Mobility DisplayPort, also known as MyDP, which is an industry standard for a mobile audio/video Interface, providing connectivity from mobile devices to external displays and HDTVs. SlimPort implements the transmission of video up to 4K-UltraHD and up to eight channels of audio over the micro-USB connector to an external converter accessory or display device. SlimPort products support seamless connectivity to DisplayPort, HDMI and VGA displays. The MyDP standard was released in June 2012, and the first product to use SlimPort was Google's Nexus 4 smartphone. Some LG smartphones in LG G series also adopted SlimPort. SlimPort is an alternative to Mobile High-Definition Link (MHL). DisplayID DisplayID is designed to replace the E-EDID standard. DisplayID features variable-length structures which encompass all existing EDID extensions as well as new extensions for 3D displays and embedded displays. The latest version 1.3 (announced on 23 September 2013) adds enhanced support for tiled display topologies; it allows better identification of multiple video streams, and reports bezel size and locations. As of December 2013, many current 4K displays use a tiled topology, but lack a standard way to report to the video source which tile is left and which is right. These early 4K displays, for manufacturing reasons, typically use two 1920×2160 panels laminated together and are currently generally treated as multiple-monitor setups. DisplayID 1.3
