Version 1.4a
Introduced in 2018, the latest version added improvements to compression, error correction and multi-stream transport (see VESA Display Stream Compression, forward error correction and MST).

With passive cables, "dual-mode" DP (++ logo) connects to TVs via HDMI. However, earlier Mini DP interfaces did not support HDMI audio. To connect Mini DP to an HDMI TV required a split cable that merged DP video and USB audio into a single HDMI plug. See HDMI.
