But its main functionality is that it routes the Analogix eDP controller to this DisplayPort output, which allows to test that controller simply by hooking it up to a suitable monitor. The Analogix-DP controller supports eDP 1.3 and DP 1.2, so can drive both eDP displays as well as full DP monitors. It does not support DP+ so passive DP-to-HDMI adapters won't work.
