DisplayPort IP Core Video Interface is BGR Rather Than RGB

Environment

  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    According to the DisplayPort MegaCore Function User Guide, the DisplayPort IP core sends and receives video on its video interface in RGB format. However, in fact the IP core sends and expects video data in BGR format. (For color depth n, blue is communicated in bits [3n-1, 2n] and red is communicated in bits [n-1,0]).

    Resolution

    To avoid this issue when connecting to other video components with known video format, swap the connections as appropriate.

    This issue will be fixed in a future version of the DisplayPort MegaCore function.
