Even modern packetized display interfaces like DisplayPort are still fundamentally a one-way firehose for the pixel data. There's no provision for acknowledging data packets, and forward error correction is optional. The bidirectional sideband channels used for stuff like EDID are not timing-sensitive like the pixel data stream.
