We want to project the display from ORIN onto a HUD. Our HUD only supports an HDMI interface, so we added an HDMI-to-DP cable to connect the HUD to ORIN. However, we found that there is no image displayed on the HUD. If we replace ORIN with a regular computer running Ubuntu and still use the HDMI-to-DP cable to connect to the HUD, the HUD displays the image correctly.

Why is that? Is there a solution?
