[KB1221] Why do I get a black screen when I show videos using ClickShare? (Troubleshooting)

Short Description

Commercial video content with copyright protection (HDCP) will not be displayed using ClickShare and a black screen will be shown. If you are playing a regular video and experiencing issues, it is possible that the video player is using overlays, which prevents the ClickShare application from screen scraping the image. When you disable the overlay setting in your video player, the video will be shown on the central display. Please refer to the manual of the video player for instructions on how to change this setting.

Answer

Commercial video content often uses High-bandwidth Digital Content Protection (HDCP) to ensure copyright protection. Content protected by HDCP will not be displayed using ClickShare and only a black screen will be shown. If you are playing a regular video, it is possible that the video player is using overlays, which prevents the ClickShare application from screen scraping the image. When you disable the overlay setting in your video player, the video will be shown on the central display. Please refer to the manual of the video player for instructions on how to change this setting.
