In some cases, video destinations such as displays and projectors operate in a nonstandard mode.
This mode of operation may cause in some cases an unsuccessful HDCP interaction causing no picture/ video on the display.
As an example, we found this issue while working with a Lilliput TK1330-NP/C.
Below are the Lilliput display specifications and EDID file for reference:
- Native resolution is 1920×1080p at 60Hz (16:9)
- Only supports HDCP 1.4, (according to the vendor)
- Input signal type Digital (DVI)
Suggestion
Make sure to perform a proof of concept with the destinations planned to be used before full deployment.
