This machine has an NVidia NVS 3100M with a displayport output.
When using a displayport to HDMI adaptor feeding an HDCP compliant monitor, the Nvidia control panel tells me that the setup is not HDCP compliant.
In addition, when I select the monitor for HDMI audio in the Nvidia control panel, it does not appear as a windows playback selection.
All the latest drivers for the card (including Nvidia High Definition audio) are installed correctly.
The displayport to HDMI adaptor works fine with audio when used on a different PC.
Can anyone suggest what to check next? Thank you.
