Re: About HDCP with Murideo.
ensure the Murideo is set to RGB Video, or 444/420/422
if you can not see below step 16, (after increasing the brightness control), look for a setting on the PJ that will allow you to see below step 16. This may be the HDMI setting, sometimes a picture mode.
Not all PJs will allow for a below step 16 signal to be shown on the screen…ie JVC PJs do not allow for this in the THX mode. That is okay, just set the black level so the steps above 16 are barely visible.
