No HDMI output when client connects Mac to Logitech Rally Bar Mini Room system

Hey PardoeTechnical,

We'll be happy to help with the connection trouble that you're running into. Just to confirm, are all cables that the device came with connected to the Mac? You mentioned that you do not know the Mac model. Here's how to determine that: Identify your MacBook model - Apple Support. If the Mac model you have does not come with a USB port you may need to look into getting an adapter similar to this: USB-C to USB Adapter - Apple.

If all cables are attached without an issue, see if the concern still happens in safe mode. Safe mode can help tell us if the issue is possible login items. Be aware that internet access is limited in safe mode, but sometimes just starting in this mode and then restarting normally can resolve some issues: How to use safe mode on your Mac.

Keep us updated!

This is a common issue and as you assume it is HDCP related. I had to go through 5 different models of HDMI/CAT6 extenders to find one that functioned as intended. The one we got to works is the DIGITALINK DL-HD70

Hey,

I am an AV Tech as well and I run into this issue all the time. A couple things you can try here.... 1 is to see if you can access the settings of the Transmitter or Receiver that is passing the signal over cat5/6. If its crestron of extron you could use a usb cable or connect to it through the network. There are definitely HDCP settings you can turn off on those devices. The second option is to add an HDMI Splitter somewhere in that signal passage. Splitters do not care for hdcp.
