I have a Zoom Room with a projector and a large format display. The two displays are set to go into standby when no HDMI signal is received from the Windows Zoom PC. It worked great for years.
Recently, Zoom has stopped turning off the displays and just sends a blank (black) signal instead. This isn't so bad for the TV, but is terrible for the bulbs in the projector. I've tried changing the room "Device Operation Time" settings, but I can't get Zoom to turn off the display outputs, it just sends a blank signal.

It seems like you're facing an issue with your Zoom Room setup where the display signal is not turning off properly; instead, it's sending a black signal to the projector. This could be due to several reasons, and here are some steps you can take to troubleshoot and potentially resolve the problem:
Check Display Settings:
Firmware and Software Updates:
Power Management Settings:
Cables and Connections:
Restart or Reboot:
Check for Third-Party Interference:
Contact Support:
Remember to document any changes you make during troubleshooting, and be cautious when adjusting settings to avoid further issues. Additionally, consult the user manuals for your specific hardware and software for detailed instructions on configuring display behavior. Anderson stamped concrete

Hi, Neve.
Zoom Rooms no longer support CEC controls so that might have been the change.
I would recommend checking out the Projector control example and the Zoom Room controls in this article: https://support.zoom.us/hc/en-us/articles/115003340906-Zoom-Rooms-display-systems-on-off

ZzZz,
I use room controls for all my new rooms, but unfortunately this room was built before Zoom documented room controls. There's no network connection to the displays and it could be difficult to add one at this point.
Instead of room controls, there's a device in the HDMI line between the PC and the projector which sends a serial "on" command to the projector when it detects a HDMI signal and an "off" command when the HDMI signal stops. This requires that the Zoom software turn off the display, and not just blank it.
