Black Screen

[ZDUDE]

I haven't used ZCentral in about a year, but when I did it was successful. Recently, I updated the sender on my HP and the receiver on my Mac mini M1 and now all I get is a blank screen. How can I fix this?

For the record, I want to use it headless, across wifi on the same network as my Mac. I have already changed the sender config to 1 (from 0) for headless operation. On page 108 of the HPRGSUserGuide, it states:

Black or blank HP ZCentral Remote Boost Receiver window
If the sender is set to less than 24 bit or 32 bit color depth (depending on the graphics adapter), the HP
ZCentral Remote Boost Receiver window might display a black or blank desktop session. Increase the color
depth of and restart the sender usually resolves the issue.

But zero additional instruction on how to do this. How do I increase the color depth of the sender?

If that doesn't work, what else might solve this?

Hello

Apology for delay.  There is a couple of ways to go headless on Windows senders, but you need to have NVIDIA Quadro Graphic cards.  The first being the property you mentioned that you changed from zero to one.  Did you remove the # in front of the property?

## Load an EDID on headless Windows system with Nvidia graphics. Once this property is enabled
## this EDID will not be unloaded until the property is disabled.
Rgsender.Compatibility.Displays.ForceEdidOnHeadless=1

When you edited the file, you must have administrative privileges to make the change, save the file, do not perform a SaveAs as you will get another rgsenderconfig file that is a text file.  After saving the change, you must restart the sender service, or reboot the system with no display attached to have the change take effect.  If you are using a NVIDIA GeForce card, you will need to use EDID emulators to go headless.  If you turn on the headless property, and you want to attach a display later, you will need to change it back to zero, do not add the #, save the file, and again restart the sender to have the change take effect.  Failure to do this will cause a black screen on the display.

The second option is to not use the headless property, and load an EDID file from a display that meets the resolutions needed to be match with your receivers.  I have attached that document.
