Note that the input type for our projectors is ANALOG (even though it's tied to a digital computer the video output fed to the projector is ANALOG).
If the projector has been set to digital input it won't display anything as we don't feed it a digital input.
The choice between analog or digital input is under the menu system for the projector's #1 input. David Hunter says it's reachable via an unlabeled select button. If that doesn't take you to it you can either poke around in the menu system a bit (being very careful not to change anything else), or you can refer to the Proxima 92xx Series Manuals.
