Projector Software

Does anyone have any idea how you wirelessly connect to a data projector - from Kubuntu?
Hitachi and Epson projectors.

I have tried Mkchromecast but it crashes on launch.
I have tried Gnome Networkmanager Display, but it crashes straight after launch and turn off the wifi.

If you need a walkthrough through your problem guided by others, you need to provide much more information about your issue.
