You can already disable the wallpaper changing very quickly though:
- Right-click the DisplayFusion icon in the taskbar tray
- Click "Random Wallpaper Changer"
- Select "Freeze Current Images"

This will prevent the image changer from doing anything while the images are frozen. This setting will be reset on the next restart, or by unselecting the freeze option. I hope this helps. ]]> https://www.displayfusion.com/Discussions/View/enhancment-request-306-detection-of-a-vnc-connection/?ID=9d324f3e-1960-41c4-9cf5-a9debefba26d#5 Tue, 07 Jul 2009 07:35:50 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/enhancment-request-306-detection-of-a-vnc-connection/?ID=9d324f3e-1960-41c4-9cf5-a9debefba26d#5 DisplayFusion How about making hotkey to do so?
Thus, experienced user just press the keys when he connect to VNC/RDP server.

But then there is a question about turning off this mode. Solutions:
1. Hotkey...
2. Catch server blocking (because of this is most oftenly used action when VNC/RDP client disconnects).

Also, for RDP please review this:

There is a way to check for RDP, easily, though... VNC, however is a whole new ballgame. ]]> https://www.displayfusion.com/Discussions/View/enhancment-request-306-detection-of-a-vnc-connection/?ID=9d324f3e-1960-41c4-9cf5-a9debefba26d#3 Mon, 06 Jul 2009 22:39:06 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/enhancment-request-306-detection-of-a-vnc-connection/?ID=9d324f3e-1960-41c4-9cf5-a9debefba26d#3 DisplayFusion I have checked into this, and I don't think it's going to be possible. I can't reliably detect a VNC session, without coding support for each VNC variation or monitoring TCP ports. There just isn't a reliable, safe way to do this. ]]> https://www.displayfusion.com/Discussions/View/enhancment-request-306-detection-of-a-vnc-connection/?ID=9d324f3e-1960-41c4-9cf5-a9debefba26d#2 Mon, 29 Jun 2009 14:46:36 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/enhancment-request-306-detection-of-a-vnc-connection/?ID=9d324f3e-1960-41c4-9cf5-a9debefba26d#2 DisplayFusion Excellent idea! I'll extend the RDP option to say "RDP or VNC". Hopefully this will make it into the 3.1 release. Thanks! ]]> https://www.displayfusion.com/Discussions/View/enhancment-request-306-detection-of-a-vnc-connection/?ID=9d324f3e-1960-41c4-9cf5-a9debefba26d Fri, 26 Jun 2009 18:03:23 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/enhancment-request-306-detection-of-a-vnc-connection/?ID=9d324f3e-1960-41c4-9cf5-a9debefba26d DisplayFusion There is currently an option for suspending wallpaper changes during a Remote Desktop Sesssion (RDP), but I use RealVNC (http://www.realvnc.com) which is significatnly better than RDP and includes encryption and many other features. It would be really nice for DisplayFusion to detect if the local PC is being controlled though a VNC session and suspend wallpaper updates. ]]>
