I've managed to stretch full screen 'gemwin' by loading a message 'fullscreen $1'. This only stretches the window onto the first screen.
How can I get the full screen on my projector (second screen)?

Hi Kandy
thanks for your reply.

Is this function supported by windows 7 as well?

options 2 and 3 on my 'hradio' both stretch the full screen on number 1 screen only
