When the macs ( new power mac and macbooks) are connected to a promethean interactive whiteboard and programs are opened, the display on the whiteboard and the laptops immediately changes size and expands outside the screens.
We have tried adjusting display options but this hasn't helped. Any help please?
GarageBand (Mac) '11, Mac OS X (10.6.8)
While hooked up, under displays, arrangement, try unchecking mirroring if it is.
It sounds like overscan. Is there not an overscan slider in the Displays preferences for that display? And you can't find any resolution that solves the problem?
One last question -- does this thing require any driver(s)?
Right, like this it's treated as second monitor, so it won't mess with the resolution. Launch your app, and drag it to the left or right off the screen, you should see it show up on the whiteboard. You can also make the white board the main monitor by going to displays, arrangement, and drag the little bar ontop of the screen, to the other screen. This is also where you dictate the orientation of the screens, ig. if the white board is to the left of you, drag that screen to the left.
Thanks but we can't find a slider or a display setting that helps. Laptop display changes as soon as we plug in the whiteboard but is still workable. However GarageBand and iMovie are unacceptable.
Technically software is not required for the board but l'm waiting on a reply from Promethean.
Yes this is a short throw. We are reluctant to alter projector settings as it works fine with windows.
Promethean will be on site for a pd in two weeks so maybe they can sort the problem then. Thanks.
Afraid this didn't help. Only a blank desktop appears on the whiteboard when mirror image is unticked.
This wasn't successful either. The program still expanded outside the boundaries of the screen.
So this is projected via a short throw projector? Perhaps the answer lies in the projectors settings. Have you poked around in there?
