One of our staff has an interactive whiteboard and PRM-30A projector, hooked up to a Toshiba C660 notebook using VGA.
Everything was working fine until we had to re-image the notebook with a fresh version of Windows 7.
Now when he switches on the notebook and projector the sides of the projected image appear slightly cropped. For example, if you start ActiveInspire half the logo on the top window bar is lost. It’s the same on the right hand side of the display.
Pressing “auto set” on the remote control resizes everything properly. This works fine until the notebook goes to sleep, which can be regularly enough since we have a low timeout value set for staff. This is frustrating our colleague…
Is there a way to permanently set the parameters which an “auto set” discovers? Or is there something missing on the notebook following the re-installation of Windows? Or is there some calibration we missed?
We don’t have much experience with Promethean projectors, so any advice would be appreciated.

Thanks for posting.
From what you have mentioned it sounds like there is a different screen resolution that is set than what was previously.
We have the below Support Article which will help depending on the size ActivBoard you have:
Please ensure that you are using the correct screen resolution for your size ActivBoard and also double check that the aspect ratio is correct on the projector.
I hope this information helps.

Thanks Adam. I had a look at aspect ration but this was set OK. In case other people have the same problem I discovered it was the value of the projector parameter Menu….PC Adjust…Horizontal.
By increasing this slightly it right shifted the whole display so that the left hand side of the Aspire window was visible. The cropping on other side of the screen seemed to be a non-issue after all.
Remember to store the Horizontal setting once it’s been adjusted, otherwise it’ll revert back when the projector is switched off.
Kind regards, Mark.

Thank you for your response.
We are glad to know the image has been adjusted correctly and we will leave this thread open so other people can see the solution in case they experience similar issues.
