The PRM-45 and UST projectors’ native resolution is 1280 x 800 (16:10 aspect ratio). As such, it supports widescreen resolution laptops for use with a widescreen (87”/88”/95”) ActivBoard. The projector also supports ActivBoards with a 4:3 aspect ratio (64”/78”) and can therefore be used with all ActivBoards.
This article identifies the correct aspect ratio for each ActivBoard, and the different screen resolutions that can be used with the projector. It also contains information about adjusting your projector to display the image correctly. This article assumes that the projector has been installed correctly and has been tested by the installer.
