The EST-P1 projector’s 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 tested by the installer.

EST-P1 projectors sold before January 2012 did not have this feature. If this is the case, the aspect ratio should be set up in the Aspect Ratio menu.

  • Using the right arrow key navigate to Installation I
  • Now press the down arrow key so that Aspect Ratio is highlighted
  • Press the select key
