Installation Issues - Short-thow Advantage
I've come across numerous cases where a long throw projector has been installed directly on to the ceiling of the room instead of being 'normal' to the screen (presumably to save money or 'hide' the projector). Trapezoidal correction of the projected image has then to be used to match the screen/whiteboardg giving a different number of pixels for the top and bottem rows of the image on the screen.
The resulting image has a very low effective resolution for text due to the vertical lines crossing pixels.
A short-throw projector would eliminate this problem as it uses a special lens to optically make the correction.
