I was adjusting the position of our projector to allow for bigger prints to be generated.  I encountered a problem that at larger distances, our prints are not seeming to adhere as desired.  

Does the inverse square law of light apply to DLP projectors?  

I am aware that the inverse-square law only is 100% applicable when you have a point as your light source.  But I assume close to the same holds constant for other real world light sources.  

Unless DLP projectors compensate for distance with their power output. Is this the case?
