As with so many consumer products these days, selecting a projector can be daunting since there are just so many too choose from. However, choosing the right projector is pretty simple as long as you can supply three pieces of information:
The screen size (width, most importantly)
Distance between the projector and the screen (throw distance)
An estimate of the amount of ambient light present in the room in which the projector will be used
At this point you might be thinking, “Great. But I can't answer any of those questions." Or, "I plan to take my projector on the road and could be using it anywhere." Often, with a little forethought, the “I don't know” can be whittled down to a fairly good educated guess. If not, you are not completely out of luck. In addressing each topic, we will suggest your best bet when confronted with unknowns.
