A friend, who knows even less than I do, is giving a series of talks using
Powerpoint images and some movie clips. The venues at which he has appeared
so far have all been equipped with built-in projectors, all with VGA
connectors. He uses a Toshiba laptop.
He is frequently asked to talk at venues that do not have a projector, and
is considering buying one of his own. His first impulse was to drive a
couple of hours to the nearest Harvey Norman and ask the opinion of the kid
behind the counter. (I did say he knows even less than I do.)
What should he buy? It won't get a lot of use, it must be portable and
robust, the higher resolution the better, it must be bright enough to give a
decent picture on a standard sort of roll-up screen. The venues won't be
big: the audiences will be about twenty or so., so they won't be very far
from the screen.
I imagine that a projector has a native resolution and that best results
would be achieved by setting the laptop to that resolution. Is this
so?(Indeed, the built-in projectors seem to allow no options.)
Your insights will be valued.
