I have an NEC VT-540 and would like to know if it is better to mount it at the shortest distance I can? If I zoom all the way in and then fill my screen will I get a better picture than say half zoom? Oh also when I check the information tab while a DVD is playing it tells me the source is 640x 480. This projector will do 1024 x 768. Is it my dvd player,(older proscan). I do run svideo through an iscan with rgb cable to the projector. thanks
