did you use a magnifying lens to focus the lcd light or fresnel
i have old slide projector not actully a slide but can i use it is lens or get magnifing lens instead
instead of freshnel lenses I used a light reflecter from a torch light.
magnifying lense and freshnel lenses both are different lenses for clarification refer to similar projects on you tube.
if you have a slide projector lense you can try it in the place of magnifying lenses

best of luck

actually my thought is to prepare a 720p projector,so i took 800x1280 resolution monitor for lcd.
now i am planing for creative 5.1 and curves Screen with white canvas cloth.
for lcd,led,led driver,collimator, Fresnel lens-3,400.
monitor-Rs.3,400.
5.1 Creative surround system-2,400.
screen-Rs.1,200.
So my total expenditure is Rs.10,400.
i used my old pc cabinets part for Magnifying lens with adjustable focal length(i made a small setup for it).
i have searched for a month and decided to purchase ol.with lower cost for all items.
