I'm currently looking into purchasing my first projector. I've spent the past couple days researching and learning as much as i can, but I have a couple of questions. My understanding is that native resolution means the actual physical number of pixels. So if a projector spec sheets lists its native resolution as "SVGA (800x600)" and it's max resolution as "UXGA (1600 x 1200), 1080p", how does it achieve this? From what i have read it sounds like the larger max resolution is just a stretched image, and that to create the HD 16:9 aspect ratio it cuts off part of the top and bottom of the image. So how does it create a 1080p image from a 800x600 physical source? Is it not a true 1080p image? The actual projector i'm looking at is an Optoma GT360. It's spec sheet can be found here: http://www.amazon.com/Optoma-GT360-Projector-Great-PlayStation/dp/B003B4DFH2/ref=sr_1_1?ie=UTF8&qid=1299783725&sr=8-1 My second question is when part of the image is cut off the top and bottom to change a 4:3 aspect ratio to a 16:9, is some light still projected to that cut off area?
