So even though it can accept an incoming signal with more pixels, it doesn't have enough pixels to display all of them and hence needs to scale the picture down.
What you see in the image below is how the pixels are aligned, and since your projector is 4:3 there's no way of displaying 16:9 material on it without black borders.
It works just the same if you have a 16:9 cinema screen, you cannot fill the entire screen with the image from your projector since the ratio is so different.
Most movies are produced in 2.39:1 and that's why you'll get black borders on most 16:9 projectors and TV's, and there's nothing you can do about it without resizing the image and making people appear taller and thinner.
Thanks, this is informative. I didn't know that Theaters were not 16:9.
I will live with 1024 x 768 (cropped using xbmc), or 1080i input and using the projector option for 4:3 to 16:9.
When I'm ready to buy a new one, will get a Native 1080p 16:9 projector.
