In looking at ads for several different front projectors, I've noticed several specifications for resolution. Native, maximum, and compatible.... Can anyone shed some light (!) on the differences? Can you notice a difference between using the native and a compatible (HD 720p or 1080i)?

How do they show a 16:9 picture if the "native" resolution is not in that ratio? Bands top and bottom?

Thanks in advance for your comments.
