Greetings All: I'm seeking facts re: what to expect when viewing images from a native 16:10 projector on a 16:9 screen. See, while it's always ideal to match the screen's aspect ratio to the projector's native aspect ratio, can anyone tell me what to expect if I put a scaler before the input of the projector, (to help mitigate multiple laptop resolution problems), and want to project onto a 16:9 screen. The pixel width for both aspects is the same; it's the vertical pixel count that is different between them. I realize that if the projector is set to display @ 16:10, the image on the 16:9 screen will be overshot above and below the white section of the screen. But what happens when the projector is configured (via its menu/ rs232) to display @ 16:9? Is the content that would normally be displayed at top and bottom of image cut off? Or is the image vertically compressed to show the entire image and the requisite 'un-needed' pixels in the projector engine turned off? Or what? A call to the projector mfr's tech support yielded the answer that I'd see black bars on the sides of the image.. umm.. no, .. so I couldn't get very far with that tech.
I'm finding that many folksactually do not have a clear valid understanding of this.
Which is ok.. as long as you aren't claiming to know and then offering erroneous info.
I would love to hear from folks who truly understand and can explain.
