[QUOTE="usagora, post: 1853842, member: 60390"] I think we may be using the word "cropped" in two different ways. When I say [B]cropped[/B], I'm referring to literally the bottom half of the dock being cut off (for example). I think you're meaning [B]letterboxed[/B], where the full image of your desktop is projected, but just doesn't fill the entire "lit portion" of the projected image (there are "black bars" at the top/bottom or left/right), like in the 2nd and 3rd images in my OP. My main issue now, again, is with this darn Apple TV not mirroring a 16:10 ration, even when the Apple TV, MacBook, and projector or all set at a 16:10 ratio resolution. That's a complete mystery to me, but I figure it must be something to do with the "Airplay" technology vs. a direct cable connection. The only 16:10 image I can get to display is letterboxed all around (as seen in my 3rd image in the OP). If I could just get the thing to "overscan" to enlarge that image, it could fill the entire lit portion of the screen. But I don't see any way to do that. I'm happy I at least got the wired HDMI connection now working properly, but I'd really like to be able to go wireless too without wasting a perfectly usable portion of the screen with unnecessary letter-boxing. SO frustrating! I think I'll post on the Apple forums tonight and see if any Apple TV gurus might be able to solve this conundrum. I edited one of the photos above to illustrate what I mean by cropped. Something similar to this happens when I try to change everything to 1280x800 when using AirPlay with the Apple TV. There is an "Underscan: on" setting on the Apple TV, but it has no effect on this, contrary to logic. [ATTACH=FULL]31772[/ATTACH] [/QUOTE]
