ATV3 & 2013 MacBook Retina
When I use airplay desktop mirroring, and set to use the ATV display ratio . . .
It works, the MacBook display changes ratio to match the TV 16:9. But the ATV does not completely fill the screen. There is about a 2 inch black border all around the TV image. So my 46" TV looks like a 42" TV. When I turn off airplay, the Mac screen goes back to normal and the TV screen is full again.
Apple TV (3rd generation)
In looking at this again, the border is really only about 1" all around, making my 46" TV more like a 44" TV.
On your tv remote push the aspect or format button to change the format of the screen. You will be able to adjust it so that the apple screen fits perfectly in your screen
So I would have to adjust the TV every time I go into airplay (and change it back when done)? I suppose I could do that, but what a pain. Since the regular ATV display fills the screen, you would think you could use airplay without doing tv adjustments. No one would do that.
Ya it's a pain but that what I do when inairplay my apple stuff
I was having the same issue. I discovered a setting in the Apple TV Video settings.
Adjust For AirPlay Overscan
it was ON, so I switched it OFF and poof the screen is now 1080 and not compressed into a smaller area with a black border. not sure why this would be ON be default without some kind of first run question to choose the setting or something...
Steven -
You were right on. I would also add that this fixed my iPad Air doing airplay as well. The iPad did not fill the TV top to bottom. Now it does (still has a left/right border). Perfect.
Excelent
I was having similar issues. In the end, a combination of switching HDMI ports (to the one labelled 'computer' - duh!), and Steven's suggestion to switch 'Adjust for Airplay Overscan' did it for me. Just adjusting for overscan alone or switching the port alone didn't do it. I put this out there in case this saves anyone else some time (as I've spent ages on this)!

Ahhh, thanks OP, thanks Steven, and thanks the internet. Another problem solved.
Not so much thanks to Apple for defaulting an option that meant I had a 2" border around my airplay image, but thanks for including an option to turn that 'feature' off.
Nice.
