Apple Event: May 7th at 7 am PT
When I airplay my macbook (15 inch)'s display over to my Apple TV 3rd Generation on 720p 60hz, almost 1/3 of the whole screen is cut off. Changing the aspect ratio doesn't help either and neither does overscan correction. It just seems zoomed in on the top left hand portion of the screen.
MacBook Pro, OS X Mountain Lion
Also, I just tried unchecking the Overscan Correction and the display went out for a second, and when it came back the Airplay was using the full screen and not just a tiny 1/4 or 1/3 of the screen. I even checked the Overscan Correction box and it went blank again but came back again using the entire screen. In my case it seemed to be an issue with resetting the system, I would try restarting your computer ultimately.
I have the same issue. Full screen mirroring only works with "auto" display selection but not with 720p.
Unfortunately I have an HDMI switch between my ApplyTV and TV. It only works if I force the signal to 720p but the airplay mirroring only works properly (full screen) with automatic (which sets 1080p).
Nasty conundrum.
Basically, this is a problem of TV not the apple tv. Every TV overscans image by default to adapt various sources. If you want to have exact-fit picture, you should turn off the overscan function on your TV.
It depends on TV makes, models that how to turn it off. For LG, they even call it as 'Justscan'.
Getting the same problm I think.
The Airplay works and connects fine, I installed into our office for management to do presentations, issue is.
The Airplay screen is full screen, fine.
Play video from the Ipad to Airplay, Also fine, fills the screen. but when I turn on mirroring, it is only about 2/3 size of the screen, doesnt fill it, this is when I hold the unit in Landscape mode of course, if I turn it to portrait it flips it correctly but does fill the hieght of the screen.
OPne other issue I find is, I have Friends using an Iphone 5 with IOS6 and they can turn on the airplay, but the mirroring option is not available, so he can only present photos or Audio.
A few fixes needed I think.
I tried the options mentioned above, such as Overscan, different resolutions, now set to auto, and no options available in the ipad I can find. so any ideas any one?

Sadly no,
You may want to check your projector one last time to see if there are any overscan settings or what not. Chances are though, Apple needs to update their Airplay. It's something newer for Apple so there are inherently kinks in the system, and I feel this issue is largely to do with Apple. But go through all the suggestions again, try restarting and checking for updates.
Good luck,

Thanks Eric, to confirm, I did re run through, as you suggested and the issue is the same, reliable like a feature, so we shall see if apple picks up this issue from here and applies a fix.
I have tried to restore my Apple TV. It worked perfectly fine the first time. However, now, I can not even see a thing. The wifi shuts down as soon as I click the Apple TV AirPlay mirroring function. It's not just my wifi, it's the wifi network. It's shut down for a temporary amount of time
I have just expirenced the same problem. Resolved this by changing the "Adjust for airplay overscan" option in the audio & Video settings from the Apple TV. Works perfectly now 🙂
Man! Turning off the over scan option solved my problem completely. Thanks a lot!
This helped me in other situation, connecting my windows 7 ultimate laptop with my imac 21.5" late 2012, as you change the imac resolution you'll get a bigger "full screen" on it, it's not the best resolution, but works.
You are my hero. This did the trick instantly.
Airplay not full screen!
