Sorry if my answer is short and sweet, but 4:3 > 16:9 > 4:3 is always going to produce letter boxing and pillar boxing simultaneously. Your projector receives 720 lines of resolution, if the projector was able to zoom accordingly it could overcome the issue, but clearly it can't.

Thank you for the reply. I understand that aspect ratio issue. But since I found the setting on the Apple TV that got rid of the letter box by stretching the image, I was hoping for/ wondering about a setting that would take care of the pillar box.
Followup question: I got Apple's HDMI dongle as a backup to use in case WiFi or the internet was down, but when I use it, the iPad image on the screen is really small again, about half the size it should be. Can you tell me - is the image/data changed to 16:9 to go through the HDMI cord? Because I wasn't expecting to have the same 4:3 > 16:9 > 4:3 conversion problem with the dongle like I did with the Apple TV.
I don't know why my projector's zoom function acts the way it does. That would obviously be the quickest fix.

We are having exactly the same issue, we rolled out some 30 apple tvs to our staff and lots of them have complained the image is too small due to the odd resolution issue with the airplay function.
The apple tvs are a nightmare enough from an IT management perspective not supporting proxy servers or enterprise wifi security without this headache!

I am also having this same problem. I guess Apple wasn't thinking of us teachers who use 4:3 LCD projectors in class and want Airplay too.
My guess is the problem is a combination of the way Apple TV functions and the iPad functions.
When I connect my iPad through the HDMI doggle to an 4:3 HDMI projector, mirroring still produces a small 4:3 image in the middle. So without the Apple TV in the picture, going through the HDMI connector doesn't produce our desired result (a full 4:3 image covering the whole image area). When I connect my iPad to the same projector, but go through a VGA doggle, then everything works fine. So this seems to indicate that somehow the iPad is designed to assume a 16:9 display when outputting through HDMI and a 4:3 display when outputting through VGA. I have not completely tested to see if this hypothesis is true yet (i.e. try the reverse of connecting a 16:9 VGA display through a VGA doggle).
Anyway, I was surprised that I encountered this problem because Apple TV has been out for a while and I couldn't imagine I was the only teacher in the world wanting to use the Apple TV in a classroom that has the traditional 4:3 LCD projector.

Same problem here at our school with our 7 AppleTVs. It's frustrating because, as you said with a VGA adapter it works just fine. As all of us have SmartBoards, we are confined to the 4x3 aspect ratio. Considering the iPad is 4x3 and the AppleTV can do 4x3, it is ludicrous that an option does not exist to make this work.

I too am having the same issue. I'm trying to use keynote and other apps to mirror to my church congregation as a part of my sermon talk. I'm also unwilling to use cables when I can go wirelessly through my Apple TV. Praying for a solution to emerge soon!

After some more investigation, the only solution that I've found is that some LCD projectors have the ability to zoom in on the center portion of the display (i.e. make the smaller 4:3 image in the center of the screen that we get going through Apple TV) and make it fill the whole screen. This setting is sometimes in the place that can adjust the "Aspect", and you need to select the one that is called "Wide Zoom", "Wide" or just "Zoom". Each projector is a little different (I've looked at three different projectors that we have at school), and ony the newer ones seem to have this feature.
If your projector can do this, it works well for mirroring your display, but when you play a 16:9 video on your iPad through Apple TV, because it seems to always assume you are using an HD/16:9 screen, it thinks it is "smart" by then playing your video using the full 16:9 screen. But if you have done the "Zoom" on your projector, then the left and right portions of the video will get cut off. You will need to undo the "Zoom" and return your projector to its normal setting in order to see the full width of the video.
Let's all pray that Apple will eventually get this right and let the iPad/Apple TV combination work well with both 16:9 and 4:3 displays/screens/projectors.

We have the same problem, and not only with ipads. Macbook Air is doing something similar. it can only use airplay with 1080 and 720 resolution, so the image is squeezed on a 4:3 projector. We use AppleTV 3 and Mountain Lion OS. We use ATVPRO from Kanex.
Apple must get its act together and fix this, they promise gold and green forests, but nothing works.

AppleTV is designed to output HD in 16x9 and the requirements for the AppleTV state an HDMI connection to an HDTV.
The way I see it you are trying to put square pegs in round holes and have two options.
1. get an HDTV or HDTV projector that displays 16x9 and has an HDMI connector
2. replace the AppleTV with a device that can display 4x3 to your 4x3 TV or projector.

If Apple TV is designed for 16:9, why can I set the TV resolution on Apple TV 1024 * 768? But it does not work as a MacBook changes the resolution to 720p no matter if Apple TV is set to 720P or 1024 * 768

thanks for your older post about using a thinner cable so that the MacBook Air would display on the outside monitor. It worked for me, and I had to pass it on to the Apple Genius bar so that Apple could figure what is up and provide more "fixing". Have you learned more about the issue of the MBA?
(Sorry I could not figure how to post this to your actual comments about the MBA.)

I had a similar problem and worked out that switching off the "Overscan-Mode" was the solution...

Thank you andreabaer for posting this question.
I am experiencing a similar problem with AirPlay only, not with straight Apple TV nor with the iPad VGA dongle.
Apple TV -> VGA monitor -- FINE. For example, the Apple TV home screen fills up my VGA monitor, although things are stretched vertically (how do I fix that?).
iPad2 -> VGA monitor (via dongle) -- FINE. iPad image maximally fills the screen, without distortion. That is, when the iPad is displaying in landscape, it fills the screen completely; in portrait, it uses the full height with appropriate black margins
iPad2 -> Apple TV -> VGA monitor (via AirPlay) -- BAD. iPad image is squished horizontally, so that there are large black margins on the L & R sides (pillarboxed), and smaller margins top & bottom.
I have tried turning AirPlay Overscan on and off and tried various resolutions. Provided I can see any image at all, nothing changes.

Was there a fix for this without purchasing a new projector?
