Welcome to the Apple Community.
There are hardware converters that will convert HDMI to various other types of output, however there are some issues with doing so that you should be aware of.
Resolution and aspect ratio
I'm not aware of any converters that will scale the output from the Apple TV, any TV or projectoe which is used will need to be widescreen and support resolutions of 720p or 480p.

Winston pretty much nailed it.
Sadly, it just seems like this particular projector and the Apple TV aren't a good match for one another. Sorry :-/
