Playing Hoopla movie's on iPad 4

On my husband's iPad 2, we are able to play Hoopla movies on our Apple TV (using AirPlay and mirroring) with no problems, however if we try to use my iPad 4, all movies are fuzzy. We have compare all settings on both devices and they are the same. If I play a Hoopla movie on my iPad4 screen only, it works just fine, very clear, not fuzzy at all.

Any help would really be appreciated. Thanks
