Hi I am hoping someone may be able to help or perhaps have same issue.

I have purchased a Mbox android TV with jellybeans and am using it through an optoma hd 33 projector. The home screens desktop etc display correctly in the right size as does the kodi interface. However when I open a stream the picture is completely zoomed in. Any ideas on how to correct this or is it just not compatible with a projector. Many thanks
