3d trouble

When I play a 3d movie (named FILENAME-3d_sbs.avi) Kodi sees it as a 3d file and asks how to display the menu. If I select “same as movie” then the menu is displayed as side-by-side, but the movie is displayed as four screens instead of two. If I select “2d” then the movie plays as two screens like it should, but the menu is all katiwompus. Also, my projector doesn’t automatically recognize that a 3d film is being played, so I have to manually turn 3d on. It does detect 3d blu-rays though…

Maybe I am doing something wrong? Any help would be great. Thanks.
