I have an Optima GT 1090 HDR set at a 4:3 aspect ratio and a Carl’s screen also at a 4:3 aspect ratio and running a sky track from an iPad. when I use the projector I can’t get the image to fill the whole screen without zooming way out (-5) and placing the projector way beyond where projector central throw calculator says to go, even then the image doesn’t feel the full screen. any recommendations?
