Slideshow aspect ratio in Photos App
Hi,
When starting a slideshow in Photos (be it through albums, project, with or without scale to fit and no matter the theme) I always have black empty bars on the top and bottom of the slideshow. I've come to realise that, contrary to Finder for example, the Photos app run slideshows in 16:9 aspect ratio (standard widescreen format). However, my display in 2880x1800 so more like 16:10...
My question is: can I change a setting so that the slideshow displays in proper fullscreen and not in 16:9 with black bars?
Thanks for your help, much appreciated, I've been pulling my hair out over this :)
