Hey,
I display my photographs on a HDTV using the WD TV Live Hub as the source of the files. Photos in landscape format look awesome, but portrait ones less so because they take up only a small section of the screen. I’ve overcome this by displaying 2 or even 3 photos at same time.
It just takes some basic photo editing SW skills and time.
