My method for getting a screen saver to be full sized.
I took a 4912 x 3264 photo and stretched it to 5760 x 3840 on my computer. These are the maximum specs the radio would accept. I then selected to have the picture set in widescreen (set this during the picture download process). I found that having the screen set to widescreen/normal in the settings had no effect, I leave it in widescreen anyway.
I have already heard "there is no way the screen is 5760 x 3840" ... well it works so
