More than 3 years later, I'd like to know as well. It's not possible to view a photo off the micro SD card in full screen mode. You get the OSD surrounding the photo on all 4 sides. The resolution of the photo makes no difference. What was the point of 1920 x 1080 screens if most of that resolution is taken up by OSD ?
You cannot display a 1920 x 1080 pixel image in full screen mode. WTF is that about ?
