In Project Options -- Screen, the aspect ratio of the slide has to be specified, i.e. 4:3 or 16:9, etc. to suit the corresponding display ratio of the PC monitor. The problem is that the slideshow may sometimes need to be displayed on monitors of different ratios. I found that when I set the ratio of the slide at 4:3 and display it on a 16:9 monitor, 4 black strips appear around all sides of the slide whereas I expect that only 2 black strips appear at the left and right sides. Similarly, when I set the ratio of the slide at 16:9 and display it on a 4:3 monitor, 4 black strips appear around all sides of the slide whereas I expect that only 2 black strips appear at the top and bottom sides. Could the administrator or any member help to fixt the above problems in PicturestoEXE 5.XX, which do not occur in version 4.xx?[size="4"]
