[Solved] Installed Screensaver doesn't match up to preview (Mac OSX)


I have a Pro copy of iScreensaver [Editor: registration info removed - please don’t post your registration info on a public forum, as this will cause your registration to be deactivated] created a screensaver with a variety of images with predetermined movements that dissolve to another image at random after 5 seconds.

However, when I built the screensaver and installed it on a laptop of similar specifications, the images seemed out of proportion, and the edges of the images often passed by, revealing aesthetically unappealing blackness behind it.

Do you have any ideas what may be wrong with the screensaver? It operated fine in Preview mode.

Thank you very much for any and all assistance.

Hi Patrick,

First, please don’t post your private registration info (name or code) here on the forums, that’s equivalent to posting your password in public.

In iScreensaver, there’s a way to change the size and shape (width to height ratio) of the Preview window to match nearly any monitor size. You can preview at 25%, 50%, 100%, 150% or 200% of actual size.

In iScreensaver Designer, try setting your preview window to match the size (pixel width, height) of the computer you are having trouble with - I’m sure you will see that the behavior matches.

What do to to fix it? Unfortunately, designing video content that looks great on all screen sizes and shapes is not trivial, and in some cases it’s impossible. This is why movies and TV shows often are shown with some modification (e.g. “letterbox” (black bars) or “crop” (the sides are cut off).

If you really need an exact layout that works on different monitor shapes (different “aspect ratios”) then you may need to design a few versions of your screensaver. The most common aspect ratios are 4:3, 16:9, and 16:10, but there are others as well.

Play around with the Stretch mode settings - iScreensaver has a number of pre-made settings, as well as full custom control. See here:
