My mom complained about a problem recently, where Zuma Blitz didn’t fill her entire screen when she opened it. It was set to full screen, but wouldn’t.
When I looked this up, it looks like everybody has a similar problem with other games. Descriptions were like, “There are black borders around my game” or “my game only does full screen partially” and such.
I found one post by CndnPhoenix at the Big Fish forums–it said to look up “Fullscreen Aspect” or such for your video settings.
b) to fill the screen
c) to keep the original aspect of the application.
With C being the “default.”
That means that the games that come with a smaller (squarer) resolution, will be seen that way, instead of stretched to fill the screen. (Unless, of course, the game adds this feature/option, themselves.) So what needs to be done is to change the ‘default aspect ratio’ of your video card.
