Image Alignment
Whenever a single image is spanned across three screens, the gap between the screens comes into play. Typically a user would adjust monitor images so that the images end at the edge of each screen, ensuring everything your computer thinks is visible is actually visible. However, with an image spanned across three screens, this can make diagonal lines appear discontinuous and wrong:
To eliminate these discontinuities, it is possible to adjust each monitor image so that enough of the image is off of the screen and is “behind” the monitor frames. This provides a fluid image that seamlessly transitions from one screen to the next:
The problem with making these adjustments is that you are hiding potentially useful information. For example, in Strike Fighters you wind up clipping the info box, and when you go back to your desktop, say goodbye to your scroll bars and whatever else might be “behind” the monitor frames (it would be easy to lose an entire column of icons in my case):
