Some visitors may use standard monitors and others may use widescreen monitors.

A standard monitor may have 1024x768, 1280x1024, 800x600, or the older 640x480; or some higher resolutions.

A widescreen monitor can have 1280x768, 1440x900, or higher resolutions.

A standard 1280x1024 and a widescreen 1280x768 could have the same centering left to right; however, top to bottom would not work for one or the other.

This really doesn't make sense. The browser places the site in the centre of the open window, regardless of how large the window is re-sized to. This is because the placement is dynamic based on the window width which is constanty recalculated. There must be a way through HTML to dynamically place the site in the centre dynamically regardless of window height. I've seen this done without margins. I'll have to peek into the HTML page code.

UPDATE: this can be done through CSS code, see this discussion.
