Usually speaking, on a Windows machine, that is a resolution thing, where the monitor, windows and the game have to all be set to the monitors "native" resolution. As an example, my desktop has on old 18" LCD, which is 1280x1024 for a 5:4 resolution, while my laptop is 1600x900, which is 16:9 ratio. So the Windows display is set to that, and my SH4 is set to that, and I lose nothing on either setting. If however, I am re-doing a mod, and have erased the Save folder, the game will default to 1024x768, a 4:3 ratio, and things will be crowded on the desktop, and missing on the laptop. You're using bootcamp, so I have no idea which is "boss" in that case, for matching screen resolutions, but SH4 needs to "match" that ratio at the least...
