There is a setting to change the size of the HUD. I run triple monitors, and if this did not exist, it would spread the HUD over the three screens. The HUD adjustment setting allows me to pull the left and right sides in so it all fits on the center (main) screen. It also allows you to squeeze the HUD into smaller space if you wanted it to take up less room if you run one screen. If there's a MFD dimension change, that's something I haven't seen.
