It will be preferable to most PLP users to game with visible image as a perfectly lined-up rectangle (keeping black margins on tall sides. It is clean this way & a better use of PC resources (as peripheral vision is of less value). While surf/work remains full unmatched heights). So corrective margins on side screens is a great feature (top or bottom). But the filling option is great to have. Particularly if center screen is shorter than sides (not recommended). Looking forward to trying it all out.
