Just wondering if anyone else has noticed a thin border down one side of the game area when playing vertical games? (noticeable in DoDonPachi to be particular)
I'm using a 60cm TV, MAME v110, and a NVidia GeForce 7600GS using component output, constantly 720 x 576 @ 60Hz.
It's no big deal I guess, just annoying. It seams to be *just* outside the game area - so a screenshot won't pick it up. Here's my crude attemp at photography... This is the DoDonPachi copyright screen.

Does anyone know what's causing this line? It's not my TV ghosting obviously, because as seen in the photos it's happening even when black. Is it MAME?
