VGAglory: Hi,

Was hoping some wonderful person could assist. For whatever reason a good proportion of older GOG games (examples: Alien Breed, Sensible World of Soccer....), all appear as small window at center of a black bordered full screen display. It IS full screen as I am able to At-Tab out of it to a window. I currently run my desktop display at 3840x2160 with scaling set to 200% I am conciously aware that this can affect some games so I have gone into what I think is the .exe for the games and disabled scaling for these games and also set run in 640x480 but this does not seem to fix the issue. I wonder if I am applying the compatibility settings to the right exe or if Im barking up the wrong tree altogether. Any advice?

ZFR: In DOSBox conf file, make sure scaler is set to some value (like normal2x). I had this problem you describe when I set the scaler to non.

Check your graphic's card control panel (which one are you using) find an option to set scaling to "maintain aspect ratio".

Does your monitor handle its own scaling?
