Of course the VGA monitor does not even support 200-line modes, so it is obvious from the context that this is about VGA so the 320x200 pixel modes are double-pixeled and double-scanned, so the monitor will regard them all as same 640x400 or 720x400 mode as they only differ in their timing by about 4 PPM. | |
