English Amiga Board - View Single Post - What is the real Amiga Maximum overscan in PAL?

In the include files there's four standard overscan modes listed.

#define OSCAN_TEXT /*entirely visible*/
#define OSCAN_STANDARD /*just past edges*/
#define OSCAN_MAX /*as much as possible*/
#define OSCAN_VIDEO /*even more than is possible*/

OSCAN_TEXT corrisponse to the 'text' setting in overscan prefs.
OSCAN_STANDARD corrisponse to the 'graphics' setting in overscan prefs.
OSCAN_MAX PAL=724x566 NTSC=724x482
OSCAN_VIDEO PAL=736x566 NTSC=736x482

These are the actual display sizes I got when I opened the screens using the above overscan modes. I suspect OSCAN_VIDEO is the biggest the chip set is capable of since it's bigger then what is possible, I could be wrong.
