Short: REMOVES Overscan limits, V1.0, 23.12.95 Author: Thomas Krafzik Uploader: Martin Schulze (schulze@phil.uni-sb.de) Type: util/boot Kurz: beseitigt Overscangrenzen, V1.0, 23.12.95 Requires: OS 2.1 or higher (only tested with 3.0 and 3.1 on an Amiga4000/030) DISCLAIMER: -------------------------------------------------------------------------- This is FREEWARE. Distribution on Aminet and AminetCDs is always ok. Distribution by Fred Fish is always ok. Distribution on MeetingPearlsCDs is always ok.

Have you ever changed your monitor driver with MonEd or the like ? Perhaps you have noticed that if you increased vertical/horizontal resolution about the overscan limit you can have a larger view as your max overscan. But if you move the mouse beyond these overscan, the screen scrolls (if you have autoscroll on). If you haven't autoscroll on, the mouse stops at max overscan ! Silly, eh ? So, increase the max/video overscan with this program and your screen scrolls no longer. It can change the overscan settings for video, max, and nominal overscan. So you can, e.g. change the vertical overscan on the EURO36 monitor. Template: PatchOverscan ID=MODEID/K/A O=OVERSCAN/K/A MINX/N/A MAXX/N/A MINY/N/A MAXY/N/A ID: a monitor id, like in include:graphics/modeid.h O: overscan type, one of N (Nominal) M (Maximal) V (Video) MINX: lower horizontal bound for overscan rectangle (can be < 0) MINY: lower vertical bound for overscan rectangle (can be < 0) MAXX: upper horizontal bound for overscan rectangle (must be > MINX) MAXY: upper veertical bound for overscan rectangle (must be > MINY) Example: PatchOverscan ID=79000 O=M 0 0 719 299 This gives you a max overscan of 720 * 300 for the "EURO36: HighRes" screenmode. Start "Prefs/Overscan", select "EURO36" and now you can edit between 640 * 200 and 720 * 300 pixels. Best place to start this program is in your s:startup-sequence before IPrefs but after you have mounted your monitor drivers. (obviously) If this doesn't work, try it additionally after IPrefs ... NOTE: This is a HACK and will not work for standard PAL and NTSC monitor drivers, because they don't seem to build a fully featured entry in the display database. Tech: This program uses an undocumented function of the AmigaOS, so don't expect it to work with future versions of the OS.
