Lo-Res sync problem
I've got a weird problem on my 1200 which is causing the screen to mess up when using what I assume is a Lo-Res screen mode.
If I boot from floppy, all is fine, however if I boot from my HD using PAL Hi-Res, and THEN use a prog such as SysInfo or D-Paint. The screen goes 'squiggly'...... If I boot the same progs from their floppys they work just fine though, so not sure where there problem lies. Any ideas? Last edited by XimeR; 10 September 2010 at 15:47. |

Monitor driver in DEVS: corrupt somehow? How about NTSC lores modes, do they work? Booting with no startup-sequence and doing loadwb from the shell produce any kind of different result?

Does not need to be corrupted. Just wrong drivers can cause this already. Looks like using DblPAL or DblNTSC on a TV. If anything but NTSC or PAL is in Devs/DosDrivers, move it out of there.
Also run Prefs/IControl and disable "mode promotion". Could also be caused by using an NTSC Amiga on a PAL-only TV or vice versa. At least SysInfo does not specify a specific monitor ID but uses the default mode which defaults to the Amiga's norm, no matter what drivers are present in Devs/DosDrivers. |

Thanks fellas, it's working perfectly now
The Monitors dir was filled with all sorts. I've left PAL in there and moved the rest to storage. I should have known this, but after all these years of being stuck on a PC, it seems I've even forgotten the basics. I've also unchecked 'mode protection' as advised, but out of interest, what does that do? Thanks a lot. Marc. |

It's mode promotion, not protection.
If DblPAL is in Devs/Monitors and the Workbench screen is in DblPAL mode and an application requests to open a PAL screen, then the application's screen is opened in DblPAL instead. Same for NTSC and DblNTSC. |
