"Signal Out of Range" message on LCD - but showing 15khz picture!

[dandelion]

Hi all,

Have just picked up an aging LCD monitor, a Medion 7514 model. I had little hope of it being able to display native 15khz Amiga output but thought i'd give it a try anyway. On startup I was suprised / overjoyed to see the purple screen and floppy disk animation! But, a floating message soon appeared saying "Signal Out of Range : Set Monitor to 1024x768 60hz". There seems to be no way to get rid of this. Does this mean that the monitor can't display this screenmode safely, and on most monitors this would be blanked out? Can I alter the settings somehow to get rid of this error message? Also - when this error message is displayed I can't access the monitor set up controls. None of the buttons work. I've plugged it into a standard SVGA outputting machine and it works fine, and I CAN access the set up pages. I've tried selecting a 60hz mode (well, it says this is already selected), but it makes no difference when trying again with the Amy.

Any ideas, experiences related to this? Am I damaging the monitor in getting it to display something so lowly as a 15khz display?

Cheers

Actually - thinking about it!! I think there is an "OSD" option in the setup menu. Will play with that this evening.

Okay, well. Got home, plugged the monitor into my Acorn (which gives SVGA out) to access the on-screen display. The "OSD" option within the menu allows you to control the horizontal and vertical position of the OSD menu, but not warning boxes it seems. When I plug the Amiga back in, it's just as before. The only options I don't understand are "clock" and "phase" which i'd think have some low-level frequency adjusting ability. Anything of value there? Otherwise I think it's going to be 31khz only
