My gfx card and monitors work beautifully under OSX and Linux. The problem is only MOS related.
I*know. That's exactly what happened to a friend with his peg2.
And regarding the proposed vga cable fix, it is not a good solution either, just read the thread.
I tested it on my friends Peg2 and it solved the problem. But if you don't like the idea you can do other things:
a) rename sys:morphos/libs/ddc.library to anything else. That will disable DDC completely, it's the most "rude" solution.
b) connect your crt, save some basic 31Khz modes you know that will work in the TFT monitor and once it's more or less configured copy env:cybergraphx/RadeonMonitor to envarc:cybergraphx it should leave there the settings. It's the best choice because OS updates will respect your settings, otherwise you will have to rename ddc.library each time you update the OS.
Then, boot with the TFT monitor and configure properly the screenmodes.
I erased MOS from my HDD and installed OSX untill display problems get fixed. It is really annoying to resort to use an old CRT monitor in this age, just to get MOS display its Ambient screen.
You don't have to use a CRT monitor. DDC works most of times, you are the 2nd person I know with problems. There are workarounds. I didn't read any post from you at MorphZone or morphos mailing list so your questions passed unnoticed, you deleted it too fast IMHO.
I hope you can configure MorphOS properly, I deleted OSX from my Mac Mini and I'm very happy with MorphOS
