First it can not switch
on the go from NTSC to Pal. If your amiga display can not due that then why use it?
Second it does not display certain programs or views unless I load the WB with original
Chipset, weird. Or if I try looking at images from a program like VT after a few displays it
stops being able to display the images. Just says signal not detected. I switched monitors
to my Commodore 1950 and got basically the same results.
Do you have several monitor files in your DEVS:Monitors drawer? Maybe your programs try to open "best fit" displays to some monitor drivers which won't work on your setup?
In any case you should edit Indivision display settings for _each_ monitor separately with its config too. Check all modes you have in use, and think twice if you need to keep them in use.
