Ok! So, I flipped the magic switch and voila, it works. I did notice though, that any interlaced resolution I chose has an absolutely horrible re-fresh rate that hurts my eyes. All the non-Interlaced resolutions are perfectly fine, except that they are not the resolution sizes that I want to use.
Shouldn't this monitor handle the different resolutions? Perhaps I simply need to run some sort of program to make things right?
My Amiga is supposed to be a NTSC version. The monitor was purchased in the US.
The different options I seem to have are:
640X400 Interlaced
640X200
320X400 Interlaced
320X200
1280X400 Interlaced
1280X200
