But where do the underlying modelines come from? Does the converter
provide them? I don't know the Hsync and Vrefresh limmits, but this is
a modeline from one of my panels, which comes the same with my CRT's.
So I guess it's a vesa mode:

Modeline "1024x768x60.0"   65.00  1024 1048 1184 1344   768  771  777  806 -hsync -vsync #(48.4 kHz e)

You can try adding it to your monitor section.
