I think this is the key phrase for this topic.

As far as I can tell, it's problematic only with DVI. On Component the resolution is given by the TV Standard, and on VGA the modelines is not being messed up by the driver.

I've been reading the 1080i section of the CEA-861 standard. The modeline I'm using and the other ones showing up on the Internet seem to be close to what the standard specifies.

I also have one that is just 1 vertical line away from the standard (front porch, vertical blanking interval, and back porch total 44 instead of 45):

ModeLine "my1920x1080" 74.25 1920 2008 2052 2200 1080 1084 1094 1124 interlace +hsync +vsync
As for my black and white question, I guess this modeline is very close to answering it and it's up to the nVidia guys to fix their drivers (some time this millennium).

Thanks for the replies.
