I think this topic's fine for the list as we're moving toward using the
on-board video drivers on video cards to be able to support color X,
etc. A problem w/ seeing a monitor will mess us up too.

Is NO DISPLAY a symptom, or error message?

I bet the problem's a combination of two things. First, a lot of this
video hardware came out well before multi-sync video was the rage, so the
on-card drivers don't deal with the monitor sense info they receive
from the monitor. Second, I bet some of the cards default to 640x480
when there's a monitor of un-known type, and others default to nothing.
Thus the difference.

Or that's my guess.

Take care,
