The "black" is the monitor being driven beyond it's spec in either
vertical or horitizontal or both.

For it to work, you'll need a proper mode line that can be stolen from
some other Linux system  via a google search or by downloading puppy
linux and using that to work out what X is doing.

With X and gfx, /var/log/Xorg.0.log is your friend.  Especially when
used with a google search on the error message.
