Sounds like my old desktop, of which I can't find a picture.

I tried setting up multiple video cards, but was unsuccessful.

However, in your case, I suggest trying a different monitor, or even
specifying modelines in your X config. The monitor or video card might
not support DDC/I2C, which is how the monitor reports its capabilities
to the computer. (Or the X server might not support DDC/I2C from a
video card that old; Xorg has real problems with bitrot for drivers
for older cards)

The other possibility is to get a highish-end NVidia card with
multiple video ports on it, but using a PCI bus. I think Matrox still
sells cards like that, too.
