iX3D Twin Turbo resolution hacking?

[mat_r74]

Hi to everyone,
this is my first post. :b&w:
I have an old beige G3 with an IX3D TwinTurbo card.

Now it can handle an 1920x1080 image (displayed not correctly on my monitor)

and a 1920x1200 image (compressed) but not a 1680x1050 image.
Is there no chance to have a hack for the 1680x1050 resolution?
I have tried your 9600 driver but (obviously) it doesn't work for my card.
The Apple IX3D Graphics Accelerator extension (included in the System 9.2.1)  looks like very similar.
Could you help me?
Thank you in advance.

Matteo

As you're asking about a different video card, I've moved your comment to a new thread from the old one, mat_r74.  I think you'll have more chance of some useful replies that way.

Thank you very much!
