<< Are you saying that before the mod 12x10@85 was much worse in image quality than 12x10@75? >>
Yes. Ghosting was much more prevalent on my 12x10@85, so much so that I had to drop the refresh rate to 75. I even bought a good, sheilded BNC cable in hopes that it would remove the ghosting. It helped, but not much. At 75hz, the ghosting was still there, but you'd really have to search for it.
After this mod, I still can't run it at 100hz, even though both the video card and monitor are rated for it. However, I can now run with pretty crisp text 12x10@85hz.
Tonight I will switch back to the SVGA cable and see if the resolution is any better than the BNC cable.
