Nvidia 6600 Chipset incompatible with Sharp LL-T2020B monitor?

I built a new intel-based pc. I bought a ASUS Extreme N6600 Silencer, based on the NVIDIA GeForce 6600 chipset. I ran into the same problem with my last pc. It appears that any nvidia chipset that tries to talk to my Sharp LL-T2020B monitor won't work at any reasonable resolution. If I turn it up at all (using either the nvidia manager or the control panel) I get horrible ghosting/trails/jittery images. These are the examples I've photographed. If I turn it up to some higher settings (like the recommendd 1600x1200 the Sharp manual calls for) the monitor blacks out and says, "out of timing; 47 hz V, 48 kHz H" and I have to restart and change the resolution.

 

The sharp manual includes a list of Hsync, Vsync, and Dot frequencies for each of the display settings in Digital Mode. (I only use Digital Mode -- analog mode looks even worse, almost unreadable). However, my nVidia manager offers no way to control these settings, at best controlling a refresh rate (60, 70, 75). the higher the refresh rate, the viewer resolution options are presented.

 

On the last computer I "solved" the problem by installing a Sapphire/ATI card instead of nVidia. On this PC I was hoping tha tI could instead just adjust settings until it works, but I have run out of settings and ideas to look at. ugh.

 

I'm dying for suggested fixes.
