Refresh Rate

I am using this product that uses DisplayLink technology and I have a problem with it.

I have a CRT, a Sony Multiscan20se, and when I plug it directly into my PC, I do use a GeForce GTX 260, I can choose resolutions like 1280x1024 together with a refresh rate of 75 Hz. But when I plug the CRT into the above linked USB to DVI (with the help of a DVI->VGA adapter) I can't choose anything above 60 Hz for any resolution. With one exception, when I use 800x600 I can use 75 Hz. Where this exception comes from is a question for me too.

I have tried quite anything that is available in the net about forcing a gpu to show a specific screen refresh rate including editing the EDID but nothing has helped so far.

Please help!
