Custom Resolution Utility (CRU)

[Foobar]

Hullo!

Thanks for a great utility. I've used it successfully on several monitors.

Now I'm trying to use it on a Samsung S27C750P. This has been confirmed by reviewer (NCX over at WeCraveGames forums) to do 75hz (Nvidia driver settings with standard timings).
However I cannot reproduce it on a ATI HD3650 with catalyst 12.6. The monitor input seems very sensitive to input timing. Whenever I go over 71hz and stay under 165mhz the screen image gets distorted in a way that is typical for timing issues.

Supposedly this monitor can do over 165mhz but all custom resolutions I make that have bandwidth over 165 wont show up in the refresh rate menus. I have tried the pixel clock patcher, but they still will not show up and I cannot select them.

Any ideas?
