ATI drivers: 1152x862@75Hz doesn't work

I just upgraded from a Radeon 8500 to a 9500 (soft 9700) this past week. Works great, but my one gripe about the drivers is that it doesn't seem to work at 1152x864@75hz. I can select the 75Hz refresh rate in the monitor settings, but it will only display at 60Hz. When I was still running my 8500 installing Rage3D tweak allowed me to override the driver limitation and display at 75Hz. Unfortunately, if I try R3DTweak with my 9500/9700, it will display at 1024x768@75Hz and operate at 1152x864 in "virtual desktop" mode.
Can anyone walk me through how to get this working properly with Rage3D Tweak or RivaTuner. Any other ideas are very welcome too. Thanks!

If you right click on the desktop and then go to properties and go to the settings tab. click on advanced and a window wit ha bunch of tabs should pop up. Click on the tab that says Displays and click on the "monitor" button I think it is...it's the button for your main display. There should be settings in there to use the DCC information. Uncheck that and put in the info taht should be in there and that should fix your problem.

I'm running Windows 2000, but I'm not seeing the same DCC setting box you describe. What OS are you using when you see that info?

What I look at the monitor tab, it displays the monitor type (which is correctly identifies). In the "monitor settings" area, I can select one of three refresh rates. I can also uncheck the box which says "hide modes that this monitor cannot display" and it'll list several refresh rates that my monitor can't do.

The weird thing is that the settings that _should_ work do show up. My monitor (a Dell 1025HTX) can do 1152x864 at 60, 70, and 75 Hz. What's strange is that regardless of the setting I choose, it always displays at 60Hz.

I understand what you're going through because I had the same problem in ME. I'm not sure what can be done if you're not running XP
because I couldn't figure it out. But, I didn't try in 2000 and it doesn't seem like you're looking in the right place.

If your card has multiple displays capability then when you go to the settings tab and click on advanced there should be a tab that says "displays"
not the "monitor" tab. After you click on the displays tab there will be the options to put it on a TV, or another monitor, etc... you click on the button that
says "monitor" and a window will pop up that lets you adjust the screen a little. In there you should be on the tab that says "attributes" and that is where the DCC info is.
I know that's how it is in XP but I don't nkow about 2k.

I'll keep poking at it, thanks for the ideas.

Anyone else have any suggestions?
