How do I get the Catalyst drivers to allow > 1600x1200?

My new All-in-wonder 9700 is acting wierd, even with the latest drivers installed.

To start with, if "Hide modes this monitor can't display" is checked, it gives 1600x1200 as the highest option, which is wrong -- on my Geforce2 GTS 2048x1536 is available even with that box checked, as the monitor will display that (and higher) perfectly fine, in fact one of the built-in recognized modes is 1880x1440, and the max resolution powerstrip reports that it reads from the monitor itself, and from the windows registry (they match) is 2984x1680. The monitor is definately recognized, in fact it even lets me set the geometry and other OSD settings through the USB port.

If I uncheck that checkbox, the higher options become available on the resolution slider, BUT, when I pick one it doesn't really switch to it, it makes the desktop the new resolution, and the screen scrolls when you move the mouse showing only a 1600x1200 region at a time.

When I set custom timings for 1920x1440 to try to force it in with powerstrip, I still get this effect - the video card seems to override powerstrip's settings.

What is the point of a card with a 400MHz RAMDAC if the highest mode the drivers allow is around 225MHz?

Both 32 and 64 bit modes have this limitation.

Go to the display section of your control panel. Untick the DDC button and manually set the resolution and refresh rate drop-down menus to the highest values your monitor supports.
