1680 x 1050 on iBook G4 (ATI Radeon 9550

[cporter1959]

I have an iBook G4 with an ATI Radeon 9550 card with Screen Spanning Doctor installed. I recently purchased a 22 in monitor with native res 1680 x 1050. When I open up the display preferences, I don't see this resolution. Someone suggested SwitchResX, but I have no idea how to use it. Is it possible to get this resolution with my iBook, or should I return the monitor?

My wild guess is that it's the iBook G4 (early 2005) which would have these specs. http://support.apple.com/kb/SP43

Display
Choice of built-in 12.1-inch or 14.1-inch (diagonal) TFT XGA active-matrix display
Support for millions of colors at 1024 x 768 pixel resolution
Support for resolution scaling to 800 x 600 pixel and 640 x 480 pixel resolution with millions of colors
Graphics support
ATI Mobility Radeon 9550 graphics processor with 32MB of dedicated video memory and AGP 4X support

I haven't tested any available hacks but at least without those you would be limited to that resolution - and mirroring the screens. The non-supported resolutions aren't showing in sys prefs.

Thanks...I have Screen Spanning Doctor, so I can use extended screen and other resolutions, which is why this is so perplexing. Currently, I have my resolution set to 1600 X 1024, so everything is blurry. I guess I will return the monitor.
