ATI Radeon X1900 XT driver for MacPro

I put an ATI Radeon X1900 XT for MacPro in my 2 x 3 GHz MacPro. It displays only 1280 x 800 on my 30" Cinema. Do I need to install a driver, and if so, where to get the driver since card did not come with CD and AMD site has not posted a driver?

2 x 3 GHz MacPro Mac OS X (10.4.8)

Where did you get the card? Was it specifically meant to be installed in a Mac Pro? The Apple-supplied card features two dual-link DVI ports, both able to drive a 30" Cinema Display at full resolution. There may be other variants of the card meant for other markets that only have one dual-link port, or just two single-link ports.

zspike --

You don't need drivers -- they're built in to the OS. However, it would be nice to use the ATi displays panel, so you can turn on various app-specific speed settings and features like full-screen antialiasing.

Now, version 4.5.9 of ATi Displays is a Universal Binary, but ATi in their infinite wisdom have made it so that it WILL NOT install on a Mac Pro, only a G5.

But there's a way around this:

Have a look at post No. 8. Simply put the displays.app in your /Applications/Utilities folder, and run it from there. Runs no problem. I couldn't get the Prefs Pane to work, but all that does is launch the Displays.app

Have fun!
