Running a dual display using Radeon 9800 Pro

[NewSc2]

I'm running a Radeon 9800 pro, with pretty recent drivers (reformatted this computer 1 month ago, newly installed everything).

I just bought a Dell 20" LCD screen, and it works perfectly with the video card. I want to use my old 21" CRT alongside for dual display, but it's not really working.

First I couldn't get anything on the 2nd screen. Then I installed the ATI Control Center and when I booted up, I saw the bootup screen on both monitors.

Now in Windows -> Display Properties I'm still stuck where I was before. I will click "Extend my desktop onto this monitor" and then "Apply" or "OK" and the monitor will just go back to being grayed out/disabled. No image pops up.

On a side note, I can't see the ATI Control Panel when I click on ATI properties.

Any help?

I know it will work as I was doing it as of a week ago on a 9800 Pro. When you first power on your PC you should see the BIOS info on both screens. If you don't then something is wrong with the hardware. I assume you've swapped monitors and the problem changed with the monitors?

I sounds like the drivers are hosed. I believe ATI or somebody has a utility to delete all traces of the drivers. Uninstall and wipe the drivers then try again. It sounds odd but make sure you don't also have nvidia drivers installed. ATI and Nvidia drivers don't play nice with each other.

It'll definately work, I was using dual monitors on a 9800pro up until Monday.

In the CCC, go to Display Manager I think it was, and then you can configure whether it uses the second screen. That's how I did it. If you don't have Catalyst Control Center installed, that may be the problem.

You can see the BIOS because that just runs straigt through the hardware really, once windows starts up, it's over to softwrae/drivers and stuff, I dno how to describe it, but yeah, you'll see the BIOS unless the hardware is broken.

I've had problems getting my 9700 working with 2 displays. Sometimes bios shows on both screens, usually it doesn't.

Eventually it just kind of started working, although ATI's control panel makes it a lot harder then it ought to be.
