dual video problem

[mdbusa]

Hello

I am trying to set up dula display--It works except that the colors on both screens are wrong and there is some weird streaking etc.. both screens have the same problems

With one display it is normal with no problems.

monitors are IBM P76
cpu IBM Intelistation Pro M

video is ATI Fire GL4 Video Accelerator

I think i have the right drivers but this is an old system-it is my first expeience with dual display do maybe there are some settings that I am unfamiialr with.

thanks for any help
