I had the same card and returned it. I had a lot of problems with it and trying to use the pci card with the existing ATI card that came with my dell. So thinking it was a driver problem with too many cards running, I decided to just get a dual monitor card for that AGP slot. For some reason I stuck with the ATI line of cards. I got the 9000 radeon pro. Still had little problems so I reformatted the computer to get a clean install of everything. I am still having weird little issues. Basically I will never purchase an ATI card again for running dual monitors. The pictures are not as clear as they could be, and there are still a bunch of annoying problems occuring.
once again, regarding that yellow picture, i had the same problem, it was just bad connections with the cable. i played with the cable a bit and it got fixed. they told me the same at the lab. you're best off asking IT support groups at Usenet (comp.sys.ibm.pc.hardware.video or comp.sys.ibm.pc.hardware.misc) use groups.google.com cheers 50
I have to tell that I bought the Dell GX260 with ATI RADEON VE Dual Display AGP with 2*21” monitor and it was fantastic (the first Card)
