Forums -> Multiple monitors -> Radeon HD 4870 X2

I’m running UltraMon 3.03 with a VisionTek Radeon HD 4870X2 video card on a windows XP workstation.
I use UltraMon to clone my desktop from my 30 inch dell monitor to my 12 inch Wacom Cintiq tablet. This worked great with an ATI 4850 card. UltraMon displayed a perfect 2500X1600 resolution on my large monitor and mirrored it to my 1200X800 Wacom tablet with scaling.

After I installed my new card from VisionTek I got the following error:
CrossFireX is currently enabled. Before you can enable an extended desktop or reassign the primary display you need to disable CrossFireX. Please recheck your CrossFireX status.

I get the same error message when I try to clone the display in the Display Settings in Control Panel.

I can clone a display through ATI’s Catalyst Control Center but with their software I’m forced to use the display resolution of the smallest screen. In this case 1200X800 on a 30 inch monitor.

Any suggestions?

Cheers

Jerry
