Hi All - question from a graphics newby.


I have installed a Firepro 2460 in a win7 pro 64 bit machine.

I was trying to do a quick and easy solution for a 2x2 display wall which will eventually be driving 4 identical Large HDTVs.


To test out the theory I have attached 2 x LG W2242P monitors as Displays 1&2.  These consistently work fine.

When I try to attach 2 x ACER V243HL monitors as Displays 3 & 4, I can only get one or the other to operate.

The 2 ACER monitors have exactly the same model numbers on the compliance plates.

All of the monitors are attached using the supplied Mini-DP to DVI cables.


From the windows screen resolution setup I have extended the 3 displays.  When I try to extend the display to screen 4

I get the informative "Unable to save display settings" message box.  If I disable screen 3 then I can extend to screen 4 ok.


From Catalyst Control Centre I get the message "To extend the desktop, a desktop or display must be disabled".


Any suggestions gratefully accepted.
