I have put together 12 monitor system & everything seems to be working fine except I need help detecting & identifying & managing 12 monitors & get them to do what I built it for. I am running windows-7 ( 64 bit ) & other specs are as follows. It is a Dell Workstation T -7500 which I upgraded with ATI FirePro 2460 graphics cards. Intel Xeon E5645 @ 2.4 GHz 3 ATI FirePro 2460 Video cards each with 4 output ports. I2 GB DRR3 ECC RAM 12 Identical Dell ( U2412M ) 24 inch monitors ( 1920X1200 ) Here is what I have now & what I would like it to do. I have arranged 12 monitors in two rows of six each. Windows-7 identifies 12 monitors but labels only 10 monitors with numbers 1 to 10 & shows two monitors without numbers in display property. They are given random 12 numbers in each row & I canât rearrange them starting with number one in Bottom right corner & number 12 in Top right corner. I tried rearranging in display property but it won't work. I am having trouble locating mouse in each monitor. I would like to point the mouse cursor in any monitor at will which I canât do now. I would like to detach & drag 12 windows from main application to the desired monitor. I am willing to Buy any special multi monitor software if you guys know that can do the job. Thanks much in advance.
