I have Installed a FirePro w4100 (P\N: 100-505817) see here in a Desktop running Win 10. I can only get two of the three monitors to work, Windows will recognize the third display but wont let me "Extend" it unless I disable another one. The mother board has integrated graphics which I have turned on and off in BIOS but wont allow the graphics card to show all three monitors at the same time.
They are all connected using a Mini DisplayPort to DVI Cable see here.
The Monitors I'm using are: Viewsonic VA926g , Viewsonic VG39Sm, NEC LCD193WXM
I installed the Drivers that came on the disk and after downloaded the latest Drivers from AMD I even reinstalled the Drivers and let the FirePro Control Center update itself
Driver Packaging Version 15.30.1025.1001-151129b-297237E
I've searched the web to try and find a solution but nothing anyone suggests has worked I'm not sure if its the video card drivers or Windows 10, I have done this installation on three other desktops running Windows 7 and everything worked fine.I'm not sure if this is a driver issue or a Windows 10 problem should I be in the Microsoft forums instead of here?
If this cant be solved can anyone suggest a video card that WILL work with Windows 10 and at least three monitors.
Only two "legacy" displays (DVI, HDMI, VGA) are supported by the GPU. If connecting to more than two of these, then the third/fourth must be connected via active adapter such as UltraAV® Mini DisplayPort to DVI-D Active Single-Link Adapter – Accell
