I purchased and installed a WX 4100 display card (with 4 display ports) + cables to drive 3 monitors.
Windows (10) shows 3 with only the first 2 enabled (they work fine as 2).
I have installed the latest AMD drivers.
The AMD Settings program only shows two monitors.
When I try the Eyefinity setup within the above programs I old get choice of 2 x 1 (never 3 x 1). If I proceed to the next step ... all three of the monitor names appear.
Ugh. Windows sees 3 monitors, AMD Settings sees three monitors. Why isn't eyefinity giving me the 3 monitor choice?
P.S. I see a lot of web references on how to set this up they show the use of a Catalyst Control setup program. Does this program still exist and can it help?
