Hi Paul, I brought 2 numbers of miniDP to Active HDMI cables (from cablematters) and used 2 numbers of miniDP to VGA connectors(as shown in my earlier picture). The graphics card able to provide the simultaneous 4 displays now with two Viewsonic V3D231 monitors and 1 acer AL1716 monitor and 1 LG 16M65A monitor.
When I connect Viewsonic V3D231 monitor instead of acer AL1716 as a 3rd monitor, On restart all the monitors are powering up without any problem. but when I shutdown and start again none of these monitors are detecting. I need to unplug the miniDP to VGA cables(both) to detect the Active HDMI monitors and after detecting if I connect the VGA monitors it works fine again until shutdown and start.
My doubt is if I buy one more miniDP to Active HDMI cable and connect the 3rd viewsonic monitor (3 miniDP to Active HDMI and 1 miniDP to VGA), whether this setup will work? or I must use only 2 miniDP to ActiveHDMI?
