I have a new Win10 computer using a FirePro w4100 card.
I was sure to get the correct MDP-VGA active adapters.
I have 3 monitors.
Yesterday, everything worked fine.
Today, only the 2 "same" monitors work. The 3rd monitor says "out of range".
Sometimes, one of the "same" monitors will combine with the 3rd monitor.
If I identify, it will show as 1|2 and the two monitors will have the same screen output.
This is erratic behavior.
I was originally using the driver Win10 installed, but after having some problems I used the driver from my install disc, but it didn't make any difference.
