I have 10 peices of 55 inch display. 9 displays must be eyedentified as one display and rest of single display operate as single mode.
Yesterday , all eyedentification settings were lost. All displays are operating as single mode.
I tried to reconfigure, but it didn't work. And I installed OS again, after OS installation all three AMD firepro GPU's driver's installed automatically. But it still couldn't load 3 displays. Rest of 7 displays indentified by windows.
