    i am running a mac pro mid 2010 with a AMD Radeon HD 7950 and 4 monitors - 3 on hdmi and one on DVI to VGA converter.  I upgraded to High Sierra OS and now the DVI signal is erratic and unusable,  It flickers and ghosts and mirrors the main screen

      i am running a mac pro mid 2010 with a AMD Radeon HD 7950 and 4 monitors - 3 on hdmi and one on DVI to VGA converter.  I upgraded to High Sierra OS and now the DVI to VGA signal is erratic and unusable,  It flickers and ghosts and mirrors the main screen.  there are no drivers listed for this most recent mac OS.  Any suggested fixes?
