I continue to have issues with Quadro 4000 Video cards displaying the desktop when opening Solidworks 2014 SP5.  Even after doing a clean install of the updated drivers 331.82 It still does not correct the problem.  Went as far as just installing video drivers.  I have older FX3800 and FX1500 and have had no problems with them.  Does anyone have any new ideas??  I'm considering changing out the cards.
