Someone i know has a Dell precision m6500 with a Quadro FX 3800. Now before he updated to Win10 his Eiso screen would work fine via display port. After upgrading to Win10 the screen won't work anymore. Now, he did try drivers, he opened a case with Dell's support but nothing. Anyone has any ideas?
So, if the hardware works then it sounds like drivers... What drivers did he try? The 189.21's from 2010 that Dell offers, or the 342.00 from nvidia? This isn't an "Fn-F8" problem? - just need to enable external display?
