This problem also occured when i moved from 8 to 8.1, and was pretty much fixed after downloading the latest driver. However I'm at this moment in time I'm not sure that Intel have pushed out a driver which will fix this problem, unless anyone can show me otherwise. I did temporarily fix the problem by plugging two monitors in to the integrated graphics card (DVI, VGA) and just running the one off my dedicated graphics card (VGA) for now. </P> Wed, 05 Aug 2015 17:51:32 GMT https://community.intel.com/t5/Graphics/Multiple-monitors-broken-with-Windows-10-upgrade/m-p/290605#M11806 OBake 2015-08-05T17:51:32Z https://community.intel.com/t5/Graphics/Multiple-monitors-broken-with-Windows-10-upgrade/m-p/290606#M11807 <P>The laptop has switchable graphics, this feature requires an additional driver and it is provided with your laptop manufacturer.
