    Choose GPU card for acceleration


      Hello everyone,


      I use Lightroom 6 on my workstation (laptop MSI GT70) and I have two graphic cards:

      -Intel(R) HD Graphics 4600

      -NVIDIA Quadro K3100M


      Lightroom try to use the HD 4600 card when I check "use GPU acceleration" and it does'nt work (blue rectangle in development mode).


      If I use an external screen I can disable the HD4600 card and so lightroom use the Quadro and it's working.

      The issue is that most of the time I don't have a second screen and I can't disable the HD4600 (nothing on the screen if I do that...)


      Is it possible to force lightroom to use the secondary graphic card?
