A GTX1050 is unfortunately not compatible with the Vive Pro (min req. GTX 1070) or even the standard Vive (min req. GTX1060). A GTX1050 is a very entry level card that's not suitable for VR and you'll need one of the two corresponding cards to meet each system's respective minimum requirements. The Vive Pro is very demanding and realistically, you'll want a 1080 or better to have smooth sailing across the majority of apps.
