How to install Server VDI with HDX 3D Pro enabled and confirm it was installed correctly.
To install Server VDI with HDX 3D Pro enabled, use the following command line:
DesktopVDA.exe /quiet /servervdi /controllers /enable_hdx_3d_pro /optimize
NOTE: For more details about all the switches available to install VDA using the command line, refer to session "Command-line options for installing a VDA" available at http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-13/install-configure/install-command.html

Run the "HDX 3D Pro Health Check Tool" within the Desktop ICA session and go to Graphic - Thinwire.
