If you’ve been working with GPU deployment in your virtual desktop environment (XenDesktop or XenApp), you probably also installed HDX 3D Pro. Leveraging the GPU, you can use more graphic-intensive applications. Some of these graphic-intensive applications sometimes launch in fullscreen mode by default (think of benchmarking tools or videogames). The result of starting an application in fullscreen mode could be the following error:
--------------------------- Citrix HDX 3D Pro Warning! --------------------------- Full Screen Applications are not supported in Citrix HDX 3D Pro. Press Ok to exit. --------------------------- OK ---------------------------
