In my previous post about full screen applications in HDX 3D Pro, I explained possible solutions to the “Full Screen Applications are not supported in Citrix HDX 3D Pro” message. In short, the issue is due to the fact that the application does not use the same resolution as your HDX session.
In the mean time, Citrix release XenDesktop 7.6. The XenDesktop HDX 3D Pro VDA now contains an experimental fix to support full screen applications in any resolution. This fix is explained by Rachel Berry (Product Manager HDX Graphics for XenDesktop/XenApp, twitter @rhbBSE) on the Citrix Blog: http://blogs.citrix.com/2014/10/24/hdx-3d-pro-experimental-support-for-full-screen-apps/
Enable support for full screen applications
As described in Rachel’s blog post, you have to modify the registry on the machine where your VDA is installed. Insert the following value:
[HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\HDX3D\BitmapRemotingConfig] “HKLM_EnableFSA”=dword:00000001
To check this feature out, I’ve upgraded my lab environment to 7.6 (both DDC and VDA) and injected the registry value.
Note that this configuration is experimental and currently not officially supported by Citrix.
