Fullscreen applications with HDX 3D Pro – Part 3

A few days ago, I wrote a post about Citrix’s fix for fullscreen applications in HDX 3D Pro connections. In that post I mentioned the fact that by default, an application launched in a resolution larger than the session’s resolution, will be trimmed off. Rachel Berry (Product Manager HDX Graphics for XenDesktop/XenApp, twitter @rhbBSE) provided me with some feedback on my article. Especially this part:

I understand why the application behaves in this way. The best way to fix such an challenge is to “scale” the application (I don’t even know if this would be possible programmatically) so that it scales while it maintains the aspect ratio. This way you would always see the entire application, no matter what the resolution is.

One feature of Citrix Receiver, which I knew exists, but never used, is the ability to scale the session completely. I investigated this feature as solution for the trimming of high-resolution applications.

Fullscreen applications with HDX 3D Pro – Part 2

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.
