    • You can use the GPO files included with Horizon, but they are going to apply these registry key settings. These keys should be modified on your virtual desktop and then restart the machine after making any registry changes to ensure they take effect.

      • I’m seem to be having the same issue. If I make a change in the GPO applied to my VMs, I don’t see the reg keys get populated down even after a “gpupdate /force” or a reboot. If I add the keys manually, I see no change in experience. Very frustrating.

        • What changes are you attempting? If you have the Horizon Performance Tracker installed (part of agent install) you can get some great insight into your active session including display protocol, transports, codecs etc..

          • Was just trying to adjust FPS and MaxBandwidth. Those settings appear to be taking now. Looking at performance tracker, I’m seeing a huge dip in FPS when trying to watch a video on one of our VMs.

  • I’ve created the BlankScreenEnabled and set it to 0 in the hopes that the active session shows the users screen on the Physical PC in order to project it onto a screen in the physical location. Any ideas why it isint working? We are running 8.0.0 build – 16592062
