Dell Wyse ThinOS Version 8.6.1 Administrator's Guide

NOTE: :

• Dependence 1—RDP GFX status, H.264, and VOR work only when GFX is enabled.
• Dependence 2—VOR is dynamic. So the enablement/disablement of VOR dynamically changes during the change in the video resolution (enlarge/shrink).
• Dependence 3—H.264 enablement is decided at the beginning of connection, depending on the maximum resolution available for the session.

If H.264-AVC444 is enabled, VOR is not used in Microsoft broker 2016, and Windows 10/2016 sessions without the RemoteFX GPU. If you disable H.264-AVC444, VOR is used.

In RDP session (RDP 8.1 and later), VOR, H.264, and H.264-AVC444 are enabled by default. To disable these parameters, use the INI parameter— SessionConfig-RDP EnalbeGFX=yes EnableVOR=no EnableRDPh264=no.

When you connect to an RDP session in Windows 8.1 or Windows 10 with RemoteFX GPU adapter, H.264-AVC444 is used irrespective of the H.264-AVC444 group policy configurations. If you disable the H.264 feature by using the INI parameter, the VOR codec is used in RDP sessions. However, graphic-related issues are observed in RDP sessions. The VOR codec is not used when you disable H.264 using the INI parameter.
