Let’s FIX Black or frozen screen in Skype for Business during Screen Share. In this post, you will get to know how to resolve the display screen frozen issue while sharing the screen during a Skype for the Business session.
The Video-based Screen Sharing (VbSS) capability added to Skype for Business 2016 to improve the screen-sharing experience. It provides an optimal meeting experience because it significantly improves the resolution and refreshes the rate over a standard meeting session.
Note – VbSS is only used when all participants in the meeting are using the latest version of Skype for Business 2016 client. FIX Black or frozen screen problem will be resolved by this change because the registry entry is going to change the protocol Teams/Skype for Business is using while performing the screen share operation.
When a user shares a desktop in a Skype meeting, the screen refresh rate drops or the desktop is blurry for other users. This issue occurs because of a problem in the video-based screen-sharing (VBSS) feature as screen sharing always uses Remote Desktop Protocol (RDP).
Workaround – FIX Black or Frozen Screen
Disable VBSS and enable Remote Desktop Protocol (RDP) based screen sharing to improve connection times, works better in low-bandwidth conditions.
To do this, make the following change in the registry if you use the 32-bit, 64-bit version of Skype for Business 2016 and restart Skype –
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Lync] "EnableConferenceScreenSharingOverVideo"=dword:00000000 "EnableP2PScreenSharingOverVideo"=dword:00000000 [HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Office\16.0\Lync] "EnableConferenceScreenSharingOverVideo"=dword:00000000 "EnableP2PScreenSharingOverVideo"=dword:00000000
You should now see the registry is successfully added.
NOTE! – We have seen a better user experience after the change in Teams calls with some skype users in the WVD world. The default protocol used when a user attempts to share their screen with Teams or Skype for Business is video-based screen sharing. However, after the above registry change, the RDP protocol shall be used for screen sharing in Skype and Teams.
