Setup VNC Server on Windows - norihiro/obs-vnc GitHub Wiki

If you are to view Windows desktop by this plugin, these two VNC server applications are my recommendation.

For UltraVNC users who want to send secondary display, please check 'Show Secondary Display' in Screen Capture tab, UltraVNC Server Settings. The UltraVNC Server Settings in found in your Start menu, not the right-click menu from the task icon.
