VNC Mirror Driver

VNC Mirror Driver by RealVNC Ltd. is an optional Windows display driver designed to accelerate screen capture for VNC Server. By mirroring the desktop at the driver level, it detects screen changes more efficiently than standard capture methods, helping reduce CPU usage and improve remote desktop responsiveness—especially on older Windows systems and over low-bandwidth connections. It is most useful in legacy environments where modern capture APIs are unavailable, and it can assist with capturing the logon or lock screen on certain older Windows versions.

Key benefits

• Faster screen update detection for smoother remote sessions
• Lower CPU overhead compared with polling-based capture
• Improved performance on busy desktops and slower networks
• Optional component that can be enabled or disabled as needed

Compatibility and notes

• Intended for legacy Windows platforms that support XPDM mirror drivers (for example, Windows 2000/XP/Server 2003 and some Vista/Windows 7 systems)
• Not supported on Windows 8/Server 2012 or later; newer Windows versions use modern capture APIs instead
• May disable Aero/DWM visual effects while active and can impose color-depth or composition limitations
• Requires administrative privileges to install; uninstall or disable if you encounter display artifacts or conflicts with GPU-accelerated applications

Use VNC Mirror Driver when running VNC Server on older Windows systems and you need the best possible capture performance or the ability to view certain secure desktops. For modern Windows releases, RealVNC recommends using the built-in capture engine rather than a mirror driver.
