Welcome to Microsoft Q&A Forum!
Based on your description, you’ve noticed that the “Disconnect this display” option is missing from your Windows display settings. This is causing problems with Remote Desktop Protocol (RDP) sessions, as your remote desktop spans multiple monitors and you’re unable to restrict it to a single screen.
The reason why you encountered this issue:
- In Remote Desktop, display behavior is controlled by RDP session configuration, not by the local Windows “Disconnect this display” option.
When multi‑monitor support is enabled, the session will span across all available monitors by default. If specific monitors are not explicitly configured, the session uses all displays automatically, which can make it appear “locked” across screens.

- The “Disconnect this display” option is not always available for all monitor types or graphics drivers. It is typically present for external monitors (like those connected via HDMI/DisplayPort/USB-C) but may be missing for built-in or primary displays.
- In some Windows builds or with certain GPU drivers, Microsoft may hide or remove this option for stability or compatibility reasons.
- RDP sessions, by default, can span all available monitors if multi-monitor support is enabled, and without the ability to disconnect a display, you cannot easily restrict the session to a single monitor.
I would like to share the following recommended solutions that may help you.
1. Restrict RDP to a Single Monitor
- When launching RDP (mstsc.exe), before connecting, click “Show Options” > “Display” tab.
- Uncheck “Use all my monitors for the remote session.”
- This will force the RDP session to use only your main display.
2. Change Primary Display
In Windows display settings, set the desired monitor as your “Main display.” RDP will use this as the default if multi-monitor is disabled.
3. Physically Disconnect or Disable Monitors
- If possible, physically disconnect the unwanted monitor(s) before starting your RDP session.
- Alternatively, some graphics drivers (NVIDIA/AMD/Intel) offer their own control panels where you can disable displays.
4. Update Graphics Drivers and Windows
Ensure your graphics drivers and Windows OS are fully updated, as newer versions may restore or improve display management options.
5. Group Policy or Registry (Advanced)
- There is no direct Group Policy or registry setting to restore the “Disconnect this display” option, but you can control RDP monitor usage via GPO path:
Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Remote Session Environment > “Limit number of monitors”
- Set this to “1” to restrict RDP sessions to a single monitor
I hope this information is helpful and thank you for choosing Microsoft Q&A to raise your concern.
