Based on Microsoft Indirect Display Driver Sample. This creates a virtual display in Windows that acts and functions just like a real one. It's useful for streaming, virtual reality applications, recording, headless servers, etc. The benefit over a physical display is the ability to adjust resolutions and refresh rates beyond the physical displays capabilities. For example, this would enable the ability to stream a game from your home PC using game streaming software at 240hz at 8K while owning a 60hz 1080p monitor (unrealistic, but explains the abilities well). For servers without displays, this enabled remote desktop and screen streaming to other systems as if there were a display installed.
Supports emulating resolutions from 640 x 480 to 7680 x 4320 (8K), and refresh rates including 60hz, 75hz, 90hz, 120hz, 144hz, 165hz, 240hz, 480hz, and 500hz.
This project uses the official Windows Indirect Display Driver combined with the IddCx class extension driver.
Important
Please make sure you download the correct version for your operating system!
- Universal Driver - 24.10.16 (Windows 10/11) - Added a lot, Check release page for notes
- Download the latest version from the above or the website, and extract the contents to a folder.
- Copy the
\IddSampleDriver\folder and its contents toC:\IddSampleDriver\before installing the driver (important!). - Right click and run the *.bat file as an Administrator to add the driver certificate as a trusted root certificate.

- Click "Have Disk..." and click the "Browse..." button. Navigate to the extracted files and select the inf file.
- You are done! Go to display settings to customize the resolution of the additional displays. These displays show up in Sunshine, your Oculus or VR settings, and should be able to be streamed from.
- You can enable/disable the display adapter to toggle the monitors.
Ps. Make sure that options.txt is accessible for the system at C:\IddSampleDriver\options.txt or the installation will fail.
- Download the beta version and extract the contents to a folder.
- Copy the
\VirtualDisplayDriver\folder and its contents toC:\VirtualDisplayDriver\before installing the driver (important!). - Right click and run the *.bat file as an Administrator to add the driver certificate as a trusted root certificate.
- Don't install the inf. Open device manager, click on any device, then click on the "Action" menu and click "Add Legacy Hardware".
- Select "Add hardware from a list (Advanced)" and then select Display adapters.

- You can enable/disable the display adapter to toggle the monitors.
- Open device manager
- Locate Display Adapters
- Right click on IddSampleDriver, choose "Uninstall device"
- There is a new popup window, in there click Attempt to remove driver for this device.
Next instructions are for those cases where the device is removed from the system, but driver stil remains. This happens when there is a connection to the device while trying to remove the drivers. To remedy this, there is a a few tricks built into windows. So here goes:
- Open up a powershell terminal and input this:
pnputil /enum-drivers- Locate iddsampledriver.inf, there might be multiple pages of text. Make a note of the "published name", it's often unique for your system, but might look like "oem139.inf"
pnputil /delete-driver oem139.inf- (If you still get multiple displays after uninstall, try to repeat uninstall procedure in safemode.)
