The procedure prior to Windows 10 was the following:
- Right-click on the desktop and select "Screen Resolution" or "Display Settings"
- Click the "Detect" next to the main monitor
- Choose "Another display not detected" -> Multiple displays -> Try to connect anyway on VGA
- This will add a second virtual monitor which you can then configure as a real monitor
Other solutions which would also work for Windows 10 would be to purchase a hardware dongle to connect to the HDMI, DVI or VGA connector of your system to simulate that a monitor is actually connected. There are even hand-made solutions that consist of soldering resistors on the pins of the VGA port and risk damaging your computer.
Windows 10 removed the option of activating a VGA monitor even if it wasn't connected. We are providing here a simple and free solution to create a "software" monitor on your system to use it as you used to prior to Windows 10, e.g. to create a second virtual monitor for USB Mobile Monitor.
Here is the procedure to add a virtual monitor to your system (Windows 10 Only!)
- Download our virtual display driver from https://www.amyuni.com/downloads/usbmmidd.zip
- Unpack the zip file to an empty folder, e.g. c:\temp\usbmmidd
- Make sure you read the License.txt file as with any other software product
- Open a command prompt window as Administrator (you cannot add a device to your system unless you "Run As Administrator")
- Run the following commands:
- cd c:\temp\usbmmid (or whatever destination folder you chose)
- deviceinstaller64 install usbmmidd.inf usbmmidd
- Make sure you see the message that the drivers are signed by Amyuni Technologies Inc. This is a confirmation that the drivers went through Microsoft driver signing procedure and are virus free
- deviceinstaller64 enableidd 1
The included batch file usbmmidd.bat runs these commands automatically and selects between the 32- or 64-bit version of deviceinstaller.
If you are not comfortable opening a command prompt and entering these commands, right-click on usbmmidd.bat and "Run As Administrator."
That's it. You now have a high definition monitor in your Display Settings. The format is fixed for 1920x1080 pixels but you can position the monitor, extend the desktop or do whatever you do with a real monitor.
To deactivate the virtual monitor, run the command:
deviceinstaller64 enableidd 0
to reactivate it:
deviceinstaller64 enableidd 1
To completely remove the drivers from your system, you can either go through the Device Manager and uninstall "USB Mobile Monitor Virtual Display", or run the commands:
deviceinstaller64 stop usbmmidd
deviceinstaller64 remove usbmmid
