I'm trying to create a "virtual monitor" in Windows (XP & newer). For example, let's say my desktop looks like this:

enter image description here

I want to add a monitor virtually so it looks like this without any change in hardware: enter image description here

How do I do this? Do I add a virtual driver? Or trick Windows into thinking there is new hardware?

    considering there might be a programming outcome, I think it fits on StackOverflow. It's also a duplicate of http://stackoverflow.com/questions/11922174/creating-a-virtual-monitor-the-display-device?rq=1 but neither have valid answers. – Jason May 15 '13 at 00:09

  • Voted to reopen - I need this kind of program for programming – Gabriel Jul 22 '13 at 15:01
  • There is hope, here: http://virtualmonitor.github.io/ Looks like a work-in-progress and only supports windows 2000 - windows 7, but he's looking for help with windows 7 - 8. – Bill Burdick Mar 14 '14 at 08:42

Well, once upon I was in same problem and someone reccomended to me to override EDID data.

The EDID (Extended display identification data) data structure have all the info of your graphic card and other video sources.

You can see a tutorial for how modify EDID here.

The tutorial only applies to Win 7, Win server 2008 and Win Vista...

I don't try the following because I'm a bit afraid of manipulating these data, but... if you're average in these stuff you could try ;)

If you prefer a hardware solution, perhaps DVI Detective may help you. In his website they claim that DVI "provides a virtual EDID". Also, this hardware protects the EDID data, so, there's lower risk to do very much damage...

Hope this helps :)
