detects a non-real monitor...
Monitor doesn't exist and ..monitor not connected

still don't understand what you mean.
what do you mean by "detects"?

you get a popup in Windows stating that a specific make & model monitor is detected?
or it is showing up in the Radeon control software?

some game open on non-real monitor

and how does a game open on a monitor that you're not using?
how would you know that is was open if you're not viewing that specific display?
