I have this problem (with HD 3000) - but if I move my cursor into the Quicksync designated monitor (e.g. to the bottom right corner) then the cloned cursor on my primary display disappears
Sometimes it does come back after awhile, but then I just repeat to make it go away again.
@GameShine's suggetion didn't work for me. If I try to select the first "Try to connect anyway on: VGA" option then I get an error message when I click Apply "Unable to save display settings". It only works if I select the 2nd VGA option.
I wonder if the problem is caused by Virtu MVP? I have Lucidlogix Virtu MVP 2.0 installed but it's disabled.
