Hi its my first post, but i have a problem yesterday suddently my pc detects 2 monitors (the second one virtual is unusable obviously) instead of one ,how do i uninstall the second virtual monitor?? And the performance dropped bout 50% in games
I'm pretty sure that merely means your video card supports 2 monitors but there isnt a second connected. As for the performance decrease, make sure you have all the right drivers and they are the most recent versions.
get a driver for your monitor if after youll install it there will still be two then manually remove the other from device manager and see if it comes back after a restart , windows obviously dont recognize your monitor as it identifies it as "plug and play monitor"
My point in the previous post, I have seen this very recently, and for some reason the Radeon secondary wreaked all sorts of havoc on the machine... Do yourself a favor and remove all video adapter drivers and start fresh....
