I am getting that error when i play Minecraft.
I updated my graphic driver but i still get the error.
Someone know how to fix this?
The Error means what it says - your GPU is confused about which display exactly requires optimization.
Go to the NVidia Control Panel, set Multi Display/Mixed GPU Acceleration to a Single Display, then set the Mode to Maximum Performance. It should help. You can also set Threaded Optimization to Off or Automatic (in 3D Management, Global Settings tab).
In the very first menu you see when opening NVidia's utility - with the rotating logo. Alternatively you can enter Advanced Settings by clicking the 3D settings link in the left-hand menu.
