Hi, I updated to the last version of AMD Adrenalin Software 18.9.3 because I play AC: Odyssey and I've got Slightly more performance in it. When I turn off one monitor, my mouse start to stuck and my screen freeze for a moment (every 2 seconds). And, evidently, when I turn on the second monitor, all is solve it.
At this moment, I have setting my second monitor to the lowest brightness it is possible (to waste the less energy possible ).
Thanks for watch and answer!
