Youtube has a feature where when browsing videos, you can hover your mouse over a video and it will play the video with no audio. When doing so, my entire screen goes black briefly, then comes back, and when moving the mouse off of the video, it again goes black and then returns. When it returns, a notification from my monitor appears telling me I am now using display port 1. This notification happens both when moving the mouse on and off of the video. I have tried updating my monitors drivers, and it still happens. I have tried with google chrome, and firefox, and it does not happen with those browsers.
