I have a desktop PC running Win 10. I now always get a device connect/disconnect sound moving the mouse to wake the monitor. Except for when I actually plug in or remove a device, the sound only happens when I move the mouse to wake the monitor. After the screen turns on there is a rectangular box that appears for a few seconds to the bottom right of the screen. It says from top to bottom: "Eye Saver Mode" "Volume" "Features" "Eye Saver Mode Off". The monitor is set to sleep after 15 minutes. Not hibernate. I never had this issue. It did not start until after I moved my system and set it back up. Any suggestions on which steps and resolve this would be most appreciated.
