Currently in my settings I have my monitor set to switch off after 15 minutes of inactivity. After 15 minutes it appears to work, monitor goes blank for about a few seconds but then it comes back on and this repeats. Ive tried unplugging my mouse & keyboard thinking maybe they are waking it back up but that had no effect. I've done an online search and most of what turned up was resuming issues i.e. monitor stays off. I've also tried changing the times but no luck still the same. I've also tried the force off command and it does go blank for a few seconds but again monitor will come back on. This has been going on for months now. I was hoping an update would have fixed it but no luck there either. Any help is appreciated. Thanks.
