I keep reading conflicting articles about this. does this option even exist on the latest windows 10. if it doesn't, it sucks. I'd really like to conserve power if not in use. I noticed it dimmed seconds before turning off the display. I don't want it to turn off the display in such a short time frame, and I don't want it to go to sleep. I want it to dim after 5 minutes and turn off the display after 10. is that doable?
