Very happy with purchase. I like the power save mode, reduced blue light option and office modes which help reduce eye fatigue. The bigger screen I was looking at didn't have these options so I got this one and am so glad I did. This was a good price. The power save activates if you move away from the screen. I need to experiment with the settings as it keeps activating if I lean back. I had to look for online instructions as the included paperwork wasn't much use at all.
