Just so you know, for anyone that uses a backup generator - even the line conditioning consumer grade UPS units will not accept the dirty wall power from the generator so the UPS will run out of power and shut down in 20 - 30 min (or whatever it ends up being depending on your ups model and your system load). I added a dedicated tripp-lite line conditioner before my existing ups rather than buying a very expensive ups model from manufacturer's commercial product lines. That way the UPS always receives clean power and won't run off the battery. I still need the UPS for the transition periods to and from my whole house generator though, and as a safety feature for soft shutdowns if ever necessary. The alarm is a nice feature too. I think this monitor is sensitive to electric fluctuations though. I could have swore that when I hit my metal usb hub housing with static electricity from my finger once that the OSD popped on. I've only seen the OSD pop on a few times other than that, very rarely. I'm not certain if they were electricity related now or even a desk bump. It was almost like a monitor wake up event I guess and happened too infrequently to investigate. So, I'm not sure even a ups and line conditioner will fix the rare OSD momentary pop up or the monitor wake up and stay on issue.
