We've had a couple of power outages recently and my monitor has been acting up. I've noticed a couple of things

1) Changing windows from app to app triggers the monitor display functions to pop up in the lower right hand corner for a few seconds. Not every app and not all the time, but very annoying.

2) For the second time today, my monitor has just shut off. Unplugging and replugging in the power cord to the power strip (Opti-USA surge/battery) allows the monitor to come back on.

I had a previous Samsung that I replaced caps on, and can't recall exactly...
