On every boot up I have to adjust the gain on the facial recognition to get it to recognize me. I have gone into the command center and saved with the gain at 100%, but to no success. When I slide the indicator to 100% and select apply and ok, I believe it should save, but that doesn't happen.

Oh no ... really? It's happening on this monitor too? I have the Dell 2740L as well which has this issue and I thought it wouldn't happen to this model. It's really bad on the 2740L, and Dobr and nokey (another post thread) captured the exact way it shows up in photos on the U2413.

When my laptop is turned on watching a video and I start charging it, it will most likely say "plugged in, not charging" and give me a message about getting a Dell 45W charger (I am using the official charger that came with the laptop).
