I just bought a brand new NEC EA261WM-BK 26" monitor two days ago for work purposes and I noticed a very strange thing happening with it. The screen will not stay in stand-by mode for longer than a few minutes no matter what and keeps turning on all the time and then stays on permanently. I tried using my Google-fu but it is failing me on this one. I found thousands of questions with people complaining that their screen will not enter stand-by or will not wake from stand-by, but not a single question or problem describing anything like what I am experiencing.
Again, the problem is that the screen, even if completely disconnected from the computer except for the power cable which is plugged into the wall will only stay in stand-by mode for a few minutes and will then wake up and stay on permanently. This is (a) a huge energy waster, (b) shortens the life span of the screen as the screen is on 24/7, (c) extremely annoying for two reasons (1) I paid ~$750 for this screen and (2) I am not about to hit the power button on the monitor every time to make sure it stays off as I should not have to do this on a ~$750 screen.
To top it off neither NEC nor the distributor where I bought the screen provide 7-day per week support so I cannot even get in touch with anyone, and I most certainly do not want to RMA a brand new screen to the manufacturer to get some refurbished POS back.
What gives?
Edit: Please do not get into a discussion "why NEC" or "you should have bought Samsung" or whatever. I am looking for genuine help here if anybody has any ideas. I have never experienced anything like this before, ever, nor heard of it.
