BTW, I don't know if it's the same for 931BW, but my dad owns 926BW and it is fvsking annoying. First, when monitor goes into standby when you turn off your computer, the power led starts blinking every second. This in itself is super annoying. Why Samsung couldn't just install dual color led and turn it red or yellow to indicate monitor is in standby, why do they insist on bling blinking? Second, I think half of the power consumed by the monitor must be going to light the power led. It is so bright that in the night it illuminates half the room (I'm not kidding here, think sunbeam rheobus blue leds kind of brightness). It's not so bad during the day, but if you intend to put it in the same room you're sleeping, be prepared to manually push power button on your monitor every night.

the humming sound from the backlight or built-in power supply has became a struggling for me, it's very obvious in a very quiet room. it's noisier than my computer for sure.

anyone who bother to read this forum would find it annoying. all your effort on silence your computer could be destroyed by the monitor.

i'm not sure if this is an individual case but the review did mentioned the humming sound. if you buying any LCD monitor, it's better to check them in the shop, both the display quality, and any noise coming out of it...
