NEC P241W monitor, no force standby-mode >.<

Hi, I bought a 15" MacBook Pro Retina a few months back, to use in my home office, and on the road. I thought about buying a 27" Apple Thunderbolt display for the office, but I didn't need such a big screen, so I bought an NEC MultiSync P241W 24" display, instead.

It's a very nice screen. It has good connectivity (nearly equivalent to NEC's highest end display models), good color reproduction compared to Apple's screens, and a USB hub...and that's where I have a problem. Bear with me here while I explain...

As confirmed by my best research efforts, and a discussion with NEC technical support, for the P241W to enter standby-mode, the selected video signal must be interrupted somehow (as best as I can figure, that means I have to sleep or turn off the Mac). There is no force-standby feature on the screen itself, or in the on-screen menu, just the power-off button. Since I have an HDTV hooked up to the Mac as well, for watching video, I often don't NEED to keep the P241W powered up. In fact, in a dark room, I'd prefer to turn it off (or in this case, set it to standby). And there's the catch. If I turn the screen off, instead of setting it to standby somehow, I lose power to the USB hub, and amongst other things, the keyboard and mouse that are usually plugged into it. And of course I can't sleep/turn off the computer because I'm using it!

And so, none of this is a deal-breaker. I can always route my critical USB devices through a different hub, while the P241W is off, but it's still kind of frustrating.

Can anyone think of any way (maybe by use of a script, or some system preference that I'm unaware of) by which OS X might be able to cut the signal to a specific monitor, in this case to trigger standby-mode on my P241W?

Here's hoping!

I am not aware of anything in terms of software that can do this.

Let us know if you figure out a way to do it.
