nec monitors won't wake up

I have two NEC PA272W Spectraview monitors connected to a 2013 6 core, MacPro with dual 500 video cards and 64 gigs of memory. I have tried all the monitor settings to put them to sleep and wake them up. They will go to sleep in several of the auto off settings but won't wake up. If I leave them on all the time the computer will blank the screen, but it still glows indicating it is drawing a lot of power.

Is there anything I can do to get them to sleep/wake like all the other monitors I have had?

thanks,

Mike

MacPro, Mac OS X (10.5.6)

Yup. Go into system preferences (under the Big Apple in the corner of your screen)then go to Energy Saver. there should be a slider there for Display sleep. You may also have play with the screen saver settings

sorry, I'm not super familiar with NEC monitors, but hopefully what I've written will make some kind of sense to you

really-you're still running Leopard? Hmmm.......

I got a reply from NEC Display support. This is a known problem with their monitors and Mavericks. They made the following suggestion which seems to be working:

"Dear Michael,

The Off mode should be set to Standard. I have spoken with a level 2

technician, who gave me some trouble shooting that you may want to try.

1. Disconnect the signal to the monitor, either by turning off the computer or

disconnecting your connection cable.

2. The "NO SIGNAL" message will appear on the screen. Press the RESET and EXIT

buttons simultaneously 9 times when you see this message.

3. You will then have the option to change the DP PLL PMS POWER setting to ON.

4. Also, please ensure that the power save timer in the advanced menu is shut

off.

Please let us know if this works for you.

Thank you,

Cody

This worked for me running OS X El Capitan.

Prior to making the setting there appeared to be some form of signal timeout on the NEC monitor, such that when powering up my MacBook Pro if the monitor did not receive a signal from the graphics card in the MacBook Pro then it gave up and displayed "no signal". The only way to make the NEC monitor work was to power cycle it. But now works fine post this setting change on the NEC monitor.
