Windows 7 keeps sending monitor to sleep

The only time I have ever seen "No Signal Being Received" is when the PC is turned off and the monitor is on. Is your PC still turned on when you see the "No Signal" on the monitor?

You should always see no signal received when Windows turns off the monitor because that is exactly what it does. It stops sending a signal to the monitor.

Confirmed just now, MacGyvr. You are correct. Perhaps bigmck has just never noticed it? A very easy oversight if one is not sitting at their computer when the monitor goes off - especially depending on the power settings for the monitor. For example, if one has the monitor shut-off set for a long duration one might never see it actually shut off and the resultant "No Signal" message. Often the message is so short, on some monitors, that it can be easily missed even then.

Set your screen saver to blank. Turn off display 10 minutes.

I thought this had solved it was really happy. Then the screen faded to black again. There are no sleep options on either the monitor or TV, so I really don't know what to do. I read somewhere that this could be a registry problem? If that makes any sense.

Hi,

I'm not sure from your previous attempts whether you have tried this, but can you please go back to your Power Options, and check the individual settings for "High Performance" - see image.

Also : you mention a controller : can you tell us a bit more about this controller? make, type etc.

Hi, went into every power option, balanced, high power etc. Everything is set to never. Changed advanced power settings to never on everything possible but am still getting the same results.
Also the controller is a PS3 controller connected via USB.

Just a follow up for anyone else who may be having this problem and searches for solutions. It was an Asus driver called EPU-4 Engine that was overriding the W7 power settings and causing the monitor to turn off after 20 minutes.

Had the same problem and thought I turned off everything..


go back into control panel and click
hardware and sound/power options/change plan setting/change advanced power setting

and look for PCIexpress/link state power management and turn it to off
