Change power saving time setting.

Question

I have a Dell U2711 connected by DVI to my Windows 8.1 PC with an NVIDIA GTX 760 card. If I leave the mouse and keyboard unused for about 5 minutes, the screen goes black. If I then wiggle the mouse the screen display reappears. My windows settings are for the display to never sleep, so I think it's something set in the monitor. Is this true? If so, how do I change the time limit and/or turn it off completely? Thanks, Jim

I have found the solution.  I had the Windows screensaver set to blank the screen after 5 minutes. All OK Now.  Thanks.

There is nothing in the monitor OSD (On Screen Display) Menu to control power management. This is all done from the operating system. Test this:
* Disconnect the monitor USB upstream cable from the computer
* Disconnect all USB devices from the monitor USB ports
* The USB mouse and keyboard should be plugged directly into the computer

Yes...I couldn't find anything in the OSD Menu either. I'm not sure about your suggested test though. I have no USB cables or devices plugged into my monitor, just DVI and power.

I think there is a power setting in the operating system doing this. Is this a desktop or laptop?

It's a desktop. I have the following set... Control Panel\All Control Panel Items\Power Options\Edit Plan Settings > Turn off hte display: 30 minutes. (I would attach a screenshot but the 'Save' button doesn't seem to upload the file.)

Thanks for your suggestions. I did all of those except the PCI Express one which I don't seem to have. Sadly, the problem persists.

Test the monitor on another computer using DVI. If the issue does not appear, the fault is not with the monitor.
