    My monitor sometimes after long time goes itself to sleep mode.


    Hello all. I have a little problem i think with my monitor. Sometimes, if I turn the monitor off, and leave the computer on overnight, when I turn monitor on in the next morning it won't display anything because monitor automatically goes on sleep mode.
    When i switch off the monitor and try to switch it on (machine is running overnight)in the next day, the monitor shows nothing. There is no display.
    I have to press a key or move my mouse for my screen to come back.
    I have every sleep and auto-powerdown function turned off on my PC, I use no power saving mode whatsoever.
    Sleep mode, hibernate,turn off display are set to never.Also i am not using any screensavers.
    Also i checked monitor options and AUTO POWER OFF is OFF.
    Any suggestions why its going itself to sleep mode?

    The only thing that comes to mind would be to check in Device Manager, right click on the Monitor, click Properties. See if it has Allow Device to be Turned Off to save Power checked/enabled.

    I understand. I read your first post. But I thought it would not hurt to look at the driver setting. I have seen systems wake up for no reason just because the network card driver was set to allow "wake on Lan" even though there was no discernible event happening.
