    Monitor turns off while in power saving / standby mode.


    I have a multi monitors setup and notice that one of the monitor keeps turning off after some time period while in standby/power saving mode.

    The only way to turn it back on is by physically pressing/touching the power button...

    I have tried DP, HDMi cable and the issue still occurs with both cables.

    Does anyone know what is the cause of the problem ?

    Since it's only one monitor has the Menu on it been checked for a setting that can cause it?

    yes,
    I have thoroughly checked the settings and there is no settings that would do this behavior.

    From my own experience, I have never seen any monitor that would have setting that does this.

    Since no make and model of monitor is known it was only a guess.

    I didn't find that model but for a similar model I read that it follows the energy star 8.0 specifications. I went to read them. It seems that for some devices there is a deactivation timer that puts them in OFF mode. I read elsewhere that if when the monitor goes into standby an animation is activated then there is another possibility for this sleep timer. You should check all power saving settings. Do you have a remote to turn it back on?

    I just realized I made a typo with the first model I wrote.

    In device manager it shows as "Phillips 328P6V"
    So most likely it is this model = Phillips Brilliance 328P6VJEB/75

    can you give me the link where you reading this info?

    So you saying that for "some devices there is a deactivation timer that puts them in OFF mode"
    Does that mean the device is a GPU that is putting this timer or the monitor is putting this timer when that type of gpu is connected?

    There is not really an animation but the monitor logo appears.

    I check power saving settings in windows but there is no setting I am aware that would do this..
    maybe you can look at your own to show me if there is any that would cause this.

    There is no remote,
    I need to touch the capacitive power button to turn in back on each time this happens.

    Unfortunately I don't have a fixed PC with a multi monitor configuration. But I'm reflecting the same on how to find a possible solution.

    Meanwhile, here are the links I am reading:
    https://www.energystar.gov/sites/def...Nov-2021_0.pdf

    And the monitor manual here on this page in particular:
    Power Management - Philips Brilliance 328P6VJEB User Manual [Page 22] | ManualsLib

    First of all I would check in the management of Windows devices if the graphic card to which the monitor is attached has an option for the management of the power supply. Generally the devices have an "allows Windows to turn off the device to save energy" or something similar. See if there is an energy saving tab in "device management"


    Then I would look, as written on the manual, if there is a VESA DPM management software and if the graphics card supports it.

    Then if these roads don't give a solution I would do something to keep the video active.

    I think the monitor itself has a timer that makes the monitor from Stanby to Off. If it were so, just make sure that it does not go to standby/Sleep.

    Then try a Windows screenverver. Or make Windows don't go to standby. I believe there are various interior ways. I don't know them all maybe someone here of the forum is more informed.

    Hi,
    I have the same monitor with the same problem.
    I actually have two of them , and the the other doesn't do this. So it's a problem with the monitor and nothing to do with any computer setting.

    There is nothing in the OSD menu that seems to affect this behaviour, unless there's an "admin" mode or something.

    I've never had this problem, and I don't have a solution, possibly new items to check.

    In this 6y old thread Why my monitor goes OFF after some standby time ?? with the same problem there was an "Auto Power off" monitor setting that was causing the same issue, and turning it off fixed the problem.

    The user said in older computers with win7 or XP there wasn't any problem with the same monitor. Turned on by accident? Maybe, but a hidden factor (I think) would be if there's monitor driver installed or not. This is frequently overlooked but the monitor and graphics card are able to set up the link correctly anyway, essentially correct refresh for every resolution. For other not so critical features, the monitor driver might do a difference. Maybe there're tabs with options in the Device Manager monitor's properties window.

    If there're different connections types possible (VGA, DVI, HDMI, DP) they could also make a difference.
