    Why my monitor goes OFF after some standby time ??


    Hi,

    I have Windows 10 Pro, ver. 1709, on a Dell Vostro 3668 desktop.

    My monitor doesn't remain in stand-by mode (LED blinking) as much as required, but goes OFF both when the PC is idle & ON and when the PC is sleeping. In Windows 7 and Windows XP, the same monitor used to remain in stand-by mode forever (as much as I wanted) without going OFF. Now I have set the time for Display Turn Off on 15 minutes. This option is supposed to send it to stand-by mode and keep it there as long as I wish. But instead of that, after 15 minutes of stand-by mode it goes OFF.

    How I can make the monitor remaining in stand-by mode as much as I want both when the PC is ON & idle and when the PC is sleeping ??

    Hi newu873. Welcome to the TenForums @newu873

    When did this problems start?

    Can you recall any changes made just before?

    Have you reviewed your Windows Update history, particularly the driver section. Was anything installed on your behalf just before problem started?

    What type of monitor (Make Model) is this?

    If you switch the cables, at the monitor end, between devices does problem move to other screen?

    What card are you using (make / model) ?

    Have you tried uninstalling graphic driver and software with a tool like DDU and then re-installing?

    Hi Ken,

    Thanks for your help.

    "When did this problems start? "
    Since I first turned on my new PC with the pre-installed Windows 10 Pro. Before that, the same monitor went into standby mode smoothly and remained there as long as I wanted (LED blinking) in Windows 7 and Windows XP at older PCs.

    "Can you recall any changes made just before? "
    No changes were made before discovering this problem as it's a fresh new PC with pre-installed Windows 10 Pro.

    "Was anything installed on your behalf just before problem started?"
    No. The problem began from the first operation of the new PC. Later the system updated my Network adapter.

    "What type of monitor (Make Model) is this?"
    BenQ, purchased 8 years ago, with LED technology (not Plasma, etc) which was new for monitors that time. In the device manager now it's specified as Generic PnP Monitor.

    "......does problem move to other screen?"
    I don't have other screen.

    "What card are you using (make / model) ?"
    My Display adapter: Intel HD Graphics 630. The system says no updates are required for it. Perhaps one possible answer to my problem might be that my monitor is connected to the PC with simple VGA cable while the PC has also a HD socket. But the monitor hasn't got any HD connection. It has one another plug with pins which is twice bigger than the simple VGA. But my new PC hasn't any outlet for such type of connection but my previous PC had and I used to connect the monitor to that bigger (not VGA) outlet in my previous PC.

    "Have you tried uninstalling graphic driver and software with a tool like DDU and then re-installing?"
    No, I haven't. But why to use such a tool when the Device Manager alone can uninstall the driver ??

    Another guess is that this may require registry tweaking. At some other forum I saw someone having a little different problem with monitor. So he was advised to make some registry tweaking. I went to that advised place in registry and saw there a lot of options (entries) to tweak the different kinds of parameters of a monitor, related to Energy savings, etc. So I might need someone who knows perfectly this side of registry for energy savings at monitors. My guess is that there is a specific registry tweaking related directly to this specific problem with my monitor.

    Please take a picture of the other port on your Monitor, it is Benq but you didn't list model number.

    Your PC has HDMI and your monitor likely DVI.

    You can get and HDMI to DVI cable and your resolution will improve a great deal.

    List HDMI

    It's BenQ V2220 (so hard to find. Finally found it using the wonderful MonitorInfoView little application by NirSoft).
    Yes, it's DVI on monitor
    The image will improve with DVI-HDMI, but will it also resolve the stand-by issue of the monitor ??

    I can't be certain that it will fix it but a $30 cable with better resolution I would experiment.

    This would be the DVI end.

    Also please ensure in your monitor menu you have Auto Power set to OFF

    Hi Ken,

    Your reply solved my monitor issue of not remaining in stand-by mode as long as wanted.
    I set OFF in the monitor menu the Auto Power and it worked. But I never touched this menu after
    using it only once after buying this monitor. So actually I don't get how & why this parameter had
    any effect on the stand-by mode now and not before this during 8 years.

    Anyway, thanks for your help.

    Excellent.

    You may have been handling the monitor and engaged the menu. I've done that before cleaning my desk. Now I always shut them off. Thought I had damaged cable.

    Anyway it is fixed. Glad the forum could help.


    Happy New Year.
