  1. Second monitor goes to sleep mode for no reason


    Hello, I have to monitors linked to my GTX 660. Main one through HDMI and the second one to DVI port via VGA adapter monitor has VGA.


    It's been working fine but whenever I wake my PC up from sleep mode the second monitor VGA one is in sleep mode and after logging in I have to press win+P clicking "Extend" option.


    This monitor also goes into sleep mode after I finish a League of Legends match after a match game turns off and you see match's summary in game's client.. When the game turns off this monitor goes into sleep mode. Suprisingly it sometimes DOES NOT happen which confuses me even more.


    My graphics card drivers and Win 10 are up to date.


    Anyone can suggest me a solution to this problem?

    :)

    monitor goes into sleep mode

    If I'm starting up my PC from sleep mode, my monitor goes into sleep mode 5 - 10 seconds after it gets going. If I'm turning on my PC, this isn't an issue; it works fine. My graphics card is up to date. Help!

    Using 2nd Monitor with Laptop and Goes Into Sleep Mode

    Hi Charlie,

    If your second monitor goes in to Sleep mode after connecting it to your laptop, it could be that some settings of the Power Options in Windows 10 are incorrectly configured. We recommend that you restore all power settings to default and see if the second
    monitor still goes to Sleep after connecting it. Here's how to restore the power settings to default:

    • Press the Windows logo key + I to open the
      Settings
      app.
    • From Settings, select System > Power & sleep, then select
      Additional power settings.
    • From the Power Options dialog box, select Choose when to turn off the display, then select
      Restore default settings for this plan.

    After setting it to default, observe if the issue persists. If it does, kindly connect the second monitor to another computer and see the problem is observed. Also, kindly use a different HDMI cable to rule out the possibility of a faulty cable.

    We look forward to an update from you.

    monitor goes into sleep mode

    Thank you Vijay for the quick response. The troubleshooter didn't find anything. For step 2, I was already using the recommended setting. I noticed that the fast startup only affects the startup when you're machine has been turned off, and currently
    that is when my monitor works, so I didn't want to change that setting. My monitor doesn't work if i'm beginning from the pc being in sleep mode.
