    Dual Monitor keeping secondary monitor(turned off) active/alive


    Hello,

    i have following problem i would like to fix.

    First my scenario.

    I use Windows 10 OS with 2 monitors.
    My primary monitor is turned on and my second monitor is turned off.
    I programmed a application that starts other applications and moves them to the second monitor (which is turned off all the time). The reason for that is that my application reads color values of the other applications which need to be visible for that. But i don't want them on my primary monitor where i work. That is the scenario and it works flawless.

    Now to my problem
    Sometimes i want to turn off my primary monitor too (going afk for few hours and want to save power), but the color reading should still go on at the secondary monitor. When i come back and turn the primary monitor back on the applications that should be located on the second monitor are fully maximized on my primary monitor.

    I guess it has something to do with power management, but i could not fix the problem.
    Would love to hear some wisdom from the experts here.
    Thanks in advance.

    :)

    Hi David,

    About your concern to set which monitor is primary or secondary, follow the steps provided below:

    • Go to Settings > Click System > On the right panel, select
      Display.
    • Under Customize your display, drag the box that has number
      1
      on it depending on how you want to position it.
    • Click Apply > Hit Detect to make sure which Monitor is the primary.
    • Close Settings.

  3. Single monitor=no transparency in Start menu on dual monitor system

    Hello, I can't find any information about this one so here it goes.

    My Windows 10 is a dual monitor system and I don't get this problem when both monitors are enabled but when I game I disable the secondary display and then on the primary display the Start menu will lose transparency. It makes me sad. Dual Monitor keeping secondary monitor(turned off) active/alive :(

    I have installed color profiles for both displays and set them as primary profile for each one. I have also calibrated the color of both displays.

    Primary display is AOC 2460 connected with DVI-D

    Secondary display is Acer G246HL Connected with HDMI

    Graphics card is Nvidia Gerforce 1050 TI 4GB and it has latest drivers

    Operating system is Windows 10 Pro v. 1803 (OS-build 17.134.228)

    Steps to reproduce:

    • On dual monitor system disable secondary monitor
    • Open Start menu and transparency will be lost
    Additional information:

    CPU overclocked with multiplier but was at Stock settings when OS was installed

    GPU overclocked with Asus GPU Tweak II

    Setting Up A Older Secondary Monitor


    ok decided to reopen in the hopes someone might have a solution for a new issues i noticed. when i do a restart the secondary monitor takes over, and not until windows is about to go to the desktop does the secondary monitor turn off and the primary display turn on. i would think there is some way to make the default monitor stay on during a reboot. any suggestion would be great. thanks
