    How to Set a Display as Main Display in Windows 10

    information   Information
    If you have two or more displays connected to your PC, then you will be able to select which display you want as the main display for all users by default.

    The display set to be the main display will act as the active desktop, show the clock and notification area on the taskbar, sign in, lock, and CTRL+ALT+DELETE screens will open on, and most items will open on the main display by default when you initially open them.

    This tutorial will show you how to set a display to be the main display when you have multiple displays connected to your Windows 10 PC.

    Note   Note
    Any user on the PC will be able to set a display as the main display.

    The display set as the main display will be applied to all users on the PC.

    3. Open Settings, click/tap on the System icon, and go to step 4 below.

    4. On the right side of Display, click/tap on the display number at the top that you want to make the main display, and check the Make this my main display box under Multiple displays. (see screenshot below)

    Tip   Tip
    You can click/tap on the Identity button to briefly display numbers on your display(s) to help see which display belongs with each number.

    Note   Note
    If Make this my main display and the Apply button are both grayed out, then it means that the currently selected display is already set as the main dislpay.

    Hello aeneas1,

    Do you have "Extend desktop to this display" set for your displays in the "Multiple displays" drop down?

    yes i do....

    this has been an adventure, just when i think i'm getting close i hit another bump... thing is, i use multiple (2) displays every day with my work pc and have never had any prob at all, it's a very straightforward process, but with my new setup it's like pulling teeth....

    speaking of my new setup, it's actually a home theater system as follows:

    windows 10/64, home edition, nuc i5, 16 gb mem.... i've connected the nuc's display port to my 1366 x 768 monitor using a display port to hdmi cable, and the nuc's hdmi port to my 1920 x 1080 tv's hdmi input... i want the 1366 x 768 monitor to be my main display but i just can't make it work, the tv is always the main display... i guess i could try connecting the display port to the tv and the hdmi to the monitor, but that would require some elbow grease given my equipment rack, would much rather do it within windows if at all possible....

    It will be interesting to hear how that works out.

    I assume that you have already tried different connections to the monitor to see if one may work better than the other.

    If you like, you might also see if the program DisplayFusion may work better for your situation.

    Hi,

    I currently use two displays. While this configuration feature works 95% of the time, regularly the boot ends up with swapped content of the screens (main display icons in the secondary, secondary ones in the main, the main display remains the main one) and fewer times with the task bars also swapped (main display changed).

    Like aeneas1, I don't have access to "Make this my main display" (greyed) in the first case even if the "Extend these displays" appears in the combo. In the second case, swapping "main" attribute keeps the icons swapped.

    Will there be a way to lock the configuration [1][2] / [2][1] to monitor IDs?

    Regards.

    Hello Faeldihn, and welcome to Ten Forums.

    The monitor IDs is determined by the port on the graphics card the monitor is connect to. You can swap the connections for the monitors on your graphics card to change them.

    But when using two different connection types, will this still work? Which is the priority connection? I would've thought it would be the VGA, since that is the PnP that is most common, but I use the VGA, as my desktop monitor, and the HDMI to my TV monitor. It's the TV monitor (HDMI) that always ID's as No. 1.

    Yeah, having different connection types won't work like that to change the ID.

    Didn't think so. I just got used to the backward priority, and am living with it.
