    If you want the number to be different from what it is, you are going to have to plug your TV into a different port on the Video card. Wouldn't it just be a lot easier to switch which one is set as the Main display though?

    People like you are why problems like this are never fixed lol.

    We'll leave it at that.
    OK, refresh me will you what is that actual problem? Why does it matter that the TV is shown as monitor 1? And what issue that you can't solve does it create? I honestly want to help? I just don't see why your fixated on it being labeled as Monitor no 1.

    What you are saying DOESN'T change the fact the in the Win+P menu the secondary display is always in fact the main PC monitor (Yes it's been ticked as the main display in display properties) and the Main PC is my television (tick box for main display empty)

    I could change the ports theoretically but there is only one HDMI on my GPU and even on my previous GPU that had multiple HDMI the problem was exactly the same.

    Well the problem is you don't understand and clearly don't want to so you should of just not bothered responding the first place. I've said from the very beginning its not a functionality problem but an aesthetic one. I linked you to another thread where the 'problem' was addressed clearer but you don't seem to have acknowledged that..

    Ok I see the EDIT, and the link added to the first post, didn't see it until just now though. Following that link shows this post.

    This has nothing to do with which is marked as my main display. Yes, my Acer is marked as my primary display in the Screen Resolution control panel, and it even remains the primary when my TV is hooked up, but that doesn't stop Windows from identifying the Acer as monitor #2. Declaring which monitor is your primary doesn't affect the numbered identity.

    Isn't that what I've been saying?

    The link was posted on the second page but you ignored it, I edited into the first post after to make things clearer.

    If that's all you got from the link then something must be wrong with your browser..

    You kept going on about it being the "main/PC display". And I've been telling you, just because its labeled as 1 doesn't mean its the main PC display. Any display can be the Main PC Display. If you had stated from the very beginning that all you want to do is change the number this could have all been avoided. Plug it into a different Port and its number will change.

    What monitor is defined as your main monitor is based on the port it is plugged in on the GPU. You have to figure out which port is zero (0) on the GPU that is going to be the main monitor.
    What is the source of your information on this ("which port is zero (0) on the GPU that is going to be the main monitor"). Is this just the way you think it should be or can you provide a reference to what this is documented?

    On boot up, the video card decides what monitor is main, the one the BIOS POST and boot screen show on. It's coded in the video cards firmware. If I connect 2 or more monitors to my Video card my BIOS boot screen will always show on one specific monitor. I have no control over that. The video card decides that based on how many monitors are connected and where they are connected. Once Windows loads I can set any of the three monitors to be the Main Monitor in Windows. Even then, that will not change what monitor shows the BIOS POST screen. I know this from observing what happens with different combinations of monitors connected.

    You're not understanding the issue the OP is asking for a resolution to... I stumbled in from a Google search so that lead me to this thread where I've read it all to see if a solution was found and all I got was you constantly telling the OP they are wrong... They aren't...

    Additionally, the monitor your UEFI shows up on has no bearing on what monitor Windows will mark as your "Monitor 1". My board boots with my UEFI showing on my primary screen, but Windows considers that same screen to be "Monitor 3" so it isn't the screen selected if I use Windows + P and set "PC Screen Only", but it will show if I select "Secondary Screen Only" (entirely skipping over "Monitor 2").

    The issue is simply this:

    Is there any way to determine what screen is set as the "PC Screen Only" and "Second Screen Only" when Windows + P is used for fast display toggling?

    PC Screen Only appears to be set to "Monitor 1" with no way to change this...

    "Make this my main display" has no correlation to what screen Windows + P "PC Screen Only" will use.
