How to Swap Display Identity (Identities)

What type of video card do you have? With an nVidia card you can bypass monitor detection by saving the EDID to a file and locking it in.

I have two monitors and an amplifier. Behind the amplifier I have a TV and the combination actually creates two separate display devices: one being the amplifier by itself with the TV off and the second one being the amplifier with the TV on. I use both since I sometimes use the amp just for music without the TV.

The primary monitor is connected via HDMI, the secondary monitor via DVI. The amplifier uses HDMI.

When I turn on the monitors their ID's are 1 and 2 as they should and in my case they are also in the correct order since monitor 1 is a newer monitor that I use as primary and 2 being older. I extend my desktop between these. So far everything is fine and working as it should be. I keep Outlook (among other things) on the second (ID2), older screen and desktop icons and stuff that I'm currently working on on the first (ID1) one.

When I turn on the amplifier, it takes ID2 and pushes the old monitor to ID3 and this is when everything gets f:d up. I want the amplifier/TV to be duplicated with my primary monitor (ID1), not extended. I can set this up just fine. The problem is that because the old monitor changes to ID3 and the amplifier takes ID2, Outlook and everything else that I want to show on the secondary monitor now wants to open on the primary display that is cloned with the amp/TV (ID2). In some cases this can also f up desktop icon positions (since I have them positioned and grouped manually, not automatically).

I added the old monitor after the others so it is the last device connected. Based on this Windows has decided that it is identified as 3 or 2 depending on the status of the amp/TV being on (takes ID2) or off (frees up ID2).

So what we need is a way to edit the ID numbers as we see fit or at the very least force a specific screen to keep the same ID no matter what we have connected. On my router I've setup a static IP for my computer so that I can connect directly to it from anything, anywhere and also bind traffic rules, port forwarding and so on to that specific IP. Now I want to do the same thing with my screens, I want to route specific stuff to a specific screen, with a specific ID.

And by the way I also use DisplayFusion to automatically do some stuff, like place Outlook always on the second monitor and make its window take up the upper half of the screen. This does not work because DisplayFusion uses the ID numbers to identify the screens. So when I turn the amp/TV on, Outlook pops up on the primary display instead of the older monitor that it should be on.

I have 2 displays and was able to figure this out. I went to display/screen resolution, clicked on the drop down arrow for "display box" which showed 1 and 2 displays, then checked the box "make this my main display" when I selected the other display and hit apply. Voila, however now my mouse won't go across the screens anymore, I have to go all the way left to come into the monitor on the right and vice versa. Oh well!

We can swap displays. The issue we're having is when the display numbers don't match the display numbers of the display adapter. When you click display it shows 1 and 2 but when you click identify in the display adapter software it shows 2 and 1. Make sense?

You can easily fix your problem by dragging and dropping the display icons into the proper position.
