How to Swap Display Identity (Identities)

Thanks for your quick reply.  

So, what if you wanted the HDMI to stay number one?   

That is my issue:   My desktop display is DVI.  (I've also tried VGA).  My intent is to keep this display as number one.  It has no sound, so I use speaker outs.  Remember,  this is display 1.

My second display is HDMI to a big screen.  When this display is off, or is switched to a different input, all is right, the computer does not acknowledge it's existence.

When the HDMI device is switched to the PC's input, the primary screen flashes as it loses sync briefly, and comes back as screen identified TWO.   The HDMI instead of becoming the second screen grabs screen one.  

The issue with this issue is maintaining 'main screen' as make this my main screen. It also affects the audio output in getting the default output to return to the speaker output when the HDMI disappears.  

I might add, that in the several years that this thread has been around,  I have fixed both the default audio and the (make this the) main screen issues.   Still though,  having the screen identity changed along with other defaults without command is what started this thread, and is still the case.

Sooo I switched to DVI-D from displayport on my monitor and now win identifys it as 2 and the tv on hdmi as 1. The old situation as before on my old monitor. 

I suppose there is some internal recognition in windows of the ports. Dont know why we cant manually set the identity of the displays.

Well then, this is the crux of the thread.  Someone on the win development team is supposed to me monitoring these threads.  HEY MICROSOFT!!   GIVE US CONTROL OF OUR DISPLAY IDENTITIES
