How to Swap Display Identity (Identities)

Just bought a new monitor and im using diplay port on it. Win see it as a number one now and the tv on hdmi as number two. As it should.

Hey,

I was facing the same issue. At home, and for me, the main drawback of these wrong monitor identifiers was when I pressed "Win+P" to quickly switch from my PC monitor to my TV : "Computer only" displayed image on TV and vice-versa.

I managed to switch these identifiers, regardless the "main display" used to show icons and taskbar. I think I used the same trick as the registry hack under XP, but through the device manager. Here is my exact procedure :

• Both displays plugged, switch to extend mode.
• In device manager, delete all items (2 expected) under Monitors
• Physically unplug the monitor you want to see numbered 2, or the "projector".
• In device manager, a Monitor may have been added, delete  it.
• Reboot
• Check your PC monitor is numbered 1
• Plug again the second monitor (TV in my case)
• First monitor should keep its number 1

This worked for me on Win7. Hope it'll help !

It certainly is related to ports, but that alone does not answer why it has to be this way at the end user level. At the very lowest level Windows perhaps has no control over how it addresses each monitor, but the whole point of an OS is to abstract low level function to behave in ways the user requires them to. I accepted these limitations with IRQs and such in the DOS days, but I find it hard to accept that there's no way around this using a modern OS.

Is it possible to be a port thing. From what i've read and my personal exp. DVI appears to be second to the HDMI.

May be something like COM 1,2 etc.
