How to change monitor assignment in a dual monitor environment

I have two monitors attached to my Windows 7 computer - a viewsonic monitor and an panasonic plasma tv.

Before I installed the tv - my Viewsonic sonic was the primary monitor. However, for some unknown reason - when I connected my Panasonic plasma tv to my video card - Windows made the TV as the number 1 primary monitor and my viewsonic as the secondary number 2 monitor.

How can I get Windows 7 to reverse those assignments? I want my Viewsonic monitor as the primary, number one monitor.

When you rt click the desktop and select Screen Resolution, you will be presented with a window showing the two monitors, simply click/hold one of the montors shown and drag it to the required position.

There are also other options, eg Identify, and Display, use the drop down to select the display (monitor) to use as the 'main' display (Some options only impact if you are using Extended Display and not Duplicate display

    This post doesn't actually answer the users quandary.  The user is specifically looking to change the device assignment of monitors in a multi-monitor environment.  This is necessary because several products use these identifiers when resolving how to display certain data (web applications, ProFx and Go To Meeting specifically).

    I believe this has something to do with the values and objects in the Hive Key HKLM\Hardware\DeviceMap\Video,  I have not had the chance to modify these as of yet.

    Furthermore, Microsoft really needs to do a better job of moderating these posts to remove erroneous and/or inapplicable answers.  Especially when it only takes one person to "Find this useful" for it to suddenly become the top answer.

    Hi Matthew, in the 3 years since you've posted this have you heard of, or found, any resolution for this issue? I started my own thread here: http://bit.ly/1EwqJdu, but no one seems to understand the issue.

    Hi.  Have you tried my suggestion to use a modified adapter with the auto-detect pin disabled?  (Three posts up - May 11, 2014.)
