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

    I don't think you can even after three years. Here's one workaround for KVM switches that might apply to your situation.

    1. Buy a cheap M/F adapter and on the adapter disable the auto-detect pin - for VGA remove pin 12 with needlenose pliers, for DVI remove pin 16, for HDMI tape over pin 19. 
    2. Unplug the TV so windows automatically makes your monitor #1.
    3. Reconnect the TV using the modified adapter and it should not take over the #1 assignment from the monitor.

    For HDMI the tape trick is not necessarily destructive so you don't really need an adapter. For VGA and DVI you could do this on your original cable if you don't mind the risk of messing it up. You can search the web for more details on all of these.

    This technique is mainly to prevent dynamic reassignment when using KVM switches but it's worth a try in your situation. At least this way the monitor and TV shouldn't be reassigned dynamically so once you get the assignment you want it won't change.

    Please let us know if this works.

    Thanks a bunch for taking the time to reply.

    I've come to agree with all your conclusions.

    Will learn to work around what is really a minor inconvenience.

    Thanks again.
