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 does not resolve the problem with windows considering the TV to be #1. It forces your "2nd screen", your monitor to be set as main display. But the projection settings are then set to " show only on second display " for instance if you only want to display the picture on your main monitor.
I had this problem where my primary monitor was plugged into the DVI port on my GFX card and my secondary monitor was plugged into the DVI port on my motherboard - the secondary was coming up as number 1 and primary as number 2.
It ended up being a BIOS setting that fixed it - I noticed that BIOS loaded up on the secondary monitor so the problem couldn't be Windows specific. I had a look the various menus and found there was a setting to force the BIOS to make the monitor plugged into the GFX the primary, rather than let it sort out which monitor was which automatically. Once I did this, Windows followed suit. For my BIOS (Asus) it was: Change to "Advanced" mode -> Advanced -> System Agent (SA) Configuration -> Graphics Configuration -> Primary Display, change Auto to PCI-E. I also enabled iGPU but I don't know if this did anything.
I realise not everyone here having problems has the same set up as this so this might not solve it for them, but it's worth a shot if you do.
Sorry, but this procedure has been tried (and it fails) by thousands of people over the past many years.
Upon execution of the step 5, Windows instantly changes the monitor #1 designation back to where it was originally.
