I just set up a new HP computer with Windows 7 a couple days ago and everything went as normal. My previous computer had a dual monitor setup that I had installed, so I purchased a new video card for my new setup and connected everything, but now my main monitor doesn't come on at all and only the second monitor comes on and acts as the first monitor. I have checked and re-checked that everything is connected and it is. When I open up the "appearances" section for the monitor, there is only one monitor shown and of course it's shown with the big Number 1. No matter what I do, I cannot locate a 2nd monitor. This went so smoothly with my old Vista computer and this one is frustrating me. Your help will be appreciated. Thanks.
