Dual display error

[joe's jams]

Thanks for the help everyone. It seems that I'm going to have to start all over. I have to get the correct video card and then take Hoster off the computer I have it on now, and load it onto another computer. I checked and I have a computer that has a 40 GB hard drive running an Intel Celeron processor with a speed of 1.2 GHZ. It's operating system is XP PRO. The only problem is that I'll have to update the RAM. It only has 256 MB. Thanks again, I sure hope all this is worth the time and effort.
By the way, my singer's monitor is a TV monitor.
