Need help setting up dual monitors

[ThatsAgood1jay]

Hi, I am trying to set up my hdtv to take in a computer signal with nview. I am using a Viewsonic vx2025 as a primary monitor, and a samsung 32" 720p hdtv as a secondary monitor. I am trying to set them up in dual view. Everytime i switch the hdtv over to the PC input, it will say that it is searching for signals, then the screen just goes dark. While the screen is dark, a red dot, that usually signifies it is being turned on or off. Is blinking. I hhave tried everything i can think of, but it is still not working. '

I am using a DVI cable with a DVI - VGA converter to plug into the tv

also, how do you tell the difference between a dvi-d, dvi-a, and a dvi-i cable?

Perhaps using the hdmi input would be better.
