vga cable

Hi everyone.  I am trying to attach my notebook pc to my lcd hdtv using a vga cable.  I did attach it to my tv, but the screen is blue.  Is the vga cable no good?  What am I doing wrong?  I have a Inspiron 1501 with windows vista as the operating system.  Any help with be appreciated.  mary.cell phone spy more about cell phone spy.... cell phone spy software
