2nd display not working

[carljohn]

let me start by saying im an old dog trying to learn new tricks so please keep that in mind. After having my karaoke discs for the time i have and lugging a huge case to my gigs i felt it was time to consolidate.go to a laptop based system and started the process of importing each of my discs to an external hard drive via hoster. Now that i have them imported i have connected an s-video adapter to my dell inspiron e1505, went into control panel, display, settings, highlighted the second monitor (#2) checked on extend my display apply and ok. nothing showed on the tv i use for singers. ive tried going from the s-video to the tv video jack (yellow) and also thru an rf modulator to the tv using cable connector. as i said this is all new to me and i tried reading posts but didnt see (not that one isnt there somewhere) a post. if anyone could please give me a step by step setup i would really appreciate it. thanx carljohn
