Try configuring your display settings on the laptop before connecting. I have a HP dv7 and it was doing the same thing until i configured it for a secondary display

How can i connect my dell inspiron 1721 to my tv samsung led


If your Samsung TV has a VGA input then connect a VGA cable to the TV and the other end of this cable to the video port on your Dell laptop. Turn on your TV and select the VGA (computer) input then boot up your Dell laptop.and then the video data from the laptop will automatically divert to the TV.
You can toggle between the TV and laptop LCD screen by holding down on the Fn key and press the F8 key.

I have a dell inspiron (600m) andi also have a dell flat screen television. i used to be able to connect my laptop and tv, so the tv would become a flatscreen. i would go to VGA and my laptop would appear....


I assume you would switch the TV's source to VGA. Is that correct?

Connect it the same way you did before, with the VGA cable. Then hit Fn + F8 on your keyboard, to switch the signal from your laptop screen to the VGA cable. Then select VGA as your source on your TV as you did before.

If that does not work, please post and tell us what type of television you have.

If your dell is equipped to do this it is on the back side and appears as a video card connector or s-Video out. It is possible that your Dell is not equipped to make this connection, I have found a few that are not.

Dell Inspiron 2200 to Phillips 47 " TV


check this out http://answers.google.com/answers/threadview/id/762913.html *A VGA connector and cable are used to carry analog video signals plus display and graphics data. The VGA is a 15-pin connector commonly found on laptops and other devices. With this port you need a PC-to-TV Convertor to connect laptop to TV. You simply plug the VGA cable from the source into the convertor, and use an S-Video or RCA cable out to the TV. The converter is USB powered, so there’s no external power adapter to carry around, making this laptop to TV connection entirely portable. you will need a seperate audio cable unless you are going to use your laptop's speakers

I dont believe that you can hook that model up to a TV you have to have a certin video output and it also would depend on your tv as well. But i am about 100% sure that series does not have the output you need you usally can connect via S-cable
