"Necessity is the mother of invention" - by the ancient Greek philosopher Plato
No, I didn't invent anything over here. While in the process of setting up a home entertainment system, I preferred not to buy anything in haste. In India, the home entertainment portfolio is under major revamp now. LCD's and Plasma's are entering the home entertainment market in a big way. The prices of the TV's and home theater systems are crashing down.
In the meantime, to enable me watch my favorite movies, I was in need of a stop-gap solution. I thought of using my laptop as a DVD player and connecting its video-o/p to the TV. The following are the steps to connect Dell Latitude D600 laptop to Sony 29" CRT TV.
What you need?1. Dell S-Video to Composite TV out adapter. (You get this adapter normally with the laptop)

2. Composite video cable (You can purchase one from your local electronics store)
How to connect?1. Connect the S-Video to Composite TV out adapter in your laptop S-video output.
2. Connect one end of you composite video cable to the S-Video to Composite TV out adapter
3. Connect the other end of your composite video cable to your TV video input
4. Switch the TV to appropriate Video mode
5. Boot your laptop
6. Go to Control Panel > Display > Setting tab (Win XP OS)
7. Right click 2nd display and attach it.
8. Set the resolution and color properties. (Generally the TV supports 800x600 resolution. Sony 29" TV supported 1280x780 resolution with 32 bit Color)
9. You will see the extended desktop.
The TV screen behaves like a extended monitor. Drag the applications you want to run into the TV screen.
This way you can run movies from your laptop on to your TV screen. In order to get your audio output into your TV, you need to take the audio out from the headphone-jack in your laptop to your TV audio input.
P.S: It is imperative that you get a properly insulated composite video capable. Otherwise when you connect the power chord to your laptop, you shall get electrical noises in your video signalLinks:Dell DocumentationHP India site documentationS-Video site
