How to connect a laptop to a 47inch lcd tv

You can't hook you TV to the monitor itself, rather the computer.
If your PC has a wide white connector (DVI) that is supplying signal to the monitor, you could use a DVI to HDMI adapter cable to connect your PC to your TV. This is also possible if your PC uses a small blue connector with 15 pin holes (VGA) by using a VGA cable to connect your PC to your TV.

dear user,

if u connect it with vga cable. den kindly change vga cabel and ask for 15/15 pin active VGA cable

You need to set your laptop video resolution to the native resolution of the TV, it is too high right now for the TV to display.

I have a LG plasma and I am trying to connect my PC via VGA and I am getting the "Invalid Format" - can you please tell me what is the problem? Thank you

Turn Off Your TV and Laptop before connecting the VGA cable. Turn them on after you have connected both. 

Hello,

This should help you. I think Chris Duckworth said it best. "sounds to me like your refresh rates or resolution may be set too high on the XP machine."

Go to this website to get the rest about setting up your tv as a monitor. Type invalid in the word search to get to the relevant section.

You may need to use the S-video cable for video. Make sure video mirroring is disabled on the powerbook. Also, make the external monitor the primary display by dragging the menu bar to it in Displays preferences (Mac OS X) or the Monitors control panel (Mac OS 8 and 9).

The video out resolution through the port may not match what is supported by the TV.

Every laptop has at least a VGA (computer video connection) and s-video cable port. A VGA cable is preferred if you want to be able to read text on your LCD TV. Check to make sure that your LCD TV has a VGA connector. It's a port that accepts a 15-pin connection so it's pretty easy to spot if it's there. It's just like a computer monitor cable if that helps. Should be able to find it at any local retail store that carries computers. VGA or RGB cable.
