How To Connect A Laptop To A Tv

To many people connecting their laptop to a TV can be a bit daunting but there is no need for it to be so

. Probably the hardest part is figuring out what connections they have available on their TV and laptop then getting a suitable laptop to TV cable.

Here we will offer some advice in working out what connection options you have, while we cant come into your home and tell you we can describe what connections there are and offer some pointers for each one.

Older equipment / non high definition will often use one of the following cables:

RCA cables or sometimes known as Phono leads were very common a few years ago using three round coloured connectors and used to transmit analogue data. The three connectors are yellow for video, white for the left channel audio and red for right channel audio.

S-Video cables or Super Video is still popular and consists of a round connector with between 4 and 7 pins for the video signal and two audio cables for the left and right audio channels the same as RCA.

Scart Cables are rectangular in shape and have 21 pins in two horizontal rows. Commonly used on European TVs and are capable of transferring both audio and video signals in standard definition. Now of course they are outdated and if your equipment is modern it is unlikely to use them.

VGA cables commonly used on older laptops and desktop computers and are a 15 pin connector and have a rounded rectangle shape. The VGA cable is only capable of transferring video information for audio you will normally have to use RCA type cables.

More modern equipment such as digital and high definition will most likely use one of the following:

DVI cables are rectangular in shape and have three horizontal rows of 8 pins giving a total of 24 pins. These were the standard connector for digital video until recently with the advent of newer and faster technologies.

HDMI Cable is now the standard for digital connections and used for watching HD TV etc... They are rectangular in shape and about half the size of a DVI connector having only 19 pins in the connection. One of the advantages of these is that they can transfer both digital audio and video.

DisplayPort Cables have been specifically developed for connecting computers to their displays and to home entertainment systems and allowing the transfer of High definition data both audio and video.

Once you have figured out what connections you have available to connect a laptop to a TV you can take a look at what options are available. Dont worry if your laptop and TV dont have the same connections types as there are a number of ways of converting one to another available. A good cable & lead supplier will normally be able to offer you advice if you are still unsure what you need to get the job done.
