TV Cables Buyers Guide
The choice of TV cables seems to be getting ever more complicated. The frustration and confusion in purchasing TV cables is only exacerbated by the knowledge that the wrong choice of cable will mean we are not getting the full potential from the wonderful TV on which we have just spent a fortune.
For a classic coaxial TV aerial cable, the most important thing is to ensure you get the correct "gender" for the connection. To connect your wall socket to the first device you will require a male-to-male cable. However, for connections between devices (e.g. Freeview box to TV) you are likely to require a female-to-male cable. You should also estimate how far your TV is away from your aerial socket and buy the shortest cable possible. Not only will overly long cables cost more, but they will reduce the signal quality as well as being unsightly and difficult to manage.
For connecting devices such as DVD players and VCRs to your TV you would historically have required a SCART cable and many devices still use this form of connection. However, you are now more likely to be wanting to make HD (high definition) connections between devices such as Blu-Ray players and games consoles with your TV. To do this you will require TV cables that support an HD signal. The solution of choice for this is the HDMI cable as it supports standard or HD video, as well as multi-channel digital audio through a single cable. Alternatives to the HDMI cable are DVI cables and component cables. Selecting a DVI cable can be difficult as they come in DVI-D (digital), DVI-A (analogue) and DVI-I (digital and analogue). You will require DVI-D cables if you are using them instead of HDMI TV cables as you will be connecting digital devices. Note that DVI cables do not support any audio channels, so you will need an additional audio cable for sound. You may require an analogue HD connection to your TV (for example for some games consoles), in this case a component cable can often be used. Component TV cables consist of 3 or 5 coaxial cables. Three will be for the video signal (RGB) and the additional two on the 5-cable version are for two audio channels. If you are only using 3-cable component then you will need an additional cable for the audio signal.
