There are a lot many types of video connections you can use depending on the available inputs on your TV and the outputs on your PC. That is why I decided to create a list and present each type in detail and the typical applications of each.
Figure 1: Standard video cables:
1. Composite Video (analog) – This is the most common video connection and you can recognize it by its single yellow RCA jack. The disadvantage is that composite offers the lowest video quality. Color and brightness are combined then sent through a single coaxial cable. Most displays have this type of connection as an input.
2. S-Video (analog) – comes with a small improvement over composite. This time color and brightness are sent in two separate signals not one as it was on composite. S-Video cables are made up of two coaxial cables and use a 4 pin Mini-DIN connector. PC video cards and laptops have usually an S-Video connection.
3. Component (analog) – Gets the best video quality over the previous Composite and S-Video types. Now the signal is sent over three separate cables, Red, Blue and Green ( YPbPr ). Component handles HD video.
4. VGA (analog) – VGA was the standard on PC monitors. Many LCD monitors still have VGA inputs but it is not the desired connection for digital displays.
5. DVI (digital) – This digital connection offers the best possible video quality when used with digital displays. DVI is explained in detail here: HERE. More importantly, however, is the ability for one to adapt a DVI output to HDMI which is much more common on HD sets using a DVI-HDMI Adapter.
6. HDMI (digital) – This is the newest type of connection and is created to replace DVI. The difference is that HDMI is a different connector being able to handle audio signals also. HDMI is HD capable and also offers up to 8 channels of HD audio.
7. SCART – is a connection used only in Europe. It is used to connect audio/video equipment trough a single cable. PC’s do not have SCART connections but there are adapters available.
I will also post the Audio video connections soon so keep an eye on the blog and feel free to post your questions for us, I will be glad to answer you all.
