Here is a quick walk-through and video’s of all the methods that I know to connect a laptop or PC/Computers to your TV or HDTV
1. S-Video – This is probably the most common method out there currently because an S-Video cable is cheap as heck and just about every TV under the sun has a S-Video port. You’ll have to make sure you laptop is equipped with this port. Remember, there are two types of S-Video cables: 4-pin and 7-pin. Most laptops and PC’s are equipped with a 7-pin port, so if your TV only has a 4-pin S-Video port, then this method will not work.
2. VGA – If you have a HDTV, then you will be better off connecting using a VGA cable. It gives much better quality than S-Video and as with S-Video, the cable is very cheap. You usually won’t find a VGA port on regular TV’s though, so this option is if you have an HDTV.
3. HDMI – Using HDMI will give you the best quality by far. This is mainly seen in HDTV and LCD/LED monitors. One of the recommonded way to connect to any HDTV’s to game console, DVD/Blue Ray Players or any Laptop/PC’s. No computers that I know of yet have HDMI ports, but you can get a DVI to HDMI cable to connect it to your HDTV. HDMI is compatible with DVI.
4. DVI – DVI stands for Digital Visual Interface with “digital” being the key word there. The digital signal will give a higher quality picture than either S-Video or VGA. Of course, your computer will need to have a DVI connection and your TV will need to be an HDTV.
