HDMI (High-Definition Multimedia Interface) will give you the best quality picture on a HDTV. You can buy a DVI to VGA adapter to convert between a DVI output and VGA input, etc. The reason why DVI became popular is because it supports analog connections also, namely VGA. Also, DVI cables to do not support audio either, so you still need a separate cable for that.ĭVI cables are also a bit complicated as you have DVI-I (Single Link), DVI-I (Dual Link), DVI-D (Single Link), DVI-D (Dual Link) and DVI-A. DVI cables used to be expensive, but now you can get them for $5 to $10 online.
Of course, your computer will need to have a DVI connection and your TV will need to be an HDTV. The digital signal will give a higher quality picture than either S-Video or VGA. DVIĭVI stands for Digital Visual Interface with “digital” being the key word there. VGA cables do not support audio, just like S-Video cables.
Also, as with the S-Video cable, VGA cables are very cheap. In terms of picture quality, VGA is bette than S-Video. Most desktops still support VGA and have VGA ports on the back. Again, you’ll still find the port on HDTVs and monitors, but not on laptops. VGA, like S-Video, was another common port found on all laptops and TVs/computer screens back in the day.
