Steps
1
Assure the component you want to hook up has a "S" video output as well as making sure your TV has an "S" video input/s.
2
Purchase a good quality "S" video cable. Most components have one included, but they are typically not of the best quality. One with gold plated connections is best. They can go for $20 and up.
3
Connect "S" video cable from component (Digital TV Receiver, DVD, Game system and etc.) directly to your TV.
4
Do not connect any other video cables. Connecting any other video cable will override the digital "S" video signal and it will be useless. It is a popular misconception that connecting more cables is better. It is not. Many instruction pamphlets will advise to connect all cables. Don't You Believe it!
5
Turn on your digital source and TV and see what you have been missing. Your quality of resolution will increase anywhere from 20 to 80% depending on how you had things connected in the first place.
*Once the hardware / software is recognized > Control Panel > Display and you'll see in the left hand task bar, "Change Display Settings". At this point most systems you can duplicate, clone or mirror your desktop or craptop and adjust resolution so on and so forth.

The same basic principles apply to an HDMI cable.
