Suppose you wish to
watch a movie or share a slide-show of pictures with your family on
your PC but have a screen that leaves much to be desired. In such a
situation, you can connect your computer to a television screen to allow
your entire family to enjoy comfortably.
There
are many ways in which you can connect your laptop/ computer to a
television. However, the overall video quality will be different for
different methods. You can choose which one to use based on the quality
or the availability of hardware. The
first step is to know what
type of ports and connections your TV and computer have. If you already
know the type of ports and connections available on your hardware,
you can directly jump to Step 2. If not, then the different types of ports are explained in detail below:-

| Different types of PC to TV connection ports |
1)
RCA/Composite: The oldest and the lowest
quality connection available. They are the Yellow, Red and White
connections most of us are familiar with. Yellow is used for composite
video, white for left analog audio and red for right analog audio.
2)
S-Video: S-Video or Super
Video
offers slightly better quality than Composite connections. As it is one
of the oldest type of connections available, most televisions and
computers have it. There are two types of S-Video ports, one containing 4
pins and the other containing 7 pins. This type of connection is used
only for video. So you will need to connect an audio cable from your
computer's headphone jack to the red and white audio inputs on your TV
if you want audio to work.
3)
VGA(Video Graphics Array): Most
computers
and televisions have a VGA port. It offers much better quality than
S-Video and should be preferred if you have a HDTV. Older CRT TVs
however, will not have a VGA port and will require a PC to Television
converter. Just like S-Video, VGA also does not support audio and will
require an additional audio cable.

4)
DVI: Digital Video Interface offers much
better quality than VGA connections. Most laptop computers and HD TVs
will have these connections. Just as the name suggest, this type of
connection can be used only with digital TVs. Also like the previous
two, DVI connections also require the use of an audio cable for audio to
work.
5)
HDMI: The highest quality connections available. Most HD TVs
will have this connection, however, chances are that your computer would
not. If your computer happens to have a HDMI connection port, this
should be preferably used. If your computer doesn't, you can use an HDMI
to DVI adapter to convert HDMI to DVI.
Step 2: Once a common type of port between the two
devices is recognized, you will need the right connector cable to
physically connect them. The different types of connector cables are
pictured above. If you do not find two matching types of connection
ports, you will need an adapter to make the connections type match.
Step 3: After connecting the two devices, on your TV, select the
external input with which your TV is connected to the computer. It may
be HDMI1 or AV1 depending on how you have made the connection. This is
much similar to how you select input from your DVD player.
If you have followed the steps correctly, your TV should now be displaying your computer's screen.
Important: If your computer is not recognizing the external
display, you must connect the TV before starting your computer. If the
picture appears distorted, you will need to change the screen resolution
of your TV by altering the display settings from your computer. Most
older TVs will support only one display resolution while newer TVs will
support plenty of them.
