PC to TV

How to connect my PC/laptop to my TV


This might seem like a very trivial thing but can be very frustrating for individuals trying to play there latest video games or watch HD movies on there new 50” LCD TV,

most PC/Laptops will have a VGA connector and/or a DVI connector, some newer laptops and PCs come with HDMI as well.

as a rule of thumb this is the order of preference to use for connecting systems together.



This will carry both HD-Video and HD-audio.



This will carry HD-video only and you will need to find another means

(to transfer audio please see audio connectors below).



This is the same as the previous solution.



This can carry HD-video but in an analog format and is subsequently inferior to digital but is far superior to video leads.



This can not be used on a pc/laptop as I’ve yet to see a PC or laptop with a SCART plug.


Video/Audio to SCART:

This will connect both 2Channel audio and SD-video to your TV.


Composite to composite:

This is by far the cheapest option but only gives SD-Video.


VGA to TV:

This is a separate device that converts a PC VGA signal to an analog composite video signal.


VGA Connector

– Video Graphics Array



-Most people set the  resolution to 1024×768-XGA

-Maximum 2560×1600

this is found on most PCs and laptops, and some LCD TVs as well it is the most common video connector on PC/Laptops and carries an analogue video signal.


HDMI  Connector

High-Definition Multimedia Interface

-The latest version is HDMI Version1.4

-This can carry  Full-HD (1080p) but is also dependent on the device

-Maximum 4096×2160

-Caries both HD-Video and HD-Audio

-This can be found on most new LCD TVs but just because the TV says its HD does not mean it automatically has this port so please check when buying a HDTV. Most new graphics cards and top end laptops also come with this port as well.



DVI Connector

Digital Visual Interface


-DVI is compatible with HDMI and can be easily converted however DVI does not carry audio by default


-Maximum resolution

-Single: 1,920 × 1,200 @ 60 Hz

-Dual: 2,560 × 1,600 @ 60 Hz

-The pins by the flat connector carry analogue signals so this plug can also be converted to a VGA as well but not visa-verse but please check whether you have these pins as not all plugs come with them.

-These are found on most new graphics cards and some laptops and also some LCD TVs.


S-Vidio Connector

Separate Video

-This is an analogue signal that carries the chroma (colour) & luma (Picture) down two separate lines which improves the video quality.

-This cable does not carry audio.

-Resolution interlaced  480 or 576

-It is found on lots of TVs both LCD and CRT(Box TVs) as well as some PCs and Laptops.


PS2 for mouse/ keyboard

PS2 Connector


This is a PS2 plug socket used to connect keyboards and mice to a PC or Laptop. I feel I need to place this connector here as it gets confused with the S-Video connector the easiest way to identify this plug is the notch in the middle.


Comosite Video Connector

Composite-video(Composite Video, Blanking and Sync)


-Like the S-video however both the Chroma & luma are sent down the same signal and separated internally in the TV with filters this reduces the signal quality.

-The signal is made out of 3 composite sources Y, U and V

-Resolution interlaced  480 or 576

-This is a very common connector and is usually accompanied by either one or two other phono sockets for audio



SCART Connector

Originally a French TV standard, now it is common across most European countries-     This is an analogue connector and caries both audio and video signals the video signal also comes in a RGB standard as well as composite, it has been revised to carry S-video as well.

-Resolution interlaced  480 or 576

-This is found on nearly all TV sets and other video equipment in Europe


RGBHV Connector

This connection is capable of carrying analogue HD usually from a VGA connection on a TV.

Note that this requires 2 additional connections(H,V) for the horizontal and vertical sync pulse


Display Port

Displayport Connector

This is a royalty free digital display interface


-Max resolution 3840 × 2160

-Found on a few laptops and Graphics cards as well as a few LCD computer displays

-This can carry 8 channel  PCM audio as well

In the image above you can see what connections are compatible with each other and what connection will need another device to convert the signal from one type to another.
