In this article, we will show you how to connect your laptop or desktop computer to the TV , to bring all your content to the living room of your home with ease and enjoy them with your own.
Let's take as a reference for our tutorial laptops, and portability issues that are often connected to the television. However, we will give you tips that are applicable to a desktop PC or a mini computer , as they have almost always with the same outputs for video and audio .
Inputs and outputs
As recently we tried a similar case when connecting a laptop to a monitor to make it our home screen, you just refresh your memory : the first and most important element is that you have to check the video input and output for to the computer and television respectively.
In some cases , a cable with the appropriate endpoints will be enough to carry the signal to the television equipment , in others also need a converter to reach its destination correctly.
First let's see what are the most common video outputs :
S -Video
Also known as Y / C connection is a standard signal that carries a double : luminance and chrominance . It is very common on all televisions and computers, and requires very little outlay : a simple male / male cable for the video signal , and a dual RCA ( the typical red and white) for audio. Its image quality and resolution have become obsolete televisions the past ten years .
VGA / miniVGA
This standard connection both screen resolution and appeared in 1988 but remains in effect today in certain areas. In TVs, which is what interests us, is insufficient for HD monitors but applies to the rest . MiniVGA version has the same features but the socket was reduced to optimize space on laptops .
DVI
It was the first standard analog video interface not and although not as widespread , best meets the purpose of sending the signal or TFT monitors , as is the case , a digital TV screens . The main advantage of this connection is that it exists in three variants to suit any TV : DVI -A , which sends analog signal such as VGA , DVI - D , which does the same with the digital signal, and DVI -I, sending both types simultaneously. The latter is the one that usually comes integrated with laptops graphics cards , allowing you to connect to a TV signal without digital input via a DVI to VGA adapter .
HDMI
It is one of the newest and fast connections to implement, and has become the de facto standard today for HDTVs . Improvement over pre- integrated in one cable video signal and audio, and makes it easier than ever to connect your laptop to the television. But only Full HD TVs can really take advantage of the image quality offered, and only the latest portable series integrated lead him .
DisplayPort
Emerged in 2006 by convention VESA (Video Electronics Standards Association) , this connector lives as competition, while in addition , the HDMI standard. Like this one , simultaneously carries sound and picture signal , and has established more in the field of computers in TVs. As added , mentioning that there is a smaller version called Mini DisplayPort , which is listed as the only video output possible in all Macbook and Macbook Pro laptops , iMacs and Apple brand .
Regarding the input connections, besides those already mentioned as video outputs , there are some more typical formats of televisions are still used
Composite Video
One of the oldest video connections , which offers a rather poor quality LCD TVs , but it is still used in cathode ray tube TVs , ie in the old analog displays . Many know him as the head yellow cable into the RCA cluster of three , which also includes the red and white for audio.
Component Video
Some TV models had a more advanced analog connection that the only video composite cable . In this case , the video signal comes through three wires red, green and blue , which have different combinations of luminance and chrominance in order to display an image of better quality. There are two types of signal : RGB and YUV , but both have the same input on the TV .
SCART
Better known by all as the SCART cable , is standard on all television for almost twenty years. In one cable carries the audio signal and video, but it has steadily become obsolete by its low resolution , in favor of other formats like HDMI . Curiously, it was a standard imposed by law in your country of origin, France, but ran extending even into the Asian market .
connections
Having said all that , we could be lecturing on the possible combinations of cables, adapters and signal converters to cover all types of inputs and outputs. However, for convenience , we have prepared a table attached that collects and offers simple solutions and easy to find . In this table we have considered the cases worth pointing out , ruling in turn those who lose too much video quality.
The solutions we offer are divided into three categories : straight-through cables , such as those that carry the signal between inputs and outputs of the same type of signal adapters that convert between types , sometimes with some loss of quality by the way and finally, by processing converters , which usually take the form of signal encoders . The particularity of these is that they require signal processing by completing and expanding its information to conform to the format required by the TV input. This is what happens , for example , when you want to convert an S -Video signal to VGA .
In some cases , the connection between formats is not simple and requires several steps , ie first convert the signal to a format and use another adapter to convert it to a third party. Should know that these conversions are losing quality , so you have to avoid them unless absolutely necessary.
All solutions presented here can be found in electronics stores, both traditional and online shops . There are many cables and adapters brand , making it difficult to choose one , but of course, always seek to offer a minimum guarantee of use .
We hope that with this information you may have clear the process to connect your laptop or desktop computer to TV and watch movies or TV in the comfort of your couch , either Boxee or any other player application .
