Notebook HDMI have what use

Problems added: notebook HDMI have TOSHIBA Dynabook Satellite T20 173L/5 Battery what use, notebook HDMI and VGA interface have what distinction, that a better interface, HDMI and VGA interface can be mutual conversion?

The answer: HDMI interface is a kind of new hd video transmission interface, support the HDMI with such as liquid crystal displays or external LCD TV equipment such as price than does not support higher than some of the HDMI,TOSHIBA Dynabook Satellite T30 160C/5W Battery HDMI video support in high definition will be far better than VGA, early VGA interface even 1920 * 1080 resolution are unable to support.

But now the laptop graphics CARDS technology promotion, VGA interface can also support 1920 * 1080 resolution, but in the quality of the image transmission was surely not the HDMI, and at the same time for high resolution refresh rate problems,TOSHIBA Dynabook Satellite T30 166E/5W Battery such as some 3 D movie screen format requirement can be 120 Hz refresh rate, but with VGA interface'm afraid I can't reach, HDMI and VGA about the conversion of the mutual conversion problem, can achieve through adapter, but as a result of two kinds of technology, after converting is just to solve the problems in the interface on, in turn VGA quality whether HDMI and VGA or turn can only achieve VGA HDMI standard..

The above is the image problem, HDMI another characteristics is the sound signal and image signal integrated together all transmission, which means that if the use is to have a HDMI notebook, unless you need to use TOSHIBA Dynabook SS M35 166S/2W Battery common audio interface, otherwise can't separate use audio interface. HDMI output graphics CARDS are support built-in independent audio chip, and on the main board of the audio chip is different sound card, the two can separate Settings.

Suggestions in laptops to buy it if you can choose to have HDMI notebook, so in external equipment may use.

The following simple example of a HDMI application:

And compared to the desktop, laptop computer TOSHIBA Dynabook TX Series Battery in the performance of the gap has more and more small, but of liquid crystal screen display size but fell far cannot and compared the desktop. On the other hand, with the big screen LCD TV gradually came into thousands of families, a new application forms and quietly popular computer-the sitting room, also named HTPC.

The biggest advantage is can HTPC network downloaded movie, TV output to admire the liquid crystal TV, equipped with large size, and the width of the screen LCD TV, the mainstream of the video show will be opened to the effect of shocked me to present in before the user, the laptop LCD screen viewing experience is that not possible.

We need to do is to video signal and audio signal output to the liquid crystal TV respectively, below we come to TOSHIBA Dynabook TX/3514CDSW Battery talk about video signal first. At present, can achieve good image output interface including VGA and HDMI (S terminals, DVI has faced out). One of the most common VGA interface, but it can only transmit analog signals, quality of the quadrature can only say, suitable for the hd video broadcast (that is, the network of the most common RMVB format movie).

And now has HDMI notebook have mass listed, the user TOSHIBA Dynabook TX/66E Battery can directly through the VGA or HDMII to achieve video output, at this time, we also need to set the audio signal output to LCD TV. End of shuttle notebook earphone interface, the other end of the connection mode and divided into several, depending on the liquid crystal TV corresponding interface type, but related cable are easy to find.
