VGA-HDMI cable

It may seem like a good idea, a VGA-HDMI cable, at first glance seem to buy. But unfortunately this is not the case. These cables simply do not work, can not work. The solution, which are necessary to connect a computer to an HDTV is much more complicated. A passive cable can get the job done, so that we can for a solution to translate the signal must actively seek power.

The problem is that an analog VGA, and HDMI is a digital signal. An analogThe digital conversion requires an active process that every bit of information transmitted and translated from the range of values ​​to a combination of ones and zeros, which can be understood by the end of the cable HD receiver currency.

The other problem that the transformation is presented that an HDMI cable with audio and video signals on the same line. VGA carries only video signals. Although we can use a cable to pass between the two types of port, we would get left behindComputer station.

The real solution is probably using what is called a VGA converter box HDMI. The box for the cables of both types (in general, the input audio to accompany the video, only the signal from the computer) and converts the separate audio and video signals related to a digital signal that is transmitted via the HDMI cable can . There is some loss of quality, but overall it is the best solution is really there because you can find different types of cables for use.
