VGA to HDMI Cables

VGA to HDMI Cables

Hdmi

Loves to be like a good idea to buy a VGA to HDMI at first sight. But unfortunately this is not the case. These cables simply do not work, can not work. The solution you need is a computer connected to a high definition TV is much more complicated. A passive cable is not able to do the job, so we needed a solution that can be translated based on an active aspect of the signal.

The problem is that a VGA signal is analog, whereas HDMI is digital. A similardigital conversion requires an active process that evaluates each bit of information passed and translates it from its range of values to some combination of ones and zeros that can be understood by the receiving end of the HD cable.

The other problem that the conversion presents is that an HDMI cable carries both audio and video signals over the same wire. VGA only carries video signals. Even if we could use a cable to go between the two port types, our audio would get left behind at the computer station.

The real solution is probably to use what is called a VGA to HDMI converter box. The box accepts cables of both types (usually plus an audio input to accompany the video only signal from the computer) and converts the separate audio and video signals into one cohesive digital signal that can be carried by the HDMI cable. There is some loss of quality, but overall it's the best solution that really exists unless you can find different cable types to use.
