GLOSSARY

The 15 pin VGA should be pretty much known to everybody owning a PC monitor. The picture information (RGB and horizontal/ vertical synchronization) is transmitted analogously.





Analog transmission of high frequency video signals through a conductor is subject is rather interference-prone. What adds to that, is the fact that the longer the conductor is, the more the signal quality declines. These factors result in variations or respectively in loss of selectivity of the video signal. Since there is no redundancy this can't be compensated - even with the best of electronics. For this reason one should mind to only use D-Sub cables that are high in quality.


The D-Sub connector is often found on LCD TVs and can be used for connecting a PC.
