A VGA cable can be used to transfer the video signal from an output source such as a Laptop to an LCD screen. Remember that VGA cables only transfer the video signal, not the audio signal as well. All electronic devices give off electromagnetic interference and many devices such as mobile phones also emit radio frequency interference. To stop the VGA cable being affected by these emissions, it features a high density suppressor which filters the signal. This prevents data loss from the cable and increases picture quality. The connectors now have 14 pins (not 15 like in the picture), as pin 9 is never used any more.
