The 15-pin VGA connector was provided on many video cards, computer monitors, laptop computers, projectors, & high definition television sets.

When you have a cell phone or other device charging from your vehicle’s 12V accessory outlet, you may notice that the radio station you’re listening to has more static than normal. This is most likely caused by electromagnetic interference or EMI for short. EMI is generated when an electric current is running through a cable thus creating a magnetic field; this is what distorts radio waves. Depending on the distance between your vehicle and the radio station’s broadcasting tower, you may not experience any static at all, or it may completely ruin an already weak signal. Other similar examples of how radio signals get distorted by EMI are when you’re driving next to high-voltage power lines, or if your vehicle’s radio antenna is built in to the rear windshield and you then turn the defroster on, ie 2008 Honda Civic.
