How to Choose the Best Monitor Cable with Ferrite Bead
A ferrite bead is a passive electronic inductor, commonly found attached to the power cord of your laptop or on your monitor cables. While most people are aware of what a monitor cable is and what it does, the ferrite bead that is attached to it is a bit of a mystery. Not there for show, the ferrite bead is designed to inhibit high frequency signals on almost any power supply line. They can be used for fixing the disturbance known as EMI (electromagnetic interference). EMI is generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. Below you can find some helpful information on selecting the best monitor cables with ferrite beads.
When shopping for a monitor cable, experts suggest choosing the VGA monitor cable as they will typically come with a standard but efficient ferrite bead. The VGA monitor cable enables users to connect to various devices including a desktop display, TV set, and a projector (when an HDMI or DVI connection is impossible). While looking at the different selections available in the market, it’s best to determine the length that you want and that you think will suit you best. Note that the shorter your cable, the less likely you’ll have to deal with your video signals losing quality. If possible, choose the shortest one that would suit you so long as it protects from signal interference.
Other tips for selecting the correct VGA monitor cable is to purchase quality material. For example, you’ll want to choose a cable that has pins coated with gold. Gold makes for a much better conductor than its counterparts that are coated with copper. With a better conductor, you can ensure faster data transfer and stronger signals. Another way to guarantee that your cables will provide signal interference protection is to purchase the cables that have multi layer coats of shielding materials. The materials ensure that RF or EM signals do not disrupt the transfer of data occurring in the cables.
