So what are directional HDMI cables? Directional HDMI cables are more advanced than regular HDMI cables. This is because they include built-in equalizers, amplification, and filtering. Directional HDMI cables are designed to help carry signals over longer distances. Directional HDMI, however, relay signals in only one direction.
Most directional HDMI cable manufacturers include an arrow icon directly printed on the cable itself. In fact, listing the full capabilities on the cable itself is considered an industry standard. However, this is optional so make sure you check the specifications before you purchase any HDMI cable.
What Is An Active HDMI Cable?
Active HDMI cables are those that have an “active” digital equalizer built directly into the cable. Often indicated by a bulge in the wire itself, these equalizers help to strengthen the signal flowing through the HDMI cable and enhance capabilities.
Improvements in technology means your HDMI cable is able to handle more than it has previously. RedMere technology is just one example of the enhancements companies have made to the standard HDMI cables we use today. Ultra-slim, RedMere technology enables stronger signals to flow through your HDMI cable, making it possible to reach farther distances. It also allows for less copper wiring to be used, making the cables themselves thinner and lighter. You should note, however, that the RedMere chip that is built into your HDMI cable does pull some power from your signal source. While this is mostly negligible, it is still something you should be made aware of.
