In an ideal world, the HDMI cables you have will be exactly as long as you need them to be. Since that is not always possible to ensure, you might have two devices that rely on HDMI connectivity that are placed too far from each other. In such a situation, you can get a second cable and use an HDMI coupler to extend the connection. However, just like the cables themselves, the couplers should also be picked according to your needs. If you’re expecting to stream 4K content over the cables, the coupler you pick should also be capable of 4K passthrough. To help you pick the right one, we’ve curated some 4K HDMI couplers available on Amazon. Apart from promising specifications, these couplers also come with some useful features.
The AmazonBasics HDMI Coupler supports 4K at 60Hz, ensuring that your high-resolution videos stay smooth and detailed even after cable extension. It also allows a colour depth of 48-bit per pixel ensuring rich and vivid visuals for your favourite content. With a maximum bandwidth of 18Gbps, this coupler can handle more information without issues. The model also delivers a hassle-free experience with HDMI Ethernet connectivity. If you want 3D video playback over HDMI, this coupler also supports the same. With Audio Return Channel, you can use this coupler for connectivity with your home theatre setup for reliable usage.
The design of the J&D HDMI Coupler uses PVC material for maximum durability. The connector also uses gold-plated contacts to reduce the chances of corrosion for long-term usage.
