FAQs

I've heard conflicting reports about HDMI Ethernet Channel (HEC). Is it worth it for home use?

The HDMI Ethernet Channel, which allows for data transfer over the HDMI cable, is a feature that sounds more impressive than it actually is in practice. While it has been a specification for years, adoption and implementation across most home devices is very limited. The bandwidth of existing HDMI cables with Ethernet support only goes up to 100 Mbps which is generally too low for modern home network use for streaming or gaming and it adds increased layer of complexity. The more likely scenario with HEC enabled cable is that it is simply wasted potential. In most home setups, a separate Ethernet cable for networking remains the more reliable and effective solution. Unless you have very specific needs and compatibility between your specific devices, a standard HDMI cable is usually sufficient. For example, if you're running a single streaming device connecting to your Wi-Fi router located nearby your TV, an additional Ethernet Cable would provide better connectivity while ensuring high performance.

How can I differentiate between genuine and counterfeit HDMI cables?

The market has counterfeit HDMI cables. To ensure you aren't getting a subpar product, look for several key identifiers. Start by checking for proper branding and packaging. Counterfeit cables often have blurry or incorrect logos and poorly printed boxes. Check the connector—genuine cables have precise molding with no evident defects; many counterfeit cables exhibit crude connector shaping or poorly implemented metal housing. Check for the certified logo and use official HDMI verification methods such as scanning a QR code or checking compliance through the official verification app (mentioned in the reference material). For example, the official HDMI organization runs a certification program for Ultra High Speed HDMI cables for which they offer easy-to-use verification methods via a smartphone app, thereby letting you distinguish genuine high-spec product from imitation cables. Ultimately, buying from reputable retailers is crucial to avoid counterfeit cables.

My new 8K TV doesn't seem to display at its full resolution and refresh rate. What could be the issue?

The resolution and refresh rate problems with 8K TVs mostly stem from an incompatibility between your equipment and the cable used. The first thing to verify is if the device itself and also the source device actually support outputting 8K signals. Even with high-end equipment, there often are various limitations. If the input and output both show support for 8K, next, check for your cable and connector types and verify that the cable specifications meet or exceed the resolution and refresh rate requirements. In this case, most likely an Ultra High Speed cable that supports 48Gbps is required. If you are using any adapters or switchboxes in the connection, then they are likely bottlenecks, so you need to avoid those factors. Lastly, after resolving all connection matters, refer to your television's settings to verify that the display is correctly configured to output the highest resolution and refresh rate to which your device allows, while also verifying that your source correctly supports the corresponding settings, too.
