FAQs
What does 'Active Repeater' mean for this cable?
An active repeater cable has built-in electronics to regenerate and strengthen the HDMI signal. This is crucial for maintaining signal integrity over longer distances like 20 meters, ensuring a stable picture and sound.
Can I use this cable for 4K video?
Yes, this cable supports HDMI 1.4 and is tested to support resolutions up to 4K2K (3840 x 2160), providing capability for high-resolution video.
Is this cable compatible with 3D TVs?
Yes, the cable supports 3D over HDMI, allowing you to enjoy 3D content if your source device and display are 3D-capable.
How do I know if I need an active HDMI cable?
Active HDMI cables are generally recommended for runs longer than 5-10 meters, especially when transmitting high resolutions like 1080p or 4K. If you experience signal dropouts, flickering, or a lack of signal with a standard passive cable of similar length, an active cable is likely needed.
Does the gold plating affect performance?
The gold plating on the connectors primarily enhances corrosion resistance and ensures a more durable, reliable contact over time. It helps maintain a clean signal path.
What is the Audio Return Channel (ARC) feature?
ARC allows your TV to send audio back down the HDMI cable to an AV receiver or soundbar. This means you can use a single cable for both video to the TV and audio to your sound system, simplifying connections.
Do I need to install any drivers for this cable?
No, this is a plug-and-play device. HDMI cables, including active ones, do not require driver installation. They are automatically recognized by connected devices.
Troubleshooting
No picture or intermittent signal
Ensure both ends are securely plugged in. Try connecting to different HDMI ports on your devices. If using with very old devices, ensure the cable's active features are compatible or try a shorter, passive cable to rule out cable issues.
Video resolution is lower than expected (e.g., 1080p instead of 4K)
Verify that both your source device and display device support the desired resolution (e.g., 4K). Confirm that the cable is connected correctly and that no other components in the chain are limiting the resolution.
Audio is not working
Check the audio output settings on your source device. Ensure that HDMI audio is enabled and selected. Verify that ARC is enabled in the settings of both your TV and AV receiver/soundbar if using that feature.
Device connected via HDMI Ethernet channel not accessing network
Confirm that both devices connected by the HDMI cable support the HDMI Ethernet Channel feature and that it is enabled in their respective settings.
Pros and Cons
Pros
- Provides excellent signal integrity over a long 20-meter run thanks to the active booster.
- Supports advanced features like 3D, 4K2K resolutions, and ARC.
- Gold-plated connectors ensure a robust and reliable connection.
- Built-in Ethernet channel simplifies networking between compatible devices.
Cons
- Being an active cable, it requires proper orientation or connection to function correctly.
- The active circuitry may consume a small amount of power from the connected HDMI port.
- May be overkill for very short-distance connections where a passive cable suffices.
Setup, Compatibility & Care
Setup: Simply connect the Male Type A HDMI connectors on both ends of the cable to the corresponding HDMI ports on your source device (e.g., laptop, media player) and display device (e.g., TV, projector). Ensure the connection is firm.
Compatibility: This cable is compatible with any device featuring an HDMI Type A port and supports HDMI 1.4 standards. This includes most modern HDTVs, projectors, computers, gaming consoles, and AV receivers. It is backward compatible with older HDMI versions, though it will only support features of the lowest common version between connected devices.
Care: Keep the cable and its connectors clean and free from dust. Avoid sharp bends or kinks, especially near the connectors, as this can damage the internal wiring or active components. Store the cable loosely coiled when not in use.
