FAQs
Is this cable active or passive?
This is an active HDMI cable, meaning it contains built-in circuitry to boost and equalize the HDMI signal, allowing for longer transmission distances without signal loss.
Do I need external power for this cable?
No, the active circuitry within the cable is powered by the HDMI port itself, so no external power adapter is required.
What is the maximum resolution and refresh rate supported?
The cable supports resolutions up to 4K (3840 x 2160 / 4096 x 2160) at 30Hz, and 1080p at up to 120Hz.
Can I run this cable inside my walls?
Yes, the cable is CL2 rated, making it safe for in-wall installations in residential and commercial environments.
Does this cable support 4K at 60Hz?
This cable is based on HDMI 1.4b standards and supports 4K resolution at 30Hz. For 4K at 60Hz, you would typically need an HDMI 2.0 or higher specification cable.
How do I know which end to plug into my TV and which into my source?
The cable is unidirectional. Connect the end labeled 'Source' to your HDMI output device (like a computer or media player) and the end labeled 'Display' to your HDMI input device (like a TV or monitor).
Does this cable support HDR (High Dynamic Range)?
This cable is HDMI 1.4b compliant and does not officially support HDR, which is a feature of later HDMI specifications (HDMI 2.0a and above).
Troubleshooting
No video or audio signal
Ensure the cable is connected in the correct direction ('Source' to source device, 'Display' to display device). Check that both HDMI ports on the connected devices are functional. Try connecting with a shorter, standard HDMI cable to confirm device functionality.
Intermittent signal loss or flickering
Verify that the connectors are fully inserted into the HDMI ports. Check for any physical damage to the cable. Ensure the connected devices support the resolution and refresh rate being transmitted. If installed in-wall, ensure the cable is not kinked or under excessive tension.
Reduced video quality or resolution limitations
Confirm that both the source device and the display support the desired resolution and refresh rate. Ensure the cable is not exceeding its specified bandwidth capabilities (e.g., trying to push 4K at 60Hz on a 1.4b cable is not supported).
