Digitus HDMI Cable - 15m - Black

This cable supports resolutions up to 3840 x 2160 pixels (4K) at a refresh rate of 30Hz. It does not support higher refresh rates like 60Hz at 4K resolution.

Yes, the cable supports 3D content with a resolution of 1080p.

The signal amplifier boosts the HDMI signal, allowing for a clear and loss-free transmission of video and audio data over the 15-meter length, compensating for signal degradation that occurs with passive cables over long distances.

Yes, it supports the Ethernet Channel (HEC) feature, which allows network data to be transmitted over the HDMI connection.

The cable is designed for HDMI 1.4, but it is generally backward compatible with older HDMI versions, though features like 4K resolution and Ethernet Channel may not be supported by the older devices.

The amplifier is an internal component that works automatically. You will know it's functioning by the consistent and high-quality video and audio signal you receive over the long cable run, especially at resolutions like 4K/30Hz, without dropouts or degradation.

The connector contacts are plated with gold to ensure reliable signal transfer and resistance to corrosion.

Ensure both ends of the HDMI cable are securely connected to the source and display devices. Verify that the correct HDMI input is selected on the display. Try connecting the devices with a shorter, standard HDMI cable to rule out issues with the source or display. Reboot both the source and display devices.

Check for secure connections. Ensure the cable is not damaged or severely kinked. If possible, test with another HDMI cable. If the issue persists, it may indicate a problem with the source device, display, or the signal amplifier within the cable not functioning optimally under specific conditions.

Confirm that both your source device and display device support 4K resolution. Ensure the HDMI settings on your source device are configured for 4K output at 30Hz. Check that the cable is properly seated at both ends.

Ensure the cable is not subjected to physical stress or sharp bends. Check for potential electromagnetic interference from other devices and try to reposition the cable if possible. Test the cable in a different setup to isolate the problem.
