If you have a loss of audio or video signals when using HDMI® cable connections between your devices, consider the following tips:
Cable length - For 4K video performance. the length of the cable should be no more than 3 meters/10 feet. Longer cables may work, but the operation is not guaranteed.Note: In some cases, HDMI amplifiers can be used to increase performance on longer cable lengths.
Cable type - Do you have the right type of HDMI cable needed to transfer audio/video signals between your TV and other devices?There are four types of HDMI cables and they are backward compatible (HDMI standard):
- Ultra High-Speed (HDMI 2.1a) - Provides the best signal transfer capability. The cable has a bandwidth of 48Gbps, transfers resolutions up to 8K at 60Hz or 4K at 120Hz, and supports new features such as Enhanced Audio Return Channel (eARC) and Variable Refresh Rate (VRR).
- Verify that the HDMI cable transfers data:
- Change to another port on the TV and then the device.
- Connect the cable to another device and then to the TV.
- If the cable works, then the HDMI port on the device or TV may be defective.
- If there is still no signal transfer after switching ports and devices, then replace the HDMI cable.
