For a TV, the power reset or restart of the TV is a recommended troubleshooting step that can possibly resolve the HDMI signal issue
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):
- Standard (HDMI 1.0 to 1.2a) - Designed for basic consumer applications such as DVD players. The cable has a bandwidth of 5Gbps and supports up to 1080i (interlaced) or 720p (progressive) resolutions.
- High-Speed (HDMI 1.3 to 1.4a) - Designed to transmit 1080p, 4K at 30hz, and 3D signals. The cable has a bandwidth of 10.2Gbps.
- Premium High-Speed (HDMI 2.0 to 2.0b) - Designed to support HDR (High Dynamic Range) and 4K (60Hz) video signals and expanded color schemes.
- 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).
- Note: When using High-Speed or Ultra High-Speed cables, the video output of the device may need to be set properly. See your for details.
- 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.
