If your HDMI splitter isn't displaying an image on your connected TVs, here's how to troubleshoot, assuming your video source is connected to the splitter's input and the TVs are connected to the splitter's outputs, and the splitter's power indicator is on, and the TVs are set to the correct HDMI input channel:
First, check the basics:
- Power Supply: Make sure the splitter is receiving power and functioning correctly. Verify the power indicator light is illuminated.
- HDMI Cable Connections: Ensure all HDMI cables are securely connected. Check the connections between your video source, the splitter's input, and each TV.
- TV Input Selection: Confirm that each TV is set to the HDMI input corresponding to the port the splitter is connected to.
- Output Mode (for computers): If connecting a computer via HDMI, ensure the display output mode is set to either 'mirror' or 'extend'.
If the issue persists, consider these additional steps:
- Connection Stability: Make sure all connections are firm and not loose, which could interrupt the signal.
- Direct Connection Test: Try connecting your video source directly to a TV, bypassing the splitter, to determine if the problem lies with the splitter itself.
- HDMI Cable Quality: Use high-quality HDMI 2.0 standard cables, especially if you're aiming for 4Kx2K@60Hz signals. These cables are designed for optimal signal transmission.
If these steps don't resolve the issue, further investigation might be needed. Check the compatibility of your source device and TVs with your HDMI splitter. Also, confirm the TVs support the resolution being sent by the source device, and verify that your HDMI cables meet the HDMI 2.0 standard specifications.
