4 Tips for Troubleshooting HDMI Splitters

Every AV installer knows how tricky it can get when you’re trying to set up multiple HDMI splitters to connect sophisticated high definition devices. Whether it’s assessing frequency range or setting up appropriate EDID settings, when you’re called upon to sort out any HDMI splitter-related AV distribution issues, there’s always an extensive checklist you need to abide by to resolve any complications.
While setting up HDMI splitters isn’t the most challenging installation to deal with, it’s inevitable that you’ll have connectivity issues that require extensive troubleshooting to help you find the root cause of the problem.
If you’re frequently running into signal issues or an HDMI splitter simply isn't working, here are four troubleshooting techniques to keep in mind to ensure optimal HDMI splitter performance.
1) Assess Why It’s Not Working
First things first, figuring out why your HDMI splitter isn’t working properly is the first step toward revitalizing it. Be sure to follow this quick checklist to sort out why your HDMI splitter isn’t performing properly:
- Ensure you’re using compatible HDMI cables
- Test signal power and try connecting other devices to signal source
- Check power source for HDMI splitter to see if it's providing sufficient power
- Review your HDMI splitter setup to see if it’s compatible with desired visual or audio resolution
Once you can officially assess why your HDMI splitter setup isn’t working, you can move forward with following appropriate troubleshooting protocol.
2) Unplug, Wait, Re-Plug
Sometimes the easiest way to troubleshoot your HDMI splitter is by simply unplugging and plugging it back into its power source. For example, leave your displays and video source powered on as you unplug the power cable and the HDMI cables from the HDMI splitter they’re plugged into.
Next, plug one of the displays back into the HDMI splitter, then wait for several seconds before you plug the power cable back into the HDMI splitter. You’ll be amazed at how often this works for troubleshooting your HDMI splitter setup and immediately getting your video and audio display back.
3) Reduce HDMI Cable Length
In many cases, longer HDMI cables could be what’s interfering with the performance and quality of your HDMI splitter setup. If this is the case, it might be worth investing in a HDMI extender or trying to rearrange the AV devices so they’re as close to the HDMI splitter and power source as possible. Reducing HDMI cable length often helps resolve any frequent connectivity issues.
4) Inspect Devices for Firmware Updates
Have you tried all of the above and are still having problems troubleshooting your HDMI splitter setup? Then it’s definitely worth inspecting all of your devices to see if any firmware updates are necessary. TVs, remote controls, video walls, audio hardware, etc. may have their own problem, so be sure to check all of these devices to see if they need a firmware update. Retest connectivity once you’ve successfully downloaded and installed any necessary updates.
