HDMI Not Working on Vizio TV

HDMI is the most popular connection for transmitting audio and video signal to a screen. It’s the standard connection for any smart device, including your Vizio TV. That’s why it can be so problematic when the HDMI connection simply stops working.

HDMI may not work on your Vizio TV because of a faulty or loose HDMI cable or a damaged HDMI input port. You may also be using the wrong HDMI port or an incompatible HDMI cable. You can fix this by trying a different HDMI cable and restarting your devices.

HDMI is one of the most popular ways to connect a computer or other device to a TV. This article will help you understand why HDMI is not working on your Vizio TV and how to fix it so you can enjoy your favorite movies and shows in high definition.

Why HDMI Is Not Working on Your Vizio TV

There are several reasons why the HDMI signal is not working on your Vizio TV, but most of the time the HDMI cable is the culprit. Let’s see exactly how that looks:

Faulty or Loose HDMI Cable

A loose or faulty HDMI cable will not work on your Vizio TV.

Make sure that the cord is securely plugged in. If it isn’t, push it in until it clicks into place. If there is no sound or picture on your TV, try another HDMI input to see if the problem persists.

Common symptoms of a faulty or loose HDMI cable include the following:

  • The TV does not recognize the HDMI input. 
  • The TV does not display any video or audio signal. 
  • You get a message on your TV screen saying “HDMI Input Not Supported” or “HDMI Not Connected.”

Damaged HDMI Input Port

It is not uncommon for HDMI input ports to become damaged over time, usually because of improper handling and rough treatment.

Damaged HDMI ports are not always easy to identify, but here are some warning signs:

  • TV will not turn on when the HDMI input port is connected
  • TV has no picture when the cable is connected
  • TV has sound, but no picture when the TV is turned on and the HDMI cable is connected
  • HDMI cable does not go in all the way into the TV port

Wrong HDMI Input Port

If the port you’re selecting is not the same as the port the HDMI is connected to, then your TV will show no picture.

For instance, if you plug your HDMI cable into input port ‘1’, make sure you select the same input on your Vizio TV remote control. Alternatively, you could connect the HDMI cable on the HDMI channel you’re currently on.

How To Fix HDMI Not Working on Vizio TV

Fortunately, the fixes for this issue are quite straightforward. But first, you should start by making sure that the problem isn’t being caused by the device you’re using. If your streaming stick, game console, or Blu-Ray player isn’t transmitting a signal in the first place, then none of these fixes will help you.

If your Fire Stick stopped working for no apparent reason, you can read my guide on how to fix it.

Restart Your Devices

If there’s a glitch not allowing your TV or your device to show a picture, your best bet is to restart them. Simply turn your Vizio TV off, wait about 30 seconds, and turn it back on. Do the same thing with the device you’re using to stream your content—streaming stick, Blu-Ray player, video game console, etc.

Clean the HDMI Port

You clean an HDMI input port by following these steps:

  1. Shut down the TV and disconnect all cables from the TV.
  2. Inspect the HDMI port for any damage, dirt or debris. Clean as needed with a damp cloth.
  3. Re-attach all cables to the TV and power it up to test if it works again.

If this doesn’t solve the issue, you may need to replace your TV’s HDMI input port.

Try a Different HDMI Cable

More often than not, the issue lies with the cable you’re using. Wether it was worn out over time, chewed on by a pet, or is simply a low-quality product, replacing it with a new cable should get you going.

You can buy a high-quality Vizio HDMI cable on Amazon. This cable supports up to 120 FPS and you can be sure it’s compatible with your Vizio TV.

Check the Display Settings on Your Computer

This fix only applies if you’re connecting your Vizio TV to a computer—usually a laptop.

You may not have the correct display settings selected. Most likely, your display settings are set to only show the laptop screen.

If you’re using Windows, you can check this by going into Settings, clicking on “Display,” and expanding the tab called “Multiple displays.” Maybe your laptop hasn’t detected the TV—in that case, click on the “Detect” button. If that’s not the problem, play around with the different settings.

If you’re using a Mac, you can reach the display settings by going into System Preferences and clicking on “Displays.”

Contact Customer Support

If none of the above manages to fix the HDMI signal on your Vizio TV, you might be looking at a hardware issue. It could be that you need to replace your TV backlights or it has a faulty T-con. Whatever the case, you’ll want to leave it to a professional.

If your Vizio TV is still under warranty, you can request a professional service here. If you’re no longer covered by warranty, then you’ll have to get a technician to look at your TV. There’s a chance that you’ll need to buy a new TV.

Final Thoughts

The HDMI signal on your Vizio TV may not be working for various reasons, but the most common problem is the HDMI cable.

The first thing to do if your Vizio TV’s HDMI isn’t working is check the cable. Make sure it’s properly plugged into the TV and the device you’re trying to connect.

If the connection isn’t the problem, try again with a different HDMI cable that you know is working fine. If the problem persists, then you may be looking at a hardware issue that needs professional assistance.
