The majority of people have discovered that restarting the TV using the procedure outlined below resolves the issue of their Vizio TV not detecting an HDMI input. This is referred to as a hard restart.

  1. Turn off your device, followed by your Vizio TV.
  2. Disconnect all HDMI cables from the TV.
  3. Unplug your television from the wall outlet.
  4. For 30 seconds, press and hold the power button on the TV. This is typically found on the back of most Vizio TVs, but it may also be found on the side of the TV.
  5. Reconnect your HDMI cables to the TV.
  6. Reconnect the TV to the wall outlet and turn it on.

If the above does not work, you may need to try each of the troubleshooting methods listed below.


The first thing to look for is a faulty HDMI cable. These cables can become loose or damaged over time. Unfortunately, some cables can be defective from the start.

Unplug both ends of the cable and plug them back into the TV and device. You could even experiment with swapping the ends to see if one end fits better in your TV or device.

Check that you’ve pushed the cable all the way in. If this doesn’t work, try the same cable in another TV or a different HDMI cable in your Vizio TV to see if it’s a faulty or broken cable. Take note of which HDMI port you’re using.


The next thing to check is the input source on your television. This may appear to be a simple solution, but it has worked for some people.

When you inserted the HDMI cable, you probably noticed that the port was labeled ‘1’ or ‘2’. Check that you have selected the correct input source by pressing the ‘Input’ button on your remote.

You can cycle through each one to double-check if you’re unsure or if they’ve been labeled differently.



You could also try a different HDMI port. Individual ports can sometimes fail due to overuse. Just make sure to change the source of the input as well.

If none of the HDMI ports appear to be working, the problem could be with the TV’s computer chip, also known as the MotherBoard. If all of the ports are broken, this will need to be replaced.

Because this can be costly, try some of the other troubleshooting methods listed below or contact Vizio support to see if they agree.

They may even offer to replace the television as part of the warranty. In the meantime, if you need to use your device, you could always find an HDMI to AV converter.

This allows you to connect a newer device to the old TV input. Keep in mind that your picture quality will suffer as a result, so this is only a temporary fix.


You should also check your device’s display settings. This mostly applies to laptops because you can plug in a laptop and not see anything on the second screen.

The following methods will allow you to access your display settings on a Windows or Apple computer.

  • Start > Settings > System > Display in Windows 10
  • In older versions of Windows, go to Start > Control Panel > Display.
  • Apple Menu > System Preferences > Displays > Displays > Displays

You may need to fiddle with the settings here, but the most common problem is that the display is set to only the laptop.

For the audio/visual input to work, make sure you have chosen to mirror or extend your display onto the TV. You may also need to double-check the resolution, but I’ll explain why later.

The most common resolutions to experiment with are 19201080 (‘1080p’) or 1280720 (‘720p’). If this does not resolve the problem, try the troubleshooting methods listed above.


There is a reason why your Vizio TV is not reading, picking up, recognizing, or detecting the HDMI signal. These could be any of the issues listed below.

  • The HDMI cable is faulty/loose, or the HDMI port is faulty.
  • On the television, the incorrect input source is selected.
  • The display settings are either preventing or incompatible with the signal.
