HDMI ports are crucial for connecting external devices to your TV, which is why it is important that you know how to resolve HDMI input recognition issues. Thankfully, there are several troubleshooting steps you can take to address the issue and get your Samsung TV to recognize the HDMI input again.

I’ll share the possible causes and solutions for when your Samsung TV fails to recognize an HDMI input. You can try multiple troubleshooting methods to find the fix that works for you.

Why is My Samsung TV Not Recognizing The HDMI Input?

There are several reasons why a Samsung TV may not be able to recognize HDMI inputs. Some of the most common reasons are:

  • Bad cables
  • Issues with the input source
  • Firmware that is outdated
  • Insufficient power supply

How To Fix Samsung Not Recognizing HDMI Input

Fortunately, there are various steps you can take to address this issue and potentially resolve it.

To begin troubleshooting, follow these steps:

  1. Start by disconnecting one end of the HDMI cable from the TV and the other end from the external device.
  2. Next, reconnect the HDMI cable to the external device
  3. Note: If you own a Samsung TV model from 2016 or earlier, you will need to manually select the appropriate source on the TV.

1. Check The Condition of Your HDMI Cable

When connecting your PC to your Samsung TV using an HDMI cable, you may encounter a situation where the TV does not recognize the input. This can happen if the HDMI cable itself is faulty.

To address this issue, you can test the faulty HDMI port by plugging in other devices. If these devices work with the port, then the problem may lie with your external device.

Also, before you assume that the cable is at fault, try connecting your Samsung TV to another HDMI input. If your device works properly with the other HDMI input, it indicates that the cable you initially used is indeed faulty.

If none of the devices work with the faulty HDMI port, it suggests that the issue is either with the HDMI cable itself or with your Samsung TV.

2. Update Your Samsung TV

If you have completed all the recommended tasks but your Samsung TV still fails to recognize the external device, there may be issues with your device itself, particularly with its software. Outdated software could potentially cause this problem. To address this, you should check if there is a software update available for your device and proceed with the following steps to update it:

Step 1: Ensure that your device is connected to a strong Wi-Fi network. A stable internet connection is necessary for updating your Samsung TV.
