Solution 1: The Device Connected must Output a Supported Resolution.

The TV supports the following resolutions:

  • 480i/p (640 x 480)
  • 720p (1280 x 720)
  • 1080i/p (1920 x 1080)
  • 2160p (3840/4096 x 2160)

Solution 2: Switch off the TV and the External Device.

  1. The TV and the external device should be turned off.
  2. Wait about 15 seconds after switching on the TV.
  3. The external device should be turned on.

In this test, the HDMI signal has been validated as having been sent between the two devices correctly.

Solution 3: Try to use an HDMI cable between 6 and 8 feet long.

An HDMI cable that is longer than 12 feet can sometimes cause the “Mode Not Supported” error message. Whenever a cable may be longer than 12 feet, make sure it is an ISF-rated cable.

You can set the resolution settings in your external device so that it will automatically detect the resolution that will produce the best display to the content being displayed. Alternatively, set it to the highest resolution your TV and the external device support.

Solution 5: If the resolution doesn’t work, try another HDMI device.

Usually, the TV works well with a second HDMI device at the same resolution, which indicates the signal being sent from the original device is what is causing the problem.

Solution 5: Make sure your TV is updated with the latest software.

How to Fix Samsung TV Not Recognizing HDMI Input?

Samsung is a trusted brand that you can trust. Even on these devices, there are still some issues to be found.

One of these is that the Samsung TV is not recognizing HDMI input. I hope these steps will help you troubleshoot if you are experiencing this issue too.

Why Samsung TV HDMI ports are not working?

If your Samsung TV HDMI ports not working for any of the following reasons:

  • The input of your TV is not connected to any device.
  • There is no power or the source is off.
  • There is a problem with the HDMI cable on both ends.
  • Your source does not match the resolution of your Samsung TV.
  • Your HDMI cable is damaged. 

One possibility is that your devices are not turning on correctly, and no HDMI signal is received with your Samsung TV.

The following tips should help you fix the “HDMI no signal” error on Samsung TV:

Solution 1: You need to reconnect the HDMI cable.

You may have connected the HDMI cable incorrectly or the cable came out loose. Make sure your TV isn’t connected to it. Likewise, if your Samsung TV doesn’t detect HDMI on your PC, do the same as above. 

  • Once you have reconnected the HDMI cable to the external device or PC securely, go ahead and proceed.
  • Then, you can connect the device to your TV.

Connect the cable to a different port in case that does not help.

Solution 2: Make sure your TV is set up correctly.

The first step after you connect a device to your Samsung TV is to set the TV’s source to the same port to which you connected the device.

So, if your console is connected to the HDMI 1 port, set the TV source to HDMI 1. When the TV does not show a signal, you could have confused the HDMI port.

Solution 3: Use another HDMI cable.

The cable you are using may not be compatible with the TV. You may also be unable to connect with a damaged HDMI cord.

Connect your Xbox, PlayStation, or Roku to the Samsung TV or any other device with a different HDMI cable.

Get a new cable if the cable seems to be the problem. Because it is braided so there is a minimum chance of damage, and it is suitable for streaming HD content without lagging, I recommend the iVanky high-speed cable.

Solution 4: Restart the external device.

If you power-cycle an external or a source input, you will refresh its parameters and enable it to restart again.

  • Remove the device from the outlet or power strip.
  • Let it sit for about 60 seconds.
  • Connect the source input back in.

Try again with the power on. Following all of the steps above, try powering your TV again. It will help if you reset the TV.

Solution 5: Check for software updates

The software for your inputs can be updated to resolve some HDMI handshake issues. If you are experiencing problems with your Samsung TV, then this step is imperative. In this situation, you should take the following steps:

  • Go to the Settings page.
  • Choose Support.
  • Click on Software Update.
  • Select the Update Now option.

Also, you can set the option to update automatically if you want it.

  • Go to the Settings page.
  • Choose Support.
  • Click on Software Update.
  • Highlight the Auto-Update feature.
  • Make sure the option is ON.

How to Change Resolution on Samsung TV

Several resolutions are supported on your Samsung TV, but the size and quality of the image depend on its source. You may have several options if you use HULU devices, depending on which playback device you’re using.

Your Samsung TV’s quality depends entirely on the quality of the device connected to your Blu-ray Player. Do you want to see the resolution of a specific source? Here’s how to do it:

  1. Press the Home button on your Samsung Remote.
  2. You can select “Source” using the left and right keys.
  3. Choose a specific source, such as “Comcast” or “Play Station”.
  4. In the right top corner of the screen, you will find the exact resolution. You may need to wait a few seconds to see it.

To find out the correct resolution, repeat the process for each source. Changing the picture size on your Samsung TV will change the resolution for each input source. This is often called the Aspect Ratio.
