Change The monitor’s input settings:

If your Samsung monitor does not recognize HDMI, double-check that the Input setting is right. To begin, determine the type of input cord you’re using.

Your monitor’s Source/Input button will be in the center or on the right side. It’ll be on the backside or at the bottom of the display.

Some Samsung monitor variants need you to press the Menu button first and then choose Input.

Your monitor will display options once you push the Input and/or Menu buttons. Toggle through the input options until “HDMI” appears.

Examine The Cables That Connect The Monitors:

Let’s examine your display cable connections now that we’ve confirmed your monitor is configured to the right Input. First and foremost, ensure that both sides of the connection are secure.

One of the most typical causes of a Samsung monitor not recognizing HDMI error is a loose cable. Even if the connection is marginally damaged, an error might occur.

After that, inspect the cable for any problems or obstructions. Look for any apparent evidence of damage. Finally, try a different input cable than the HDMI one you’re using right now.

HDMI, Dp, and VGA are the most popular cables supported by Samsung displays. Determine the type of alternative cable you have.

If you’re trying out a new cable, make sure to repeat step 1 and set the display Input appropriately.

If switching to a different display cable fixes the problem, the problem was most likely caused by a malfunctioning display cable.

Change The Resolution Of Your Monitor:

Your Samsung monitor can send a variety of display resolutions back to your computer.

It’s conceivable that your computer’s graphic card is set to a display resolution that your monitor can’t support right now.

If this is the case, the Samsung monitor not detecting the HDMI message you’re getting might be the result. 

In Safe Mode, your computer will use a lower screen resolution than it would otherwise. It will allow you to go into the resolution settings on your computer and pick a lower conventional display resolution.

Do you know what resolution a Samsung monitor could handle? You can choose between two options:

  • Look for your Samsung model reference number of the monitor in the Samsung user manual search engine.
  • Experiment with some trial-and-error. Increase your resolution in small increments. Wait thirty seconds for each update to check whether the notice “Samsung monitor not recognizing HDMI” appears.

It’s conceivable that your Samsung display is reporting no signal because your RAM sticks aren’t properly connected.

Ensure your computer is switched off and the power supply is unplugged from the socket to fix the problem.

After that, ground yourself properly, open your PC, and completely remove each of your RAM sticks. Finally, rearrange the sacks and re-insert them into their RAM seats.

The BIOS firmware is powered by the CMOS battery in your laptop or computer. BIOS stands for “Basic Input/output System,” and it’s in charge of all of your computer’s important functions.

Resetting your BIOS restores your computer’s previous settings and can often fix a wide range of issues.

Make sure your computer is switched off, the power cord is unplugged, and you’ve rooted correctly once again.

Disconnect the CMOS batteries from the board after that. Then press and holding button to drain any leftover power.

After about a minute, replace the CMOS battery in your computer. Finally, restart your computer and verify that your display is operational.
