Disconnecting the cords entirely from the power source and the computer is the best course of action for troubleshooting this. After letting everything rest for about a minute, reconnect it to the computer with an HDMI cable. To test the cord itself, try using a different HDMI cord.

Why Samsung Monitor Not Detecting HDMI

Turn off and unplug the monitor and computer to resolve the Samsung monitor not detecting the HDMI issue. Start your computer after the monitor has been powered on for 30 seconds.

If the problem continues, check that the appropriate input and display resolution settings are used and that all cables are correctly fastened and undamaged. You should attempt the following seven typical troubleshooting techniques.

How To Use A Computer’s HDMI Port?

Digital video and audio data are transmitted via HDMI cables between electrical devices like computers and high-definition Televisions (HDTV). The cable is connected to the HDMI connector on the back of these components, with a characteristic six-sided plug on each end.

Each plug has 19 steel connection pins that match the 19 holes in an HDMI port. The pins can transmit up to eight channels of digital audio and high-definition video.

How To Use A Computer’s HDMI Port
  • Connect one end of an HDMI cable to the HDMI Output port found on the back of the computer’s CPU or the edge of the laptop. The broader end of the plug needs to be rotated upward to fit the port.
  • Connect the power cord’s other end to an HDMI Input port on another audio/video device, such as an HDTV.
  • After turning on the device, watch for the “New Hardware Detected” message to display on the laptop or monitor.
  • On the computer’s control panel, double-click “Display Settings” to change the display output to the HDTV. By selecting the “Advanced” option from the display settings menu, the user can change the resolution from the computer to a resolution that the HDTV can handle. Consult the owner’s manual of your HDTV to learn its resolution.
  • Choose “Save Settings”
  • operate a Computer with an Internet connection to send Web material to the HDTV. To watch movies on the HDTV with digital sound, DVD or Blu-ray discs can be played back from the computer’s DVD or Blu-ray player.

Some of these cures require you to troubleshoot your system, while others involve you directly troubleshooting the display:

Step 1: Unplug And Reboot The Monitor And PC

Please turn off your computer and monitor and disconnect them before attempting anything else. Thirty seconds later, reconnect everything, switch on the computer first, then the display. I realize it.  Wasn’t that the reason you came here? Laugh at me.

Again, the order is crucial; switch on the computer LAST, then the monitor. Several people claim that after exhausting all other options, this straightforward technique was successful for them. Are you still experiencing the problem? Go to step 2 without worrying quite yet.

Step 2: Adjust The Monitor Input Setting

It’s crucial to check that the correct Input is selected on your monitor. You must first identify the input cable you are using to proceed. The Source/Input button on your monitor will either be in the center or on the right side. Either the bottom or the rear of the display will contain it. You may need to utilize the Menu button on some models before navigating to Input.

On your monitor, options appear once you push the Input and Menu buttons. Swipe through the input choices until “HDMI” pops up. A lot of the time, the problem is caused by just using HDMI 1 when you should be using HDMI 2 or vice versa. Toggling bettering both inputs is crucial for this reason.

Step 3: Inspect The Display Cables

Now that we’ve established that your monitor is configured to the proper Input let’s examine your display cable connections. Make sure that the connection is secure on both ends first. A loose wire may result in various problems, including screen flickering, no signal errors, and more.

Even a minor deterioration in the connection can result in an error. The tiny space you can see in the image below between my laptop’s HDMI port and the HDMI?

You guessed it, that was sufficient to result in the error. Next, ensure the cable is free of any problems or obstacles. Verify for any observable damage indications. Finally, experiment with an input cable other than your present HDMI cable.

HDMI, DisplayPort (DP), DVI, and VGA are the four cable types that Samsung monitors most frequently support. Remember to repeat step 1’s procedure and modify the display Input when you attempt a different cable. If switching to a different display cable resolves the problem, a defective display cable was probably to blame.

Step 4: Adjust The Monitor Resolution Settings

Your monitor can transmit various display resolutions back to your PC. Your computer’s graphic card might be set to a display resolution higher than your monitor currently supports. In some instances, this may even prevent your monitor from turning on. Restarting in Safe Mode will resolve this.

Your computer will automatically use a lower display resolution in Safe Mode than it would otherwise. This will give you a chance to choose a lower standard display resolution in the resolution settings of your computer. Do you need help with the resolution that your display can handle? You have two choices:

  • Locate the model number of your Samsung device on the back of your display and enter it into the Samsung user manual lookup.
  • Experiment and learn by making mistakes. Progressively raise your resolution. Between updates, allow around 30 seconds, then check whether an error notice appears.
  • Try using your monitor with a different device to check that your monitor is the problem.
  • You can use another laptop, desktop computer, video game console, etc., as this. If your monitor’s display functions, you can be sure that your computer or other hardware is to blame, not the monitor itself.
  • A few disclaimers first. You must open and handle your desktop or laptop computer to complete steps 6 and 7 below.
  • It is advisable to leave these procedures to your company’s IT assistance if the business owns your hardware.
  • Even if your computer or other hardware is privately held, you should take it to a nearby computer repair company.
  • If you decide to move further, ensure you have done your homework. To prevent damaging your computer with an electrostatic charge, you should, at the very least, understand how to ground yourself properly.

Step 5: Put Display Cable Into Graphic Card, Not Motherboard

  • An onboard graphics unit with associated connections is almost always found in desktop PCs.
  • Check that your display cable is linked directly to the graphic card and NOT the motherboard if this applies to you.
  • With a desktop PC, the process is frequently as easy as that.

Step 6: Remove, Reorder, And Reseat The RAM Sticks

  • Another possibility is that your RAM (Random Access Memory) sticks must be connected correctly.
  • Check that your computer is turned off and the power cord is unplugged from the socket before attempting to remedy this.
  • Then, remove each RAM stick from your computer by opening the case and properly grounding yourself.
  • Rearrange the sicks and put them back in the appropriate RAM seats.

Step 7: Reset CMOS/BIOS

  • CMOS stands for Complementary Metal Oxide Semiconductor.
  • The CMOS battery inside your laptop or computer powers the BIOS firmware. The “Basic Input/Output System,” or BIOS, controls the critical operations of your computer.
  • Resetting your BIOS restores it to its pre-issued settings, frequently resolving many problems.
  • Double-check that your computer is turned off, the power cord is unplugged, and you are correctly grounded.
  • After that, take the motherboard’s CMOS battery out. After that, press the power button to use up the last bit of juice.
  • Reinstall the CMOS battery in your PC after roughly a minute.
  • Restart your computer to test if your display is operational.
