1- Unplug And Reboot The Monitor And PC

If you have a problem with your Samsung monitor failing to detect HDMI, the first step is to unplug and reboot it. 

To do this disconnect your Samsung monitor and PC from their power sources. 

After that, reconnect them securely while turning on the monitor before turning on the PC. 

Check if the issue regarding detecting HDMI has been resolved once everything is up and running again. 

If not, you may need to connect all cables again or try using a different connection type like DVI or VGA. 

If this does not solve the problem, it might be due to outdated drivers or faulty hardware.

2- Loose Cables Connection

Any loose cable connections can lead to a Samsung monitor not detecting HDMI. 

For smooth connectivity of a Samsung monitor with HDMIs, the cables must be connected properly and securely at both ends. 

If partially disconnected or loose in the devices or the monitor, it may lead to detection issues on the Samsung monitors. 

Before trying any other solution, you must ensure that you have unplugged and plugged back the cables at both ends for proper connection.

Even if that doesn’t work, using another cable might help, or try different ports.

If all else fails, reinstalling drivers from Sammy will prove helpful for your device and monitor.

3- Damaged HDMI Cable

There are a few other possible causes for the problem that Samsung monitors do not detect an HDMI cable. 

One of the most likely reasons is that your HDMI cable may be damaged, which can cause poor connectivity or distorted signals. 

If you inspect the HDMI cable for any visible signs of damage, you need to fix or replace it with a new one if necessary. 

There may also be an issue with your Samsung monitor itself.

In this case, you should reset or update the monitor’s firmware to get things working properly again.

4- Damaged HDMI Port

If the port or cable is damaged, Samsung monitors can suffer from an issue where they fail to detect HDMI connections. 

If your Samsung monitor is not detecting an HDMI connection, this could be because of a faulty or damaged HDMI port or cable. 

If your Samsung monitor only has one HDMI port, frequent use might cause it to wear and tear. 

Another possibility for why your Samsung monitor may not present pictures when you join devices using an HDMI link is the lack of compatibility between the two devices and cables. 

We recommend that you ensure that any HDMI cable you employ with your Samsung monitors is also compatible with the device you wish to connect. 

5- Adjust The Monitor Input Setting

When a Samsung monitor fails to detect an HDMI connection, the issue is probably caused by the incorrect input setting on the monitor.

Press the “Menu” button on your Samsung monitor’s remote control or physical buttons to adjust this setting. 

Navigate through the settings menu to find and select “Input,” then choose “HDMI” for the input source. 

If this does not work, check if your Samsung monitor is set up correctly and securely connected to your device. 

6- Update Outdated Driver

To solve the issue of not detecting an HDMI connection on your Samsung monitor, you must update the outdated driver on your monitor. 

Depending on which Samsung monitor model you are using, the process for updating the driver may vary. 

You should visit Samsung’s website and search for your device to download the latest driver update package. 

After downloading it, run it to install a brand new Samsung Monitor Driver that will ensure all necessary components for detecting an HDMI connection are up-to-date. 

In some cases, restarting your computer after installation may also be required for changes to take effect and for your Samsung monitor to detect an HDMI connection properly again. 

Once you have updated the driver on your monitor, try connecting your HDMI device to it again. Contact technical support if it still does not detect the correct signal input.

7- Problem With The Graphic Card

If you have tried all the given steps above this point and you are still facing the problem with your Samsung monitor, the problem may lie in your graphics card driver. 

Ensure it’s up-to-date and compatible with your Samsung monitor to detect the HDMI connection properly. 

If updating the driver doesn’t help, you may need to replace the graphics card for optimal performance of your Samsung monitor. 

Samsung monitors are designed to work with other devices, but sometimes the connection isn’t detected due to outdated or incompatible graphics card drivers. 

Updating or replacing the driver should solve the problem and get your Samsung monitor working properly again.

8- Corrupted BIOS Setting

When certain bits of the BIOS become corrupted or damaged due to various incidents can cause Samsung monitors not detecting HDMI connections. 

The BIOS (basic input/output system) is firmware embedded in the motherboard that helps control and manage hardware components. 

To resolve this issue, the BIOS settings must be reset by booting into safe mode and restoring the original factory settings. 

Once the backup is complete, restart the computer and press the appropriate key (usually F2, F10, DEL, or ESC) to enter the BIOS setup. 

Then navigate to the “Advanced” menu and look for a “Reset BIOS Settings” option. Finally, select this option and save your changes before restarting the system. 

After the reset is complete, Samsung monitors should detect HDMI connections again.


In conclusion, if your Samsung monitor is not detecting HDMI, you can troubleshoot your problem by following these steps:

  1. Unplug And Reboot The Monitor And PC
  2. Loose Cables Connection
  3. Damaged HDMI Cable
  4. Damaged HDMI Port
  5. Adjust The Monitor Input Setting
  6. Update Outdated Driver
  7. Problem with the graphic card
  8. Corrupted BIOS Setting

If you have tried all these steps and have not found any solution, it is best to contact Samsung customer support. 

They will give you the solution to troubleshoot your monitor sound problem because they have a qualified team. 

If your monitor has a serious problem, it is best to buy a new monitor instead of wasting your money on an old Samsung monitor.


Why is my monitor not displaying through HDMI?

One cause of a monitor that is not displaying through HDMI could be an HDMI port, cable, or connection issue. 

Restarting the PC may help resolve the issue. 

To restart your PC:

  1. Hold the power button until it shuts off completely.
  2. After a few seconds, press the power button again to start your PC.

If the monitor continues to not display when connected through HDMI, try other troubleshooting steps, such as changing the HDMI cable or port.

Why is my monitor showing no signal?

The “No Signal” message indicates that your monitor is not receiving any signal from the PC. 

A loose connection between your monitor and the PC, such as a loose cable or port, can cause this issue. 

Additionally, video card drivers are often responsible for no signal issues as they must be up-to-date for your computer and monitor to communicate properly. 

A faulty graphics card or hardware failure can also cause this issue. 

Try troubleshooting by checking all connections from the back of your CPU to ensure everything is properly connected.

How do I get my broken HDMI port to work?

It is important to follow a proper procedure when your HDMI port is broken, and you want to fix it. 

In the first step, you must check that all your cables are properly connected and secure. 

If this doesn’t solve the issue, you must consult a professional who can further diagnose the problem and suggest repair or replacement solutions. 

Some manufacturers may have service centers with technicians who can help identify and resolve any issues with your device’s HDMI ports.

Is a broken HDMI port fixable?

Yes, a broken HDMI port can be fixed. 

Many repair and replacement options are available depending on the severity of the damage. 

For example, if the port is damaged but still working properly, it might be possible to repair the existing port by replacing cables and/or soldering wires. 

On the other hand, if the entire HDMI 2 port is completely broken, replacing it entirely may be necessary.

What is the alternative for the HDMI port?

When connecting a computer such as a laptop, desktop machine, monitor, or projector to a display, VGA and DVI ports are the most common alternatives to HDMI. 

VGA stands for Video Graphics Array and is an analog signal that transmits video information using separate channels. 

DVI stands for Digital Visual Interface and provides a digital communication channel to transmit high-resolution images more efficiently than VGA. 

Many newer devices use DVI connectors instead of VGA ones, including many laptops and gaming consoles.

Can a bad HDMI cable damage the monitor?

No, a bad HDMI cable cannot damage the monitor. 

The cable is merely the connection between two devices and does not have the capability of directly harming the monitor. 

The cable carries a signal, which an improperly constructed or damaged cable can corrupt, but this cannot harm the monitor itself. 

The monitor may not properly interpret the signal, resulting in an incorrect or no picture, but this does not damage the device.

Should my monitor be HDMI or DisplayPort?

When considering whether HDMI or DisplayPort is the right connection type for your monitor, HDMI is technically the higher-performing option. 

HDMI offers a much higher resolution than DisplayPort and supports higher refresh rates up to 120Hz. 

HDMI also supports a wide range of audio formats, providing more flexibility for gaming and multimedia. 

HDMI also has the advantage of being more widely available, with HDMI ports found on many consumer electronics devices.
