If you are looking for how to fix check signal cable Samsung monitor then you are at the right place.
If you follow all the steps that I ask and read all the instructions carefully, then you can solve this problem by yourself. So, let’s start!
How to Fix Check Signal Cable Samsung Monitor?
If your Samsung monitor is not displaying anything or displaying a blank screen, the first thing you should do is check the signal cable.
- Unplug the monitor from its power source.
- Check that all cables are connected correctly, then plug it back in and turn it on again to see if it works properly.
- If you still have an issue with your Samsung monitor, check for any loose cables or replace them if necessary before contacting a professional for further assistance.
What does Check Signal Cable Mean on Samsung Tv?
According to the research I did, checking Signal Cable is a message that appears on your Samsung TV, and it means there’s a problem with the cable.
The Check Signal Cable message can appear in different ways, depending on what type of cable you’re using.
If you’re using an HDMI cable or a component video cable, the message might read “Check Signal Cable”, “HDMI Not Supported”, or “Component Not Supported”.
If you’re using an optical audio cable, the message might read “Check Audio Cable”.
The solution to this issue is simple: unplug all cables from the TV, then plug them back in one at a time until you find which one is causing the problem.
Once you’ve identified that cable, try replacing it with a known working version for about ten minutes and see if that fixes your problem.
If not, contact Samsung customer support for further assistance!

Step 1: Check the Physical Connections
To fix your Check Signal Cable Samsung Monitor, first I advise you to check the physical connections.
If you have a cable connected to a monitor, it may be loose or unplugged. If you’re using an HDMI cable, make sure it is securely plugged into both ends of the connection.
If your monitor has more than one HDMI port, try plugging another device into another port to see if that works.
If it does not work with any other devices, then it’s possible that the HDMI port itself has been damaged or broken and needs to be replaced.
If your monitor has VGA and DVI ports, unplug them from their respective cables and then plug them back in again to make sure they are firmly attached and seated properly.
Step 2: Inspect the Signal Cable
To inspect the signal cable, first turn off your monitor and disconnect it from its power source. Next, plug in an external monitor to your computer’s video output port.
If you are using a laptop, connect an external monitor to your laptop’s VGA port using an HDMI/DVI to VGA adapter.
Now turn on the external monitor and check if it displays anything on screen. If it does not display anything, then you have a faulty signal cable that needs replacing.
If your external monitor displays an image but you cannot see anything on your Samsung monitor, then there is something wrong with the internal components of your Samsung monitor.
Step 3: Verify Monitor Input Source
To verify the input source of your Samsung monitor, follow these steps:
- Open System Preferences on your Mac and click Display.
- Click the Arrangement tab and then select 2 external displays from the drop-down menu.
- Choose either Mirror displays or Extend desktop to this display option and click Apply at the bottom right corner of your screen.
- Check if you can see your desktop on both monitors at this point, if so then your problem is solved!

Step 4: Test with a Different Cable
If your monitor is still not working, you may need to test it with a different cable. This will tell you whether or not the problem is with the cable itself and not your monitor.
First, turn off your monitor and unplug it from the wall outlet. Make sure all cables are disconnected from your computer as well as from your monitor.
Then, plug in the new cable into each end of your monitor and power on your computer.
If there is no change in how the screen displays then it’s likely that there’s something wrong with either the cable or your monitor itself.
If everything works normally then it’s likely that something is wrong with the old cable you were using before swapping out for a new one!
Step 5: Check Graphics Card and Computer Output
You can check the connection between your graphics card and computer output by using a digital multimeter.
Set the multimeter to ohms mode and then touch one lead of the multimeter to one of the monitor’s pins. Touch the other lead to ground (the black wire) on your computer output cable.
If you read less than 1 ohm, then the cable is most likely broken or damaged. If you read more than 1 ohm, then there is something wrong with your graphics card.
Step 6: Restart or Reboot Your System
If you’ve tried all the steps above and your Samsung monitor still isn’t working, it’s possible that the problem is with your system rather than the monitor itself. Here I have some things to try:
Restarting your system can fix many problems on computers. If your computer has been running for a long time and is getting slow, this may be the cause of your problem.
To restart your computer, press CTRL + ALT + DELETE (or hold down the power button for 10 seconds) to shut down Windows.
When you start up again, check to see if this fixes the issue with your Samsung monitor. You can also try resetting your BIOS settings by pressing F2 when you turn on your PC.
This will reset all settings back to default so it won’t interfere with any programs running on your computer.
Step 7: Update Graphics Drivers
The next step in fixing a Samsung monitor that has a check signal cable error is to update the graphics drivers.
To do so, you will need to go to the website of your graphic card manufacturer. For example, if you have an Nvidia graphics card, you will go to nvidia.com/Download/index.aspx.
There, you can download the latest driver for your operating system and model of computer.
Once you have downloaded the driver file on your computer, it will automatically install itself over top of any previous drivers you may have had on your computer before.
After it installs, reboot your computer and then restart your Samsung monitor (if it was still off when you first came here).

Step 8: Monitor and Display Settings
If you’re still having trouble after having tried all of the above solutions, try changing your monitor settings.
When you turn on your computer and it doesn’t display anything, it’s possible that the problem is with your monitor settings rather than with the cable itself.
To change these settings, perform the following steps:
- Press the Windows key + R to open a Run window.
- Type “Control Panel” into the box that appears and then press Enter or click OK.
- Select Hardware and Sound from the list at left and then click Display from the list on the right side of the Control Panel window.
- Click Advanced Settings in the left pane of this window if it’s not already selected; this will open up additional options in a multi-tabbed window on top of your screen.
- Click Troubleshoot under “Displays” in this new window; then select Reset Your Display Settings from the drop-down menu below it if that option is available to you (it may not be).
- This will reset all display settings back to default values so that they can be re-tweaked manually later on if needed.”
Step 9: Troubleshoot Hardware Issues
If you have tried all the above steps and still not getting a signal on your Samsung monitor, it might be a hardware issue.
To troubleshoot this, you need to verify that all cables are properly connected and that there is no physical damage to any components.
Check the cable connection:
I advise you to check if the cable is connected properly at both ends. Make sure the cable is not loose or damaged. If so, replace it with a new one.
Verify whether the cable is compatible with your monitor and computer system.
For example, HDMI cables are only compatible with HDMI-enabled devices such as laptops or desktop computers.
DVI cables are only compatible with DVI-enabled devices such as monitors or TVs. Ensure that you have connected your monitor to a compatible device using an appropriate cable type.
Step 10: Contact Samsung Support
If none of the above steps worked, you should contact Samsung support. You can do so by going to Samsung’s website and clicking on “Support.”
From there, click on “Contact Us” on the left-hand side of the page under “Support & Downloads.”
You will need to enter your email address and a brief message about what you’re trying to fix in order to get a response from Samsung.
