HDMI is the most common port we use to connect the CPU and the monitor in a computer. You can also connect your second monitor using an HDMI port. It is efficient in transferring signals compared to other cables.
But what happens if your monitor does not detect the HDMI connection? This page will explain all the possible ways to fix your monitor’s HDMI connection issues.
First, I want you to read this article completely; then only you can understand what are the possible ways you have and which one is best for you to apply.
Here are the two helpful guides for you.
Reinsert the HDMI Cable to Avoid a Loose Connection
Before anything else, why don’t you unplug the HDMI cable from the ports on the CPU and the monitor and reinsert it?
I’m suggesting this because sometimes loose cable connections occur. It is a casual problem in most cases of computer hardware.
Unplug the HDMI cable at both ends and reinsert it to fix the monitor detection issue.
If this is not the case for you, then go to the next one.
Make Sure HDMI Mode is Selected on Your Monitor
Today’s monitors have more connecting features, and devices have multiple connecting ports, which is one of the good features.
So, to detect the signals from the HDMI cable, you must select the HDMI path on your monitor. You can select the ‘auto-select’ option if you want, but sometimes, the auto-select option may or may not exist. So choose HDMI mode after connecting your cable.
These options are available in monitor settings but not in Windows settings. You can go to the monitor settings with the help of the given buttons. These monitor buttons and settings are different from one PC to another.

Replace the Faulty HDMI Cable
Is the HDMI cable working properly? If it isn’t, then there is nothing you could do except replace it.
If you are not sure whether the HDMI cable is working properly, then you can replace the HDMI cable with another one and check.
After doing this, if your monitor is detectable and getting signals from the CPU, then you can confirm that a faulty HDMI cable causes a monitor detection issue on your computer.
Forget the HDMI Port and Use Another One on the CPU
You can’t compromise with the HDMI port if you have DisplayPort or any other one to connect your CPU to the monitor.
For example, let’s take the VGA port. If VGA is the common port for both your CPU and monitor, then you don’t need to think for a second about connecting them with the VGA cable.
HDMI alternatives are DVI, VGA, DisplayPort, etc. You can choose any one of them.
If your CPU has one port (Display) and your monitor has another one (VGA), then you can also connect them with the help of a Display to VGA converter.

Use Another Port on Your Monitor
Just like another port on the CPU, you’ll have another port on the monitor. So, you can use this as an alternative for an HDMI port to connect.
If you need, you can use the converters from one port to another port. If your monitor has HDMI detection, then use this method.
Clean the Dust To Avoid Signal Errors
Dust is a bad thing when it comes to computer hardware, particularly when plugging or connecting.
In the process of fixing a monitor not detecting HDMI, you should clean the dust in 3 areas.
- HDMI port on the CPU
- Monitor’s HDMI port and
- HDMI cable at both ends
I want you to have a professional computer cleaning kit like this. It helps to save your time in cleaning your PC without any damage to the computer parts.
Clean all of the pins carefully without any dust accumulation or unwanted pin damage.
After cleaning, re-connect the HDMI port at both ends to the CPU and the monitor and check whether the CPU is sending signals to the monitor through the HDMI cable or not.
If not, then dust is not the problem. Go to the other one.
Restart Your PC to Fix Any Signal Errors
Finally, I want you to restart your computer. Because sometimes minor signal errors might occur. To avoid them you need to restart your PC.
However, it is advisable to restart your PC at every instant like after cleaning the dust, after reconnecting the HDMI cable, after changing your monitor’s working mode, etc.
A restart helps the PC to read and respond to the changes you made.
Also, give your PC some time for driver installation. The drivers are like lubricants to a computer. So, don’t be in a hurry until you find the result. If you don’t know how to upgrade your PC drivers, just follow this guide.
Conclusion
Let me guess now you have an idea where the problem occurred and have fixed the issue that your monitor is not detecting HDMI cable or connection.
Don’t depend on only one port (HDMI). If situations like this occur, you are free to use Displayport or any other port. In terms of performance, both DisplayPort and HDMI are the same. So, there is no need to worry about choosing any one of them.
Remember, if you are facing this problem connecting your dual monitor, then check the motherboard’s manual to find out whether it is compatible with a dual monitor connection or not. If your motherboard can’t support dual monitors, then no cable helps in connection and usage.
