If your NVIDIA graphics card is not detecting HDMI monitors, here are some troubleshooting suggestions you can follow to fix the issue. Even if you have already gone through some basic steps to make it work again, you should follow all the below-mentioned solutions again.
Most NVIDIA graphics cards have either an HDMI+DVI-D, HDMI+HDMI, or HDMI+VGA port combination. Whether you use an older or modern graphics card, there is a high chance it has an HDMI port. However, this port may not work if you have been using it for a long time for various reasons. In such situations, you could follow this guide.

1] Verify HDMI cable and port
It is probably the first thing you need to check when your graphics card is not detecting the HDMI device. Whether it is NVIDIA or any other company, you must start the troubleshooting process with this step. If your cable is faulty, you will waste your time by following other methods first.
You can verify that by using it with another computer. Maybe you can take it to the local computer store, and ask for professional help. Not only the cable, but it is also mandatory to check whether the HDMI port on your monitor is fully functional. The process is the same. You need to connect it to another computer with an HDMI cable.
Pro Tip: Many people use a converter in order to use the HDMI port. For example, if you have a VGA to DVI-D cable and a free HDMI port, you can simply use a DVI-D to HDMI convert to make use of the free port. However, that may create problems. If the converter doesn’t work correctly or support your cable, you won’t receive any signal on your monitor.
2] Choose HDMI option manually
Most monitors allow users to choose among various sources, including HDMI and DVI-D. By default, most of them select the options as you connect the respective cable. However, if your monitor doesn’t do that automatically, and it is set to DVI-D or VGA, you won’t be able to use HDMI. That is why it is recommended to manually select the HDMI option.
Even if your computer is not getting any signal, you can use the physical buttons to choose the option.
These are the two things you can do without getting any signal through the HDMI cable. However, if you have another monitor or cable to connect to a monitor via DVI-D or VGA port, you can follow the rest of the solutions.
3] Change screen resolution
If you have an old monitor, you cannot force it to use a different resolution than the default. For example, it supports 1366 x 768 pixels, and you selected 1920 x 1080 pixels. In such situations, some older monitors might not be able to comply with this setting. That is why it is recommended to use the original screen resolution.
4] Change Scaling
It is another setting that might cause the same problem on your computer. Old monitors do not always support high or lower scaling due to various restrictions. In such situations, you may end up getting nothing on your screen. That is why it is recommended to use the default scaling setting.
The best thing is that you can change scaling using NVIDIA Control Panel. For that, open the NVIDIA Control Panel and go to Display > Adjust desktop size and position section.
From here, choose the Aspect ratio option from under the Select a scaling mode.
5] Install or update driver
If you have Windows 11 or Windows 10, you might not need to install the graphics driver in order to use a dual monitor setup. However, the driver makes things smoother and lets you control various aspects of the graphics card. That is why installing the graphics driver is recommended.
However, if you have already installed it earlier, you may want to update the graphics driver.
That’s all! Hope this guide helped.
