This error is very widespread and happens due to several different reasons. Either you may have the display connected to a wrong port or this might be a driver problem. We will go through the workarounds one by one starting with the easiest and work our way down. Note: Before you start with any of the solutions down below, navigate to the device manager (Windows + R and “devmgmt.msc”) and disable your GPU. After disabling it, enable it again. The problem was solved for the majority of the cases using this workaround.
Solution 1: Checking display connection
The first and foremost thing which you should check is the port where your display is connected. There are usually two ports where you can attach your display cable. Either you can connect the display to your Intel integrated graphics or to your NVIDIA graphics hardware. This is where most of the people get confused.
The port which is integrated with the motherboard is the display which is outputted by Intel HD graphics. The display which you see downwards is the display that is connected with your graphics hardware. Make sure that the connection to your monitor is plugged into the graphics port (also known as a discrete port as shown above) present in your system. Restart your computer after making the change and see if this fixes the error message under discussion.
Solution 2: Changing the adapter output
If you have correctly connected the display cable to your graphics card and the error message still persists, it is worth a shot trying either a converter or changing the form of output from the graphics hardware. You can either try using a VGA to HDMI Converter and use the HDMI port on your graphics card. Either this or you can change the form of output directly, for example, using a Display port instead of HDMI or VGA. Do some combinations on your own and see if this does the trick.
Solution 3: Checking NVIDIA Display Driver Service
NVIDIA has a service running on your computer which manages the display driver. It provides support to your operating system and is basically a middleware between your NVIDIA hardware and your operating system. There are cases where this service is stopped and because of this, the computer fails to detect your NVIDIA hardware.
Solution 4: Updating/rolling back Graphics drivers
We will try updating your NVIDIA hardware either manually or automatically. Furthermore, we will also use an application named as Display Driver Uninstaller (DDU). This will ensure that all remnants of the old display driver are removed so they don’t make problems for us in the future. Furthermore, if updating the drivers don’t work for you, you should consider rolling back the drivers to a previous build. There are many cases where the newer driver isn’t stable with your device and causes problems.
First, you should try updating the hardware automatically. Right-click on your hardware and select “Update driver”. Select the first option “Search automatically for updated driver software”. Choose the second option if you are updating manually and select “Browse for driver” and navigate to the location where you downloaded.
