You can either try using a VGA to HDMI Converter and use the HDMI port on your graphics card. 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. Restart your computer after making the change and see if this fixes the error message under discussion. 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.
The display which you see downwards is the display that is connected with your graphics hardware. The port which is integrated with the motherboard is the display which is outputted by Intel HD graphics. This is where most of the people get confused. Either you can connect the display to your Intel integrated graphics or to your NVIDIA graphics hardware. There are usually two ports where you can attach your display cable. The first and foremost thing which you should check is the port where your display is connected. The problem was solved for the majority of the cases using this workaround. 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.
