1. The power supply of the graphics card is not connected properly and the graphics card does not start. The contact between the graphics card and the motherboard is poor and cannot make normal contact. The graphics card is damaged or defective. The motherboard does not support the current graphics card and cannot be used.
2. If there is one, unplug it first, then turn on the computer and connect the core display. It should be fine. This is the simplest. You can also set the BIOS setting for core graphics output or independent graphics output without unplugging the independent graphics card. Please refer to the BIOS operation manual for details.
3. It is caused by insufficient power supply. b450mrx580 is an independent graphics card used on desktop platforms. When using it, the problem of not lighting up is caused by insufficient power supply. You need to check the power supply and try again.
Make sure the monitor is connected correctly and is plugged into the VGA port of the independent graphics card. If it is plugged into the integrated graphics card, there will be no display. If there is still no display after the connection is correct, it is recommended to plug it into the integrated display to determine whether your independent display is installed properly.
The host is running normally, are you sure? If it is connected to another normal monitor, it will display normally, then the monitor is broken. Generally, home computers and LCD monitors will not suddenly black out. No display, first find the memory problem. Most motherboards will make a popping sound. A few motherboards do not have speakers installed on the motherboard. So silent.
The graphics card and the motherboard are not compatible, or there is a problem with the graphics card. You can try upgrading the motherboard bios. If it still doesn't work, the only option is to change the graphics card.
There is another option you can try: As shown in the figure, Init Display First (boot display selection) This option allows you to choose to prioritize the output from the built-in display function, PCI graphics card or PCI Express graphics card when the system boots. PCI systems will output from the PCI graphics card.
If you install an independent graphics card, you can choose to connect the output cable directly to the independent graphics card. If you need to output multiple screens, you can also choose an independent graphics card to achieve multi-screen output.
There is dust or foreign objects in the independent graphics slot, causing the motherboard to be unable to recognize the independent graphics card. At this time, you need to clean up the dust or foreign objects and then replace the graphics card. Plug it in. There is a problem with the graphics card itself. At this time, the only option is to take the graphics card for repair or replace the graphics card.
Driver issues The discrete graphics card is not installed correctly or the driver is damaged, which may cause it to not work properly. The correct driver for your graphics card needs to be downloaded or reinstalled to ensure the card is functioning properly.
The driver is not compatible. Or you changed the operating system. If it is the former, download the driver wizard and select the compatibility mode driver to solve the problem.
The independent graphics card cannot be detected. The steps are as follows: Right-click My Computer, Properties, and click Control Panel Home Page. Find the uninstaller. Find the NVIDIA graphics driver uninstaller in the list. Wait for the uninstallation to complete, and check the driver that needs to be updated in Master Lu software. If the graphics card driver is found, it will be installed automatically.
First, click on the “This PC” icon on the desktop. Then in this interface, right-click the "Manage" option. Then in this interface, click on the "Device Manager" option. Then in this interface, select the "Discrete Graphics Card" option in "Display Adapter".
The computer is turned on and the motherboard is powered on. The monitor is powered on (the power indicator light is on) but there is no signal or the screen displays "no sighal". This is usually because the memory module is loose or Poor contact due to oxidation, or poor contact of the display data cable, or damage to the memory, graphics card, display or data cable.
The monitor shows no signal, indicating that the monitor is powered on normally. If the host is running normally, it is recommended to cut off the power supply of the monitor and the host, then remove the connection cable between the monitor and the host and reconnect it. Pay attention to whether the indicators of the monitor connection cable are damaged.
Cause: There may be a problem with the HDMI cable. Check whether the TV’s signal source is HDMI. Can the TV be recognized normally in the control panel of the NVIDIA graphics card driver? If not, the TV can be forced to be recognized. Please note that HDMI is best not to be hot-swapped and plugged in when the device is powered off.
You can try re-plugging the graphics card and making sure they are firmly connected. Check your computer's BIOS settings to make sure integrated graphics or discrete graphics are enabled. Finally, if all of the above steps fail, there may be a hardware failure with your graphics card or motherboard. At this time, it is recommended to contact after-sales service or professionals for repair.

Unplug it again; it may be that the interface between the independent graphics card and the motherboard is loose.
