The installation of the independent display driver is completed, and the display is not lit when plu

After installation, restart and try,After installation, you need to restart to let the system recognize the display interface,If you still can't take it, you have to turn off the integrated one in the BIOS。

If the data cable is broken, you can replace it (if it is the same as the socket display, then it can be excluded).

If the installation of the GPU driver is incomplete or incorrect, restart it and try it. Or try to use software such as Master Lu Driver Elf to detect updates.

If none of the above is true, then the graphics card may not be compatible with the motherboard or broken.

Confirm whether it is indeed the independent display that does not light up, if so, it is possible that the independent display is not plugged in, open the case, remove the graphics card, and then wipe the gold finger, reinstall it and try again.

You need to set it up in the BIOS, turn off the integrated display, and use the independent graphics card.

Because the BIOS uses the integrated display by default, the integrated display will be bright.

In this case, it may be because of the mismatch of some corresponding devices, if it does not match, he will not be able to identify some information as the corresponding in the settings, and there will be no way to view the corresponding some and display.

After the installation of the discrete graphics card is completed, you need to restart the computer to start the discrete graphics card normally and ensure the picture quality.

The reasons are as follows: 1. If there is generally no compatibility between the motherboard and the graphics card, as long as the interface is the same, it can be lit.

2. Check whether the signal cable of the display is connected to the output interface of the graphics card, and if it is connected correctly, replace a cable with a little bit of ***.

3. It may also be caused by poor contact between the graphics card and the motherboard, and the gold finger part should be completely in contact with the PCI slot of the motherboard when the graphics card is reinserted and unplugged.

4. The display signal source should be switched correctly, and some monitors have an auto icon in the lower right corner, you click it.

5. If the graphics card has an auxiliary power supply cable, it is recommended to use some brand power supplies with good quality and large power consumption.

If the above methods are checked and still can't be lit, it is recommended to send the graphics card for after-sales testing.

This is a result of the BIOS not being able to recognize the discrete graphics card.

If short pressing the power switch is invalid, press and hold the switch until the power indicator turns off or directly unplug the power cord, turn off the power and turn on the chassis, plug the memory module back in, and wipe the gold finger together with the direction of the eraser.

If possible, it can be installed in different memory slots. After installation, you must touch the wall with your hands to release your static electricity or wear anti-static gloves before starting the operation.

Slap or kick the case on the left and right sides of the case without an interface on the back**, be careful not to use too much force, and of course not to be weak.

BIOS POST:

After the microcomputer is powered on, the system has a process of checking the internal devices, which is done by a program commonly known as post. This is also a feature of the BIOS.

The complete POST self-test will include CPU, 640K base memory, more than 1MB of extended memory, ROM, motherboard, CMOS memory, serial and parallel ports, graphics card, soft disk subsystem, and keyboard testing. If a problem is found during the self-test, the system will give a prompt message or buzzer warning.

After completing the POST self-test, the ROM BIOS searches for valid boot drives such as floppy drives, hard drives, and network servers based on the boot order in the system's CMOS settings.

The driver for the integrated graphics card is not installed.

Unplug the discrete graphics card and use the integrated graphics card instead, you need to uninstall the driver of the discrete graphics card, and see if the device manager has a yellow exclamation mark, if the driver of the integrated graphics card is not installed, it will not light up.

The BIOS defaults to a discrete graphics card output, and the default settings of the BIOS can be restored by removing the motherboard's battery in the event of a power failure.

The integrated graphics card was not turned off in the BIOS, and the graphics card that is working now is the integrated graphics card.

If you want to use a discrete graphics card, you need to turn off the integrated graphics card in the BIOS.

The graphics card of this motherboard is a CPU built-in graphics chip (CPU support is required), what CPU do you have?

Is the interface right, and is the monitor switch turned on?

You can't coexist with a discrete graphics card and an integrated graphics card on a motherboard.

You need to disable the integrated graphics card in the BIOS first. This way, you can use the discrete graphics card on the motherboard after booting up.

For motherboards with integrated graphics, you need to disable the integrated graphics card in the motherboard's BIOS. The specific method of each motherboard is different (BIOS is different).

Summary. Hello, this happens when the computer is plugged into the discrete graphics card, probably because your computer is using the nuclear graphics card by default and has not switched to the discrete graphics card. Here are a few things you can try to fix this:

1.Check the power connections: First, make sure that your discrete graphics card is properly plugged into your computer's motherboard and that the power connections are securely contacted.

Some graphics cards require additional power**, if your graphics card requires external power**, make sure the power cord is properly inserted into the slot on your graphics card. 2.Modify BIOS settings:

Many computer motherboards offer BIOS settings, and you can try to fix this by modifying the BIOS settings. Once in the BIOS settings, find the "Integrated Peripherals" or "Chipset" tab, set the "Initiate Graphic Adapter" to "PCI-E" or "PEG" mode, save and reboot the computer. Once this is set, your computer will use a discrete graphics card by default.

3.Update graphics drivers: If your computer has a discrete graphics card properly connected and still isn't working, it may be because your graphics card drivers are out of date or corrupted.

Hello, this situation occurs after the computer is plugged in with the sedan discrete graphics card, it may be because your computer uses the nuclear graphics card by default and does not switch to the discrete graphics card. Here are a few things you can try to fix this problem:1

Update your graphics card drivers: If your discrete graphics card is properly connected to your electronics store, but it's still not working, it may be because your graphics card drivers are out of date or corrupted. You can try going to the official **** and installing the latest graphics driver, then restart your computer and try using a discrete graphics card.
