    2, the graphics card is faulty, the graphics card is removed or the graphics card is replaced.

    5, the motherboard is faulty, change the motherboard.

    Check the contact problem of the line. When the screen is displayed, it is normal. If the display is normal, it will only display slowly, or the black screen should be bad after display. The circuit is not big. The capacitor may have exploded on the board.

    Send the repair shop to check if the graphics card and display are damaged, and replace the hardware.

    Try changing the monitor to see if it is a monitor problem or a machine. You can also change the line between the monitor and the chassis to check if there is a line problem.

    Question: No extra monitors
