Modern notebook computers generally use the function of automatically switching the use of graphics cards.Under normal circumstances, they will give priority to the integrated video card, while when running specific software or games, they will switch to the independent video card.This switch is completed at the operating system level. By monitoring task requirements and resource allocation, it can determine when to switch to which type of graphics card.This helps improve performance and ensures that the system meets user expectations for graphics processing requirements.
There are two reasons: 1. The Nvidia display is disabled. 2. There is a problem with the display drive. Corresponding solutions: 1. Enable the video card through the Device Manager. Right click Computer on the desktop to select Manage, click Device Manager, Display Adapter, and Nvidia Video Card, and then right click the video card to select Enable.
2. If there is a problem with the driver, update the video card driver in the device manager. It is the same as step 1. Right click the Nvidia video card, select Update Video Card Driver, and update the video card driver according to the prompt.
This prompt appears because the signal line of the display on the host is connected incorrectly. Your computer should be equipped with dual graphics cards, with independent graphics cards and integrated graphics cards. Nvidia graphics cards are your independent graphics cards. The current configuration should connect the display to the integrated video card, so the independent video card has no output, and of course, it is impossible to set. Connect the signal line of the monitor to the display interface of the lying independent video card on the lower side of the chassis, and then it will return to normal after startup.
