nv4_disp.dll is an important file for Nvidia graphics card driver. You need to update your N card graphics driver.

It is recommended that you download it from the manufacturer of your specific hardware device or Driver Home And install drivers with Microsoft WHQL certification.

If you really can’t find it, just download a driver wizard or driver life, which will automatically help you find the corresponding driver when connected to the Internet. (Note: Be sure to download and install the driver that has passed (WHQL) certification. Driver.)

Appendix---Microsoft's instructions on driver blue screen: The driver is not digitally signed, which means that the driver has not passed Microsoft's Windows Hardware Quality Laboratory (WHQL) testing. Installing drivers without digital signatures can cause instability in the operating system and even cause a blue screen of death. You can obtain WHQL-signed drivers from the manufacturer of your hardware device.
