Open Device Manager (devmgmt.msc).

Expand Display adapters.

Right-click your GPU (e.g., NVIDIA GeForce RTX 4090) and select Update driver.

Choose Search automatically for drivers.

If no updates are found, visit the NVIDIA Driver Download page to manually download and install the latest driver.

Restart your computer and check if the issue is resolved.
