Wrong resolution for first 30seconds after boot on Windows 10

Every time I boot my Windows 10 computer, the screen displays with the wrong resolution for the first 30 seconds before switching to the correct setting, and this issue happens repeatedly. Additionally, I have experienced a second failed attempt at installing a Windows Update, which has left me unsure about whether the resolution problem is related to the update failures or a separate issue. I am looking for advice on how to fix the initial resolution glitch during startup and resolve the recurring Windows Update errors to ensure my system runs smoothly.

    When you boot Windows, the system first uses a basic generic display driver. After about 30 seconds, your actual GPU driver loads and switches to your correct resolution. The delay means something is slowing down the GPU driver initialization.
