I'm delving into controlling the image (displayed on the screen) at the UEFI level and then the operating system level. But I have lots of questions.

There is GOP (UEFI Graphics Output Protocol).
He appears to be controlling the image right from pressing the POWER button on the computer.
At some point, the graphics card driver takes over.
Is that so? Is there something else going on in between?

So the graphics card is in GOP mode, and then in the mode in which the image is controlled by the graphics card driver?

I am interested in the issue of resolution and refresh rate of the image transmitted by the graphics card to the screen.

How does the GOP control this? Image resolution and refresh rate?
When I turn on the monitor's OSD while in UEFI, it shows 2560x1440 60 Hz.

At some point, probably when switching to the operating system, the screen goes blank for a moment and then comes back with the correct resolution and refresh rate set (2560x1440 165 Hz).
