Well, that's the motherboard, not the videocard. Every motherboard does it.

Yep, that's through the BGRT, which is part of ACPI. I'm not actually sure if a GPU could export one to the BIOS, but I assume not.

The connection to the monitor is physically located on the video card. So the gpu could display whatever it wants without asking or coordinating with the motherboard.
