Why not display intermediate information when you turn on the computer and his endless off?

Welcome. When you turn on the computer all the intermediate information (Boot Setup, etc.) is displayed only on the projector (EPSON in this case). Even after disconnecting the projector, the intermediate information is not displayed on the monitor. Changed the priority of the display (did the monitor display main). The monitor is connected via HDMI to graphics card (Nvidia 1660). The projector is not connected to the graphics card, i.e. through the Mat. cost to the processor (I am not sure whether I expressed about the projector's connection).

There is also a second problem: the computer does not turn off. Monitor goes into sleep mode as it should, and the computer continues to work. I googled about this, tried several ways, but to no avail.

According to disable FastBoot in the BIOS and there look for the setting that is responsible for displaying information when you boot. Something like "Show POST screen".

Update the drivers, Wang, that the problem is in the chipset driver (specifically the ACPI driver). Use SDI.
