    For some time (I suppose that after installing the latest nVidia drivers), from the moment I turn on the computer to the moment when the desktop appears, I have a black screen (as if the monitor did not respond to the signal from the computer). Only after the desktop is started, the screen catches the signal. I have connected to the graphics card:
    1. DisplayPort -> monitor
    2. HDMI -> TV
    I didn't have such problems before :/
    Sure, pulling HDMI out of the graphics card solves the problem, but I'd rather get to the right source of the problem. I am asking for suggestions, what could be the reason? :(

    Greetings :)

    You probably already told yourself what the problem is. Namely, newer cards or drivers block/delay the signal for a certain time and the result is a black screen, in other words - no information is given to the screen to display anything.
    If there was no such problem with the older cards/drivers and you liked the situation, you should use the older card/driver.
