Does the built-in Intel video card only work if you turn off the computer from the network and turn it back on?

Question

Iron

Asus Rog Strix Z270E Gaming, my built-in video card only works if the computer is turned off from the network and then turned on again. Previously, this was not the case, it used to work fine, I have several monitors, and sometimes I need to change the connectors and connect an additional monitor to the integrated Intel video card. So, the screen will be NO SIGNAL. In order for it to work, you need to turn it off for a couple of seconds from the network, and turn on the computer again, just rebooting does not help, as well as turning it on and off.
With what it can be connected?

Answer 1

There was such a thing with the outside, I still have not decided.
