Why does the monitor flicker when I connect an Acer monitor to my Acer laptop?

Question

Video cards

Hello, I have a problem and I would like to find at least some solution. There are guesses what it is, but suddenly there is a hidden problem that is solved much easier.

Background/situation:
The company bought a laptop in DNS, namely Acer Aspire A515-55. Immediately upon the first connection, the monitor started flashing, the same company Acer - it is also new, less than a month (I don’t think this is useful info, but suddenly

)
.
Obviously, comp. (the wires also checked everything) Drivers are not the same? Something is missing? This may be due to the fact that Windows is not orig from the very beginning?
The drivers were reinstalled, alas, this did not help, but I'm afraid the drivers might not be the same.

p / s The monitor blinks when you press the keyboard, it feels like the computer switches from one monitor to another at some point when you type and there is a 2-3 second blink. Then half an hour an hour may be nothing and hop .. again.
At the end of the working day, the feeling that it blinks more often.
