For a few seconds, both then one monitor are cut down at once, what's the problem?

Question

Computers

Hello.
I have 2 monitors connected via HDMI to the video card.
When I open the working software and start working, one monitor stops displaying images (darkens) although it remains on (the power light is on). Sometimes both go dark at the same time.

Can the problem lurk in a weak power supply, such as during operation, due to increased power consumption, there is not enough voltage for the video card, which can cause the monitors to darken?

Answer 1

well, if the problem is only in software with a high load, then either the power supply is not enough or the video card is faulty
