[Solved] Monitor blinks - one second there's a picture, one second there's a black screen

Hi!

PROBLEM: Dell laptop with Win10 I connect via HDMI-HDMI cable to LDC monitor 24" Iiyama ProLite B2403WS . Image on the laptop normal, on the monitor for a second it shows, for a second it disappears, I see a black screen. This kind of blinking goes on all the time.

Laptop I previously attached to this monitor, with the same cable, with the same settings. There was never a problem. The problem suddenly appeared this morning.

I checked the HDMI cable. On a different cable the same problem occurs with connecting the laptop to this monitor.
I checked the monitor's performance - I connected it to my desktop computer with the same HDMI cable - everything works without a problem.
Just yesterday I connected this laptop to another LCD monitor, with a different HDMI cable - everything worked without a problem.
I updated the graphics card drivers on the laptop. It did not help.
I changed the resolution and refresh rate - the monitor continued to blink.
Tried pressing the plugs, moving the sockets. No effect.

I have no idea what is going on.
Anybody can help?

Not long after I started the topic, I found the solution.

Probably the monitor software went crazy. The flickering was due to the embedded software's attempt to match the displayed image to the monitor.
1. I gave the laptop image display only on the monitor.
2. I unplugged the monitor for several seconds.
3. I plugged it back in and the image stopped blinking. It already works normally.

Previously turning the laptop/monitor on and off did not work.
Problem solved.
