The monitor turns off during operation, what is the reason?

Question

Video cards

Good day! For about half a year I have been suffering with the following problem: sometimes the picture disappears on the monitor for different time intervals. In this case, when the picture disappears, the monitor does not go into standby mode.
Video card: radeon rx 460 (was) radeon 5500xt now
Monitor: budget acer, xs model :)
Connected via hdmi
There are no errors in the windows log.
My observations: the image disappears 7 times per session at a random time and for a random period of time. It can disappear 7 times in an hour, or maybe 7 times in 8 hours. The more actively the picture changes (watching a video or playing a game), the more often the image disappears.
It feels like the monitor just turns off, video and games do not stop.
I tried to change the video card, wire (hdmi) and connect a TV instead of a monitor, it does not help.
Need help with this magic :)

Most likely it's the cable, change it to another shorter one.
