You probably need to contact the manufacturer and ask about settings that can be used to control the screen.

Unfortunetally i bought IT as used from other person.
Any entries to config.txt could help?

HDMI blanking is a Raspberry Pi OS function. I’d suggest trying the Raspberry Pi Forum. There’s already at least one old thread there about one user’s blanking issues with different Pi models.

Looking there and found some similiar topics but its about no signal for 1sts seconds even on boot.
