Hello i have mac mini 2014

its connected to the samsung smart tv by hdmi (i tested 2 of them)

When mac boots up on the screen i saw multiple artifacts (artifacts similar to analog tv)

When osx power off screen the problem also persists
I see artifacts alternating with a black screen and after some time the image appears

while booting I can not see anything beyond the artifacts (I can not choose between osx and windows)

if anyone had a similar problem?
