    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?
