Hi everyone, I am new to the forum as well as new to the mac world. I have purchased my mini last week, so far everything seems okay until I realize that sometimes my Mac Mini does not produce any images on the screen. (Note that the screen shows no signal from the cable). I am pretty sure everything is going okay with my HDMI cable and my monitor. The issue occurs when I tried to wake my Mac Mini from sleep. In order to get image from the screen, I need to force shut down my Mini, disconnect every cables attached, and reattached it again. And then after some trials it will start to produce image on my monitor. (I am using a 22" Samsung LCD HDTV anyway) I also have upgraded my Mac Mini to its latest firmware. Does anyone experience this issue? Should I contact apple and demand for a new machine? Thank you in advance!
