Two stars for this terrible out-of-box experience. My brand new Mac mini M1 is not compatible with my old DVI monitor using an HDMI to DVI cable. The monitor just displays an error message, "Input Signal Out Of Range".Good news: A thread on a Mac user support site (latest post January 24, 2021) reports that a software fix will be incorporated in the next system update (OS 11.2).Bad news: I have to wait for delivery of a Thunderbolt to DVI cable before I can even set up the computer to install the OS update.Edit (February 1, 2021)I just installed the OS 11.2 system update (4.18 GB, about 1/2 hr to complete).I'm happy that my HDMI to DVI cable finally works properly and my Thunderbolt ports are free for other duties.It will take a while for computers imaged with older versions of OS 11 to flow though the distribution pipeline so be prepared with an alternative to HDMI output if you buy one in the next few weeks.
