Bought a Mac Mini M4 in Dec. 16 mb Ram, 250mb SSD, 2 TB External. Sequoia 15.2-15.3. My Mac Mini will suddenly go solid black while using it. Lasts for about 2-3 seconds and is fine with no changes afterword. I upgraded to 15.3 and it still continues to do it, maybe 1 or 2 times a day. Not a real detriment to using it but...

It does depend on the quality of the monitor, but HDMI is, first and foremost, a TV connection. And by quality, I mean cheaper monitors often limit HDMI to the original HD resolution of 1920x1080, regardless of any higher resolutions the monitor can support under a DisplayPort or USB-C Thunderbolt connection.
That, and over the years, I've seen far too many posts here by folks trying to use HDMI. Issues which disappeared when they used their monitor's DisplayPort option.
I have an EIZO monitor that allows me to use DisplayPort, USB-C or HDMI. Given the cost of these monitors, I know HDMI would work (with a proper high speed HDMI cable), but I'm still going to use a connection meant for computer monitors before I'd even consider HDMI.
Having an HDMI port is intended for video work. It eliminates the need for a break-out box. You use DisplayPort or USB-C to a monitor for your work screen in Final Cut Pro, Avid, Premiere Pro, DaVinci Resolve, etc., and a separate HDMI output to a reference monitor (TV) to see how color will appear on a TV as you simultaneously work in your video editor.
Same problem with my new Mac Mini M4. I'm up to Sequoia 15.6 and it still happens. Tried different HDMI cables. No help. Seems like it is a Mac Mini thing, or Mac OS thing? I hope an OS update can fix it. Otherwise are we looking at a lot of recalls or repair?
Will try that. Should be here tomorrow.
FWIW, there are two different Anker 8K cables. I went with
B08MZYQ43S
Anker HDMI Cable 8K@60Hz, 6.6FT Ultra High Speed 4K@120Hz 48Gbps Ultra HD, HDMI Cable Support Dynamic HDR,eARC,Dolby Atmos,Compatible with PlayStation 5,Xbox Series X,Samsung TVs
mainly because it had more reviews and slightly higher rating.
I ended up buying the hdmi cable you referenced, because I was having the same issues. After 2 weeks of no issues, the screen blackout came back. I also lowered the screen refresh rate to 120 from 144 when I installed the new cable. I have an Acer curved monitor and also a PC attached to it as well as the Mini, but the PC never had any issues, even at the highest refresh rate.
Any ideas?
Had monitor connected to an older Mac Mini, worked fine, and has fixed cable, can’t replace.
Does not have a Display Cord. Somebody else was also having blackout issues that replacing the unit didn’t help.
I have the same issue. Plus, occasionally, when waking up the Mac the monitor wakes up but the screen remains black. Only way to get it working is to unplug and plug the HDMI cable.
Why?
Beats me. Not a major issue…yet.
FYI - I was replying to Kurt's message asking why he suggests not to use HDMI.
Got you. Did it again when performing a random act.
Viewsonic 22 “ HDMI LED VX2250 series.
Good to know before investing in new cables!
I'm beginning to think this is an issue with the M4 platform and not a monitor cable issue.
Can you please advise me I am a novice with the cables, having the same issue -- is it usb c thunderbolt on both ends and exactly where do you plug it in on the Mac m4 and the Dell U2724D?
