the monitor also go to sleep like on an iMac?

Also, I assume that when you turn on the mini you also have to turn on the monitor separately? No way to tie the two together?

If it works properly, when the mini goes to sleep, the monitor will detect this and go to sleep as well. When the mini wakes back up, the monitor will detect this, and will wake up too.

Note that some third party monitors don't necessarily always play nice though, so some monitors may have issues with sleep/wake.
 
Yes, mine works just like the iMac. My mini has been running for 8 days now, no issues, but just updated and restarted so timer has reset.

I'm thinking of this: Dell 32 Curved Gaming Monitor - S3222DGM,31.5", QHD, FreeSync Premium, 165Hz, 1ms (MPRT)

When a Mac puts a monitor to 'sleep' all it does is shuts off the display signal coming from the graphics card. Its not an actual control signal. Most monitors when they don't detect an input signal go into a low power mode or 'sleep' until they do, and then everything 'wakes up' and turns on full power. Everything should work just like the iMac does unless you disable it.
 
My M1 Mini has issues waking from sleep. Because of this, I don't really put it to sleep. I just let the monitors go to sleep and not the mini itself. Whenever I actually put it to sleep and try to wake it up, either the magic keyboard wouldn't respond or the monitors wouldn't come on correctly. The backlights would light up but there was no picture. I have to unplug the monitors from the back of the mini and plug them back in to get them to come on. Other times only one display will come on and not both. Kind of a pain, so I try not to put my mini to sleep.
 
I have a different issue with my M1 Mac Mini when it wakes from sleep. Occasionally (very occasionally) it will display a gray, static filled screen instead of the proper image. Usually after a few seconds it goes away, and then the correct image appears. In some cases it's necessary to disconnect the HDMI cable from the mini and then the display is correct.

I got the machine on Cyber Monday, and quickly found this flaw. I took the machine to the local Apple store, with photos of the problem so they could see what I was talking about. Intermittent problems like this are the worst to figure out. They first replaced the "I/O wall" and that did not resolve the problem; they saw the gray screen themselves while testing the computer. Then they replaced the logic board, which took several weeks as it is a BTO machine with a 1TB SSD and 16GB memory. I got it back yesterday. This morning it game me the gray screen when waking from sleep again. I'm continuing to test it to see if the problem is really back, along with some other unrelated configuration issues. The only thing left to replace is the PSU, and those are involved in power management/sleep issues. If that is done I'll have a complete new machine. But it is new from only a few weeks ago, anyway.

My testing has of course used several different HDMI cables and displays to rule out those items.

Aside from the frustrating video problem when waking from sleep the Mini has been very nice indeed. Just a bummer that it seems that it may still not be fixed.

Has anybody else had video problems with the M1 Mini?

Why do you use the HDMI instead of the USBc?
 
Well, the Mini has that video output and only two USB-C / Thunderbolt connections. So using HDMI for video saves the other I/O connections for things that cannot be done with HDMI. I use one of the USB-C/TB ports to connect a TB dock, and that has an HDMI port, among other connections. Using that HDMI port did not cause any problems in earlier testing. It also seemed just a shade slower to wake than using the native HDMI port on the Mini itself.

The displays I'm using are rather basic and it is possible that if you are using a high performance display then connecting them via USB-C / TB would be sensible. But that's not the case with my displays.

I set up my new M1 where the monitor falls asleep after 30min and keep my Mini on without the HDD turning off.

I occasionally have this 'static' issue along with random blackouts lasting about a second on my HDMI-connected monitor. I have no sleep issues with the monitor connected via Thunderbolt to DisplayPort.

When I put the machine to sleep, I do notice that the monitor connected via DisplayPort will go black, but the backlight stays on, whereas the HDMI monitor's backlight shuts off. I think this is maybe some sort of problem with sending proper CEC commands; it could also be because that monitor is connected through a CalDigit TB hub?

FWIW these are Dell P2415Q UHD displays. I run them at the recommended scaled text size. I don't really do anything strenuous with the computer, esp nothing graphically intensive.
