Translation:

On Mac mini M1 after the last OS update (Sequoia 15.3.1(24D70)) the system does not see the second monitor, if you connect the monitors in turn, both work, but not together

What monitors and how are they connected to the M1 Mac mini..?

Have a look at > If your external display is dark or low resolution - Apple Support

Apple Thunderbolt 27” connected with original thunderbolt 2 to display port and Arzopa portable monitor connected with hdmi, they both worked well before update, the problem is definitely in software. I see such picture after reboot, but when I enter the password and system is unlocked second monitor became dark and system don’t see it in system preferences

Your image is confusing, it shows a login screen on the Apple display and a startup screen on the portable display...?

After the Mac mini is fully started up, try unplugging and replugging the HDMI cable in the back of the Mac mini

Solved! I wrote to support and they lead me to delete 2 files from libraries, unfortunately I didn’t save the names of files, something like com.apple.windows.monitors… but Im not sure its correct, write to apple support, they answered very fast and problem was solved for 5 min
