Mac mini M2, problem with external display (reopened)

Apple forum close my previous question, but I feel to need share my knowledge about this problem.

First of all, there is nothing wrong with the Mac mini.

1) First step, If you have problem with resolution of your screen (blurry text, dark spaces, white blinking stripes etc.) check the cable or buy better one. Certificated with HDMI 2.0 + normal length (0,2 - 1 m)

2) If the problem still occurred, choose different monitor to test it or buy a new one (I know, nobody want a spend extra money, but in this case is it necessary. For example I buy this one piece and it is working fine -> 32" LG UHD 32UN650-W

3) Use 2560x1440p or 1920x1080p. Other resolution do not make sense.

I hope I help you with your struggle and I am looking forward to your possible comments!
