After installation, monitor goes into rlow-res mode

I have problems installing Manjaro 21 because after a while without even finishing the updates, an error appears, the monitor restarts and when turning on its resolution is reduced and in the screen settings it is not allowed to change it in any way, not even the Hz, I need help with this, also a box appears that says “input not supported” and it goes through the whole screen …

:+1: Welcome to Manjaro! :+1:

  1. Please read this:
    [HowTo] Provide System Information
    and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…
  2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
    Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.
  3. A problem with something can definitely be solved by doing a thing! :grin:
    I.E. The exact error message would be more helpful. :wink:


P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you’re using, which CPU/GPU or Kernel, … you have without typing it every time
