I have a Dell optiplex 790 i3 4g ram 3.3 processor 250 HD was made in 2012 and it runs on windows 11 it will not run a Dell monitor 7 years newer though. It mention you need 5th generation not sure why as a Dell optiplex made in 2012 sure not high enough generation . I go by what Microsoft says 1gz processor 4 GB ram and 250 HD.
