I personally use my laptop with an external display attached and haven't observed any issues so far.
From my experience, it's better to use gdm, as sddm seems to have a problem detecting the external monitor (more details available here). Of course it's not a blocker, as it is still possible to log in using sddm. I personally find it annoying that my main display remains idle.
Setup at the time of testing
$ nix-info -m
- system: `"x86_64-linux"`
- host os: `Linux 6.1.62, NixOS, 23.05 (Stoat), 23.05.20231116.9fb1225`
- multi-user?: `yes`
- sandbox: `yes`
- version: `nix-env (Nix) 2.13.6`
- channels(beko): `"home-manager-23.05.tar.gz"`
