Same issue with external monitor in Ubuntu 20.04 LTS, Fedora 39 (KDE plasma) and I observed it with many other distributions (e.g. Lubuntu 23.10). With exactly same setup, Windows 10 Pro on my lenovo T470s with external monitor does not give any issues, so, not a HW problem. Tried xset -dpms, sxet s off did not really solved the problem.. better say this WA did not help at all.
