I also thought that, as I do have a 32" 4K DisplayPort monitor with plenty of scaling options presented in macOS (and even more options if you hold Alt/Option while clicking the "Scaled" radio button). On other monitors with macOS I have sometimes not been given scaling options. I'm not entirely sure what the rules are about when or when macOS doesn't show scaling, so maybe there is something with the laptop model/Thunderbolt -> HDMI adapter/monitor that is catching him out. Aside from that I definitely agree that 32" is not for everyone and I'm not sure if I would buy it again.
