Is it possible to get display scaling in Sonoma?

I am installing a 2018 Mac mini with Sonoma, connected via HDMI to a 49" Sony Bravia 4K XBR-49X900E TV.

In Display Settings when I set resolution to

• 3840x2160 I get a 4k display image ... nice
• 1920x1080 (default) I get a 1080 display image ... also nice but not 4K; there *is* a visible difference

How can I get a scaled image on 4K in Sonoma? All the text & windows are tiny. There is no scaling option in Display Settings.

Another user posted a claim earlier that by setting resolution to 1920x1080 (default) you would actually get 1920x1080 scaled on 3840x2160 resolution but I do not find that to be true. I checked System Report for each resolution and this is what I get at each setting ... looks like it's either "true 4K" or "true 1080," no "scaled 1080 on 4K."

No setting yields Resolution 3840x2160 with UI Looks Like 1920x1080 as claimed in the linked thread.

At 3840x2160 setting:

At 1920x1080 setting:
