Windows 10: Windows Scaling - Does this Defeat the Purpose of a 4K Monitor?

Hi, I recently upgraded my monitor to 4K and noticed that Windows Scaling shows the value of 150% as Recommended. Leaving it at 100% is super crisp, clean, but small - the upgraded resolution is obvious. But I find that 150% almost looks like a 1080p resolution... and am curious if setting it to that defeats the purpose of having a 4K monitor. Meaning, am I dropping the monitor's resolution by using any scaling above 100%? And why would Windows suggest 150% if doing so downgrades the quality of the HiDPI? Just doesn't look super high res to me anymore at 150%... is it just me?

:)

I have my scaling set at 175% and the 4k desktop wallpaper looks very sharp as do 4k videos. Most 4k TVs are significantly more than 50-75% larger than my 27" 4k monitor, so 3840x2160 graphics are spread out much more on them.

 

Scaling Issue With Extended Monitors

Recently got a new 4K monitor. It's running at 4k with 150% (Recommended) Scaling. I want THIS monitor to be my main monitor. It is centered to my setup and is the MAIN monitor I will be using, etc, etc. My old 1080p monitor has a recommended scaling of
100%. This is what I had been using for years and is most comfortable for my eyes.

My issue is:

Apps are blurry on the 1080p monitor; i.e. Apple Music is blurry.

The 4k monitor is just fine.

I can fix the blurriness by setting the scaling higher for the app itself in (app)>properties>calibration>DPI settings

I can fix the blurriness by setting my old 1080p monitor as my main monitor, and having windows fix the blurriness by turning that option on. This keeps the normal scaling and looks great. Only issue is that I want my Main monitor to be registered as the
Main monitor in windows settings so that all of my information and app work is prioritized there.

I can also fix the issue by setting both monitors to the same scaling, but that defeats the purpose of scaling. One is a huge 4k monitor and one is a 1080p I do not want massive text on one monitor and tiny text on the other. Rather ridiculous.

Why does it seem that the only fix I am looking for has to be done by first setting my old monitor as the main monitor? If I could keep my main monitor as my main monitor with the benefits of the blurriness and scaling being fixed then my question would
be answered.

Thanks for any help.
