Setting a custom scaling factor

So what im trying to understand here is how the custom scaling factor works.

I set my custom scaling factor to 100% and turned off the "let Windows try to fix scaling for apps" feature.

Now my desktop looks the exact same (as expected and wanted) but my mouse movement feels different. The scaling method i used before was the default windows 100% scaling, so the reason for me setting this custom scale factor was infact to achieve different/better/more accurate, mouse movement.

When i open my display settings, the scaling section is greyed out. This is all well and good but in that greyed out section, it says that i have a scaling of 175%.

Why is this ? I have checked in my advanced scaling settings, and there it says i have the 100% that i put in. And the scaling of the desktop looks nothing like 175%.

So im curious as to why this happened, and i dont get how my mouse movement feels different (which it does). When essentially i changed the scaling factor from 100% to a custom set 100%.

And as for the "let windows fix apps so that they are not blurry setting" what does it do in terms of dpi scaling ? does it make an application run in the default dpi that the windows desktop runs in ? or does it do the opposite, by which i mean change the dpi to whatever looks good. This is important for me because i figure any application using the default scale/dpi of the desktop should have the most accurate mouse movement, which i what im looking for. So i would rather have a blurry application with accurate mouse movement, as opposed to a crisp and sharp one with inaccurate mouse movement.

I use the 6 out of 11 option in the mouse sensitivity setting, and i have "enhanced pointer precision" turned off.

In my Nvidia control panel "adjust desktop size and position" tab. i have it set to aspect ratio scaling/perform scaling on display/and the override scaling mode set by games and programs option, is set to off.

Also curious as to how the Nvidia desktop scaling features interact with the windows scaling features.

any answers are appreciated

 

"A CUSTOM SCALE FACTOR IS SET"

Window 10 - After last week update and recovery back to previous version losing all software and app, the scaling custom scale factor still is set and not coming back. There is no responding on the resolution tab to change
the screen resolution, there is nothing responding that you can try after reboots and updates, and you can barely see the letters.
