Scaling changed after windows format

[Evellence]

Hello!

 

A day ago i formated my PC, my scaling has changed, even tho the numbers are same before and after formating, they are both set to 100% in display settings. But things are smaller now and 125% is way to big for me. 

Now that doesn't really bother me that much. I can get used to this in few days. The main problem is somehow that affected sensitivity in games, its way off and a lot slower. Even tho my mouse DPI settings and game settings are the same as before. 

 

I really need help with this. Is there anything else i should do before i start guessing the number with custom scaling option? Is that even the problem? Any why would that affect mouse sensitivity? 

 

Thank you and have a good day

Did you properly reinstall your GPU's drivers after formatting?

Is the monitor set to the right resolution? Does Windows properly recognize your monitor for what it is (refresh rate, resolution, etc..) ?

Yes i did install GPU drivers properly. 

Monitor is on right resolution 1920x1080 @144hz, and windows does recognize it.
