Hello. I am just asking. Maybe this is coincidence and i am worrying about nothing. So listen... 2 days ago after turning on kitchen, fuse was tripped and i get power outage. When power back after this i booted pc fine but i saw that Windows 10 desktop refresh changed itself from 144hz to lower value ( i dont remember to which ) . To restore again 144hz , i turned off monitor ,turned again on. And its fine. Why that happened? I tried to reproduce this issue, by turning off computer and booting again but it never repeat. And my question is . That was coincidence that after power outage my Windows 10 monitor refresh was changed or not? Thank you. My pc: 6700K stock 16GB DDR4 Asus Z170-P Corsair 750 RM Gtx 1080 Ti Founder Edition Monitor Red Eagle IIyama 1080 144hz plugged by display port cable to GFX. I tested games etc etc and no crashes or artifacts.
