Windows 10: Monitor refresh 144hz - but one time booted with lower value.

Hello.

My pc: 6700K stock
*16GB DDR4
*Asus Z170-P
*Corsair 750 RM
*Gtx 1080 Ti Founder Edition
*Monitor Red Eagle IIyama 24' 1080p 144hz plugged by display port cable to GFX.

Maybe this is coincidence and i am worrying about nothing.Few days ago on afternoon 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.That happened just once. I remember that this day i had power outage in morning. This was related to power outage or it was coincidence? I tried to reproduce 2 times by powering off pc and powering on and booting again, but 144hz on start. Not able to reproduce.

Windows just allows the setting the video specifies so it really is not directly involved.

That has to be power outage related. The computer's power supply or the video card likely had to reset which tool another boot cycle to initialize. Of course that is just a guess. If you need more info then you really need to be working with the hardware folks
at ASUS. IIyama, and GeForce.

Yeah but i want to reproduce this issue. So i cut power off 2 times . And i booted few times pc without this issue. I mean there was always 144hz during each boot. So?

 

Depending on how close these two occurrences happened, it may be a fault in the Nvidia driver. Are you running the latest revision, even if its a game ready driver?s

Just wondering why on first boot ( after power outage ) refresh was normal at start 144hz. It happened when i manually turn off computer and turn on again,and on my second boot it happened. Refresh was lower than 144hz. To make again 144hz i turned off monitor and turn back on again. And after this never happened again, even if i tried to reproduce by cutting power off manually.

 

Hello. I apologize for my language,hope you understand. So yes.

My monitor is always on (standby) before the PC is powered on. Thats the first thing. Second.

When i run pc first time on first boot ( after power outage ) refresh was normal at start 144hz. It happened when i manually turn off computer and turn on again,and on my second boot it happened. Refresh was lower than 144hz. To make again 144hz i turned off monitor and turn back on again.
So that was bug or that power outage related? But i like i said on my first pc run ( boot ) after power outage refresh was 144hz fine. It happened just after i normally shutdown my pc and booted pc second time.
Maybe coincidence and i am worrying for nothing,hehe ?

Ah. I tried to reproduce only 3 times by cutting power to pc and powering on and booting again, but 144hz on start. Not able to reproduce.

ps:
Power outage was because fuse was tripped because of kitchen which was turned on in other room. That does matter maybe?
