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

[sewerino26]

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 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. This was related to power outage or it was coincidence?

My Dell S2716DG will sometimes do this and be stuck at 85Hz. I reboot the PC to fix it, didn't try turning monitor off and on again.

I have a GTX 1080.

Can you tell me when this happens? After Windows 10 startup boot?

Really sorry for my language. If i can i explain this more clearly.

Few days ago I get power outage.

Pc was running in fire strike benchmark with monitor ON. At the same time my mother was powering on electric oven in kitchen. And then power went out in house.

Just before power went out, pc was running in Fire Strike test, and monitor was on. When power went out,pc goes off and monitor goes off.

When power back ,monitor turns on itself . Then I booted pc , all was looking fine, Windows 10 booted with 144hz

But after moment I shutdown pc by clicking shutdown in Windows 10 and I manually turned off monitor. After 30 minutes ,first I turn on manually monitor,then I boot pc again. Windows 10 booted with lower refresh than 144hz.( on nvidia panel still 144hz ) To restore 144hz I just turned off monitor and turn on again. And this not happened since.

And my question. It was related to this power outage or just coincidence?

And I am not able to reproduce. Turning off pc few times and booting again,and nothing,still 144hz. Even I cut power 3 times to check,but still 144hz on boot.

So maybe that was glitch.windows,system,drivers or something but not related to that power outage? Or maybe power outage was the reason, but the problem didn´t show up immediately?

Yes i am using cable that came with the monitor and is it displayport.

First pc boot ( after unexpected shutdown in event logs due to power outage ) was fine, Windows 10 booted with 144hz refresh. But for a moment i turn off pc normally by clicking shutdown in Windows 10 and turned off monitor. After 30 minutes i booted pc second time and windows 10 showed lower refresh than 144hz. I mean on nvidia panel was still 144hz. But i see that on screen are lower refresh.
To revert 144hz i just turned off monitor and turned on again. So propably coincidence?

So it was related to power outage , system or something with monitor firmware?

 

[sewerino26]

hmm ok

 

[sewerino26]

Ok i know you say for sure that i am stupid, but i agreed. I cut power to pc few times to reproduce issue exactly like on this day. But i cant reproduce. Pc booting and restarting exactly with 144hz.

So why it happened just once? Can somebody explain me? Something related to outage or just random glitch?

 

[sewerino26]

So that was more driver/windows/monitor firmware?! more related that voltage spike?
Like i said i just turn off monitor , turn on again and 144hz appeared again.

lol 2 pages. Thank you for replies. Also this will be my last question.


When i tried to reproduce issue , i cutted few times power and i cant reproduce. Pc booting ,shutdown,restarting with 144hz still.

So it was related to that outage because fuse blown or just random glitch ?
Is this because fuse blowed or that doesnt matter ?

But like i said i tried to reproduce this by cutting power from power cord and i am not able reprodue. So it was related to that outage when fuse was blown or just coincidence and fuse doesnt matter?


To be more precised. My mother turned on oven in kitchen, and bulb inside oven melted. Fuse of course blown and i got that power outage.
