IIAMA refresh 144HZ -soon after power outage booted with lower value

[sew999]

Hello.
My pc:
*Asus Z170-P with 6700K cpu

*Corsair 750 RM

*Gtx 1080 Ti Founder Edition

*Monitor Red Eagle IIyama 24' 1080p 144hz plugged by display port cable to GFX.

Few days ago i get power outage.

Pc was running in fire strike benchmark.
At the same time my mother was powering on electric oven in kitchen.
And then power went out in house.
Then she go to shop and buy new fuse.
Later a friend replaced fuse and power back on in house.

When power back. I booted pc first time and all was fine, refresh 144hz . But then i turn off pc . Go rest to bed. After 30 minutes i turn pc on again. And then windows 10 booted with lower refresh than 144hz. To revert 144hz i turn off monitor and turn back on.

So conclusion: It happened not just after ( not on pc first power on ) power outage.
But on second time ( second turn ) when i boot to Windows 10. On my second turning on pc, second boot to windows. So not immediately after power outage.




Just on my second turning ON pc after power outage, it happened. Thats all.

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 or something but not related to that power outage?

My drivers: 388.13

If it just happened one time I wouldn't worry about it at all. Just sort it in under oddball things that happen sometimes when combining multiple components from multiple manufacturers, all running complex software that may sometimes interact in "interesting", strange ways.

Somebody said:" I would think the monitor has suffered a voltage spike or even under voltage and maybe damaged. If the monitor keeps reverting to a lower refresh rate when turning it on after a period of time of being off or after the power goes out repeatedly it could be only the beginning of problems especially the keeps dropping out inexplicably."


So what my monitor is damaged?
