Is my monitor dying?

[***F1ZZY***]

I have a 1440p VA curved panel 165hz TUF gaming monitor from ASUS. Model VG27WQ. It 3.5 years old and just out of warranty. (Typical!)

It’s connected via DP to main PC and I also connect it to work laptop via HDMI when I WFH.

DP used to run 165Hz in both desktop and games. Now I cannot get it above 100Hz

HDMI used to connect at 144Hz now only will do 120Hz.

I’ve ordered a new DP cable but not sure it is that.

Is my monitor starting to die a slow death? I’ve not had one fail like this before.

Thanks

Resolution is native 1440p. It is the refresh rate that has diminished.

Both machines no longer can hit the previous refresh rates. Windows display settings, or nvidia controls on main pc, no longer have higher refresh rates available.

Yes it is confusing.

Also occasionally it goes black for a split second. Both sources do this. But very occasionally, maybe only a few times a week.

I have raised a ticket.
Thanks

Good shout on the only other common link to both sources being windows. They’re both on win10. I’ll have a look and see if I can find anything.

Update - it seemed to fix itself, so perhaps a windows version issue that was resolved. In the meantime I treated myself to an upgrade and passed this one to my son. Double win.
