Strange power issue with Dell monitor

[mattyfez]

So my monitor has been great for several years..

I can't remenber the exact model, but it's an S-series 27" IPS, 1440p, 165hz, freesyc premium, & HDR400

Once or twice over the last few weeks it's just lost power, like out like a light and struggles to turn back on... no other symptoms.

The rest of the PC is running fine, the speakers are seperate but plugged into the same 8 gang belkin extension cable brick that the PC and monitor are plugged into, PC is still on, internet radio still comming through my speakers.. its almost as if someone just unpluged the power cable for the monitor. Black screen, power button on monitor unresponsive.

I've resolved it by turning the whole lot off at the wall and reseating the monitor kettle lead and DP cable and it randomly works fine again.

I'm at a loss as to whats causing it though.. bad kettle lead or DP cable? bad power button on monitor? bad power brick?

Thanks.. I'll give the firmware update a go when I get chance.. The problem has only occurred once or twice in the last few months, but I have noticed a bit of strobing when playing forza horizon 5 in a semi regular basis.. But that's a fairly recent phenomenon too...

I put it down to the HDR getting confused somehow as it only seems to happen in that game.

I've never updated the monitor firmware since new so that seems like a sensible place to start..
All though these issues have not existed all along... They are very intermittent and only manifested in the last year or so...

Yeah im running freseync as I have an AMD graphics card...

**but it only seems to hapoen in forza horizon 5***

and I think i run that at uncapped frame rate @120hz.. i could try capping the frames at 90 or 120 or something

It might well just be windows 11 being a spastic with HDR... but there are too many variables to confirm... just to provide some more detail...the monitor doesn't switch off when in active use, but if it goes to sleep, it just won't wake up again, like it's dead, but it's not...

I'm thinking its a windows HDR issue.. but equally ive never updated the firmware on the monitor, either... so I will do that first I think
