I just got an on-screen error message saying an abnormal thermal behaviour has been detected please contact dell support"".
Its not even hot in the room(24C with windows open). Monitor not obstructed, on a monitor arm well away from the wall. Running the latest firmware(M3B107).
Did anyone else got this error?
Seems like a few others have reported this to dell but no response in their forums asking to contact them via chat.

They might even give you a upgrade :D. So contact them asap. UPS will deliver you the replacement, then UPS will collected your old monitor the day after.
No hassle, I have done the replacements over a many years, this is why i like DELL. I taken out 5 years advanced exchange and it has worked well for me.

Ahh jolly good. Will give it a try :)
 
Dell responded, asking me to factory reset the monitor. Which I did.
I didn't see the error again, but the monitor now goes blank randomly for a few seconds. I can hear the background activity going and it is just the monitor going blank(as opposed to PC). Checked the cables, drivers, updates etc.
After reporting this new symptom, Dell agreed to send a replacement!

I wonder if they send a refurbished one or a new one(or an "upgrade").

How did you get on with this?
I've just had the same message, but the monitor completely locked up, so had to unplug it to factory reset it.
 
After I reported the monitor going blank they offered a replacement straight away. I was apprehensive and holding off for few days as I was/am concerned about the condition of the replacement. My current screen is of impeccable quality apart from the error msg I got only 1 time. And the screen blackout didn't happen after. But after contemplating for few days I agreed to the replacement.
They asked for the serial number at the back, the invoice, and a picture with my name, date and time written showing the serial.

It's arriving tomorrow.

Will see how it is.
 
When my DW was replaced after the 1st died, the replacement was brand new, however the replacement had marks on the screen from the bubble wrap, quite annoying
 
Update:
UPS delivered the replacement. Less than 24 hours from Dell booked it in!
It came in a brown box.
I was told it is going to be only the monitor and no cables - but I assumed no base and arm as well. But to my surprise they were there as well. Which kind of makes sense as not all users will have this mounted on a monitor arm like me.

My original monitor had the manufacture date of May 2023.
Replacement is of Jan 2025 - and it looked brand new with no marks etc.
I was super careful when peeling off the tape from the front cover, as it left some residue last time.

Had a quick look at the self-diagnostics and all seems good like the original. Had the latest firmware already. Can't hear any fan noise(just like the original)
Will do some gaming later tonight/weekend to check further.
 
Good news ^

I called Dell this morning ref the same problem you had, and UPS already have my replacement and it’ll be delivered tomorrow morning.
I certainly can’t fault the service, although it felt a bit sketchy having to write my name, date and time and take a photo next to the monitors serial number, but it is what it is.
10/10 Dell.

@Avathar77 I’ve not received and instructions on how to return my old monitor, are there any in the box or do Dell email me such?

The box contains 2 x A4 papers. One with a notice saying there is no cables included(in multiple languages).
The other piece of paper is "Return Instructions". But only shows us how to reuse the brown box and protective material that comes with the replacement to pack the original unit. It does not say how to book a carrier for the replacement. I can only assume that Dell is going to contact us after a few days asking us to arrange using a pre paid service link.
I went to my case(online) and left a note saying I received the replacement and am testing it now.
Will wait a few days and if I don't have any issues with the replacement or if they didn't contact me before then I will ask them via a web note.
