AW3423DWF Pixel Maintenance

[SpellowHouse]

I suddenly noticed, or perhaps "has slowly dawned on me" that my AW4323DWF has stopped asking for pixel maintenance, except when it powers down or up. The 4 hour messages have ceased.
Has this happened to anyone else?
I have checked the configuration, and in fact today I have reset the monitor to factory default and am 2 hours in to a final check before I return the monitor.

I checked the configuration and it's enabled.
Then I went back to M3B106 and it started working again.
I guess that what I should have tried is resetting the monitor while M3B107 was still in there, just to see if that was all it needed.

I set mine to not display the message when it’s needed as it just became annoying.

It does the maintenance when the screen is on standby, without ever asking

I dare not do that, alas, or the maintenance would only happen once a day instead of three times!
I must admit, the message is annoying, but better that than my monitor dying.
