P2418D, irritating Power Save Mode popups

Jump to solution

Screen-plus-Keyboard.jpg

 

I just purchased a P2418D monitor from Dell store.

It does a really irritating thing.  Every time my computer is idle, and Windows Power Mgmt puts the monitor to sleep, here's the sequence of events:

  1. the monitor backlight turns off  (good)
  2. a few seconds later, the backlight turns back on  (bad)
  3. a diagnostic popup appears saying scanning for signal  (bad)
  4. another follows saying no signal  (bad)
  5. then a third appears saying it's going to Power-Save mode  (duh)
  6. the power-button LED begins flashing  (which is disabled in OSD menu option)  (grrr)
  7. the backlight turns back off, again and finally.

Sheesh.  This is so irritating.

As a comparison, I also have a pretty new HP monitor.  It doesn't do this nonsense.  When Windows puts it to sleep, it goes black.  End of story.  And the power-button LED stays off.

Dell Tech Support tells me my monitor is faulty.  I'm in the process of exchanging it.  But from what I just read in another thread here, the power-button LED issue is by design.  It just turns back on and flashes, despite the OSD setting to disable it.  So I expect the whole annoying sequence above is by design too.

Any advice before I end up RMAing this monitor for refund?

The "Menu- Personalize- Power Button LED" off state ONLY applies if the PC is on.

 

If the PC is on/active, open the Menu- Personalize- Power Button LED. Change to off During Active, page 42. The Power Button LED should turn off.

If the PC is off/inactive, the only way the P2418D power button LED will turn off is when you press the power button to actually turn the P2418D off. Otherwise it will blink, page 34.

 

In your scenario, the PC is on/active and the operating system tries to sleep the P2418D. The User's Guide does not spell out how the P2418D will act in that hybrid state.

 

On all of my Dell monitors (UP3216Q, U3415W, U3415W, D3218HN), I do not allow Microsoft to control them. When not in use, I simply turn them off via the monitor power button.

On page 41 of the user manual, it says

Power Button LED
Allows you to set the power LED indicator On or Off when the monitor is active to save energy.

So, when the monitor is inactive aka Power Save Mode, it is Dell's intent that we should not save energy.

Here it is, 2019.  I just purchased a P2418D.  It has this exact same bug. I guess Dell still does not have enough  money and engineering time  to fix this bug. I will RMA this monitor for refund, and wait until they do.

Chris, I'm sure you recognize the copy+paste above.  I posted it in the 2017 U2718Q thread just prior to starting this new thread.  That thread got locked within minutes of my posting.

Regarding the InfinityEdge sticky thread.

It was stated there that the shadow smudge effect occurs only when the Windows TaskBar is absent.  That is not accurate.  It appears whenever viewing the monitor at a sharp angle.

But this is a separate issue.

 

For me, the edge shadows are not a show-stopper issue.

The obtrusive popups and flashing LED are.

Searching through this forum, I've found a number of inquiries about these "by design" standby bugs.

Here's another complaint about the power-button LED, from just a couple weeks ago.

I tried to +1 kudos the final post, but couldn't.  It's locked.
Maybe I can ask you to vote it up for me please, Chris.

Anyway, I'd like to share my solution with you.  I shipped the monitor back for refund.
