P2418D, irritating Power Save Mode popups

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.

I'm sure I closely checked the DELL logo on the P2418D that I RMA'd a couple months ago.
The logo on that bezel was matte.
To be sure, I just asked about it on amazon.com.  Others there state their monitor's logo is matte.

But the new P2418D I just received, it has a chrome DELL logo.  Like a mirror.
Yikes.  It reflects every movement of my hands on the keyboard.

I see Dell recently found enough  money and engineering time  to modify their logo.
Instead of the firmware.

I think these will be my final thoughts about this P2418D.

There is a golden glow that travels with my view, no matter where I position myself.  It really bugs me.

The photos above are extremely exaggerated.  I put my smartphone camera in fluorescent white-balance mode to take them.  (or maybe that WB symbol means halogen lighting).  Yes, the screen is set to a cool temperature, but not blue like that.  OSD Red=95, Green=99, Blue=100.  The reason I set it cool is to reduce that objectionable traveling golden glow.

Edit.  I just changed it to OSD Red=94, Green=98, Blue=100.  Much less disagreeable.  Gosh this thing is touchy.

You can also see a hint of that golden glow in my previous post's logo picture.  (click it to view full-size).  Top-dead-center in the blue Windows Desktop.  That photo was taken in normal (auto) white-balance mode.

There is a fairly recent review on amazon.com complaining apparently about this very thing.

Edit again.  I've now taken the opposite approach, and warmed the screen instead.  OSD Red=80, Green=79, Blue=76.  This also serves to dim the screen.  The green glow is still present, maybe even more so.  But it now agrees more with the resulting warmth of the screen.  So at least, my eyes are no longer obsessing over it.

I just don't get it.  I have a 10 year old 16:10 monitor, 117 dpi, which is better than any of 5 brand monitors I've tested in these past two months.  I don't have any more time to waste on this, I need to move on.  I'm just going to keep this P2418D and forever be displeased with it.

This monitor is making me nauseous, browsing and text editing.

With white backgrounds, the top,right,bottom,left are warmer than the center of the screen.  The longer you gaze at it, the more you notice it.  Compared to the center, those outer zones each have separate golden coral hues.  You can't help but balk when you scroll text up through the top 25% warm zone.  The bottom's like that too.  And even in the center, depending on viewing distance, I keep seeing green splotchy haze around black text.

The really odd thing is, it seems like this monitor has some sort of dynamic contrast electronics that adjusts regions separately.  So, when I just bring up a full white screen, it doesn't seem that bad at all.  Yet, when I flip back to this very forum post I'm editing right here, right now, my eyes will not stop obsessing.  Ugh.

This quality is all that's in production.  We're not going to find a P2418D (or even U2518D) that's any better.  They're all coming off the conveyor belt with that yellow bottom-left LED and golden green glow.

I still have a few days left in the Dell return window.  I lost 2 weeks of it, exchanging that previous P2418D which had a permanent red line in the panel.  Take it or leave it.  That's all that can be said at this point.

What a drag.
