AW3423DW, does not wake from standby

I am currently using the 1.1.0.0 driver but I have tried both. Windows has never tried to install the older driver, I manually installed it to see if it would fix the issue. Plus I have no idea what the Dell driver download tries to install. When I run the exe, nothing changes in the properties screen so I don't really know if it's doing anything. It just stays as whatever driver I had installed at the time. I've also tried browsing to the folder the zip file created but there doesn't appear to be any actual driver there.

Like you mentioned, when the monitor wakes normally the rear lights and the power button go through several colors before turning purple (which is what I have it set to.) I have actually never once seen a popup saying it was going to do a pixel refresh, and I have confirmed in my settings that the auto warning message is set to on. The only way I know it's happening is when the power light turns green while the monitor screen is black. I have never tried doing a manual pixel refresh. I also set eco mode to off to see if that would alleviate the issue but it didn't.

I originally had the refresh rate set at 175hz, but have since changed it to 144hz to see if that would change anything but that did not. I can't imagine what refresh rate would have to do with anything, but hey, it doesn't hurt to try.

Being as I don't have any other issues (loud fan, stuck or dead pixels, scratched screen) I don't really want to give up my monitor in the chance I'll get one back that's worse off. Maybe I should try to reset to factory defaults and see if that does anything.

Easy questions first.  What driver are you using for the monitor.  I have 1.1.0.0 (3/14/2022) but Windows keeps trying to install 1.0.0.0.

I have never needed to plug or unplug my monitor as you seem to need.  I am in just about the same situation as you regarding the monitor.  Using the DP input @ 120 Hz, RTX 3090.

My monitor goes low power when the video display is lost.  The light blinks white.  When the computer wakes up the light goes through the color changes but is not doing a pixel refresh.  It returns to steady blue while on.

There are three configurations where I do the pixel refresh.  First, during the pop-up message I push the joystick and the monitor turns black and goes through the refresh and leaves the monitor off when finished.

I also put the computer to sleep or shut it down and about 2 minutes later the pixel refresh starts.  After the same 6-7 minutes, the monitor returns to standby with the blinking white light.

When the computer comes back up, the light goes through the multiple colors on the button.

Verify that the monitor is plugged into the machine.
Unplug the VGA cable.
Hold the 2nd and 4th buttons (counting from left to right). These are the + and < keys.
Unplug the power cord.
While holding the + and < keys, plug in the power cord and continue to hold the keys until there is a solid green light. (The light will be green for approximately only three seconds and then will turn orange.)
Plug in the VGA and attach the monitor again.

Hope this helps you out,
John

I agree it is definitely a strange issue. I can say I've tried different cables, both DP and HDMI, 2 different video cards, and 2 different OS' with a fresh install of each. The MSI monitor which is also connected has never once had this issue, and that has been connected for several years at this point. 

As you said it would be very unlucky to have 2 monitors having the same issue, but the 2 having the issue are both made by Dell. I will continue to troubleshoot on my end, as last night I uninstalled the Alienware Command Center (which for some reason was not a very easy process) as well as reset the monitor to factory defaults and have not had the issue occur again. I appreciate the feedback and can only hope this fixed the issue.

I had a similar issue with my last monitor, a Dell S3220DGF. That monitor also would go into sleep mode, but the backlight would stay on displaying a black screen turns back on.

While not only is your problem unusual, it's off-the-scale rare to have two separate monitors doing rare abnormal things.

Personally, I would be checking the computer and/or cables right about now.

You can also troubleshoot monitors by connecting them to a different (known working) computer and see where the problems follow.

Hey I am having the same issue Mine is about 2 months old was working amazingly then one day i came home from work turn on my PC and nothing. Ive done everything I unplug it I changed all the cables. the lights will turn on but i get no picture at all so I had to call dell and have them send me a replacement the screen just completely died out of no where

I am having the exact same issue: monitor is dark and nonresponsive, no input from the machine does anything, though the machine is on and working (and you can hear that it is in fact functional and accepting input as normal), and the monitor power button is lit --  sometimes white, sometimes a random color. The only way to get the monitor panel to come back on is to unplug the machine and plug it back in. Pressing and holding the power button or joystick do nothing.

Latest drivers; display port to the PC; monitor power plugged direct into the wall.

This happens a few times a day to me now. I'm going to have to RMA the monitor, which is too bad since it's a nice panel.

My brother in law has the same problem with his AW3420DW.
The Monitor is not tuning back on after the pc (fAlienware Aurora R13  iirc) wakes from hybernate.
Connected via DP to a Radeon 6900 XT iirc.

My brother in law is really upset about it since he has little time to fix such issues because he works a lot an thought he could spent some quality time by buying an overly expensive AW... but AW  has been a disabpointment.

This is happening to me, too. I have been using the monitor since April/May.

My monitor will randomly not wake up from sleep and remain completely unresponsive until I cut the power to it and start it up again. No amount or length of button pushing on the monitor results in any response. Can't open monitor control display; nothing. The power LED will flash--usually white, but occasionally a different color such as teal or pink/purple.

Same thing here, I'm worried about what this means for the future of the panel.

It started maybe a couple weeks ago and before that was completely fine. I can think of 2 things that may have changed since then:
- The panel automatically ran its first panel refresh
- A Windows 11 update

But that's all I can think of. Nothing else changed. If there is no fix I might have to RMA for a new one...

I wish I could tell you all I figured out the problem and fixed it but I haven't. I do believe it is tied to the pixel refresh. The only workaround I've found that seems to work is I shut the monitor off when I walk away instead of letting it go into sleep mode. This seems to make it happen with less frequency for sure. Since I am now out of the window where I will get a new monitor if I send it in for replacement I will keep it as I do think it looks great and I have no other issues. If I find anything else I will update the thread.

I would have gotten involved in this thread earlier but using colors which are not the default settings can get confusing when trying to describe a problem.

But one observation, with the computer and monitor on, after a period, the monitor will go in the low power mode with a pulsing white light.  If you move the mouse or otherwise wake it up, it may take a couple of seconds for it to come back and the light goes through the colors and ends up back on teal.

It appears your problems are related to the low power mode black screens.

Is the AWCC involved and being used to control the monitor?

Have you tried changing the power source for the monitor?

I see both of you state, holding the power button for a few seconds, does not turn the monitor off.

My system is on Win 11 with all the recent updates.  It is run with a DP connection from an Nvidia RTX 3090.

Thanks for taking the time to reply. Perhaps you think by us mentioning colors such as pink or teal are the colors we chose, but that is not the case. Like you said, as the monitor wakes up, the back panel lights and the power light cycle through several colors, regardless of what settings you may have for your panel lights. Of those colors, there is pink and teal. What's happening is as the panel wakes, it locks up, and the power light gets stuck on whatever color it happened to be on as the monitor was waking. Sometimes it locks before the lights turn on so it will be locked with no light on. From this point on the monitor is completely unresponsive. The only way to get it to work again is to pull the plug, wait a bit or hold the power button down, and plug it back in.

I know in my instance I have tried with and without the AWCC, new drivers, old drivers, HDMI, DP, Win 10, Win 11 and a myriad of video card drivers. I have tried 2 different electric circuits in my house. At this point I will just live with it until it dies. At that point hopefully its still under warranty. If its not, I'll get a new monitor.

I have been thinking about this and although you have tried these things, I will just list some possibilities.

First, turn the monitor off and unplug it overnight.

Second, verify the security of the power connection on the back of the monitor.

Since the system locks up when coming out of standby, have you tried turning it off, then turning it back on and waking it?   Since you can't wait until it actually locks up, maybe turning it off first would reset it so it would not lock up when waking up.

I do agree, if you can't find anything then a problem with some component may be the cause.

As info, I do not run AWCC on the system and I do not have a Dell mouse or Keyboard attached.  Also, only one monitor and I normally allow the pixel refresh to work using the menu button, when the message shows up.

Hopefully, something will show up that explains the situation.

I meant to reply to Saltgrass regarding the lock up a while ago but got busy and forgot to. Like Guyjin37 said, it's not the system that locks, it's definitely the monitor. My  MSI monitor that is plugged into the same video card powers on and works as usual,  but windows does not recognize the Alienware monitor. Once I unplug and plug it back in, windows notifies me a new gsync display has been detected, and the monitor turns on.

I'm just going to continue using it until it doesn't turn on anymore, then I'll rma it. Hopefully by then there will be a new firmware that resolves the issue.
