Dell monitors go into power save cycle

I got 2 brand new Dell P2412H monitors to use as a dual display. However when the computer puts the display to sleep they go into a "Entering Power Save Mode" cycle and the display never shuts off it stays blue and continues to do that. This happens with either display even in single monitor setup. I have the problem on my old Powermac G5 and now on my new apple mac mini. What is happening?
I have read about similar problems here but they were not solved:

And this guy even made a youtube video of the same problem but different monitors:

I've tried a factory reset on the monitors. My monitors sleep settings are fine and they wake up from being asleep perfectly. As of this morning my little trick of unplugging them and swapping connections has stopped working. Now, when I swap cables the video card automatically assigns the primary video output to one of the monitors and keeps the other one asleep. very strange. So when I unplug the mini video adaptor from the dvi cord and then place that same cord in the native dvi output on the video card the card automatically reassigns the primary video output to that channel. So no matter how much witching I do I always end up with the system acting like I have a stretched desktop but with only the left display working while the right one is asleep. It's time to give apple support a call.

Force External Dell Display Into Power Save Mode

How do I set up my MacBook Pro to send a video signal to my external Dell monitor to tell it to go into Power Save Mode when the MacBook Pro goes to "Sleep" (after the Preference set default of 14 minutes)?

New LG Monitor Screen Image Keeps Shifting a few pixels left and right / goes into power save mode

I just purchased a new LG Computer Monitor from Best Buy today and hooked it up to my PowerMac computer. Shortly after setting it up, the entire screen image started sporadically shifting left and right a few pixels. And then, at seemingly random times, it'll shut itself down, going into power save mode. I checked the cables to make sure they were secure and they seem to be. Could there be some sort of interference that's causing it? Or would it be the graphics card? My computer is only a couple years old. Please help!

Do you have another computer you can plug the monitor into to test?

Dell 2407WFP MacBook Pro Power-Save

I've just picked up a Late 2011 MacBook Pro 13" and attempted to connect it to my Dell 2407WFP monitor, via DVI with a genuine Mini DisplayPort to DVI connector.
The monitor is working well as an extended desktop, however, when the system attempts to put the monitor(s) to sleep, the Dell gets stuck in a loop. It shows the "going into power-save mode" repeatedly, but never gets there.
The monitor does seem to correctly go into power-save when the system is shut-down.
I've read some similar threads, but none referring to this model.
Any help would be much appreciated

My Dell 2407wfp works fine with VGA, but I couldn't get it to work with DVI. I narrowed the problem down to a faulty MiniDisplay Port to DVI adapter. The Dynex brand one was not working properly and kept causing the monitor to attempt to enter power save mode. (The Dynex adapter would get warm even when no cable was plugged into it!) I bought a genuine Apple adapter at Best Buy and now it works fine. If that doesn't help try resetting PRAM (command-option-P-R on start up).

Macbook pro goes into power save mode with dell sp2208wfp monitor.

I have a macbook pro and am trying to connect it to a dell sp2208wfp monitor, I am using a hdmi cord and it goes straight to power save mode. My mac works on my roommates monitor and his PC works on my monitor but my mac doesn't work on my monitor. I've read the other forums and have found nothing. One guy suggested plugging the mac into a power source still nothing, any solutions before I try and sell this thing on craigslist?

Had the same issue a few months ago when I tried connecting to external monitor, it is only possible to run external displays from a Macbook Pro while the power cable is attached, if you try and connect to external display without having the charger attached the external display will flash your desk top for a second and then your Macbook Pro will go to sleep. Hence connect your charger every time you wish to connect to external display, its not a problem with your Macbook Pro, it's just the way of Apple. Hope that helps.

Dell 2405FPW stuck in Power Save with MacMini (PPC w/ATI Raedon 9200)

I'm wondering if anyone is having any problems with their Dell 2xxxFPW monitors (specifically the 2405FPW) getting stuck in Power Save mode. This is a known problem with some Dell monitors. More details can be found here:
http://forums.us.dell.com/supportforums/board/message?board.id=dim_monitor&messa ge.id=33721
This problem only presented itself when I began to use my MacMini on my 2405FPW. The FAQ clearly states certain problem 'cards', with a generic 'ATI' reference. They recommend upgrading to the latest drivers as this has to be done in order to avoid the monitor getting stuck in this mode again. Needless to say, I ran the fix and it did resolve the issue, but two weeks later I'm experiencing the same problem. I never had this problem when I used my monitor with my Windows desktop.
My question is, is someone at Apple aware of this and is there any type of driver update/fix out there? I'm assuming anything would've already been pushed down via Software Update, and I grabbed ATI's latest Display drivers and apps on their website to no avail. (There's a ROM update, but they specifically mention this does not apply to OEM's).
I might just have to move my Mini to a VGA connection, which I really don't want to do...
MacMini PPC Mac OS X (10.4.6)

Manifisation is random, and I can't link any specific behaviour to the event. I'll be in the middle of reading an email or browsing and the monitor will flicker and just have a 'blank' screen. I can either turn it off/on or wait until the monitor goes into standby and move the mouse. Unfortunatelly its gotten to the point where the monitor just goes 'blank' every minute.
I can run the known Dell fix (a third time), but if something on the Mini is causing this behaviour its pointless to keep trying.
I'm tempted to try using my gf's Dual Core Mini (go figure, she gets the new one and I inherit hers) or just swap her 20" Cinema Display for my Dell 2405FPW

External Monitor keeps entering "power save"

I just bought the new late '08 MBP and have it connected to an external monitor (Dell 24") using the mini DVI to VGA adapter. I used the same monitor with my earlier model MBP, with no problems. But with the new '08 MBP, the monitor constantly goes into sleep mode and I have to shake the mouse or hit the command key to wake it up.
It could possibly be because I am using Mini DVI to VGA, rather than the DVI connector.
Any suggestions how to fix?

I am seeing a similar issue. I have a late 2008 Mac Book Pro with a 22" Dell Crystal monitor. The montor is connected to my MBP via an Apple Mini Display port to DVI adaptor. When I set powersave and sleep on the MBP to on (e.g. 60mins), the monitor goes into powersave mode but the MBP never goes to sleep. Subsequently when I try to deactivate the monitor powersave by using the bluettoth mouse/keyboard, the monitor does not respond. When I turn the monitor off and then on, it displays a message stating that its going back into powersave mode, and then turns off accordingly.
To resolve I need to unplug my monitor, open the lid of my MBP (display is still off but keyboard is lit), shutdown the MBP by depressing the on/off button, power on the MBP by briefly pressing the on button, put the MBP into sleep mode manually via menu, close th lid, plug the monitor back into the mini display port, and then use the bluetooth keyboard/mourse to wake the MBP from sleep mode.

Monitor Goes into 'Power Saving Mode' HDMI

I have an LG monitor (IPS237-BN) which always goes into 'Power Saving Mode' when I connect my MacBook Air to it via a Thunderbolt-HDMI connection.
Sometimes it actually connects and I can mirror my displays (or count it as another), most of the time it doesn't. I have used different cables etc. I cannot install the driver because I do not have a CD drive.
Any help is appreciated, thanks!

Hi,
Update the the video driver from the NVIDIA web site.
Your PC bios should be 5.29 or higher so that is something to check.

Dell U2414H Waking from Power Save Mode

Hi,
I recently purchased the Dell U2414H 24" monitor and have encountered some issues relating to my MacBook Air Mid-2013. When the monitor is connected to the notebook and the notebook is placed into sleep mode, the monitor flashed a note saying "Entering Power Saving Mode" then proceeds to Power Saving Mode. Yet when I come back an hour or two later, the monitor is continually cycling through this process. It will come on, display this message, proceed to Power Saving Mode and then repeat. Below I have embedded a video displaying the problem. I have the notebook connected using the included Mini-DP to DP cable connected to the ThunderBolt port of my computer. I'm running the notebook on OSX Mavericks 10.9.4. I have tried disconnecting the cable at both ends, restarting the computer and disconnecting power from the monitor.
Hope you can help.

How about if you open System Preferences Displays pane Display tab... Click on +Gather Windows+ on the display that is working. Then try adjusting things like resolution and +color depth+ on the non-working display to see if that has any effect.
Have you tried disconnecting the power cord on the display for a few minutes and reconnecting it? Does the display have an on-screen menu, and a command to reset the settings on the display to default?
A few more tests, if it still does not work.
Create a new admin user account in System Preferences Accounts pane

Log out and log in to the new account. In the new account, does the display work or not work properly? If it works in the new account, that would indicate some problem in your regular user account.
Also try starting up from your Mac OS X installation disc. Does the display work when you are starting up from a different system? If so, that would indicate some problem in your current installed system.

My 4500 all in one goes into power save and will not come out of it without pulling the power plug.

I have tried hitting the power button short and long, pushing every button, but it seems the only way out is pulling the power plug.
Thanks for any help.

HI
This is a known issue and HP is working on Firmware to fix this issue. This will be released soon.
So please use the workaround for the time being if the printer goes to power saving mode.

Stopwatch - doesn't freeze, but goes into "power save"

What am I missing? I have started using my iPod's stopwatch to time my daily walks -- and, lately, after walking a bit, I look down and the screen is black. I press a key to bring it back to life, and the stopwatch has STOPPED. What good is that? I read in the manual that it is SUPPOSED to do that if you go off the stopwatch screen (e.g., back to the menu, or something) and music IS NOT PLAYING. But I'm staying on the stop watch with music not playing. Anyone?

Sorry -- not sure why I'd want to put it to sleep when it's already "sleeping?" The screen goes black -- even though I've not left the Stopwatch. Sometimes it doesn't -- the other day, I walked for 20 minutes and it stayed on, the entire time. Today, though the battery APPEARS to be fully charged, it went black on me repeatedly until I just gave up.
Not sure I understand your suggestion...!

Connecting my MacBook Pro to Dell Monitor

Hi, I have a Dell E228WFP 24 inch monitor and I have connected it to my MacBook Pro (October 2013, Non-retina, 13 inch) with a Mini DisplayPort to DVI adapter, and another adapter off eBay, which plugs into the VGA cable that is in the back of the Dell monitor. When I turn the monitor on, the screen remians black, then the monitor goes into power save mode. The Mac can find the monitor, and the Mac says the monitor is working perfectly.
The monitor goes into power save no matter if I put it on Auto Detect or Digital imput, or Analog input.
Please help!

Searching on Amazon, I find the monitor has HDMI. a Mini-Displayport to HDMI adapter from the Apple Store is a much better choice than any VGA adapter. Also your machine will support audio over HDMI if there is audio on the monitor. If not, that's immaterial for that monitor:
http://www.amazon.com/Dell-E228WFP-Widescreen-1680x1050-resolution/dp/B001BKR5D8
Anyway, HDMI carries the full digital signal. So does DVI. I for one prefer HDMI since it is less likely to fail connecting.

Dell 2407 Monitor entering power save mode immediately!!! :(

I have a Dell 24" 2407 Monitor hooked up to my 24" iMac (white 2.16GHz core 2 duo). Problem free for the past couple of years, until recently, my monitor keeps going into power save (when the iMac screen is active.
It's connected via DVI, and the funny thing is, is that the iMac still detects the monitor, but it's in power save mode.
I plugged the monitor into the MacBook Pro and it worked fine. So I'm guessing it's either the Mini DVI to DVI converter is stuffed OR something is wrong with my iMac. I'll try another dvi cable, otherwise will have to go to shudder VGA until I get a new Mini DVI to DVI converter. Unless anyone else has an idea as to what's going on?

How about if you open System Preferences Displays pane Display tab... Click on +Gather Windows+ on the display that is working. Then try adjusting things like resolution and +color depth+ on the non-working display to see if that has any effect.
Have you tried disconnecting the power cord on the display for a few minutes and reconnecting it? Does the display have an on-screen menu, and a command to reset the settings on the display to default?
A few more tests, if it still does not work.

U2312HM and second monitor = Entering Power Save Mode

So, my monitor has not been able to turn on for about a week now. It shows that it's getting power, but after 3 seconds I get the message that it is going into power save mode. I am able to press some buttons on the monitor and a message pops up that there is no signal and to try typing or moving the mouse which doesn't work. I've attempted to change the input source which only leads to "No DisplayPort Cable - The display will go into Power Save Mode in 5 minutes.". I have tried a separate monitor which is extremely less powerful and I get the same message that it's entering power save mode. Could this be a fried video card or what's happening here?

Thanks for the reply Chris. I do have both DVI and VGA out ports and I will be testing that today. Not sure if this has anything to do with my issue or not but I might as well mention it. I have 4 2 GB ram sticks which came with my pc. I purchased two new 2 gb ram sticks due to some memory issues I was having. The problem is, the two new ram sticks I had were not the correct size but I attempted to use them anyway. Now prior to inserting these new ram sticks I cleaned my pc using air duster and a light suction vacuum cleaner, not sure if I got all of the dust. Once I found that the ram sticks were not the right size I then reinserted my older ram sticks and this is when the monitor issue occurred. A couple people had mentioned that this sounds like a bad video card, but could inserting wrong ram sticks affect the motherboard and in turn mess with the videocard?
Also, roughly 3 weeks prior to the monitor issue, the lights on the side of my case are generally dark blue (but can not confirm if this is normal as I rarely pay attention to it.) The only reason I bring this up is because the lights began to turn red, then a sortof clear light color progressively throughout the next couple of weeks, eventually not turning on at all. Again, I've never really noticed the lights on my pc to begin with so this could not mean a thing.
