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.
Create a new admin user account in System Preferences Accounts pane
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8235.html
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.

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.

Monitor enters power save mode on start up

PC keeps crashing in game, after it crashes it shows the message DVI power save mode on my monitor. Sometimes it even crashes on boot.
It all started when i tried to update my bios with live update(yes I know wrong choice, after I did this is read all the wrong things about live update on google)
So i flashed my bios with an usb drive to 1.8, but it's still crashing
Setup:
MOBO: Msi Z87-g45
CPU: Intel I7-4770K
GPU: EVGA GeForce GTX 770 4GB Dual SC w/ ACX Cooler
memory: Corsair Vengeance LP CML8GX3M2A1600C9 4x4gb
PSU: corsair HX750
So I tried everything I could read about this problem on google, I even rma'ed my gpu and it still crashes.
Anyone that can help me? or is the board bricked and should I rma it?

Nope, didn't do an oc, sometimes after restarting several times i can run something. Like a game but after some time it freezes and gives a gray screen with 'dvi power saving mode' after that nothing works, no caps/numlock.
I was thinking it was the gpu, so i rma'ed it but when i had it back, it gave the same thing.
I thing it's the board, pci slots or something
Edit: it doesn't freeze with integrated gpu so it must be something with the slots? Evga tested my gpu in another system.

"Entering Power Save Mode"

Hi guys. I have an HP desktop and a Dell SR2320L Monitor. It was working fine until a few months back. I was out of town, came back last week and now every time I start my PC it just stays there "Entering Power Save Mode". I tried almost everything researching a solution for the problem but just won't work. Is there a way to check if the cable is the problem or the monitor or anything else? Any help will be much appreciated. Thank you.

Hi Ankur,
Monitor may enter in power saving mode when it does not get the enough power for its operations. If monitor is the cause, you may try to re-seat the monitor cable and ensure the connections are secure. You may also try to swap the ends of cable and check if the issue persists. Another step you may try is to use a good known cable and see if the issue persists. If it does, as a last resort you may try to reset monitor to factory defaults. For more information on this, you may refer to manual of monitor: http://bit.ly/10ErgRX
Another possible cause of the same issue might be video drivers of your computer. You might need to uninstall and re-install the video drivers and may check the power options in operating system. You might need to check the HP website for download and installation of video drivers (relevant to the system model).
Please share the findings.

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.

Can I read Windows OS properties in LabVIEW (ex: Is monitor in power save mode?)

Is it possible to read any properties from windows OS. I would like my code to know if the monitor is in power save mode or not.
I am using a touch panel and after the screen goes blank (power save mode), I don't want the user to accidentally push the wrong button (since he cannot see them). The user has to touch the screen once to waken it up. As far as I know there is no way for me to disable the touch screen while in power save mode so I wanted to try and disable the buttons when the screen is in power save mode.
Thanks,
Javier

Look here. At a bare minimum, it loks like you need DevicePowerEnumDevices and GetDevicePowerState.

LG Monitor entering power saving mode despite thunderbolt connection

I have a full boat 2013 rMBP connected to a LG 34UM95 though thunderbolt and it has been working flawlessly for about 4 months. One connection from the laptop to the monitor and my external drives connected to the monitor. It has been great.
Until today
For whatever reason, my rMBP isn't detecting the monitor. It isn't showing up in preference or apple menu. I know the thunderbolt port is working as the drives are still visible that are connected to the monitor, but I can't run dual display or clamshell mode. I have rebooted several times, both the monitor and laptop.
This *****.
Any suggestions?
The searching I have done has revealed some NVIDIA card issues causing some challenges for others, so I hope it isn't anything like that.

Hey Cult Hero,
Thanks for the question. Based on what you stated, it seems like you are having trouble with an external display. I would recommend that you read this article, it may be able to help you isolate or resolve the issue.
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
No video or no signal, image distortion, "snow," or flickering
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thanks for using Apple Support Communities.

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).

How do I get out of power save mode?

Just recently my the monitor connected to my Mac Pro has had problems waking from sleep. It warns that I am entering Power Save Mode, and restarts do nothing.

Try doing smc and pram resets.

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.

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)?

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.

Lenovo G500s laptop monitor doesnt recover from power saver mode

Hii everybody,
i have been using this G500s laptop for an year or so...recently my laptop has started showing troubles with the screen saver or the power saver that comes by if i dont use my laptop for few mins..! when i dont use my laptop it goes to power saver mode and the monitor doesn not return back to power when i try to resume my work...!!! and interestingly i could hear the cooling fan running at high speeds and my laptop heating up... and it sounds like my whole laptop is working other than my monitor..!! my monitor is just a black screen..... and my system has began to slow down nowadays.. desperately need help on this..!! it has started becoming frequent

hi Murali993,
Welcome to the Forums.
Just to verify, when the machine goes into Power Saver Mode (Standby / Sleep), can you check if the power button is blinking (this is an indication that the machine successfully entered Sleep State).
If the power button is just a solid light and it's not blinking then the machine is likely not entering Sleep. In this case, consider doing the following:
1. Turn off Hybrid Sleep under Control Panel (Icon Views) > Power Options
- Link to picture
2. Set the computer's power setting to HIgh Performance and disable the HDD's power management settings (see this guide)
3. If you have external devices plugged-in (eg. Flashdrives), unplug them then perform a clean boot (this procedure temporarily disables background services/apps that are running in the background that's possibly hanging up the system as these are normally terminated before the machine goes to sleep).
Let me know how it goes.
Regards

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?

Monitor won't enter power save after playing You Tube videos...

Hi
An issue has developed on my system in the last couple of months for which, after having done a lot of research and testing, a solution has not been found. After playing a video in You Tube, my monitor won't go into power save mode after the prescribed time. It tries to go off for a second and the screen goes blank but then comes straight on again. This happens after playing the You Tube videos in Firefox, Google Chrome and Internet Explorer. I am running Windows XP Professional and I have the latest version of Adobe Flashplayer installed, the latest graphics card drivers, the latest version of direct x 9.0c.
To clear this error, I have to go into my XP power schemes settings and change it to another power scheme and then change it back to my default power scheme. However, as soon as I play another you tube video the same problem re-occurs.
I have tried turning off hardware acceleration but this makes no difference. My graphics card is a Gigabyte gv-nx86t512h: http://uk.gigabyte.com/products/product-page.aspx?pid=2604#ov
This never used to happen until recently. It seems that there is something with the Flashplayer that is not compatible with Firefox, Chrome, Internet Explorer etc.
Any ideas as to what may be causing this and what can be done to overcome it would be greatly appreciated as it is a real nuisance.
Many thanks.
D

thanks for your suggestions.
i found the solution/workaround from somone else on the adobe forums:
Go to control panel, display, screen saver, choose a random screen saver, set a long time (i.e. 60 min, but always longer than your monitor shut off time), then select no screen saver, and save! Simple as that…
