External display sleep

I have an LG l196wrtq 19 inch monitor hooked up to my macbook using the mini-dvi->vga adapter. The monitor seems to not be able to detect when i put my macbook to sleep and stays on with a message saying" check signal cable". I've called LG about it and they simply told me that my mac is not sending a signal to the monitor telling it to go into power save mod aka sleep. My question basically is is there is a way to have the computer send a signal to the monitor so it could go into power save mode?

You should do all the usual first steps like running Disk Utility and resetting the PRAM.
If those don't fix the problem, you should start up from the Mac OS X Installation disk and do an "Archive and Install." Click on the Options button on the Installer screen to select this option. This will retain your user data and settings, and give you a fresh System. Then immediately run Software Update to get your system up-to-date.
If you choose to do this, it would be a good idea to select Disk Utility from the Installer's Utilities menu, and run the Repair Disk routine before doing the Archive and Install. And it's always a good idea to back up your valuable user data.
I did an Archive and Install when 10.5.2 came out. I wasn't having any problems, but I knew 10.5.2 was a huge update. My existing Leopard installation was installed on top of my previous Tiger installation. I wanted my Mac to have a fresh start. Everything is working great.

HT3131 Macbook pro + external display sleeps when lid closed and 'clicking' noise

Hi all, new mid-2012 macbook pro non-retina user, I have an PC external display with Microsoft USB wired keyboard and mouse pair (the keyboard and mouse are wireless but connected via a USB desktop receiver) but even when all connected up, shutting the mac lid always turns off external display too and no amount of pressing keys or mouse clicking wakes up the display again. External display only wakes up when I open the lid again. There's also a clicking noise from the mac every time I close the lid with external display connected. Any ideas? I've tried a number of things, wondering possibly if my cheapo (non-Apple) VGA external display to Minidisplayport adaptor is the culprit? Also, everytime I connect the display I have to go to display settings to get it to recognise the external display. I haven't installed any software for the USB mouse and keyboard , the macbook recognises it ok.

Hi Itsfixed,
It sounds like you are having issues running your MacBook Pro in closed clamshell mode (computer closed but awake, connected to an external display). If possible, you may want to see if it behaves as expected when connected to a wired USB keyboard and mouse as outlined in the first section of the article; wireless USB (non-Bluetooth) keyboards may not be recognized by the system the same way for the purposes of running with the display closed.

How do I put an external display to sleep when I am using my MacBook Air for presentation?

How do I put an external display to sleep when I am using my MacBook Air for presentation? I do not want to go to the projector just to turn it off and turn on again after a while? Is there a keyboard shortcut for that?

I want to be able to sleep the external display and at the same time do things in the MacBook.( This feature is useful for me so that I can prepare some things and so that my audience will not see what I am about to show them.)
Is there a feature for Mountain Lion?

Mid 2010 Macbook Pro sleep and external display problem

I recently upgraded to the new 2010 15 inch core i7 Macbook Pro. The problem i have is that it will not detect an external display (23inch Cinema) after waking from sleep. This happens after using the display to extend the desktop and also when using the Macbook in closed mode.
I've managed to get it to detect the display only after either restarting the Macbook completely or by going into energy saver and switching to dedicated graphics then going back to detect display.
It seems that when on integrated graphics it doesn't register that an external display is connected. If i leave a program open and running that causes the dedicated graphics to kick in then it works ok. If i close all programs, shut the macbook pros lid, computer sleeps and external display shuts off. If i click the mouse to wake with lid closed, apple logo lights, machine starts up few seconds later macbook returns to sleep. If i open the screen the machine wakes as normal but the external monitor doesn't.
Any help is much appreciated as its starting to frustrate me now...
Many thanks
oh and im running OSX 10.6.3

I thought it was intermittent to begin with until i started looking into it. By leaving programs open, like aperture, before i put the machine to sleep it appears to wake the external monitor up without a problem. If i shut all programs or leave basic things open like safari and mail which don't require the dedicated graphics, then upon wake it wont register an external screen is connected.
Manually detecting displays in settings doesn't work.
Disconnecting and reconnecting mini display port doesn't work.
Turning off power to cinema display and powering back up doesn't work.
To get the display going again its either 1) turn off macbook pro and re-boot or 2) re-start the machine then the display is automatically recognised. Or 3) launch a programme that kicks in dedicated graphics then manually go in and detect displays again..... like magic the display then springs to life.
No ideas anyone??

External display resolution changes after returning from display sleep

I often use an external display as a second screen with my Macbook Pro (OS X 10.8.2) However, when I return to the computer after the display has gone to sleep, the external display resolution changes when the display reappears. Then I have to go into System Preferences > Display and "Detect Displays" in order to return the external display to the proper resolution.
Does anybody know of a way for me to avoid having to do this every time my display sleeps?
Thank you,
Adam

I have the exact same problem.
I found the key combination ⌘ alt F2 also restores the proper resolution on both displays, however it's still a bit annoying

Mac OS 10.4.3 Sleep, Powerbook G4, Airport, External Display Problems

I am running Mac OS 10.4.3 on my G4 Powerbook, system spec as follows
Machine Model: PowerBook5,6
CPU Type: PowerPC G4 (1.2)
Number Of CPUs: 1
CPU Speed: 1.67 GHz
L2 Cache (per CPU): 512 KB
Memory: 1 GB
Bus Speed: 167 MHz
Boot ROM Version: 4.9.1f1
Serial Number: XXXXXXXXXX
Sudden Motion Sensor:
State: Enabled
Version: 1.0
When the Powerbook is woken from sleep mode the airport crashes when using an external display. I have no idea why this is, but it seems from other threads, that the external display and airport are closely tied together, and I have also read that there are others who are experiencing some problems with the Airport. When this happens, I have to hard boot the machine as I can't forcequit or shut down the system from the menubar (this crashes too)
I have the following installed for my airport
2005-07-27 22:23:42 +1000: Installed "AirPort" (4.2
2005-11-12 12:00:12 +1100: Installed "AirPort Update 2005-001" (1.0)
Wireless Card Type: AirPort Extreme
Wireless Card Locale: Worldwide
Wireless Card Firmware Version: 404.2 (3.90.34.0.p16)
I am using an Apple 23" Cinema HD Display with the Apple ADC-DVI converter(previous model)
Can anyone help me with this problem?
Thanks

I don't think the DVD is damaged since it worked fine on my old G4 desktop.
The reason I'm trying to reinstall OS 10.4 is because I have received the computer from a family member with all his files and data in it. I want to get rid of it all and start from scratch for my personal use - if possible. If not, I could settle for less.
I want to explain few issues if that helps. I first tried installing Mac OS 10.3 to my Powerbook running Mac OS 10.4.3. I put OS 10.3 CD, started computer with C key held down, and all that came up was gray screen with 1 inch black line to the left of the Apple logo, and remained there - never making it to the blue screen. I shut of the computer, took the Mac OS 10.3 out of the Powerbook, restarted without the CD, and the computer was back to the desktop.
Then I tried installing 10.4, which goes past the gray screen, and gets stuck in the blue screen. I ejected the 10.4 DVD, and computer was back to normal (to the desktop)
It sounds like you inserted the wrong or a damaged DVD and neither the installation nor erasure took place. In that case, let's get started again on the right foot.
Tell me why you want to erase your hard drive? Were you experiencing some technical issue, and if so what? Let's troubleshoot that situation with the least harmful method.

Not detecting external display after waking up MBP from sleep mode

I am a recent owner of a MBP and enjoying it. However, one problem that I can't seem to find a solution to is the external display problem after sleep mode.
When I first boot up the Mac and plug in my Dell external monitor via the mini adapter, there is no problem with detection or display. However, every time I put the MBP in sleep mode and then wake it up again, the external monitor does not "wake" up and my MBP only displays my normal screen on the Mac.
I tried to 'Detect Displays' to no avail and the only solution is unplugging the mini connection and plugging it back into the MBP for the MBP to re-detect the external monitor.
Although this is a quick fix in itself, I do not want to wear out the mini port by doing this every timeI come out of sleep mode. Any solutions so that the external monitor will detect the MBP waking up from sleep and display properly? Thanks!

And same problem here.
Using a MBP 2.66 i7 with a Dell 3008WFP that's connected to the MBP through DisplayPort. It works some of the time but once in a while (only been using the new MBP for a couple of days now) the monitor won't come out of sleep mode. Turning it off/on causes OS X to completely ignore the monitor. I was able to get this setup to work again by pressing 'Detect Displays' in the System Preferences pane but most of the times that doesn't help. The only sure way to get the monitor working again is by booting into Windows through Bootcamp, Windows is able to use the monitor, if I reboot after that OS X sees the monitor again.
Also saw a magenta line/stripe on the left side of my monitor and the monitor sometimes makes a buzzing sound when connected to the MBP through DisplayPort. That's what you get by using bleeding edge tech I guess :\ Only alternative is buying the mini-DP to dual-DVI connector but paying $99 just to be able to use an external monitor is rather insane. Besides that lots of users are having problems with this adapter.

External Display doesn't wake from display sleep

My display is set to sleep after an idle period (computer itself set to not sleep), when I return to the computer and wake the displays the external display most of the time does not "wake" or come back with picture. I need to disconnect the adapter and plug it in again.
Anyone else experiencing this?

Guys, please read THIS thread:
http://discussions.apple.com/thread.jspa?threadID=1760586&tstart=0
EVERYONE is experiencing this bug if you're using your new MacBook Pro with an external display. In the thread above, I detail how to fix it without having to unplug the DisplayPort adapter.
The symptoms you're experiencing are:
1.) Bizarre interference all over the external display when either a) waking your notebook from sleep, or b) turning screen on if the screen is set to turn off after x minutes.
2.) External display not actually turning on at all after either a) waking your notebook from sleep, or b) turning screen on if the screen is set to turn off after x minutes.
The fix is listed in the above thread. It's only a temporary workaround, and Apple REALLY needs to address this issue ASAP.

Display issue coming out of sleep (w/ external display)

Hey everyone,
I've a MacBook Pro with Retina display. running 10.8.2 (and Win7 x64, via Bootcamp).
I somtimes experience trouble coming out of sleep with no external display connected, if the MacBook was connected to an external display when I sent it to sleep and the integrated display's brightness was turned all the way down. Basically, the MacBook's integrated display won't light up. I then need to hold down the power button until the machine powers off, and start it up again. Only then will the display come on, and the machine start normally.
I've been observing this with both an external Thunderbolt Display, and a TV connected through the HDMI port. I don't think this is a Mac OS issue, as I've seen similar behavior on this same machine, running Windows, under Bootcamp.
An example scenario: I'll be using the Thunderbolt Display, or watching a movie on my TV, with the integrated display's brightness turned all the way down, and then, while the display is still connected, I will close the lid - The machine will go to sleep. I will then come the next day, and while the computer is asleep, disconnect the external display, and open the lid. The MacBook's integrated display will not light up, the brightness keys will not respond, and I will need to force-shutdown the machine, and start it again - it will then start up, and usually fall back to the lowest display resolution setting (even though I always use much higher resolutions on both the integrated and external displays).
I'm guessing this is happening because the computer is expecting the external display that was connected to it, during its last operation, to still be available, and when it's not - it panics!
Also, I had times where this happened, and a force-shutdown would not do the trick. I had to actually connect back to the external display, wait for the machine to start normally, take the integrated display's brightness back up, and disconnect the external display. The machine would then resume normal operation, and I would be able to disconnect the external display and work on the integrated display.
Has anyone else experienced this, or anything similar?

There we go. Here's the complete Console report, up until the reboot, which fixed things. I can't make anything out of this, but perhaps someone else can.

How to stop sleep/hibernation with external display & lid down

What is the proper way to get my MBA to not sleep, hibernate, etc. when I have an external display attached and lid closed while watching a movie or webcast. In such a case I am not touching the mouse, trackpad, or keyboard.
I have bluetooth keyboard and usb wireless mouse attached.
I also disabled the sleep/poweroff options in the energy settings while watching.
The MBA still would go to sleep or something after 10 or 15 minutes of no agitation.
Also, the Monitor goes blank since their is not signal coming through to it.
Was this just not a use case that was thought through: Watch video stream with external monitor and lid closed? Make sure the MBA knows this scenario invalidates the powersave options????? And yes, the power was plugged.
Thanks

Caffeine puts a little coffee cup icon at the top bar. Click to turn it off and on - it is on when the cup is dark, ie has coffee in it. However, this won't solve your problem - the MBA will still sleep with the lid closed. There are settings to allow use of an external monitor but what I did was download InsomniaX. This little free app keeps your computer from going to sleep when you close the lid. That way you can close the lid, walk down a hall or do something, then open the lid and keep working. Just don't forget it is on and leave the Mac too long or it will run out of battery.
Insomnia isn't in the App store, had to download it at http://www.macupdate.com/app/mac/22211/insomniax

MBA not always recognizes external display after sleep

Hi,
I have a 2011 MBA and use it on a external display (Dell 2709w) with the lid open. The issue with this MBA is that after sleep it often (every second time I wake it up) doesn't show anything on my external monitor. In order that the external monitor works again I have to plug the DVI cord out and in or press recognize monitors under monitor settings.
I also did a PMC and SMC reset but both did not help.
I have also done a complete reinstall witch did not help as well.
I also did a test with a MBA from a friend (exact same model) and his always works with the external display after sleep while mine only works every second time.
Could this be a hardware defect? sound pretty strange to me, but who knows...

I have managed to make the Apple Hardware test by just pressing "D" while restarting. The test, however, did not find any error - but this does not surprise me as I think it only tests the ram.

Internal/External displays blank when external connected while sleeping

When I connect my external display to my MBP (late 2011) while it's sleeping, the MBP awakens but both the internal & external display are blank.
The MBP is running ML and is connected to external display via DVI. No response to external Logitech keyboard or internal keyboard. Currently my only recourse is to ssh in from a co-located Vista machine & 'sudo reboot'.
If MBP has recently been used (say < 5 min or so), everything's fine -- external display fires up & external KBD/Mouse work.
I'd be interested in any way to prevent this problem if I forget to open MBP for a moment before connecting Power/DVI/USB. Alternately, a command
I could issue via SSH to reinitialize display would be great.
Thanks. Kent

Pleased ignore this thread - managed to double post somehow ....? Sorry

New 27inch iMac, external Display "blinks" while in "Display Sleep"

I just updated from a 24inch iMac to a 27inch iMac.
I'm using the same setup for connecting the external display, which is a miniDisplay Port adapter(from Apple) to DVI, then DVI to the external monitor.
All works fine until the "Sleep Display" kicks in, then the external monitor pops up the "DVI-I no signal" warning. This is normal but instead of going away after a couple of seconds it begins to blink as if their is communications going on between the monitor and iMac. So its blinking this message endlessly and thus the external monitor never really goes to sleep.
Since this worked fine on the iMac 24inch, I'm assuming it has something to do with the "Thunderbolt" port, using a miniDisplay port adapter.
The external monitor is a 20 inch Viewsonic VP2030b, running at 1600x1200.
I added a YouTube video for clarity. http://www.youtube.com/watch?v=Q7Zm_U_7sbc

Go to: System Preferences > Displays select the Color tab > uncheck "Show profiles for this display only" and try one of the RGB profiles to see if it is better for you.
Then if you are not happy with one of those..? Try Selecting, Calibrating and Saving a different Profile, other than the default one offered for that monitor.

Trouble getting out sleep mode with external display

My 15" ALPB si connected in closed mode to a Viewsonic external monitor. When not used for a while, the Powerbook will of course get to sleep. But then there is no way to make it wake up again. Disconneting screen and other devices won't help. Only a restart will do, thereby losing all ongoing work. (BTW, never had this problem with a 12" ALPB also connected to the same type of display).
I know that by removing the monitor shutdown option in the energy saving preference panel it will dissapear. But I really need the display sleep option to work.
Someone experiencing this problem? Any solution?
Thanks. Mark

Thanks for your suggestion. That's actually a workaround I've used. The only problem is, the display isn't really put to sleep. The result: I still get an extended desktop and occasionally I "lose" my pointer. A bit annoying, but thus far the only solution I've come up with.

External display lost after resume from sleep on Macbook 4,1

Hi, I'm connecting an external display (with a max res of 1920x1080) on a Macbook 4,1 early 2008 (graphics : Intel GMA X3100) with OS X 10.5.8.
It's connected with an official Apple MiniDVI>DVI converter and a DVI cable.
I had to reset the PRAM and SMC to have it detected.
It worked perfectly in mirror mode... until I put the macbook to sleep : on resume, the external display received no signal, and I could'nt detect it in "monitors / detect monitors".
I checked that SMC is up to date (1.31f1)
When I plug or unplug the DVI cable, or when I switch on/off the external monitor, the macbook's integrated display switches off for a second then switches on back, as if it were detecting something... but without any effect.
Any idea ?

Hi Erwansj,
It sounds like you have done most of the steps in this article, but see if there are some other steps that help, like trying Safe Mode.
