Shutdown problems with external monitor

Hello.
I'm running Mavericks on my 2012 Macbook Air, running in clamshell mode with an Asus display connected from the Air's Thunderbolt port to the displays DVI port.
My Macbook will not shutdown, unless I disconnect the external monitor. This did not happen with previous OS versions.

What adapter are you using to connect the MacBook miniDVI to the VGA input on the monitor? Is it the Apple adapter made specifically for the MacBook or possibly an older version? Double check that you have the correct adapter, just to rule that out as the potential culprit.
Make sure you are using the recommended resolution and refresh rates for your monitor, from: http://www.viewsonic.com/pdf/userguides/va1903wb-2ugeng.pdf
Resolution Recommended and supported
1440 x 900 @ 60, 75 Hz (60 recommended)
1280 x 1024 @ 60, 75 Hz
1024 x 768 @ 60, 70, 72, 75 Hz
800 x 600 @ 56, 60, 72, 75 Hz
640 x 480 @ 60, 75 Hz
720 x 400 @ 70 Hz
other settings may show up in the Displays, System Preference, even though the monitor can't handle it. Try the different refresh rates to see if that makes any difference. When you have the Mac set up, then use the on-screen controls to auto adjust the monitor, I think this is the Auto Image or Auto set function.
I use a Samsung 204B, 20" at 1600x1200, and sometimes I get some brief flickering when first waking from sleep, but it works fine other than that.

Problems with External Monitor In XP

Ok, I've got a huge problem with XP on Bootcamp.
I've recently got a Samsung TV which I can use as an external monitor. This works absolutely fine when I'm using OSX, recognizes the TV and can use it as a second screen.
When I try to use the same monitor in Windows under Bootcamp, it works as an extension of my desktop, but not able to mirror my desktop. I want to do this so I can play my games on a large screen instead of a small one.
I've trawled the forums on this kind of problem and found a few answers. However, many of them talk about the ATI graphics drivers. I've downloaded the appropriate drivers and the control center from the website, but to no avail.
People have also said about going into display properties: settings: advanced and selecting the ATI tab. I have no ATI tab.
Also with the Catalyst Control Center, when I try to run it, it tells me that I dont have permission to change the settings and to contact my administrator, even though I am the administrator.
Does anyone have any ideas how I can solve this?
By the way. I'm connecting the external monitor via the DVI on my Macbook Pro to the HDMI connection on the TV.
Many thanks
Chris

My logic tells me, if you are using a new MBP the way it's designed is that even if you are plugged in at times it will go in battery mode for a few minutes in order to prevent battery damage, than it will recharge. This happens in the background without notice. However, within this couple of minutes you might notice your display screen to sleep because it is setup to sleep in 1 minute or less in the preference under battery mode. So within that window you might have your screen go blank since the entire process takes a lot more than a minute. I hope this helps.

Inkscape/X11 Problems with external Monitor

Hello,
I´m using Inkscape to create vector art on my MacBook Pro.
Since my update to Mavericks I´m having problems with X11. I have the version 2.7.5 of XQuartz installed currently.
After some troubles, Inkscape opens up just fine.
But I cannot drag Inkscape over to my external monitor, which is based to the right of my notebook.
Inkscape simply disappears.
I´m quite the DAU ;-) with Computers and Software, so it would be nice, if you can help me.
Thanks a lot in advance!
Best,
Sonja

How about trying a native Mac app like iDraw http://www.indeeo.com/idraw/

Problem with external monitor

Hello all,
did you ever use an external monitor with the mac book pro? Once disconnected the external monitor, the Mac freezes and becomes unresponsive. Do you know why?
thank you very much
Fulvio

I have the same problem with my external Acer monitor, starting today. Suddenly, when connected to my MacBook, the Acer monitor says "Input Not Supported". If the Acer monitor is not connected, it says, correctly, "signal not detected".
When the external monitor is connected, my MacBook can see it, has a display preference for it, lets me change resolution, etc, but the Acer monitor simply says "Input Not Supported". This just started today, and I did the system upgrade yesterday. Is there a connection?
I've tried the usual fiddling with connections, rebooting, everything.

Leopard 10.5.2 problems with external monitor

Since I installed 10.5.2 on my macbook pro I cannot have a external monitor Dell 3007 WFP connected to my laptop when starting the computer. The screen will only show up on my laptop but only my background picture but nothing else so I have to perform each time a forced exit. However if I start my computer with my external computer unplugged the laptop works fine and if I then connect my Dell monitor everything works fine. However the closed lid mechanism is not working either anymore. My computer goes to sleep if you press an external keyboard the Dell screen comes on for few seconds but then goes to sleep again. I never had this problem with leopard 10.5.1. Does anyone known an answer to this problem.

I have exactly the same problem. After 4 hours on the phone over 2 calls to Apple Care, they finally let me know that this is an issue with 10.5.2. They said they are working on a fix that would come out with a future update, and offered the workaround of reinstalling Leopard without 10.5.2 update.
They sent me this link about reinstalling without losing files and settings:
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8177.html
It's very frustrating, and I hope they find a fix for it soon!

X240 - Thinkpad Ultra dock Problem with external monitors

I have tried to connect my two external monitors to the dock (the one connected to the vga port) but it was only able to detect one of them (though at a low resolution) and not the other. i have tried using a replicator to connect the screen to the dvi and the usb ports but nothing seemed to work
Did anyone face the same problem and how were they able to resolve it - any recommendation for a port replicator brand / usb to vga display adapter to use that would work?
Thanks

Seems that there is no solution now, because DP MST should be implemented in Linux: https://bugs.freedesktop.org/show_bug.cgi?id=72795

Problem with external monitor when using Windows XP on MBP

Hi All,
I just got a 15.4" MBP, and put Windows XP Home on it using BootCamp. Anyway, the monitor sits above the MBP's screen, as shown below (set up this way through display props, not sure if it matters):
[ ] External Monitor
[ ] MBP Screen
Anyway, some program windows won't drag to the external monitor (Dell 2007FP connected via DVI). An example is AIM. Any idea what it could be? The window shows for about 1/2" on the top monitor, and then it sticks, even though the cursor will continue to move upwards.
Thanks in advance for any advice.
Mike

Hello Gray:
Welcome to Apple discussions.
It appears from this knowledge base article, that you need a USB keyboard to use Bootcamp:

Problems with External Monitor on a Laptop

I've been having a weird problem when I hook my exernal display up to my laptop. It's a Samsung monitor, don't know the exact model number, and for the most part it works fine. But I have an issue when the display goes to sleep. I have my laptop set to put the display to sleep every fifteen minutes. Sometimes when I wake the display, the display will blow everything on the screen up so that it's huge (like 10x normal size or something). If I then put the computer to sleep and wake it, everything goes back to normal, but all open windows and applications are moved way out of place from where I usually keep them, often barely on the screen.
I've never had this issue with a laptop/display setup before, and I was wondering if anyone had any idea of what might be causing it, or how I could fix it? I feel like there's probably a setting somewhere I'm just not thinking of. Any help would be much appreciated.
Thanks!

Hi there merticlese,
I would recommend resetting the PRAM and SMC as an initial troubleshooting step. Take a look at the articles below for more information.

T520 problems with external monitor resolution

Hi,
I am on permanent hold right now waiting for a Lenovo tech support rep, so I thought I would just post my issue here. I just purchased a Dell ultrasharp U2713HM monitor and am trying to connect it to my Lenovo T520. Sometimes it sees the monitor and sometimes it doesn't, but that isn't my main issue. The monitor is supposed to be 2560x1440, but all of the resolution settings are greyed out. I know the Lenovo can support it because my last monitor was a Samsung SyncMaster that supported 2560x1440, and it was beautiful (beautiful until the monitor blew up).
I have been on the phone with both Dell and Lenovo, and so far nobody has been able to resolve the issue. I upgraded the NVIDIA graphics card driver (NVS4200M) to the most recent version (310.90) as suggested by Dell, and I switched out the VGA cable for the DVI-D cable (connected to a Dual Link Adapter), as suggested by Lenovo. It stlil isn't working.
I could use any suggestions. I am not techy at all, so this is pretty frustrating. Thank you!!
Solved!

Okay, another update. I changed the graphics thingy in the bios from NVIDIA optimus to discrete based on someone's suggestion, but that did not work, either with the displayport cable OR the dual link adapter. I also just spoke with the Dell tech, and he basically told me to take it to a shop to see if they could figure it out. In other words, I am out of ideas, and I think I will just return the monitor unless anyone out there has any other suggestoins! Thank you!
Just to be clear, are you saying you have a cable with DisplayPort on both ends and your tried that with the default BIOS setting (Optimus), then Discrete, then Integrated and it didn't work on either of those three settings?

Yosemite Won't Shutdown With External Monitor Connected

Hi there...
I have a MBP 2010 and I've updated Yosemite from Mavericks. Now I'm running the latest 10.10.2.
Ever since I updated to Yosemite, I have had this problem of my computer won't shutdown when an External monitor is connected. This happens only when I put my computer to sleep.However, if I restart the computer and after logged in to the user and tried to shutdown, it shutdown without any problem. Every time I shutdown it just hangs and I had to force shutdown by press and hold the power button. Which I'm sure is not a proper way.
Right now only my external monitor connected to my MBP. So I did unplugged the ext. monitor and tried shutdown and it works fine. But it think this is the temporary solution that I've found but it is annoying to unplug everytime I wanted to shutdown and plug it back in once the computer is up and running. Which is not idle solution at all.
Am I the only one or a lot of people facing this issue? If there is a solution please share. Very much appreciated. Thanks.

Updated to 10.10.3 and the problem still persist. Still unable to shutdown or restart after wake up from sleep.
Any one affected? Is it something to do with Gfx card?

Using the GT70 with external monitor and lid closed

I wasn't sure where to post this question.
I have several laptops and use external monitors. I close the lid on the laptops and the display continues to work.
On the GT70, the system shuts down. It won't allow me to use the external keyboard and mouse or display the session.
Any suggestions if there is a configuration option to allow the GT70 to continue to function with external monitor and lid closed.

Yup. This is a windows setting. You need to go into your control panel -> power options -> "Choose when the computer sleeps" and "Choose what closing the lid does"
That should solve the problem. I currently have my GT70 hooked up to a 42" TV and I can close the lid and it stays on and the TV continues displaying as well. No problems. =]

Mountin Lion has trouble with external monitors

Not so much a question as a shout-out. Since going to Mountain Lion, my pretty new (February this year) MacBook has been having no end of trouble with external monitors. I use it a lot with the clamshell closed with two different external monitors of two different sizes, one at home, one at work. It sometimes thinks the one is the other, or if I unplug the monitor in sleep, when I later open the clamshell, the screen stays black and I have to force a reboot with the power button. Never had these problems with exactly the same set-up in Lion. Sometimes it also refuses to find a connected monitor or projector, I have to pull the dangle and put it in again.

If memory serves, one of the 'flaws' with BM's hardware is that it will not convert on-the-fly. So if your sequence doesn't match what the TV is accepting, you get black.
For example, my TV will not accept 1080p, only 1080i, so working in a 1080p sequence would produce no image for me as the BM will only output exactly what's in the sequence, it can't convert my 1080p/24 sequence into 1080i/30 for output.
Now I'd expect your TV would have no trouble accepting a 720p signal but, maybe the above data will lead you down a path of investigation.

MacBook Pro with external monitor and keyboard.

Hello, everyone.
I've tried to find the answer for this question but haven't found a clear answer with my Google search.
My older Powerbook G4 will not allow me to work with an external monitor and keyboard with the screen in a closed position. I am about to purchase a new MacBook Pro and would like to be able to use it at home with a larger monitor and keyboard but with the lid closed and its built-in screen turned off. Can this be done ?
How can a MacBook Pro be used (turned-on) with external monitor and keyboard while the lid is closed and the its screen is off ?
Thank you in advance for your answers.
Joseph

Hi Niel,
I have the same problem with my MacBook and I followed the instructions you posted. My issue is that when the computer wakes up after clicking the buttons on the keyboard it then quickly goes back to sleep. I can't seem to keep it awake when the lid is closed. I've been searching for an answer without any luck. Any idea how to solve this problem?
Thanks!
P.S. After I finished posting this message I figured out my problem. While fiddling with my computer and monitor, I inadvertently disconnected the power. After reconnecting the power, I was able to wake my computer and keep it awake. A note to other people having this issue: the computer must be connected to a power outlet to run in closed mode.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds.

Mine does that too. The worst thing is when it goes to sleep, then wakes up and keeps running while the lid is closed and it is wrapped up in a case. I am afraid when the hot weather comes it is going to burn up. I am hoping Apple fixes it in the software or they may have a melted MBP to replace.
Then when I open the lid it is crashed running at fill tilt, pumping out heat to beat the band. I am forced to hold the button down and reboot.
I wiped my hard disk and reinstalled my OS, but it didn't help. I reversed my OS to 10.5.0 and it solved the DVI problem but still won't sleep. This post will probably be deleted by Apple, they did it a few days ago. I just don't know what to do, and I consider myself a real Apple expert. Just hoping you realize you are not the only one.
