Screen sleeps during Media playback (With external monitor connected)

Here's a weird one...
With no external screen connected to my T410 I can watch the BBC iPlayer without the screen 'sleeping' after 5 minutes, which is perfect..... as I don't want the screen dimming and then going into power save mode while watching anything.
However when I connect an external monitor, in Extended desktop mode, whenever I watch the iPlayer the screens shut down after 5 minutes.
Im sure there's a setting but just cannot find it.
Any help appreciated
T410(2537) -- i7 620M - Intel HD GPU (1440 x 900) - 8GB RAM - 128GB Crucial M4 SSD - 250GB Hitachi HDD - Windows 7 & 8 Pro

Has anyone experimented with tip 2 (active corners)? Perhaps it still works.

Yosemite: Turning off Macbook Pro screen (lid open) with external monitor connected

Here we go again, this worked pre-Yosemite. Now it seems this trick no longer works. After following these steps again the screen on my Macbook Pro now turns on after logging in and opening the clam shell.
Anyone figure out/know a way to turn off the screen on the Macbook Pro with external monitors plugged in? (yes, closing the clam shell–but I'm referring to keeping the clam shell open with the display turned off)

To execute in Terminal:
sudo nvram boot-args="iog=0x0"
To undo in Terminal:
sudo nvram -d boot-args
Once you type it into terminal I believe you need to enter your password. I then restart my machine. Now the TRICK is to either restart your machine with the lid already closed (hit restart then slam the lid!) OR turn the machine on for the first time (then quickly slam the lid!) once you are past the login screen you can open the lid.

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?

Black border on DVD playback with external monitor...why?

Hi all,
I've got a late 2011 MBP 13". Very happy with it (although use is limited as a DJ laptop - and, since I moved abroad, as the basis for a home cinema) and was quite happy to watch films / TV on it as it came. However, I wanted to be able to watch with other people and so have invested in an external monitor.
I have bought a Philips 23" V-line (model number 236V3L). I am completely happy with the picture quality etc but just have an issue during DVD playback:
The image (on fullscreen mode) has a 2" black border all the way round. I've tried fiddling with settings etc but can't seem to lose it...and don't know why. I wouldn't mind but obviously my 23" image is significantly smaller as a result.
Can anyone tell me why? When using the laptop in any other way (i.e. whilst typing this post) there is a 3/4" border on the left and on the right (but not at the top). Is it something to do with the aspect ratio? Is there anything I can do to fix it?
Looking forward to hearing your thoughts...
Regards,
Fin

I use my laptop and a Samsung SyncMaster as my main screen and my MBP as the secondary. I can drag the DVD window to the laptop screen, and then put it in full screen mode. Here is where the problem lies: When I click any application on the primary monitor, the DVD screen shrinks back to normal size.
In DVD Player's "Full Screen" preference. enable "Remain in full screen when DVD PLayer is inactive".

IMac will not boot with external monitor connected

Hi everyone,
I have a mid 2010, 27" iMAC. If I connect an external monitor to the Mac (using display port), everything works as it should. If I try to reboot or do a cold boot while the external monitor is connected the system boots to a white screen and no further. Sometimes I get 2 spinning colored wheels, but nothing more. If I let it sit at the white screen long enough the screen saver kicks in and everything goes black, move the mouse or hit a key and the white screens come back.
I've tried a few things (that I've found on-line) but I'm an old PC user (25+ years) so I'm not used to or know all the tricks or what I really should be trying.
I just upgraded to Mountain Lion thinking maybe that would help, but no change.
Any help would greatly be appreciated.

Sorry about my lack of details, I am using the Apple brand of display port to DVI adapter, a DVI cable that is plugged into an ACER 26" monitor (not sure of the model nuimber right now as I am at work). This monitor and DVI cable worked fine during reboots/shutdowns, etc while connect to 2 different Intel based PC's that I have that also run dual monitors. As I mentioned I've done PC work for many moons and would know how to check for drivers, etc, but now in the Apple environment I am lacking these same skills. So I've done all the standard stuff, switching known good cables etc, but I am unsure of how to uninstall drivers and those type of tasks if need be. I know it could be a monitor problem, but that same monitor works fine while connected to the PC's that I have.

Random pauses during media playback with WH-920 He...

Currently running Windows Phone 8.1 on a Lumia 925.
Bought a pair of Purity WH-920 earbuds when my old Senheisers bit the dust (after 3 years), and loved them for about 3 months... Had the right channel die, and the replacement pair only lasted a month before they went down with the same problem. Currently just got my second replacement pair... fingers crossed.
My question is related to playback after I got my first repalcement. I noticed that I was having a lot of problems with my music app and podcast app randomly pausing, requiring me to either wait 5-10 seconds before it would resume through the remote, or pulling the phone out to resume playback through the screen.
This issue seems to be related to the phone being in my pocket. If I use it on my desk with headphones, it seems to be fine, but as soon as it goes into my pocket the pausing issue starts. I'm being very careful to not crimp the cord in my pocket, my phone sits in it vertically with the headphone cord coming straight up and out... Is this a known issue with this product? If so, is there a way to fix it via a setting on my phone? It defeats the purpose of having headphones if I can't move while listening to them... It I want to listen to music while sitting still at my desk, I have speakers for that.
Thanks in advance!

I have the same MB and CPU but I am using the onboard sound and have not had any problems with that.
I can recommand that you bump up your memory voltage to 2.6~2.7 and loosen up your memory timings to something like 2.5-5-5-8-2T.
Then remove all drivers from your Audigy, disable your onboard sound and remove those drivers, shut down and install your Audigy and boot up allowing Windows to find your new hardware and then install the drivers.

OS X 10.8 Sleep on lid close with external monitor

I have just upgradet to 10.8 Mountaiun Lion and i have noticed a strange bug.
When I have attached my secondary monitor and i close the macbook it doesn't go to sleep.
The laptop monitor is turn off, the main still remains working and no sleep.
How can I sleep my MAC when i close the laptop with attached secondary monitor ?

I have a comment and a question:
Comment: I can connect to my Dell monitor that supports 1920x1080 using either DVI or HDMI and get the full resolutions of 1920x1080 no matter what (at least that is what Mountain Lion reports). Any video I watch seems to be at just fine when viewed at a distance or up close. Granted that the monitor is not 51" like yours, but still...
Question: For my own knowledge, how are you determining that you are seeing the video at a lower resolution? I am curious because I don't notice this, and can't figure out how it could happen unless the source was 720p instead of 1080p. Can you give me some pointers on how to check for this?

Can I use MacBook pro A1211 with external monitor, screen has died but

CCan I use MacBook pro A1211 with external monitor, screen has died but computer seems fine

Hmm seems like this model has DVI out. You could just plug a standard DVI monitor into that. Or use the DVI connector (VGA supported with included adapter; S-video and composite video supported with optional adapters) adapter that came w/ your machine.

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.

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. This only happens when using the external monitor. Does anyone have any suggestions?

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.

CS5 Playback Settings grayed out and no longer can set playback on external monitor.

I like to view my projects while editing on an external monitor but the Playback Settings are grayed out. I've done all my prior projects with external monitor display enabled with no problems and can go back to a prior projects completed and view them using an external playback monitor. For some reason, the Playback Settings on my latest project are grayed out and I'm not able to set Desktop Video Display During Playback.
The last project worked on was about 3 months ago. Last week, I started working on two new projects and noticed that I wasn't able to set playback to my external monitor. All my devices are hooked up and I can review older projects on the external monitor but can't set two new projects to use display on the external monitor.
Anyone have any ideas?
Problem solved. My fault.
The Sequence Preset Settings selected must support the device the external monitor is connected to. In my case, IEEE 1394 firewire. I corrected the new project to the correct Sequence Settings and can now view playback on the external monitor.

"The Desktop Video 9.7.5 software update allows users to take advantage of many new features in the Adobe Creative Cloud desktop applications such as powerful new editing timelines and shortcuts and audio mixing with Adobe Premiere Pro® CC and new creative and visual effects tools with Adobe After Effects® CC."
So everything should be covered on that front. And as I listed, I was getting playback out of AE CC, so I feel it is solely an issue in Premiere. That was worth checking out though since CC is so new. Thanks for replying.

Busted screen, external monitor connection won't work

My PowerBook G4 screen busted a year ago after it fell off a table. I had been successful is using an external monitor up until a couple weeks ago. I have tried a couple monitors and cannot see anything but a white screen. I know a signal is getting from the Mac to the monitor, but only a white screen.
Any ideas on how to get an external monitor connection again?
Thanks.

Hi, Bob.
I know a signal is getting from the Mac to the monitor...
How do you know that? Does the external monitor display something other than a white screen at any point during the startup process? In other words, can you really be sure the Mac is ever sending anything other than plain white to the monitor?
As louie says, there's almost no testing you can do without a working display.
What changed a couple of weeks ago, just before you started having this problem with the external monitor? Had you moved the computer and/or the monitor, connected any new devices, disconnected the monitor, upgraded your OS, etc.?

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.

Start up difficulties with external monitor

When I start up my macbook pro all is well BUT if I start up with the external monitor connected (ACER) I get stranhe lines across the screen for a few seconds and then it clears and the Mac works well. An ideas please

All I can suggest is reset the #1 reset the SMC, perhaps a #8 OS X only Reinstall may fix a software issue.

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. =]
