Using Dual Display. Turn Off MBP Display?

I have no interest in using Clamshell Mode. Is there a way to disable the MBP display while connected to a second monitor with lid open?

To my knowledge, through countless searches, there is no built in way to turn the MBP screen off without closing the lid and sending the system into clamshell mode.
But there may be a third party solution. a Google search and or a search of these forums should turn it up.

I want to have my itunes visualizer on my TV which is connected via HDMI adapter, and still have access to full screen itunes and my desktop on the main display.
Any suggestions? App downloads that can do this? Please let me know.

You can't do it. This has been an issue since Lion.

If you haven't already done so, try this simple step first.

Cannot turn off MBP monitor/display

I have a 15inch MBP running Boot Camp and XP. I am trying to use the "turn off monitor" setting in power options from the contol panel. However when the time is up it does not turn off the monitor...
Also when the "turn off monitor" feature is suppose to trigger, it disables my screensaver.
I don't want my computer to sleep, I just want to turn the monitor off. Right now I just dim the screen until it fades a little but I can still see my desktop screen so I know it is on.
Can anyone tell me how I can turn off the monitor?

Support are now quoting Apple's engineers as saying it is now "expected behaviour" under Lion for the MBP's internal display to reactivate upon opening the lid, even if you want to use only your external display. A new version of the clamshell mode-related knowledgebase article (replacing HT3131) is due shortly confirming this.
This is despite:
- the obvious temperature-related benefits that were achievable (under Snow Leopard) by opening your MBP lid whilst continuing to output solely to, say, a 27" cinema display
- the waste of energy and inefficient use of graphics processing power in needlessly running two active screens (ie if running your MBP in clamshell mode would otherwise make it too hot and/or noisy)
- the negative longer-term impact on the battery and other components from running the MBP any hotter than it needs to be.
If you would like to have the previous behaviour restored, please lobby Apple to change how Lion handles clamshell mode. Options available to them include changing Lion's expected behaviour or adding a user-selectable option within System Preferences.

Turning off MBP Display when Cinema Display connected

Hello,
Sorry if this is a stupid question but I have a 23" Cinema Display attached to my MBP via DVI and although it's great to watch DVDs on, I would like to turn off my MBP display whilst doing this to save energy, reduce the distraction etc - is there a way of doing this?
Help appreciated.

You'd need an external keyboard and mouse as well. Follow these steps:

Alternatively, there are haxies that disable lid-closed sleep:

Setting Photoshop monitor profiles when using dual displays?

I'm using a Macbook Pro connected to an Apple Cinema Display under OS 10.5.8. Both monitors are calibrated and I export from Lightroom to Photoshop in ProPhoto. The Photoshop working colour space is also ProPhoto so there is no mismatch there.
When in dual display mode I like to have my Photoshop application on the Macbook screen and the photo I'm working on shown on the Cinema Display. In fact, I couldn't work any other way because the laptop's screen is not at all suitable for precision work.
I noticed that when I send an image from Lightroom to Photoshop CS4 for further editing the colours were off in Photoshop. This lead me to check the monitor profile used by Photoshop and I saw it was using the Macbook Pro .icc profile. This seems to be used even if the image is displayed in the external display. Selecting the Cinema Display as "default" in ColorSync doesn't change the situation. As a result, the colours as displayed by Photoshop are incorrect.
The only "solution" I have found is to either go to System Preferences > Displays and select the external monitor as the principal one (which is inconvenient because it negates many of the advantages of using dual monitors) or setting the Cinema Display's .icc profile for the Macbook Pro as well (which makes it the one chosen by Photoshop but means I'm only working wiht one correctly calibrated monitor).
Is there a solution to this problem? Ideally I want to have both my monitors calibrated and Photoshop detect which one I'm using to view my photo. Failing that, I would like to have both monitors calibrated and "tell" Photoshop to use the Cinema Display as the principal monitor.I don't want .
Many thanks!

Thanks for your reply!
I'm not too worried about 10.6 because I'm not using it ( I reverted to 10.5.8 precisely because of the colour issues).
I don't really understand your reply. My problem is that if Photoshop uses my Mabook Pro profile as the "monitor profile" my pictures - as displayed on the Cinema Display - look different in Lightroom and in Photoshop. It's as if Lightroom is "aware" of which of the two displays is being used whereas Photoshop can only deal with one at a time. I would like to know if this analysis is correct and what I can do so that Photoshop displays my photographs the same way as Lightroom does on each of my two displays.

Using dual displays

Hello,
I currently have a MacBook Pro with a 19" LCD connected in dual display mode.
What I would like to be able to do is play DVD's on the MacBook Pro screen while "working" on the 19" screen. However, whenever I put a DVD in, I lose the desktop immediately and the movie will only play on the 19" screen. The Macbook Pro screen goes black.
Just wondering what settings I need to change in the system preferences to make this work the way I want it.
Thanks !!

Additionally you will need to turn off the "Dim other displays while playing" preference.

Using Dual Displays G5 Dual Core 7800GT

Hi Gang
Happy Thanksgiving.
I'm editing strickly in SD with an older G5 Dual Core 2.0 - 14GB RAM and nVidia GeForce 7800GT 256MB Dual Port DVI Graphics Card. Most Final Cut editors utiliize dual displays. That being said, wondering if I'd be better off with a PCIe nVidia Quadro FX4500 512MB. I believe my friends Chris & BD here on the forum, may prefer the speed of the nVidia Quadro FX4500. I'm also trying to avoid bogging down the system.
Thank you
Mike

Hello Diesel
Don't think we've connected before. And please don't be offended, I'm a 65 year old Mac user who highly regarded Chris's expertise. He was a bit older than most here, and his experience was impeccable. In my qualified opinion, I've been witness here to countless examples of concieted bloatness and inaccuracy. More so on the FCP forum. In fact, sometimes, despite the higher star rating of a responder, I'll eventually solve my own problem contrary to a short rude incorrect reply, (as though they may appear higher than mighty). But of course this is typical of any forum.
In short, I've found the answer many times lies in different respones from different people. You just have to search.
Getting back to my ole friend Chris, I'm gonna guess he finally got peturbed with all the 'Arm Chair Quarterbacks', (more now than ever).
In any event, here's Chris's well researched list, and I see the X1900 is listed as weaker than the 4500.
http://www.jcsenterprises.com/Japamacs_Page/Blog/71BBF3EF-9713-4C53-8B80-26771F8 A4087.html
I think the answer is that the FULL SIZED nVidia card, (two slots - 512MB), could be more powerful thus preventing a slow down when using two displays.

The other advantage with nVidia, (as taught by Chris), is that XTI cards do not have temperature sensors. I use Temp Sensor all the time.

"Ease of Access - Make the Mouse Easier to Use" will not turn off Auto-maximize

I have a dual monitor setup and any window that I drag over to the right hand monitor gets auto-maximized. A red border appears around that monitor when I position a window (any window) in it. The left hand monitor works normally. I can make the window smaller,
but if I try to move it from the top of the monitor or from the left side then it auto-maximizes.
This problem does not occur if I log onto my wife's user account, so it must be something in the settings for my account.
I see many people asking how to turn off the snap feature, and I have checked the "Prevent Windows from being automatically arranged..." box in the "Ease of Access" item in the control panel" - but this does not fix the problem.
My tale of woe seems a bit different than what I have seen described in various forums.
Has anyone seen this problem and solved it?

Hi,
Here's the way to disable auto-maximize via the registry:
1.Run Registry Editor (RegEdit).
2.Navigate to the following registry key:
HKEY_CURRENT_USER\Control Panel\Desktop\WindowArrangementActive
3.In the right-pane, double click (or right click and select Modify) on WindowArrangementActive, and set its REG_SZ value to 0 to disable ; 1 to enable.
4.Close Registry Editor.
5.Log off and log on again, or restart computer for the change to take effect.
Hope it helps.
Regards,
Blair Deng

Well-used iMac suddenly turning off

My not-so-new 20" iMac is turning off on me. I have used this computer, many hours a day, for several years now. For the past 20 months, I've lived in an apartment with old outlets that haven't been replaced, and don't have great contact with the electrical plugs. I've been using a power strip, and the computer only turned off when someone knocked the plug out of the outlet or bumped "reset" on the power strip.
Starting yesterday, my computer started turning itself off (apparent power failure) without anything getting bumped. I'm not seeing any changes in the lights around, me, either, so I don't think that power fluctuations are the proximate cause. I've fiddled with all of the pulgs, unplugged and replugged them, and the problem is getting worse: my computer is shutting off more often. I'm using my spouse's laptop to ask this question, because it's gotten to the point where my comptuer really isn't useable. I've gotten great advice from these forums before, and I'm looking forward to getting good advice this time.
Could a power regulating power strip solve my problems? I'm guessing no, but should I do this in the future, to prevent damage to my computer? More importantly, what is likely wrong with my computer, and about how much would it cost for me to replace the part, or get it fixed at the Apple store? I did not purchase any extended warranties, so this computer is completely out of warranty.

It's been a month since I first posted, and I've got more clues and details now. After I posted my question I realized that my computer is and has been on a surge protector (and the protector light is light), so on later reflection I don't think the problem is the steadines of the power.
den.thed's suggestion seemed to work at first, although I think the longest my computer has gone without shutting down in the last month was about a week, and at this point resetting the SMC doesn't seem to be helping (not that I've turned the computer back on without unplugging it, so I haven't tested this precisely).
I leave my computer on at night (sometimes I put it to sleep, sometimes it puts itself to sleep, but sometimes something happens and the computer doesn't put itself to sleep, or my cats step on the keyboard and wake it up), and it has not shut down at night. It only shuts down when I'm sitting in front of the computer, using it. This made me think I might be having a software problem, so I tried avoiding using specific programs, but I can't isolate a specific program that is always open or always being used when my computer shuts itself down. I think my computer has only shut down while I'm typing, but I'm not certain on that one. I'm using a logitech wireless keyboard (because I spilled water on and destroyed the original keyboard), and (because I only have the one keyboard at the moment) I haven't tried using another keyboard.
Last night I had the realization that the times my computer was going longer without shutting down was when I'd unplugged my backup HD running Time Machine (because of the limited number of USB connections on the computer). I am not certain if my computer has ever shut itself down with the external HD attached. I have had successful saves to Time Machine on my external HD while dealing with this problem.
But these two clues: maybe shutting down only when external HD is plugged in, and definitely only shutting down when when I'm sitting at the computer, actively using it, don't seem to me to point to the same problem.

User Account Can't access internet once parental controls used, even after turning off parental controls

I set up a user account for my child. I am able to access the internet through firefox. I then set up parental controls and can NOT access the internet anymore. I turn off parental controls for that user account. I still can not access the internet from that account.

Parental controls is a part of the Windows operating system and not Firefox. You can get help here: http://support.microsoft.com/ask-community/windows/

My ipad when im using facetime it turn off, i dont know why?

When im in facetime in a videocall with someone in about 15 sec it turns off and appears the apple and starts again. So when it turns on i cant send facetime again and the wifi dont works well for about 15 min or i need to reset the ipad!
What can i do?

If it's just the apps that you've downloaded from the App Store that you are having problems with, then try downloading any free app from the store (as that appears to reset something) and then re-try them - the free app can then be deleted.

Thunderbolt Display Turns Off/MBP Goes to Sleep in Clamshell when MagSafe unplugged

My battery is fine, but I can't use my 2011 15" 2.2ghz MBP + Thunderbolt Display in clam shell mode without being plugged into power from MagSafe. Disconnect the cable, Thunderbolt quits and MBP goes to sleep.
This drains battery by being constantly plugged in.
I updated my the TB firmware today when prompted. Problem existed before and after.
Let me know what's up, very annoying.

The internal battery could handle the extra power needed when using the external display, but OS X (or maybe the firmware) doesn't allow clamshell mode without external power.
<http://support.apple.com/kb/HT3131>
If it did, the extra discharging and charging would mean replacing the battery sooner.

Can I use Dual Displays with New Mac Mini (HDMI Thunderbolt)

Hello Everyone,
This question may have been asked before... but I just purchased a beautiful new Mac mini and it has an HDMI port in the back and a Thunderbolt port. I am using a new DELL 23" HDMI monitor that also accepts DVI. I think I could run another monitor on the Mac Mini, but I don't know which is the best way to go... I purchased a mini-display port to DVI adapter because I heard thunderbolt could accept the mini-display cable.
1. Should I purchase the other identical Dell monitor and then run it on Thunderbolt 2 DVI and run it DVI
2. Or is there a HDMI splitter that splits the signal into two cables and go that way?
Any advice would be greatly appreciated Thanks!

I just got the mini server and run a 24" LCD off the HDMI port and a 19" off the displayport (adapter to DVI) and it works a treat there's no need for any splitter.
