External Display w/o Internal Display, More elegant way to do it?

My desk has a spot for my MBP and a 19" LCD monitor connected via DVI cables. currently (to dissipate heat as i play warcraft) i have to leave the MBP open, and turn down the display brightness to 0.
Is there an way to get this going automatically? the F7 button only switches between mirrored mode or not. I would like to disable the internal display all-together, rather than dim it to 0.
suggestions? programs? anything?

as for a solution, i have found one!
simple too... in this order:
1. put the computer to sleep with lid shut
2. attach an external monitor (i've used DVI, im sure VGA will work too)
3. attach USB keyboard & mouse (i've used a combo wireless logitech)
4. attach the power adapter
5. wake the computer from sleep with lid closed.
6. open lid (after the computer fully awakes)
upon completion the internal display is open but the lcd is in fact disabled.

IPod touch - more elegant way to sync to a new library?

I recently had to change the motherboard in my machine, and took the opportunity to upgrade the machine and put on a fresh install of the OS. I had expected my iPod touch to work like every other device I've had and just sync with a new install of iTunes (ie pull everything off the device and onto the host machine and be up and running without further action required), but unfortunately it gives me an error saying:
This iPod "..." is synced with another iTunes library. Do you want to erase this iPod and sync with this iTunes library?
When I click cancel it lets me do most of what I'd like, but unfortunately it won't let me do a firmware update (from 4.3.4 to 5.1.1) as it says that:
There are purchased items on the iPod "..." that have not been transferred to your iTunes library...
I have done a backup of the device successfully, so I'm guessing that I can say yes to the 'erase the iPod' prompt and then just restore it when complete, but before I do that I want to be 100% sure that this process will back everything on the device up (ie after the process will the device function identically to what it is doing now). Unfortunately the backup process just completes without providing any details, so I have no way to verify that and would appreciate more detail on this front (or if it will restore the link to the old iTunes library as well, at which point I will have just wasted my time)? As such, I havn't been confident enough in this process to go about risking the erasure.
The other thing I am wondering is whether the syncrhonization process and/or backup functionality store system level settings as well or just the data? For instance, entering my WPA2 key was a royal PITA when I first got the device as the UI isn't really well designed to handle long, cryptic encryption keys (no way to show the characters as you enter it (ie can't double check it before clicking okay), no way to paste it from an email, etc.) and I don't particularly want to go through that process again.
Ideally, I'd like to find a more elegant way around this (ie I'd really like to avoid having to wipe the device) as this is kind of a ridiculous process to have to go through for such a simple task. If it helps, I still have all of the old files (the new OS and iTunes were installed on a new HDD, so the old iTunes folder/data is still on the old HDD (can't boot to it on the new hardware, but Ican access the raw files)) so if there is some way to convince iTunes to just load up those files and be done with it I'd be very appreciative.

You need to:
Transfer iTunes purchases by:

- Transfer othre music by using a third-party program like one of those discussed here:
Copy music
- To retain app data and other information, connect the iPod to yur computer and make a backup by right clciking on the iPod under Devices in iTunes and select Back Up
- Restore the iPod from that backup
Note that the Backup that iTunes makes does not include synced media like apps and music.

Searching for a more elegant way to write my where clause.

Hi,
I have a table T which has two columns : X(Varchar2(100)), and Y(Varchar2(100)).I want to know all the rows in the table T for which two conditions are simultaneously true: the first condition is X is not null or Y is not null, and the second condition is not(X is not null and Y is not null). So I write my query like below:
select *
from T
where (X is not null or Y is not null) and not(X is not null and Y is not null)But the way I formulate my where clause doesn't seem elegant to me. Please, could I obtain the same result with a more elegant where clause?
Thanks.

Internal display color is wrong, outputs just fine. GPU or lcd trouble?

Hi there, I'm doing some troubleshooting for a clients son. He has a 2008 macbook air, A1237. It boots, but the internal display looks all wrong. The colors are low res and very washed out. However, when I have it connected to an external monitor the display appears fine. Even when holding down option on boot, the graphics are the same washed out quality. I have a couple pictures here. For some reason the kid completely removed OSX and has Win7 installed... I can't explain that. Anyway, I was wondering if anyone has come across this and if you're thinking it's a GPU issue or maybe just a broken display. I tried to determine if the kid had been rough with it and he insists he just turned it on one day and it was like this. No external damage from what I can see. I've attached a picture showing the two displays side-by-side.
If anyone can help me determine where the problem is I would be very grateful.

So, a quick update. I started by checking the display cable connection on the logic board. It appeared fine but I re-seated it anyway. But the display was the same. I then blew out the Win7 installation and re-installed Snow Leopard. Throughout the install and the subsequent boot up the internal display was the same as it had been; all the colors looked inverted, dark and lo-res. So I hooked up an external monitor to check out some statistics and when I first connected it, it showed up as an extended display. I chose to mirror the display and the internal display turned back to normal! All bright and Snow Leopard purple! I rebooted and the white screen showed up on start, where before it had been black. For one moment on reboot the white did invert to black, but only for a moment. It's currently back to the desktop, looking normal and I'm running updates. Any ideas here, at all?

How can I disable the internal display on my MacBook Pro with connected external display?

I used this metod with the MagSafe power cable connected (see http://osxdaily.com/2012/06/15/yet-another-way-to-turn-off-internal-lcd-display- of-macbook-pro-with-lid-open/).
Open System Preferences and click “Mission Control”, then click on “Hot Corners”
Select a hot corner and pull down the menu to select “Put Display to Sleep”
Now connect the external display to the Mac and move the cursor to the newly created sleep corner to turn off the internal display
Close the MacBook lid and wait a few seconds before opening the lid again, the internal display should stay off while the external display will be powered on
This worked great under Mac OS X 10.7.4, but after the last update to 10.7.5 it doesn’t work more. The built-in display turns off really, but a few seconds after opening the lid it lights up again. Do you have any suggestions? Dimming the brightness or clamshell mode is not very useful.

Thanks!

I have the same problem: not able to work with my external display mirroring the internal one - while shutting the internal display off.
I believe there is an issue with Mac OS X Lion 7.5 that Apple needs to solve, since apparently it does not happen with this version of the OS only...

Two External Displays and Internal Display Over Different Connections

Hi there.
I'm going to be purchasing a rMBP in the very, very near future. However, I am unclear about how external displays work with this. My current display setup at work is two basic 1080p monitors that can be run over DVI, VGA or HDMI. I'd like to keep using these when I start using the rMBP but also gain the advantage of a third screen by using the internal display at the same time (so much space for activities!).
One of the thunderbolt ports will need to be used for an Ethernet connection (there is no wireless here), so this leaves the setup needing to be one monitor run via Thunderbolt -> DVI and the other monitor run via HDMI.
The internet in general isn't being entirely helpful with this. I'm looking for a clear answer of whether the rMBP will run the internal display and the two external displays using this setup under OS X. Some seem to believe that it won't work using different connection types, for example.
Thanks for any help.

Hello dljfield,
Thanks for using Apple Support Communities.
If you'd like to use multiple external displays with a MacBook Pro with Retina display, then please take a look at the information outlined below. A 15" MacBook Pro mid-2014 can support up to two external displays using different outputs.

Need to run a PowerBook with NO INTERNAL display on an External display

So basically I have a TiBook that has had the display removed. I plan to run the machine using my lcd tv. Well, after hooking everything up, all I get is a blue screen. I'm assuming that the computer is looking for the original display. How can I have the computer ignore the internal and run off the external only?
Message was edited by: kipiscool

Easiest way would be to place a small magnet over the spot in the TiBook where the magnet sensor is that detects when the lid is down. Do you still have the display? You can fish for where the magnet is located behind the display by putting it face-up on a table and using a paper clip at the end of a thread or piece of dental floss. Wherever the magnet is, the sensor would be located opposite of it.

Specific Settings for external and internal display modes?

Does anyone know if there is a way do have different settings that adapt to whether I'm using my Macbook's internal display or am docked to my 23" external Cinema Display at home? It would be nice if the Dock would be small and on the side "internally" and large and at the bottom "externally." Also its a pain if I've expanded a window on my external, then disconnect and have to tidy up my windows again so they fit on my smaller internal dispaly

Internal display dead, external display works fine

Hi,
I left my machine unplugged over the summer. When I came back, the internal display was dark.
The machine was making all the right noises at startup, and the Caps Lock key worked, and I could make it beep louder and softer with the volume F-keys, so I hooked it up to an external monitor. It works perfectly with the external monitor.
I went through the troubleshooting procedures - zap the pram, reset the power manager, boot from a CD - no video on the internal display.
While connected to the external monitor, I ran the System Information program and looked for the internal display device. It wasn't there! Only the external one shows up.
Does anyone have any suggestions?
I can post screenshots or System Information reports if anyone wants them.
Thanks,
Doug

Someone took it off my hands. They're going to use it with an external display.
Thanks all!

Internal display normal during start up but goes black with external monitor showing desktop

My MacBook Pro (2.4 Ghz, Santa Rosa with infamous nVidia card) acts strange. It shows the normal gray screen with Apple logo and animation flawlessly during start up but the internal display goes black without any rendering at all when all is loaded. (shining a light on display show nothing) If an external monitor is connected through the DVI port it will remain black during start up and then show the desktop as the internal display goes black. This happens both while booting to Mountain Lion and Windows XP. I have checked "About my Mac" and only the external display is listed. The same is the case if I use the nVidia Control panel in Windows XP.
My questions: Is this a hardware problem or is it related to software maybe even firmware? What controls the display during start up, graphics card or something else?

I found an article about the same issue. Screen looks exactly the same with bloated apple logo.

Internal display stops working after External display connected.

For an unknown reason, starting today, my new MBP will only allow one display out, and "Detect Displays" does nothing to help the problem. Any thoughts on what could be causing the issue? A restart doesn't fix it.

Hi btr94,
As a first step, I would suggest first resetting the [Parameter RAM|http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html] and if that does not work then [resetting the SMC|http://support.apple.com/kb/HT3964?viewlocale=en_US] on your MacBook Pro.
Let us know if this does not help.
Best of luck.

Internal display off when lid opened?

Hey guys!
Just installed Lion and one thing I immidiately noticed is the way Lion handles internal display when external display is plugged in. I use a big 24-inch display with my early 2011 MacBook Pro. I like to open the lid for better WiFi connection but dont really like the display to turn on. In Lion, it automatically does so I have two displays.
Is it possible to open the lid but still keep the internal display off and only the external one on?
Thanx!

Support are quoting Apple's engineers as saying it is "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 wifi connectivity benefits of having the lid open
- 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 or you need it open for wifi)
- 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.
Feedback can be submitted here:

Clamshell mode thinks internal display is running

I use my MBP with an external display. Unfortunately, it always thinks that the internal display is still running even after I detect displays. The MBP is closed and I use a USB mouse and keyboard. The pointer can easily get "lost" off the screen. I've reset and restarted but the problem always comes back.

I just open my MBP before plugging up the TB display. Then after the TB comes on, I close the MBP back into clamshell mode. Works better for me that way.
Does that work for you as well?

PDF printing "Internal display" settings 'default'

Hi All,
I'm having problems PDF printing web applications made in WAD 7.0.
We have created a button triggering the EXPORT command and left everything set to 'default'.
Internal display = 'default', Data binding = 'default'.
All our 7.0 web templates contain text elements (title, etc.), an INFO_FIELD_ITEM block (with tray), a FILTER_PANE_ITEM (with tray), CONDITIONS_LIST_ITEM (with tray), EXCEPTIONS_LIST_ITEM (with tray) and one or more ANALYSIS_ITEM and CHART_ITEM (all with tray).
Everything except the FILTER_PANE_ITEM end up in the PDF, however not all present the tray. Only the conditions and exceptions have a tray in the PDF. Since the tray contains the name of what the it represents underneath, especially the analysis and chart item need to have the tray displayed.
How can I switch this on generically (not for each report individually)?
I don't know which Internal Display webtemplate is chosen when it's set to 'default'. It's not 0ANALYSIS_PATTERN_EXPORT, because if I set the Internal Display to 0ANALYSIS_PATTERN_EXPORT, my output changes completely (and not for the better).
Can I find the 'default' Internal Display somewhere in the system? SPRO? I'd like to adjust the default value to always display a tray.
Any input would be appreciated.
Thanks,
Eduard

Thanks Arun, but Excel export is not the issue.
All the info fields (title, user, date, webtemplate name, etc.) we can print and that's all fine. But... We need the tray of the ANALYSIS_ITEM and CHART_ITEM to be visible. The tray contains the name of the query (DP1, DP2, etc.) and we'd like to see it.
Now, if a webtemplate has more than one chart, the PDF will not tell you which chart is which. The title of the tray is automatically filled in the WAD (with the query name) and we don't want to manually add titles to all chart and graph items. We'd have to do this for all webtemplates, which should be necessary.
Besides, the conditions and exceptions items dó show a tray. Why not for the ANALYSIS_ITEM and CHART_ITEM?
So basically, what I'd like to know is: Where I can find which "Internal Display" webtemplate is used as 'default' and how I can edit it? I know that it isn't 0ANALYSIS_PATTERN_EXPORT, so which one is it then?

Switch off imac internal display

Hello,
i bought an 24" external monitor yesterday. I want to use that external display only. How can i switch off the internal display of my imac?
Lowest brightness and a black desktopbackground are not very satisfying to me .
Thank you for any ideas.

Thank you Eric for your advice about the black desktop background.
But you have the opportunity to switch off the display on an apple mobile device. Why not on an imac? Just a few lines of source code
What will happen if i disconnect the lcd panel from logic board?
