Connecting external display to macbook troubleshoot

Hello
I am trying to connect an LCD monitor to my macbook.. to expand my desktop. I've bought the appropriate VGA Adapter. My issue is when I go to System Preferences and then Display pane.. I don't see the ARRANGEMENTS tab. Can someone please tell me how I can make this work or point me in the right direction. Thank you in advance for your help.

Hi vvarruunn,
In the display system preference pane, click the 'show displays in the menu bar'. This will put a monitor in your menu bar.. Can you see your external monitor listed here?

TV for external display of Macbook air

Is it possible to use LCD TV as external display to macbook air?
I am planning to utilize the macbook air as both portable and station PC. When I am at home, I want to be able to connect it to the LCD TV via HDMI, and then still working with wireless keyboard and mouse.
Is it do-able?
Thanks

Yes, All you need is an MiniDisplay port to HDMI adapter and a HDMI cable.

If you have the 2011 MBair then you plug this into the Thunderbolt port.

Problem Connecting external display

I Have a MacBook Pro 13" from early 2011, 2.3ghz Core i5, 4Gb RAM, Intel HD Graphics 3000 384mb with OSx 10.7.4 (11E53)
I'm having some trouble connecting external displays via the ThunderBolt port using a MiniDisplay Port to VGA adapter.
I have to go the settings -> Screens -> Detect Screens to connect or disconnect any kind of display.

Not sure.
All I did was plug my dell monitor's cable into the mini display adapter and boom, it worked.
Is there any way you can validate that the monitor is working, and/or try this out on another display. Sounds like its either not compatible, or something is defective. (monitor, mini-display adapter, MPB)

24-inch Mid 2007 as external display for Macbook Pro Retina?

I'm a video editor looking for a new laptop. Tough decisions, but these facts may help my decision...
Can I use my 24-inch Mid 2007 as external display for Macbook Pro Retina?
And if so, would the Macbook be able to access the external hard drives that are connected to the iMac? Or do the external hard drives have to be connected to the Macbook Retina?
Retina's picture quality is just incredible but compared to Macbook Pro non-retina you sacrifice: disc drive, port options, customization, anti-glare screen. And its more expensive. Arghh

I would use the retina as the primary screen for the canvas and viewer, while putting the browser and timeline on the iMac.
Apple won't help here. Unfortunately, they leave they're old products in the dust and wouldn't waste time writing an article about connecting a macbook retina to an '07 iMac.
Thank you for replying though Ralph. The answer has to be out there somewhere.

How to connect external display to iMac

which port do I use to connect external display to my iMac ?

Welcome to Apple Support Communities
Depending on the iMac you have, you have different ports: Mini-DVI, Mini DisplayPort or Thunderbolt. Mini DisplayPort is available in 2009 and newer iMacs, and Thunderbolt is available in the Mid 2011 and Late 2012 iMac.
You have to use one of those ports to connect an external display. You will probably have to look for an adapter, depending on the port the external screen has got

Proper way to connect external monitors to macbook pro?

I recently had to have the logic board in my mbp replaced and was wondering if disconnecting an external monitor while computer is on would cause the problem.
Should monitors be connected/disconnected with computer powered down?

If fact, the correct way to connect external displays is to have the MBP on, the external display on and seeking a signal, the external display cable connected to the DVI-to-VGA adapter (if necessary), and then connect to the MBP. So, the last connection is to the MBP, but everything is powered on. That way, the MBP autodetects the display.
Even if you don follow that procedure, connecting/disconnecting a cable from the DVI port would not do anything to your logic board.

Can't connect external projector to MacBook Pro running Windows7. Any suggestions?

Can't connect external projector to MacBook Pro running Windows7. Any suggestions?

Did you try a cable? The point is you did not provide any information about: what projector, how you are trying to connect, what happens when you try, error messages if any, does an external monitor work, what computer you have, what OS, etc.

Suddanly Mbp display has got inverted colors with black on white settings. in universal access. When I connect external display(tv), TV display is normal. I reinstalled os x lion. But it did not help.

Suddanly Mbp display has got inverted colors with black on white settings. in universal access. When I connect external display(tv), TV display is normal. I reinstalled os x lion. But it did not help. I had this problem before but it solved after reinstalling os x lion.
Did you have this problem? What should I do?

Sorry, its not an external display. I changed out THE display in my imac. When I hooked up my wife's display it was photo negative and the imac was color. I changed the Universal Settings and the external display went to color and the imac went to photo negative.

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.
MacBook Pro 13-inch,
2,7 GHz Intel Core i7,

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...

Or any other way to solve it?

Macbook Air 13" (Oct 2010) Locks up when connecting external display

Since I installed Lion my Macbook Air needs to be restarted nearly every time I connect an external display. This did not happen prior to Lion and wondering if anyone has a solution.
Details:
- 13" Macbook Air (October 2010 version)
- Dell 27" LCD display
- Mini-Displayport <-> Displayport cable used to connect

OK. It was a guess anyway.
I changed my screen resolution and then did a search of system files to see what was changed today.
I sorted by descending date/time and that file was at the top of the list.
I opened it with the Property List Editor program and saw it contained the changed resolution, so I took a guess that deleting that file and rebooting would set you straight.
You might look for recently changed files with likely names in your personal settings folder:
~/library/preferences
and try deleting and re-logon (you don't need to restart if you're only changing your own files - a re-logon picks up the change)
Sorry - I don't have a better guess. Good luck

Connecting external display to PreAluminum MacBook

My MacBook does not recognize any external display that I connect via a USB port. What am I doing wrong? Is there another port connection I should be using? My MacBook is the pre aluminum model so it may have different ports than the new generation aluminum MacBooks. Thanks.

Do you have a white or black MacBook? If so, depending on the monitor you're trying to connect to, you'll need something like this:

Do you know what connections this monitor has? (DVI, VGA, HDMI) How old is your computer?

Display problems when connecting Samsung external display to Macbook Alu

Here is the deal:
1. I got a new Macbook Aluminum (yesss!)
2. I got a sweet 23" Samsung LCD display (2048 x 1152)
3. I got a DVI to Mini Display Port adapter
4. I hooked the two up
5. At first couldn't get a resolution higher than 640 x 480
6. Figured it out
7. After the Macbook went to sleep I tried to wake it up using my BT keyboard
8. Screen came up with static/noise and then flashed the desktop off and on
9. Unplugged display, opened Macbook to wake it up
10. Macbook won't wake up. Caps lock key lights up, but that is it.
11. Force shutdown and reboot
12. External display works again, until later when Macbook falls asleep
13. Here we go again
Yes I have downloaded the latest update. I have reset the PRAM, etc. with the help of an Apple support agent. So far, the problem remains.
Does anyone have any ideas? Any solutions other than me having to drive me lazy butt over the hill and taking 3 hours out of my day to have a Apple Genius look at my Macbook?

Don't bother bringing it to an Apple store and wasting your time. I'm pretty sure your problem is a known issue with the software and not hardware. I suggest you get a hold of Apple over the phone, make sure you talk to a "product expert" and not a general rep and I'm sure he'll clarify it with you.

Ongoing fatal crash and security bug related to connecting external display

The infrastructures in OS X to resume from sleep, to authenticate, and to change displays is fundamentally not working.
The security bug I have encountered has to do with connecting a cinema display exclusively to a MacBook Pro. This is a specific situation, but please note that I have experienced the same problem on no fewer than three independent laptop. Plus, the Genius in the Apple Retail Store was convinced of the general instability of this infrastructure. The security problem is that hot corners no longer function if I transition between two states in the same reboot. The first state is where I have the laptop powered on and using its own internal display exclusively (when I'm on the road). The second state is when I have the laptop displaying its output exclusively on an external display (when I'm at home). What happens is that an attempt to use hot corners fails. There is no response. I even added configuration on all four corners (whereas I originally had settings only for the rightmost corners), and even then, the hot corner action (of sleeping the display or entering locked screen saver mode) does not commence. This prevents the user from being able to secure the display on demand using standard methods that are supposed to work.
The instability level related to connecting the external display exclusively is high. Again, I've experienced this on no fewer than three independent laptops, and the Apple Genius at the Retail Store confirmed that this aspect of OS X did not work consistently. When I want to connect the cinema display to the laptop in such a way that the laptop's own display is not part of the active screen, the process I use succeeds about half the time. Supposing I have been on the road, where I am using the laptop display exclusively. I then put the laptop to sleep. When I return home with the lid open, I connect first the USB (power) from the cinema display to the laptop, and then I connect the Mini DisplayPort. When that step works, what happens is that the login screen shows on the cinema display despite the fact that my laptop lid is closed. This is good, and is what I want. At that point, I open the laptop lid and quickly log in.
With Apple being a mobile device company, I rely on the laptop for tasks that one traditionally may use a desktop for. This simply points to the versatility of the laptop. But I'd like the bugs resolved, so that I do not have to hesitate to make use of the inherent flexibility possible with the MacBook Pro.
Here's what happens when the process (of connecting the external display in a way that establishes itself as the only screen in use by OS X) fails. Firstly, when I connect the external display via Mini DisplayPort, the laptop doesn't even respond. Instead, it remains asleep. So to work around it I have to repeatedly disconnect and reconnect the Mini DisplayPort so that the asleep MacBook Pro will see that there is a display connected to it. Also, sometimes that isn't even enough and I have to open the laptop lid, and put it to sleep again so as to trigger whatever actions are necessary to recognise the external display (presumably by having the laptop recently awake). Around half the time, I have to play this game of disconnecting and reconnecting until it actually works. This high level of reproducibility (confirmed by the Apple Genius representative's confidence that this part of the system doesn't actually work) should make it easy for an engineer to look into the problem.
Fatally, and recently, OS X has completely crashed when I have attempted to connect the external display. The external display has gone completely blue, and after a half a minute, it blanked out and my entire laptop became unresponsive. I called Apple Support and was given a case number. I also took the laptop into the retail store to see if I could recover my current session without rebooting. There was no process suggested to make that happen and I was told to reboot the machine. I've had this happen before on other laptops, and it is frustrating that the kernel reaches such a state that it cannot be used. As I see it, this problem is not too unrelated to the way that I need to play a game in order to get the external display connected exclusively. Here are some workarounds that could be added:
Firstly, whenever I connect an external display, I'd like the laptop to see that this has happened, and to take action accordingly (such as resuming from sleep). Secondly, If I connect an external keyboard, and press a key on it, I'd like this to wake the laptop too (in the event that the first method fails for some unforeseen reason). I'd also like the connection of the cinema display's USB power not to cause the laptop to enter into a confused state between asleep and awake. Sometimes I need to disconnect and reconnect USB power in order to trigger the laptop into waking, but that's only because it's not doing it on its own properly. On the other hand, I also ensure that the laptop doesn't have the Mini DisplayPort connected without also having the cinema display USB power connected, because that also is an unsupported configuration.
I've also gotten the laptop to become confused about whether it is asleep or awake. When I open the lid, it seems to enter into sleep mode, but closing it seems to bring it into an active state.
Also, I've successfully logged on and authenticated with the screen showing exclusively on the external display. But just ten seconds after I start using the system, the laptop falls asleep--with the lid open! Whatever triggers that action doesn't seem to be on track. The laptop is open, there are incoming events such as mouse movements and key presses, and the external display is on and is in use. And then the laptop falls asleep! This has happened numerous times. Not only should this not happen; the instances where it does happen can cause further instability and put my system at risk of fatally crashing.
Also, the authentication system itself is highly buggy--far more than it should be. At times I have opened the laptop lid and caught a glimpse of a window before I have begun the login process. Also, an external authentication application that asks for Kerberos/AFS login credentials has been able to overlay itself on top of the primary authentication (whereas I should only see a single login dialog when I need to authenticate to the system). Also, I've had several of these authentication screens overlay on top of one another, although it's been months since I've experienced that one (so it may have been fixed). Also, around a third of the time, the window that authenticates me (on the black background) somehow transfers itself into the background (even though there's only one window!). What that means is what I begin to type my password, and now the laptop starts beeping at me and I need to manually click on the password field and begin entering my password again. This really shouldn't happen, and indicates too much complexity in this authentication process (such as, more OS X code is involved than is strictly necessary, which is likely to make the authentication system more difficult to test). Also, at times, I have been using too much CPU, such that the authentication screen takes too long to emerge. That also means that I'm not able to logon until I uncleanly shutdown the laptop. If the laptop has been asleep, and is revived in preparation for login, then that login screen should be given highest priority, even if there are other heavy CPU or I/O intensive tasks running in the background. And maybe the login dialog shouldn't disappear when the user is legitimately attempting to log in. So even if there is a possibility that the system is under heavy resource use (or there is a stall or minor deadlock), it shouldn't prevent the user from logging in altogether.
At the moment, the very fact that the system shut down uncleanly means that the full disk encryption suite that I used has entered into an undetermined state, suggesting I may lose access to all my data. It's my hope that I can rely on Apple's products to interoperate in a way that won't cause me to be fearful and restrictive in my use, so that I can freely connect an external display at times, and at other times carry the laptop on the road.

Ive got the same problem with Samsung UE225010 monitor too, its full hd but it looks terrible, could it be Displayport adapter issue, because couple month ago Ive tryed with some IPS display, and it looked same bad.

External display with MacBook Pro in Lion

Hello,
Yesterday I bought a Mac OS X Lion, and I found one annoying feature of the system - working on a MacBook Pro (MBP), and very often use an external display, with that do not use display in the MBP. When connecting an external monitor doing video processing,and this activity I was used by Mac OS X Snow Leopard to open the MBP there wasaccess of air to cool the computer. After installing the Lion was the fact that even at very small opening MBP is switched to internal MBP display. This is the functionality of the Lion off somewhere or somehow set? I looked in Preferences, and I have found nothing. Thank you in advance for information on how to solve this problem.

I own a mac mini that stays connected to the 52" LCD 120hz in my living room. The image is perfect, and fits just fine. I did a mini-display port to dvi and got a monster cable adapter for dvi to hdmi which too it to my tv. I did have to go into the tv and set the tv to overscan I think on the image to make it fit and you will have to adjust the resolution on the computer. I can say the colors are darker on the tv and this is just due to the nature of the screen size. Newer LED tvs may be better, but mine is only 1 1/2 years old.
For an external display, just go to the educators link, select your college and you get $100 off. My wife is an educator and I am back in college so it's no hassle. Or they just ask for an ID. I own 2 24" ACD and they are nice. I do photography and a screen calibration is a must. Once done you'll be happy. And docking with the laptop is handy.

Can't detect some external displays with Macbook Pro 17"

My macbook pro 17" connects just fine to my Apple Cinema display. But twice now I've tried to use it for presentations where I am connecting to either a video projector or a plasma screen through some sort of switchbox installed in the room. There's a VGA cable I'm supposed to connect to, and I use my DVI-VGA adaptor for that. But the macbook never recognizes the external monitor. In one case, everytime I hit "detect displays" i would see a brief bit of noise on the external screen like it was about to connect, but then nothing -- and Display Preferences showed no evidence of any connected external monitor. In both cases, I know the host systems generally handle Macs just fine. Is there something different about a Macbook Pro with dual-DVI? A design flaw or a mysterious switch that needs to be set right? Or maybe there's a glitch in my specific macbook??

Have you tried resetting PRAM…
