MBP i7 and Dual External Displays

is it possible to run 2 external 1200x1600 dvi(digital) displays from a MacBook Pro 15" i7?

The cheapest way to do this is probably to use the mini-display port for one monitor , and a USB or firewire based video out card for the other.
It may produce some latency issues , but if you need a cheap fix it might do the job for you.

XP on my MBP and an external display

I am posting here because I got no love in the boot camp directory. Hi, I have a macbook pro (2.33 GHz intel core 2 duo) that I use for both work and home. We are remodeling our home and I am finally getting a home office put in. I have dreamed for years of getting a large external display for when I work at home. Some of my work requires Windows programs, so I bootcamped my mbp, installed windows XP (SP2) on the other side of my computer and everything is great. My question is once I hook my mbp up to an external display and external keyboard (and mouse) will I be able to reboot it in windows and have everything work (the external display, keyboard, and mouse)?
I searched somewhat through teh forums and couldn't find anything, but it is highly likely that I missed if this question has already been answered, so sorry about that.
Any help/suggestions is appreciated.

If your external display, keyboard, and mouse are all Apple products, then you should be okay, as you would have installed all of the necessary drivers when configuring Boot Camp on your Windows XP partition. Check the Boot Camp installation guide for more information.
If your external display, keyboard, and mouse are of another make, you may have to download the required Windows drivers from the manufacturers' website.
I have had a few different screens work on the XP partition of my MB Pro with no problems.
Good luck!

MBP or Air - using external displays

Hi All,
Looking at getting a MBP or Air for work, want to know how easy and how well Leopard goes from dual display to single display. I'll be using a VGA adapter initially.
My current MS laptop doesn't handle being plugged into, or unplugged an external display - the display settings often seem to change by themselves. However, it is the devil I know - is Leopard better, or worse?
Looking for general experiences using a MBP or Air OPEN with a second display.
Do you need to put the computer to sleep to plug or unplug the display?
Cheers, Chris

Hi WBW,
Thanks - sounds pretty good.
A follow up question - when using dual screens, I can place some applications on the second (external) display. When I unplug the external dispaly, how does Leopard handle this? Do the apps reappear on the laptop screen, or are they in another 'space'?
Can spaces be used in conjunction with an external display?

Upgraded to Yosemite and now external display is not detected

I just upgraded to Yosemite on my 2009 MacBook Pro and now it won't detect the external display. It worked perfectly before the upgrade. I have the display connected by USB. Is there anything that can be done about this? I really need that external display for work and am really regretting downloading Yosemite.

Exactly the same issue. My Eizo Coloredge was working fine after installation until (just now) I dared to do a restart...
I have tried various different displays and connections over the past 20 minutes and have restarted my mac (late 2013 MBP 15' Retina) and connected / disconnected multiple times. Neither my Coloredge via Thunderbolt or HDMI (no signal detected) is recognised, nor a Samsung LCD via HDMI.
SO frustrating that something this basic should now be 'broken' when it was fine under Mavericks (and earlier OS). Come on Apple, let's get a fix. Plenty of people rely on external monitors.
Sigh.

Unibody MBP owners with *working* external displays, please chime in.

I'm trying to determine if there's any use at this time to try to exchange the MBP (unibody) I have now with another unit in the hopes of getting proper external display support. (To be clear, I'm referring to the external display problems many of us are having, like in this thread, and this one, and others.)
I'm sure there are others suffering from this problem who are simply seeking another datapoint in determining whether or not exchanging one's unibody MBP for another are of any use at this time. So the question here is:
If you have a unibody MBP, and you are successfully driving an external monitor without issue (using the Mini DisplayPort to DVI Adapter), can you kindly post the following information?
1) External display model (manufacturer and model)
2) External display screen resolution
3) Any information about DVI cable, length, brand if applicable, etc.
4) Have you confirmed proper operation in both 9400 and 9600 GPU modes?
5) If you know, is your MBP equipped with the 9c84 or 9c85 built-in display panel?
6) If your setup wasn't originally working, but now is working due to a unit swap or swapping out of the Mini DisplayPort to DVI Adapter with a new one, can you kindly note that?
Please do not consider yourself representative of a properly working external display setup if yours looks mostly good, with just minor artifacting--that is, for the purpose of this thread, please consider "working" to mean only perfectly normal operation of an external monitor from your unibody MBP.
Are all of the above points necessarily relevant? I don't know yet, but I figured it's best to try to get as much information from those who have working units, to try to determine what's relevant and what isn't.
Why am I asking this? Because I've already wasted enough time with this unibody MacBook Pro, now on my third unit, and I do not want to waste time making trips to the store to exchange units (and the time necessary for restoring to the new unit, etc.) if it's not going to help things. (The previous two replacements had nothing to do with this particular problem, and I didn't have my external display until the third unit, so have no idea if the previous two suffered from this particular problem or not.) If it seems that an exchange from one unibody MBP to another isn't going to help, then those of us who need to resolve this might learn more information with which to make a decision. Right now, I'm seriously considering exchanging for the current 17" MBP with matte display, even though it's not the new unibody design, and doesn't quite match up in the specifications with the new 15" MBP--I just need to get my setup working, and figure the older style of the 17" might be more tested and worked out.
Thanks in advance to those of you who fit the bill and answer these questions.
NOTE: If you have more relevant information to ask of those with working setups, please do; but please avoid the discussion of your problems if you're among the ones (like me) with external display issues, as there are other threads for the discussion of that (like the ones linked above). Ideally, I envision this thread as more populated by the responses of those with working setups.

Mine works perfect.. This is AFTER a logic board replacement for the 9600's BSOD problem
1) Dell 2007WMP
2) 1680x1050
3) Cable that came with monitor
4) Post repair only really using 9600, though 9400 seemed fine too
5) LG (9C84)
6) Logic board replaced last week for BSOD problem. (That board had external monitor refusing to wake problem as well).

Displayport MBP 15" and 30" Dell display - will it work?

hello all,
I have read a lot of discussion items, but I am yet to find a definative answer. I am currently using my MBP with the dell 24" display, using a mini displayport to displayport cable which is working perfectly.
I am considering upgrading to a 30" display, but are concerned that I am going to have problems. Can anyone confirm that this is going to work with a 30" display and displayport connection?

Hi tele_player- the dell 30" (3008WFP) also states that it supports Displayport connection, which is the connection I use now to the Dell 24"
I believe that displayport supports up to 2560 × 1600 which is the top native resolution of the dell 30".
I know there are problems with the dual DVI - hence my specific questions about the displayport combination.
any input greatfully received

MBP no longer drives external display @ 1920x1200

I have been using an external LaCie 526 display on my MBP at the native res of 1920x1200 for almost a year. Today after running a keynote presentation on an LCD projector (may be coincidental) I can only get the dvi to drive it at 1280x720. All of the standard rubber chicken tricks don't have any effect (reset PR, detect displays, turn on/off mirroring, etc). Like many others in this forum using the DVI to analog svga connection does allow the higher res.
Any suggestions much appreciated.

Lots of people are having issues with external displays since there was a manufacturing defect with the nVidia 8600M graphics chip inside the Macbook Pro. You may want to run the Apple Hardware Test from the cd your Mac came with and see if it gives you any errors with the video controller.

2013 iMac 27" and 2 external displays

Hi Guys,
So my setup is a 2013 iMac 27" with a 27" Thunderbolt Display on one side and an 27" Cinema Display on the other...
The question I have is...
Can i configure my audio so basically both speakers on one external display + one of the internal ones become the Left channel and then both speakers from the other display + one from the internal speakers become the right channel
Its a bit hard to explain so i've made a diagram to illustrate:
[IMG]http://i256.photobucket.com/albums/hh187/PharaohSam/Speakersetup_zps94899a5c.jpg[/IMG]
So I want Speakers 1, 3 and 4 to act as the left channel and Speakers 2, 5 and 6 to act as the right channel...
I've done a bit of reading and Googling and OSX's "Audio Midi Setup utility" (used to create an Aggregate Audio Device) seems to show some promise but I can't figure out how to configure multiple speakers to one "channel" so to speak?
Maybe I need a third party app?
thanks in advance guys

I would love to know the same.
Ideally I would like to have the speakers on the left monitor for left sound and the speakers on the right display to act as the right with the main iMac speakers doing noting?

How To Run Dual External Displays

Hello,
I have a MacBook Pro 13". I am wondering if it is possible to run dual external monitors? I have the MiniDisplayPort To DVI adapter, works great with one monitor, but can I run dual? Thanks.

You could try plugging in this USB adapter, it says you can plug in up to six per computer. If you want two externals, you should only need one of those USB adapters because the first monitor should be plugged into your superior onboard DisplayPort.
Just bear in mind that when you use these USB adapters, the top resolution supported will be lower than the DisplayPort and also it will be a lot slower. Playing games or editing video/animation might not work well on the adapters as cheap as you want.

Screens list and thunderbolt external displays

I'm on Mac os 10.7.2 with a macbook pro and an external monitor connected via thunderbolt.
When I try to get a list of the screen with the Screen.screens I only get 1 display, which is the monitor from my macbook. The external monitor doesn't appear at all.
Is this a bug?
I'm compiling in Air 2.7 from Flash CS5.5

I would love to know the same.

Dual External Displays?

Is there anyway to get dual external LCD's working with the macbook? If so please let me know, thanks.

Sort of
Not really but here is a device that will simulate that

Spaces and an external display

I've had a search around and i can't find a way of doing this, maybe someone else has worked it out....
I have a shiny new external display and i'd like to assign a particular space to it - is this possible? otherwise all i end up with is a duplicate of what i have on my MB Pro screen or I have to disable spaces.
any clues fellow mac fans?

This is what I found works for me. Some programs work fine for this method others don't. I first go in and set all the apps in spaces preferences to the corresponding space they belong to. This gets them to the basic location I want. I usually use two apps together on the two screens such as Bridge and photoshop. Open the application you want to use on the external monitor. It should open on the correct space assigned to it initially.
Now you choose the spaces icon on the dock. This brings up all your spaces with the corresponding external monitor space next to it. Drag the application from the internal space screen to the external space screen. Now choose the app you just moved. This will take you to the correct space and app window. Close the app. When you open the app again it should open with its window in the external monitor. The applications menu bar stays on the main monitor but the window is where you placed it.
As I said this works for most apps but not all. You will find out which ones don't quickly. Then just open them and once you get to the app window drag it over to your external display.
I usually start all my apps I will be working on and arrange them like I want fixing the ones that don't start on the correct display. Then it is easy to change spaces and have my work area ready to go.
One thing I discovered in Pages is if I close a file that is displayed on the external monitor the same file when opened again will show up on that monitor. Comes in handy if you work on multiple documents. You just save the file on the window you want it to appear in the next time you need it.

Why doesn't my MBP recognize my DVI external display?

After using my MBP and 30" Dell 3008WFP monitor for about 2 years... the system quit recognizing the display.
No dropping the MBP, no software updates, no unusual activity, no cable changes... nothing. One day it works the next it doesn't.
I've read so many blogs earlier today with people fixating on cables and adapters, but I'm not sure they have much to do with this one... because nothing has changed in my experience, but the MBP no longer detects the display and the display no longer detects the MBP?
I've tried changing eerything, but no luck. Can anyone help me sort this out? Thanks in advance for your replies...

You need to set them up via 'system preferences'.
On your pop up screen go to preferences and then to print&fax
From there use the + button to add a printer of your choice...
Be aware that some printers do not have automatic drivers for mac and therefore you may need to get that from the internet... unfortunately most makers treat Windows as priority still!
I have a very expensive pair of printers in my office the B&W works and the Colour cannot use a Mac driver, go figure!

I have a Macbook and an external display that will not connect.

I bought a Mini DisplayPort to VGA adaptor from Apple but the Detect Displays under system set up does not recognize my external display. The Mini Display port doesn't fit into the port on my Macbook with the Display printed above it but into "Y" port. The picture on the package for the adaptor matches the ends of the adaptor, but they don't seem to fit where they should.
Is that the issue or is there something else?

Thank you. I didn't know where to look for that information.

Dual external displays but different resolutions--why?

I have a 2014 MacBook Pro Retina. I have two identical HP Pavilion 22bw monitors attached via the display ports. One has satisfactory resolution, one does not. They display the same settings. I do not understand why one looks so different.

Hi joegage,
I'm sorry to hear you are having issues with one of your external displays. If they are identical monitors with identical settings, you may find the troubleshooting steps outlined in the following article helpful in isolating the issue:
