Connecting TWO (2) external displays to the MacBook
Hello!
I currently have a 21.5" LG monitor attached externally to my 13" MacBook. It works great.
I've been thinking of adding another monitor to accompany it, but A) I'm not sure if the MacBook can even handle it, and B) I'm not sure what kind of dongle will work.
Anyone done this before and can offer some helping advice?
THANK!
As far as I know, you will need an external device to split the video signal. I have heard of these devices but I don't how well they work. http://www.amazon.com/Matrox-D2G-A2D-IF-DualHead2Go-Digital-Edition/dp/B000QRTHX 8/ref=sr11?ie=UTF8&s=electronics&qid=1268373132&sr=8-1

Using an external display with the macbook air
hi, i wanna know if i can use an external display with the macbook air as the tunderbolt is a bit pricey? i was thinking about buyin a LCD moniter wih a VGA port. many thanks
Yes. You can use VGA DVI or HDMI monitors by buying a Minidisplay port to xxx adapter and the the appropriate cable (vga, dvi or hdmi).
The MiniDisplayport adapter plugs into the Thunderbolt port.

Here's a sample HDMI adapter. All these available in the Apple online store.

I do have a MacBook 13" connected to the Cinema Display and this works fine. As I do also an old iMac which I do not use any more, is there any chance to use this iMac as an additional monitor next to the Cinema Display. I would be great to have both of them running in parallel and bring the iMac to an use again.
Use a product such as ScreenRecycler.

Can I run two external displays off a MacBook?
Hi there.
I would like to run two external 20" Acer (VGA) displays off of my MacBook. I already use one 20" in addition to my MacBook screen but would like to have two full sized screens to work off and would not need the 13" from the MacBook.
The MacBook literature says that only a second monitor is supported but I was hoping there is a way to override the MacBook screen in a two monitor setup and port the display to the third monitor.
Any ideas ??You can have two independent external displays on the workstation macs such as G4, G5 and Mac Pros but not on apple laptops to the best of my knowledge. If you look on that page it shows the Mac Pro then underneath it is the image of two montiors side by side with the shark image going across it. Lower down is a Macbook Pro with one additional monitor next to it.
This is the text which accompanies the image:
"With an all PCI Express architecture, Mac Pro supports a lineup of state-of-the-art graphics cards to ensure a spectacular visual experience. Every Mac Pro supports two displays — including one 30-inch Apple Cinema HD Display — and can be expanded to drive an array of up to eight displays."
Im assuming the up to eight displays refers to the fact that you can add extra graphics cards to the Mac Pro. -
I have a macbook connected to LED cinema display. The display started to flicker. The display turns black for a second or two. Sometimes I restart macbook and display. Sometimes it helps.
same issue, either your wiring or display itself is going bad. for me, it was the display but luckily still under warranty

My Macbook (2009 White) Has had water spilled onto it, it all works apart from the screen. When connected to an external display it works fine, just not on the Macbook itself. Does anyone know how to fix this?
Take it to Apple and ask them to fix the physical damage the water caused.

I have tried everything I can find on line but they all claim that the plug and play works, and they don't for me. I tried the mini dvi to HDMI and a HDMI cord and that was not recognized no matter which unit I rebooted first. I found someone who said that my Macbook might be too old for the HDMI technology so I returned the cords and went to the VGA cord and adaptor.
I tried this first with the HDMI setup:

Then I tried this with the VGA setup:

I contacted Samsung support and they said I needed to set the display settings to external display on the mac. I went to the display settings and moved the icon to my status bar. When I click on search for displays or whatever it says (I'm not at my Mac right now) it does nothing.
What am I missing?I am using MAC OSx 10.5.8 (9L31a) as my operation system. The TV says "No signal. Check connected device's power, cable connection and source selection." Seems to me that that goes in hand with what the Samsung tech said about the Mac needing to be forces to use the external display. But how do I do that?

I got the following message after the crash, it happens a few times a day, my system is the base with 16gb ram late 2013 15" macbook pro retina. it only happens when i am connected to an external display, I do have a converter from vga to displayport. also, i run 4 different browsers in incognito mode as i do web testing and also have about 30 tabs open and excel and a few other apps open, not sure if this is what makes it happen or if it is the external display? it is under warranty, so if you see anything below that may relate to the hardware i can bring it in and get it fixed.

How do I connect an external Display to the new MC814XX/A
I can't find a port for an external display in the NEW Imac 27" Mid 2011 (MC814XX/A)... I'm trying to connect my Cintiq to it. How do I work arround this?
You need an adapter cable that plugs into the Thunderbolt port. The Minidisplay port to HDMI or MDP to DVI will work. Then you plug a HDMI cable (or DVI) into that adapter and the TV.

I am trying to use an external 3g modem made by Huawei model e173s-6 and when I do connect it on my usb port the macbook pro just do not recognize it. I own a 2012 model with mountain lion 10.8.2 . What should I do ?
I still don't know what happened to my test Aperture Library after the update to 3.4...Not only were my previews lost, but so were the original images! Needless to say, I haven't bothered to update the main library on the Mac Pro because I don't want to deal with this level of uncertainty (even with backups in place).

At work i'm connected to the Lan via an adapter and the mini displayport. I want to use my external display at the same time, which use the same mini displayport. Are there any splitters available to use both at the same time? Are there any other alternatives?
Thanks,
