HT3382 With a MacbookAir (mid-2012) using a mini DisplayPort to VGA adapter plugged into the Thunderbolt port, can you configure the external monitor to FULLY display in portrait mode yet keep the built-in display in landscape mode?

With an 11"-inch Macbook Air (mid-2012) using a mini DisplayPort-to-VGA adapter plugged into the Thunderbolt port:
Can you configure an extended desktop with an external monitor (20") displaying full portrait mode (1200 x 1600 resolution) and keep the built-in display in landscape?
I'd like to see something like
External monitor / Built-in display

Yes, I can't see why not.
Just give it a try and report back if you have a problem.

My MacBook screen is stuck in "presentation" mode after using my "Mini DisplayPort to VGA Adapter." How can I fix this?

My MacBook screen is stuck in "presentation" mode (I don't know the correct term) after using my Apple Mini DisplayPort to VGA Adapter - meaning the screen fonts and windows are larger than usual. How can I fix this? I've changed the display settings to modify it a little, but it still doesn't look right. I reinserted the adapter numerous times and restarted my computer, it still hasn't worked. Help!

No image on screen using Mini DisplayPort to VGA Adapter

Received mini today. After unboxing, read through the packet. Then began to hook everything up as directed. I used a Mini DisplayPort to VGA Adapter to connect the monitor from our now dead desktop to the mini. After double checking all connections, I hit the power button. I immediately heard the apple chime. Then the monitor showed the grey apple start up screen. Suddenly the monitor went black and said it was going into sleep mode. I can't get it out of sleep mode when connected to the mini. It is NOT the monitor or the adapter. I plugged the monitor straight into a netbook and it worked. Then, I plugged the monitor using the adapter into my MacBook Pro and also got it to work that way. So I tried replugging the adapter into the mini. Still can't get an image on the screen. I can't complete set up or use mini because I can't get an image. Any suggestions or ideas? I will call apple in the morning if I can't figure it out tonight. But I'm hoping someone can give me suggestions. Thanks for your help!

I had the same issue when I bought my mac mini last week apart from I wasn't even getting the initial grey screen. I went back to the Apple shop and they gave me another mini and fired it up in the shop using the adaptor on an old VGA monitor. It worked perfectly.
When I got home I set it all up again and still had the same issue. I nearly threw out a couple of monitors as I thought they were broken.
However, had a look around the web and found this suggestion:
Shut down the mac and disconnect the adaptor from it. Now fire the mac up and let it boot up FULLY. Once it has had a chance to boot up fully, only then plug the adaptor in.
Worked for me and I haven't had the issue since (touch wood). Hope this helps.

Does the "Mini DisplayPort to VGA Adapter" work with all Samsung tv models?

Does the "Mini DisplayPort to VGA Adapter" work with all Samsung tv models?

It's a VGA adapter. Nothing special about that. If your Samsung monitor supports VGA then it will work.
But why not go completely digital and use a Mini DisplayPort to HDMI adapter to skip the analog conversion? It also supports passing audio over HDMI.

Using Mini DisplayPort to VGA Adapter to connect Macbook Pro (2009) for a presentation via projector.

When I connect my Macbook Pro (2009 model) using a Mini DisplayPort to VGA adapter to display a presentation via projector, only the top-left portion of what is displayed on my Macbook Pro's screen is displayed on the projector, as though I zoomed in on that portion of my screen. The projector is on and the adapter and the cable that connects the adapter to the projector machine is correctly connected. Any suggestions on how to fix this problem?

Hi glraczon.support,
It sounds like the external display you are using (projector) operates at a smaller resolution than your MacBook Pro. You may want to configure the display preferences in System Preferences for the external projector.

I have a MBPro mid 2013 with 1 Thunderbolt port. Just bought a Mac monitor and want to daisy chain a PC monitor to it. Use a Mini DVI to VGA adapter from MBP to PC monitor. How do I daisy chain the 2 monitors?

Hall Palm Desert,
if your Mac monitor has Thunderbolt ports, and the PC monitor is on the end of the daisy chain, then you might be able to do it by connecting your PC monitor’s VGA cable to a Mini DisplayPort-to-VGA adapter (e.g. Apple, NewerTech), connecting that cable’s Mini DisplayPort end to one of the Mac monitor’s Thunderbolt ports, and then connecting a Thunderbolt cable between the other port on the Mac monitor and your MacBook Pro.

Thunderbolt display: devices not discovered after using Mini DisplayPort–to–VGA adapter

I have an interested problem related to using my MacBook Air in clamshell (closed) mode, connected to a Thunderbolt display. The problem appears to be related to moving my MacBook air between my office and my home.
At the office, I use the MacBook Air with an external VGA display, connected via the Mini DisplayPort–to–VGA adapter. At home, I use the MacBook Air together with a Thunderbolt display. An Apple USB keyboard is also connected to the display.
Mini DisplayPort–to–VGA adapter implicated
The following sequence of events causes the problem to occur:
Use the MacBook air (open) together with a VGA display, connected via a Mini DisplayPort–to–VGA adapter (depicted at right);
Put the MacBook Air to sleep by closing the lid, and disconnect the Mini DisplayPort–to–VGA adapter (I am not sure if the order of these two steps is significant—I usually perform them almost simultaneously when packing up my MacBook Air and getting ready to leave the office); and
With the MacBook Air still closed, connect it to a Thunderbolt display with a connected USB keyboard.
At this point, I would expect to be able to wake up the MacBook Air by tapping on the space bar of the keyboard. However, what I have observed is that this does not wake the MacBook Air.
I can wake the MacBook however by moving or clicking a Bluetooth mouse that is paired with the MacBook Air.
At this point, although the MacBook Air is awake, and the display is working, the USB keyboard connected to the display still does not work. This is the problem, in a nutshell.
Unplugging the USB keyboard from the display, and plugging it back in causes the MacBook Air properly to identify the keyboard.
I used Apple System Profiler to save a list of identified devices at two points in time:
Immediately after waking the MacBook Air by moving the Bluetooth mouse (at which point the USB keyboard was not working); and
After unplugging and plugging in again the USB keyboard (at which point the USB keyboard worked fine).
Many devices are enumerated in the second list that are missing from the first. For example:
Keyboard Hub@fe110000 <class IOUSBHubDevice, id 0x1000378ef, !registered, !matched, inactive, busy 3 (37993 ms), retain 6>
AppleUSBHub <class AppleUSBHub, id 0x1000378f2, !registered, !matched, inactive, busy 1 (37987 ms), retain 6>
IOUSBInterface@0 <class IOUSBInterface, id 0x1000378f4, !registered, !matched, inactive, busy 1 (37986 ms), retain 6>
Keyboard Hub@fe110000 <class IOUSBHubDevice, id 0x1000378f6, registered, matched, active, busy 0 (7 ms), retain 10>
AppleUSBHub <class AppleUSBHub, id 0x1000378f9, registered, matched, active, busy 0 (1 ms), retain 9>
IOUSBInterface@0 <class IOUSBInterface, id 0x1000378fb, !registered, !matched, active, busy 0, retain 7>
Apple Keyboard@fe112000 <class IOUSBDevice, id 0x1000378fd, registered, matched, active, busy 0 (112 ms), retain 11>
and many child devices…
Using the Mini DisplayPort–to–VGA adapter appears to be a necessary step to causing this problem to occur. If I merely disconnect the MacBook Air from the display, let it go to sleep, and then reconnect it again, the USB keyboard will work immediately and can be used to wake the computer from sleep.
Some devices are discovered even when the computer is in sleep mode. This is how it should work.
The problem appears to be that when a Mini DisplayPort–to–VGA adapter has been used since the last time the computer was connected to a Thunderbolt display, the MacBook air does not discover devices completely when it is again connected to the Thunderbolt display while in sleep mode.
Can anyone else reproduce this problem?

Using Mini DisplayPort to VGA adapter -- any settings on the Macbook Air I need to change?

Connect two external monitors to mini DP(using a mini DP to VGA adapter) and the VGA out at once

I am trying to connect two external monitors to mini DP(using a mini DP to VGA adapter) and the VGA out at once. Windows recognize both monitors as well. But it dowsn't let me use all three monitors at once(see the below image). In the dropdown, it lists all three monitors. Problem is there are two active displays I can select.

I would like to add a third monitor.
The GPU(s) in your T400 (and most other laptop brands) will support two different displays concurrently. If you want to support more than two different displays concurrently, you will need another GPU external to the T400.
Generally, if you want to use two external displays on a T400 you will nee dto use a docking station.
I have read messages on various fora on this topic and know that there are a number of ways of doing this, but as I have never had a need to do this myself I can't tell you how to go about it.

Mini DisplayPort to VGA Adapter NOT DISPLAYING ON EXTERNAL SCREEN

Hello!
Mid 2012 MacBook Pro
Processor 2.9 GHz Intel Core i7
Memory 8 GB 1600 MHz DDR3
Graphics Intel HD Graphics 4000
Software OS X 10.9.3 (13D65)
I have a mid 2012 MacBook Pro, I have connected a Mini DisplayPort to VGA Adapter in order to watch movies on a HP w19e LCD display.
Ive been using this adapter for a year now and I have never had any problems with it, until now...whenever I connect it to my mac's display turns black, and nothing happens, so I wait and the LCD display shows the unfurtunate NO SIGNAL message, so I wait a little longer and still nothing happens, I unplug the Mini DisplayPort and plug it back in, and nothing happens, and when I say nothing happens I mean nothing happens, my mac's display is black as if it was in sleep mode, I get no signal on the HP LCD and I can't get my computer's display to show image again, the only way to do it is to force restart it.
I looked up the problem and I found a forum with a possible solution for it and did as it said.
1) Restart the computer in Safe Mode with display attached (shut down and restart while holding down shift key).
The display showed up without distortion.
2) Change the display to my desired preferences (dimensions and refresh rate).
3) Restart computer. ...and it works like a charm.
I followed the directions and it worked... but after I restar to go back to um.. normal mode, the problem is back.
Please I need my LCD screen how can I fix this.
I hope I didn't confuse anyone, sorry for my english

I'm having the same problem. When I try to connect to the switch in our conference room (connecting both a flat panel display and/or a projector, both with much higher native resolutions), all I get is 640x480. This is a huge problem to using bootcamp, and I really need to get this to work. I was able to get a higher resolution 1280x800 on a separate, portable display, so I'm wondering if people have the problem with standalone projectors or only with projectors connected to some sort of switch, in my case an Extron MPX423A. I have also tried this in both Windows Vista (32-bit) and Windows 7 RC1 (32-bit), with the bootcamp drivers and the latest NVidia drivers, and the behavior is the same all around.

Getting a Mini DisplayPort to VGA Adapter & Monitor to Work with an Xserve

First let me say that I'm very new to Xserve's and OS X Server and any help is greatly appreciated.
I have an Xserve with a connected Mini DisplayPort to VGA Adapter and a confirmed working VGA monitor. There is also a keyboard and mouse plugged into the front USB port of the Xserve. The internal SSD has been formatted clean.
I've been trying to boot up from the optical drive on the Xserve using the 10.6 DVD. I use the front panel/system identifier button to boot up and I make sure enclosure lock is unlocked. Each time I try to boot up, the monitor stays off and the DVD is spit out.
I eventually got the DVD to stay in, and the screen showed the grey screen with black apple and the spinning black circle on the bottom. However, after a few minutes the screen turned orange in color. Using Screen Sharing, it looked fine. I tried a second VGA monitor, but that still didn't do it.
So with the DVD still in, I stay connected via Screen Sharing and begin the installation process remotely, thinking Snow Leopard will recognize the monitor eventually. Well, 10.6 is now fully installed, but still no working monitor.
I then decided to try the Mini DisplayPort to VGA Firmware Update. I download and run the installer, but it tells me, "The Updater could not find a Mini DisplayPort to VGA Adapter to update."
How can I possibly get this monitor working?
Thanks in advance.

Just ran in to this myself -- Nehalem Xserve running 10.6.2 Server with an MiniDisplayPort to VGA adapter connected to an Avocent Switchview 1000 KVM. Took the server offline to install RAM and after rebooting, no video. Oddly enough, the KVM's LEDs showed a display connected but Apple System Profiler showed no adapters connected to the video card. Nothing seemingly worked -- rebooting, shutdown/restart, and/or hot-plugging the adapter made no difference. I also tried a second MiniDisplayPort adapter to no avail.
Note that the MiniDisplayPort to VGA Firmware update had already been applied to BOTH adapters prior to this issue appearing.
What restored video output on our system: reboot from the Snow Leopard Server install media, video reappears over the adapter, and after that I can reboot from the SSD boot drive running 10.6.2 Server with video output working over the MiniDisplayPort to VGA adapter.

How long can the Mini DisplayPort to VGA Adapter last?

Hi,
I've been using Mini DisplayPort to VGA Adapter (genuine) for a year now but not everyday. Yesterday I bought a new display that needs this adapter, so now is the time that it will be used everyday. I was wondering how long can it last (or operational hours) if it were to sit in the same place, not unplugged, with an average use of 4 hours a day?
Thanks
PS. This one: http://store.apple.com/us/product/MB572Z/B/mini-displayport-to-vga-adapter.

This is impossible to predict.
Sometime cables last a lifetime, sometimes they fail in short order.
