Triple display. no mirroring. imac 3 monitors. possible?

I am wanting to add a third VGA display to a media-purpose imac at my business.
—example:
(external 1) (internal) (external 2)
i do not want to mirror the third display.
1. is this possible?
2. what is the best way to accomplish it (what adapters/devices do i need)?
I already have a miniDisplay to VGA for the current external display.
I have looked at VGA splitters, but they only seem to support mirroring (external 1) and (external 2).
All help appreciated.

Linking display to mirror on second monitor

I have a new Macbook Pro.
I give talks and want to use another larger LCD monitor on a stand to display the images of my talk.
I did this with my previous Sony laptop but I am not having success with the Macbk.
I have an Apple adapter to connect the laptop to the monitor and it displays the screensaver which is showing on the laptop.
It does not show the desktop nor anything else.
How do I get the monitor to show the same as the laptop?
Cheers and thanks.

Many thanks that worked.
I,ve written it down so I don't forget.

Is is possible to Triple Display from the New MacMini

Is it possible to run a triple display on a MacMini with the intel HD 4000 chipset (which according to Intel is triple monitor capable).
I would assume one display would run off the HDMI and the other two from the Thunderbolt Port.
If it is possible three displays, is it possible to daisy chain two MiniDisplayport monitors from the Thunderbolt port. I know it will run one MiniDP but am unsure if it will run 2.

You can use a splitter for one output but yo have top mirror those displays.
You need a USB video adopter like this one to add a third independent monitor

Mac Pro 2008 with Radeon 4870 video useable resolution on DVI limited to size of minidisplay port VGA when displays are mirrored. Did not have this problem until I plugged in new monitor (miniDisplayport), but now it affects even going back original mon

Have been using the Mac Pro since 2008. Changed to a Radeon 4870 card early this year. Everything was fine.
Running an old KDS monitor from minidisplay port to VGA and a 1400x1050 projector from DVI out. Have used the
two mirrored the entire time with no trouble.
The old kDS monitor looked like it was starting to go bad so I got another monitor. Don't have much room
so it's a 14inchwith widescreen 1328x768 display. Hooked that to minidisplay port as it only has a VGA input.
Immediately the LCD display took over and restricted the output to the projector.
If I turn off mirroring, I can get projector back to normal. But this makes running programs a lot more difficult.
It worked fine with mirroring on before the monitor change. Except going back to old monitor,
now it is affecting things. I pull up display preferences. If the displays are mirrored, even setting the projector
to 1400x1050, it says "usuable resolution 1280x1024." It didn't use to do this at all.
Tried reseting NVRAM - no result.
Any suggestions would be helpful. Just looking at the image on the projector, I don't see any difference from
before.

UPDATE:
As noted in the first post, both of these newer USB DAC work fine at 24/96 on my wife's iMac, so it's clear that they didn't both become defective when I connected them to the Macbook Pro at the same time.
Resetting the Macbook Pro PRAM didn't help, so I removed the hard shell laptop case to get to the battery and remove it, then reset the SMC. After that I could use the original DAC at 24/96 again, but only IF it was plugged into the rear USB port. If I plugged it into the front USB port then the sound was garbled and filled with noise. This was a vast improvement over no sound at all.
Then I switched to the replacement/updated DAC, but I got no sound at all from either USB port at any bit-rate. And returning to the original DAC again now results in no sound again.
Sigh... I will reset the PRAM and SMC again, and see how far I can get with this. I'd still love some help. Thanks!

27" iMac Powers Up - Black Display - Able To Use External Monitor

I have a strange problem, but I believe it's a software problem and maybe could get some help here before lugging it over to the apple store for the second time in 3 months.
- Today when I turned on my 2010 27" iMac it booted up, gave me the start up sound, my external hard drive turned on, fans were going, but the monitor remained off which never happens. The night before I hadn't done anything out of the ordinary like changing settings or installing anything.
- I tried turning up the brightness on the keyboard and that didn't work.
- I shined a flashlight into the screen to see if I could see a faint desktop as if the backlight had gone out, but saw nothing.
- I turned on my external Acer monitor and to my surprise my entire desktop was on that external monitor which I've never seen happen. It's almost like the computer knew the screen was dead and shifted everything over onto that monitor.
HERE'S WHERE IT GETS WEIRD....
- I put the computer to sleep. When I went to awake it from sleep I turned on the external monitor and to my surpise the iMac screen turned on as well, but my desktop was still located on the external monitor. It remains on. It doesn't flicker or turn off after 10 minutes, it remains on.
- I turned off the computer and did an SMC restart which I know is mostly BS for any of the other times I've had problems with the iMac. I figured it would not work and it didn't.
- I can get the iMac screen to come on, but ONLY after it wakes up from sleep, but it's still situating everything on the external monitor. It's as if the iMac is treating it's own screen as an external monitor.
So it's not that my graphics card is dead or my backlight burned out. It's just a matter of telling the computer to turn on the display.
If anyone can help me out I would greatly appreciate it!
- Joe

Tried to Safe Boot, didn't work.
Did one PRAM reset it didn't work. I'll try your suggestion of 3 in a row and see if that works.
I have a temporary solution on how to get the iMac display to work after freak luck:
1) Turn the computer on from being shut down. iMac display is dead. Ext. monitor works with my desktop on it.
2) Put the computer to sleep.
3) Wake the computer up from sleep, but make sure the external monitor is turned off. The iMac's monitor turns on, but the iMacs monitor is treated as an external monitor with nothing on it. I can only slide things over from the external monitor onto the iMac screen.
4) Restart the computer
5) Desktop and everything goes back and gets situated on the iMac display.
I can put it to sleep, but once I shut it down I have to start all over again. At this point my guess is a boot up issue. Because after the iMac screen does turn on from sleep and I restart it everything works fine. It's just getting the screen to come on when it boots up from shut down is the problem.
I will most likely be taking the iMac to the Apple Store. In some misplaced, weird way I get a kick out of it because everytime I bring a problem to them, they've never seen such a problem before, so with my luck they've probably never seen this before.
Thanks again for your help BDAqua!

IMac triple display

I have an iMac G5 and 2 old(ish) LCD monitors and I want to hook all three up to make to have the iMac be the center monitor and one of the LCDs on each side. Now the standard DVI port doesn't plug into the iMac because the iMac only takes mini DVI. So what I was thinking was:
1. Take a mini DVI to DVI converter plugged into the iMac.
2. Have a DVI splitter converting the DVI output from the converter into two ports.
3. Plug one of the LCDs into each port
Thanks

There is no official way to do that with an iMac G5. There is a hack that enables screen spanning on Macs where that capability exists in hardware but was not enabled by Apple.
http://rutemoeller.com/mp/ibook/ibook_e.html
If you click on the link that shows supported Macs, the G5 iMacs are listed. However, this is unsupported and the description says nothing about it being compatible with Leopard.
Also, there is no way to connect TWO external displays to an iMac. Well, there is a way, but one of those two display will have to a fully functioning computer. Then you can use VNC and this clever program to add a another display.

I'm suffering from a reconnection problem which impacts my ability to use mirroring of my Macbook Air display on my iMac display. Both are using Yosemite OS and sharing the same bluetooth peripherals via the iMac. This did not happen much before Yosemite but I get a Reconnecting display about once every 15-20 minutes now when I am accessing my macbook in a session. Connection to the Macbook Air via a Thunderbolt cable also seems a little flaky, may or may not connect. Often improved by opening (waking) up the macbook if no response. Occasionally I get a Failed to Authenticate Macbook Air error which appears to be a hard error, typically after not having been using the laptop for sometime, e.g. overnight!

Yes but there's no point doing it here. As the Terms of Use make quite clear this is a User to User forum. It's Users like you talking to other Users. It's not a channel to communicate with Apple.

Using a 27" iMac as Monitor for PC

I am building a PC for Network Attached Storage (NAS) using FreeNAS:
http://www.freenas.org/
Once it's all set up I'll just use the web/network interface to manage it. But, as I assemble the PC I'll probably need a monitor to make changes to the BIOS settings.
I'm wondering whether I can use my iMac (iMac11,3) as a makeshift monitor for the PC. Apparently it's possible to do this if the PC has a Mini DisplayPort.
http://support.apple.com/kb/HT3924
My PC has the followoing video ports:
- VGA
- DVI
- HDMI
Can anyone tell me whether I can use my iMac as monitor to a PC with one of these ports?
If so, can anyone recommend a cable to do so? For example, this Mini DisplayPort <-> HDMI cable says it won't work for my purposes:
http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10428&cs_id=1042802 &p_id=5311&seq=1&format=2
"This device is not Bidirectional. It can only connect a Mini-DisplayPort source to an HDMI® display. It will not work in reverse."
I want to display my PC's VGA, HDMI, or DVI as the source to my iMac's Mini-DisplayPort, not the other way around.
Thank you for your help.

But that one doesn't support the 27" screen, you need Dual-Link DVI if it's going to work at all...
Note: This product supports single-link DVI. Dual-link DVI and the Apple 27" Cinema Display are supported by the GTV-DVIDL-2-MDP.
Which is even more money...

Problems Setting up triple Display

Hi Folks, after some help
Recently tried setting up a triple display set up on Mac pro with ATI Radeon HD 5770 from the single display previously used.
I have 2 new Samsung B1930 monitors connected through Mini Display Port to VGA apple connectors in the 2 Slots and my old Samsung B2430 connected up through the DVI.
What i hoped to achieve is
Left B1930 extended desktop
Middle: B2430 Main screen with Dock etc
Right B1930 Extended Screen
What i have is the left B1930 as the main screen (inc Dock) and the Middle B2430 and righ B1930 as the extension. Is it only possible to extend one way? or is there a way to extend left and right.
Cheers in advance

Ignore, completely thick user! Put your glasses on and Drag the white bar. Does blaming a small 19" monitor help

IMac as monitor for MBA

I have a mid 2012 MBA and and early 2009 iMac. Is it possible to connect the iMac (it does not have Thunderbolt) as a display for the MBA? I know that I can hook an external VGA monitor to the MBA (am actually using an old 15") but would like to take advantage of the iMac screen if possible. Apparently the MBA can be connected to an iMac that has a Thunderbolt port, but mine does not.
Ben F

Yes, you need a MiniDisplay port to MiniDisplay port cable. The cable will plug into the Thunderbolt port of the air.
Press CMD F2 on the iMac and it will enter Target Display mode for the MBair.
Edit: I have the same combination with a 2011 Thunderbolt MBair and 2009 iMac. It works.

27" iMac as monitor for Lenovo T400 laptop (VGA out)

I thought I read that it would be possible to use the iMac as an external display. I bought a cheap cable that is Mini-DisplayPort (M) to VGA (F), and I also bought a VGA cable (M-M). I plugged the cables into each other, then into the iMac, then into the Lenovo T400 laptop I have to use for work.
The iMac didn't react at first, then, when I pressed cmd-F2, the display on the iMac changed resolutions to something like 640x480, but was still displaying the Mac. I looked at the Display control panel on the Lenovo and it could see that a monitor was plugged in, and could see what size/resolution it was. However, even when I clicked "extend desktop onto this display", it still didn't display anything from the PC onto the iMac screen.
All went back to normal when I unplugged the cables.
Thoughts?
Sure, it could be the cable(s), but I was intrigued that the Windows Display Control Panel could see that there was a monitor there.

Brent D. wrote:
I read that. It says, among other things "using a Mini DisplayPort to Mini DisplayPort cable or using a converter that converts other electrical, video, and audio protocols from another source device to Mini DisplayPort compliant signals. (Cables and converters available separately.)"
A 'simple' VGA to Mini DisplayPort adapter is not sufficient to provide "+Mini DisplayPort compliant signals+" as mentioned in that article.
For that you would need an Analog-To-Digital converter and those are ranging in about USD 200 or more.
Are you saying that the Mini DisplayPort adaptors that go from Mini DisplayPort to VGA, which I bought, only go from Mac to VGA monitor, rather than in both directions?
Yes, that's exactly the point (see above).

T420 - Triple display not working

So, according to this page: http://www-307.ibm.com/pc/support/site.wss/MIGR-76617.html , the T420 I have is supposed to support two external displays as well as the laptop display as follows:
ThinkPad-only Triple Display Configuration:
1st Display: Active ThinkPad display
2nd Display: VGA analog monitor attached to the ThinkPad VGA analog port.
3rd Display: DisplayPort monitor attached to the ThinkPad DisplayPort
However, when I connect both external displays, it will switch off one of the external monitors (the first one connected).
Using display port to HDMI cable for monitor 1, VGA for monitor 2. Both are verified working as external monitors with the T420, just not at the same time.
I've looked through the BIOS and display properties to no avail.
Is this actually possible without a docking station?
-B

Only a laptop with a discrete NVIDIA graphics card, will support those configurations. If you just have the onboard Intel graphics, then I bet you'll only be able to drive two without a dock. With a dock, you still may be able to drive three monitors (including the ThinkPad's LCD).
BTW, I found even with an NVIDIA discrete graphics option, that page you refer to is incorrect (else I have a problem with my docking station). It says you can drive three monitors with "Any combination of the following" when after much trial and error, I determiend one has to be a VGA analog connection.

Using iMac as Monitor

How do I use the 2011 iMac as a monitor for a MBP? The 2011 iMac does not have a mini display port. Alternatively, how would I connect my LED Cinema Display to the iMac as a second monitor? The monitor has the mini DVI cable built right into the monitor (along with the power and USB cables).

A brand new customized 27". It can be used as a monitor, but only with a product that also has a Thunderbolt port. It no longer has the MiniDisplay port and although the MiniDisplay cable fits it is not completely compatible (that I expected—I was actually surprised that it was compatible in any way). They didn't have MiniDisplay to MiniDisplay cables (that is when the sales person went and asked for help and the Apple Genius stepped in). I was so tired with it at that point that I did not ask how they do it at the store—actually, I have not seen an iMac hooked up to anything else through Thunderbolt. The sales person mentioned that there is only the one cable available (Thunderbolt to Thunderbolt) and a new hard drive.
I'm hoping I'm not stuck with some cutting edge technology that won' take off, and
I'm a bit mystified that three people (the business account representative, today's sales person and manager) were not trained/up-to-date about this.

Is there a way to keep my 2nd, iMac connected monitor, from timing out?

I own A 27" iMac that was purchased in late 2012. For the most part, I love this machine.
The one thing that is a total drag, is that when I connected an Apple 30 inch Cinema Display to my iMac, using Apple's Mini DisplayPort to Dual-Link DVI Adapter, I got all kinds of noise and articfacts that Apple tech support was not able to resolve.
So I brought a similar product to the dual link adapter (suggested by Apple), that was made by another company. To my delight, the noise and artifacts completely went away. Another problem occurred, however. The Cinema Display now times out if I'm not working. To wake up the monitor, I have to dig behind my iMac and unplug the display port USB from the back of my iMac, to get the Cinema Dispaly to wake up. Sometimes I find myself doing this eight times a day, which is getting old.
Any ideas on a resolution would be greatly appreciated.
Thanks!
Will

Keywords, sometimes called tags, are words assigned to a photo based on the content - so, you could tag all your kids photos with their names, all the birthday shots with 'birthday' so to find all the shots of John's eighth birthday it would be
Smart Album
Keyword is John
Keyword is birthday
Year is whatver...
Some ideas about organising in iPhoto:
I use Events simply as big buckets of Photos: Spring 08, July - Nov 06 are typical Events in my Library. I use keywords and Smart Albums extensively. I title the pics broadly.
I keyword on a
Who
What
Where basis (The When is in the photos's Exif metadata). I also rate the pics on a 1 - 5 star basis.
Using this system I can find pretty much find any pic in my 40k library in a couple of seconds.
So, for example, I have a batch of pics titled 'Seattle 08' and a typical keywording might include: John, Anne, Landscape, mountain, trees, snow. With a rating included it's so very easy to find the best pics we took at Mount Rainier.
File -> New Smart Album
set it to 'All"
title contains Seattle
keyword is mountain
keyword is snow
rating is 5 stars
Or, want a chronological album of John from birth to today?
New Smart Album
Keyword is John
Set the View options to Sort By Date Ascending
Want only the best pics?
add Rating is greater than 4 stars
The best thing about this system is that it's dynamic. If I add 50 more pics of John to the Library tomorrow, as I keyword and rate them they are added to the Smart Album.
In the end, organisation is about finding the pics. The point is to make locating that pic or batch of pics findable fast. This system works for me.

How do i set up a second display for my iMac desktop? I want to use both displays at the same time.

how do i set up a second display for my iMac desktop? I want to use both displays at the same time. My iMac is the 24" Late 2006 model. I recall that there is a cord for plugging in a second monitor, but I want to make sure that i can use both monitors side-by-side at the same time. thank you.

If the Display supports DVI, then you will need a > Mini-DVI to DVI Adapter and a DVI cable.
If the Display only supports VGA, then you wiil need a > Mini DVI to VGA Adapter and a VGA cable.
Noting that the (digital) DVI is far better than the (analog) VGA connection.
