Dual 27" iMacs - one as a monitor?

This may sound like a stupid question, but I want to be sure before I go buying a cable. I am in a unique situation...I just got clearance to work from home at my job (as a graphic designer), and I bought a 27" iMac Core i5. Well, work also got new 27" Core i5 iMacs for us, so because I am working from home, this means I'll have DUAL 27" iMacs
There is plenty of info on the web about connecting a Macbook to the 27" iMac, but nothing about connecting ANOTHER 27" iMac to each other
My question is, would it be possible to connect one to the other during the work day and use target display - in essence, giving me a dual 27" desktop, with a 5120 x 2880 resolution! I know iMacs support video in, so would I be able to by a mini displayport to mini displayport cable like this one for it?

Hey thanks - that's a good call. I found the answer I think...it just took putting the right sequence and combo of keywords in to Google
_#2 here says:_
Connect a male-to-male Mini DisplayPort cable to the Mini DisplayPort on each computer. The 27-inch iMac will enter Target Display mode and display content from the source computer.
*Note: If you are connecting two 27-inch iMacs, connect a Mini DisplayPort cable to each computer and press Command + F2 on the 27-inch iMac keyboard that you will use as an external display.*

I'm trying to set up a dual monitor for my new iMac. I'm using a second display I used with my old G5. My iMac recognizes the second monitor but the monitor won't turn on. Power button doesn't do anything on the monitor itself.

I'm trying to set up a dual monitor for my new iMac. I'm using a second display I used with my old G5. My iMac recognizes the second monitor but the monitor won't turn on. Power button doesn't do anything on the monitor itself.

If it won't turn on then the monitor is dead (power supply?, video circuits?). Not worth repairing.
If you have a new iMac then it has thunderbolt. So exactly what is that monitor you are trying to connect? For TB you can connect a mini-displayport monitor. Probably (not 100% sure with TB) can use dvi or vga too if you have the appropriate adapter.

Can older dual core iMac be external monitor to new (lion) imac

If yes, how do they need to be connected and configured?

Thanks, classic II for the reply. You are right--I should consider configuring my old Mac to be a wireless device if/when I get a new iMac, however I still would need my flash drive to have embroidery designs on it in order to get the designs into xp under bootcamp.
It was painful for me to get my dual core iMac upgraded to 1 meg for snow leopard. I could drive 50 miles to an authorized apple person, leave my iMac and he would order and install the 2 gig memory and in addition charge me $300 to fix the cd drive that was barely off warranty or do what I did. Local apple store would install a half Meg of memory but couldn't do the ordering. So I ordered 500 meg memory from on line apple store, had it shipped to my house, and then had apple store install it--to get me to 1 Gig, so I could install snow leopard--I think the apple store installed it for no charge since I ordered the memory from on line apple store, and didn't have to drive 50 miles, one way--twice.
What I have is working for me, so I guess I'll just watch what happens with lion and icloudI and apple tv (and bernina v6 software which only runs under windows7 on macs) and move on to new iMac when things are settled.

X-rite eye-one display 2 monitor calibration and new 27' iMac

Hi,
I have been looking at the new 27" iMac to replace a 24" iMac Intel core 2 duo that I purchased last spring. The main problem being that I am a photographer/graphic designer and found out after I purchased this iMac that my x-rite eye-one display 2 monitor calibration system was rendered useless because the monitor brightness was way out of range (too bright) for the calibration software to work correctly.
My question is: Has anyone tried to use the x-rite eye-one display 2 with the new iMac 27" monitor? I understand that they may have fixed the monitor brightness problem, but now the new screen is lit by LED instead of LCD. Has this just presented a NEW problem that makes this color calibration system still useless or does it work despite the fact that the monitor light source has changed?
Thanks in advance for any info you can provide

The x-rite i1 display 2 won't work with any LCD lit panels. I've attended a x-rite training only six weeks ago and the guy explained the issues. So if you want to calibrate any LCD backlit screen, you have to get a more expensive thing -- maybe the Colormunki will do, but for sure the i1Pro will work. It's still a quite expensive upgrade.

Can I use a 21" iMac as an external monitor?

I'm considering getting an iMac or Mac Mini so I can run Xcode.
My budget is low, so I'm considering just getting a Mini and using it with an old VGA/DVI monitor.
However, as the iMac includes a monitor, mouse, and keyboard, it's actually the same price as a Mini with a mouse, keyboard, and monitor.
Plus, the iMacs are more powerful.
I don't intend to do much on it, just Xcode and maybe some gaming. Gaming is not the deciding factor here.
I've been searching for an answer for hours, and all I found were outdated threads.
My question is:
Are 8GB of RAM really necessary for Xcode, and is the quad-core CPU of the iMac needed?
I also read that an iMac can be used as an external display, but only the 27" models.
I am looking at a 21" 2013 model.
I currently use a Windows gaming desktop, and have lots of extra monitors lying around.
Multi-display support is a must for me, and the iMac screen is way better than anything else I have.
Is it possible to use a 21" iMac as an external display for a Windows machine using a DVI/DisplayPort adapter?
I've read in different forums that "it has to be Thunderbolt". "It has to be a 27" not a 21". "It has to be 2010 or older".
Basically:
Can I use an iMac as an external display for my Windows desktop, and can it be the 21" model?
I'm not getting a Mac very soon, so please take your time.
-Thanks a lot,
Nick
BTW: This is my first post, so it's probably horrible.

Hello Nick, A a warm welcome.. great 1st post too!
I'm afraid using the iMac for a PC Monitor is out, unless it might be a newer PC that has a thunderbolt prt & can output Video through TB port. 2009/2010 iMacs can use MDP. But 21.5" iMacs work as well as the 27" ones for either method.
Not sure DVI or even DisplayPort converters work though.
Here's how it's supposed to work...

Mid 2011s & up need Thunderbolt!

Are 8GB of RAM really necessary for Xcode, and is the quad-core CPU of the iMac needed?
Well, problem is twofold, 4 GB is barely enough for the OS & one App, & you can't really upgrade the RAM yourself later.
I'd go for the Quad core, computers always get slower over time!
Might be some 209/2010 options here...

Output iPad video to 27" iMac as an external monitor?

Hi, I was wondering is it possible to Output iPad video to 27" iMac as an external monitor using iPad VGA adaptor?
Thx.

You'd need something to redirect the VGA signal to a DisplayPort connector on the iMac. Your other option is VGA is easily adaptable to S-Video, though its resolution is not as great as VGA and using http://www.elgato.com/ 's hardware for that. A third one is using a Remote Desktop app for the iPad. Several exist.

Dual core iMac- audio

I'd like to hear from some Garageband users who are happy with their new dual core iMac. I am about to buy one, but I would love to hear from some satisfied customers!
(I'm specifially getting the iMac to use Garageband.)
Thanks-
Remulak

I just bought an iMac 17inch, no upgrades, just for garage band. This my first Mac, and I have been looking at them for years, but never bought becuase in the end the PC offered more value and the Mac did not have it all together IMHO.
I really feel like they do have it all now. (congrats Mr. Jobs) The system, programs, and price are near perfect. I am Mac forever!
I am a guitarist, and the program is easy to use and can do a lot. I wanted to use it to quickly record ideas, (not spend all day, setting up, and my inspiration had long passed). It is also great for practice.
I am just plugging a guitar directly in, using a old chord with, the small head phone jack (like for a old walkman) on one end, and a guitar jack on the other end (mine is actually an RCA on that end, but put a guitar jack on that).
I am using the built in speakers
Drum tracks: the loops are easy to edit, once you spend one day reading and playing around with it. Forum is great for this.
Can't be easier, and does not zap my enthusasm to record, like all other methods I have tried over the years.
Hope that helps

One 30" Apple Monitor shared between two Macs with a switcher Possible ?

I have a G5 Dual processor and a new Pro mac. I was thinking of having two 30'' monitors with the new pro but would love to know if its possible to share one of these monitors with the old G5 via some sort of switch box ? - The G5 will be set up as a node for Logic and at odd times as a stand a lone machine so It would be good to have the option of using one of the two monitors . ( I don't have desk space for a third monitor ) -- what's the story ?

Yes. Look for a dual-link DVI switch or KVM, such as

Can I use my 24" iMac as a second monitor for my Mac Pro?

I bought a Mac Pro with the 27" Cinema display and it's great. Now I want to use my old 24" iMac as a second monitor.

@I run a Windows 8.1 - Photoshop CS5 under Parallels on an iMac one year old and both having the latest OS. I use a NIK plugin "VIVEZA" which run fine for years without a problem. Latelt and without a reason, the NIK plugin has gone corrupt, (can not use it more the 2 corrections after a get a black background message that there is not enough memory) and the system stops running and a must restart is required. How do I fix this terrible problem?
If it requires a Photoshop CS5 re-install, (I belief that it may fix the problem) and re-install the two third party plugins (NIK Viveza) and (Onone Perfect Resize) how and where do I get to the proper Adobe upload page to do that.
I have tried to fix this problem by changing the memory allocations, I have spend many hours on it and are very disgusted with it but it needs to be fixed. The current memory settings are;
Ram available = 1588 MB
Range = 873 -1143 MB
Recommended Photoshop usage range = 857 however I have tried every setting to max and in between. Nothing works. Current setting = 1588 (max)
The Photoshop I use is registered, I have product # and order # .

Contact NIK for updated/upgraded versions of their plug-ins. They have been having a lot of issues with their plug-ins.

T530 - Dual boot not displayed on external monitor when docked

Hi,
I just got my new T530, loaded all my applications and data from my T61. The T530 is connected to the 4338 docking station.
I have Win 7 on the internal disk, and Win 8 on the ultrabay disk.
Dual boot works fine when undocked, but when docked and the lid is closed I don't see the dual boot selection on the external monitor and the PC boots into Win 7 (which is my default OS).
When cold or warm booting I also don't see the Thinkpad splash screen.
I did not have this problem with my T61 when docked. There the splash screen and dual boot selection was displayed and I was able to select which OS I want to boot into.
Any ideas whet I can do here?
Thanks

As I came across this it's a matter of the two graphic cards and how they are shared.
The Intel always drives the Laptop-Display and the analogue port, the digitalports at the docking are all driven by the Nvidia Card.
The splashscreen will always be displayed with the intel card and therefore not be visible with the digital ports at the docking.

Can I run 2 monitor with one of the monitor having Full Screen for Elgato Eye TV?

My mac mini has Elgato 'Eye TV' software that runs in 'Full Screen'. I want to keep this setting & also connect another monitor to the macmini & use other Appilications on the other monitor? Can I run 2 monitor with one of the monitor having Full Screen for Elgato Eye TV?
My early 2009 macmini can run Mac OS 10.5, 10.6, 10.7 & 10.8

Yes, run one from HDMI and the other from Thunderbolt/minidisplayport sockets. In EyeTV Preferences check the screen you want for full screen use and make sure your Dock is on the other one.

Imac not recognizing 2nd monitor

On cold startup, why do I always need to unplug and replug thunderbolt mini display to vga adapter for imac to see second monitor ?
Once I do this, the 2nd monitor is recognized. If I restart, 2nd monitor is recognized.
thanks.. I am worried that the port will be compromised with all the unplug/replugs.
Btw... the "detect displays" function doesn't resolve this issue.
thanks for any help!

Hi John,
I really have no idea, but as a test, hold alt key at cold startup, let it set on that screen for maybe a minute or two, then click the startup volume or hit enter... any change?
Also, if you log out & back in does it show up?

I want to use my old iMac G3 as second monitor to my MacBook Pro, how?

I want to use my old iMac G3 as second monitor to my MacBook Pro, how?
Thanks!

You can't really do it in any normal way; that is, using the MacBook's video output port.
You can use this program
http://www.screenrecycler.com/home.html
to make your iMac screen act as a second display, over a network connection. ScreenRecycler runs on your MacBook and creates a virtual second display. It uses the open-source VNC (screen sharing) protocol to serve that second display over the local network. You then run a VNC client program (usually free) on the iMac G3 and display the MacBooks virtual second screen in a window, which you can display full screen. Your iMac then appears to be the MacBook's second screen. You use System Preferences Displays pane to set it up, as you would a real second display.
How well this works depends on your iMac's speed, what Mac OS version it runs, and the speed of the network connection. If you connect the two directly with an Ethernet cable (Cat-5 or better), the network speed should be decently fast (at 100Base-T). If your iMac G3 has Tiger (10.4), you can use this program as the VNC client
http://www.jinx.de/JollysFastVNC.html
(there are free VNC clients for 10.3 and earlier)
However, this solution will never be as fast (in terms of screen refresh rate) as a real display using a real video connection. But you can try it at no cost, to see if it meets your needs.
