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.
How can I make this work?
I appreciate all you support!
Thanks

By using ScreenRecycler and a network connection.

Can I use My Ibook G4 as a Second Monitor For My Mac Mini G4

Hi
I wonderd if theres any way of being able to use my 14'' Ibook G4 as a second monitor for my Mac Mini G4? I already have a Samsung SyncMaster 913n. Is there any way of doing this by firewire using both monitors, if not what cables would I need?
Thanks

There is a application called Synergy which you may find useful. It allows the keyboard, mouse and clipboard to be shared across computers, and even different operating systems. It's not strictly what you have asked for as each computer still runs it's applications (and operating system) separately, meaning you can not drag windows between the screens, but by allowing you to copy and paste between the computers, and seamlessly slide your mouse and keyboard input between them you may get the effect you desire. Oh, and it is free and open-source, so why not give it a whirl?
You will need to connect the machines with a TCP/IP network, which can be done either with an ethernet patch cable, or alternatively as you suggest, using FireWire - these two articles may assist you in setting that up: IP over FireWire in Panther and Tiger.
As a point of note, a commercial program, MaxiVista allows exactly what you are looking for under Microsoft Windows.
Hope that helps.

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

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.

How can i use my smart TV as a second monitor for my Power mac (2010) via HDMI cable? i've made the connection but no options show in system prefs display.

How can i use my smart TV as a second monitor for my Power mac (2010) via HDMI cable? i've made the connection but no options show in system prefs display.
the computer:Mac Pro, Mac OS X (10.9.5), 2 x 2.66 Ghz 6-Core intel Xeon
the TV: LG Smart tv

The Mac uses a highly-parameterized universal Driver for every display. The parameters are set at certain times when a query is sent to your display. The display MUST answer with its name and capabilities, or the screen stays dark. A TV set that is off or "not paying attention" because it is set to a different port when the query occurs will rarely answer, and so will often remain dark.
You can use tools in the System Report to see whether your display has been detected at all. If it has, the report will look something like this, but its name will appear:
The times when the query is sent are:
• at Startup
• at wake from sleep
• when the Mac-end of the cable is inserted
• when using the Option ( Detect Displays ) button in displays preferences

Can I use my old iMac as a second screen for my new one?

I have an old iMac (about 4-5 years) that I don't use anymore and a new iMac that I just bought a few months ago.
Can I us my old iMac as a second display for my new one? Its a slow computer now, but the screen is nice and big so it would be nice to be able to keep using it like that.
If yes, what cord(s) would I need to make this happen?
If no, is there any disadvantage to using a non-mac screen for a second display? (I'm a graphic designer, so little things like having the color exact on each screen are very important)
Thanks for the help!

Is there any way to do it without lag? Right now it works, but its really annoying to have things so slow on the other screen.
Is there any way to hook them up so they work like an actual dual monitor setup (wired connection with no lag)?

What is the most efficient way to use my 2006ish iMac as a second screen for my MacBook pro?

Hello.
My line of work really requires the use of two screens, and I have a macbook pro from 2010 and a white iMac from 2006, I believe. My editing software lives on my laptop, so I'd like to use my iMac as the second display. I can't seem to find any male mini dvi to male mini displayport cables online, so I have a feeling they don't exist. Should I just get a mini dvi (male) to dvi (female) for the iMac and a (male) dvi to (male) mini displayport for the laptop? Is this going to cause latency if I'm running videos? Help please!

Your iMac (from 2006) does not support Target Display Mode, that functionality only became available in Late 2009 with MiniDisplay Port. Even if you were to find a male-to-male cable the iMac isn't going to accept the video from the MacBook Pro in a method you're hoping to achieve (extended desktop mode). I've use ScreenRecycler and the lag is barely noticeable, I think even calling it "lag" is overkill.
If you need a second monitor for work that is apparently an important accessory, why are they not supplying with a second monitor? Even if you were to find a valid connection solution, it's response time would still be slower than a direct link from the MacBook Pro.

Can I use my Pavilion HP7 as a second monitor for my workstation?

I have a HP Pavilion DV7 with Windows 7 ultimate installed. I want ot use the screen as a second monitor for my desktop workstation, which is where my fligh simulator is installed. (The desktop is a Lenovo and the graphic card allows for 2 HDMI screens)
Can I connect my HP laptop to the desktop machine in such a way as the laptop does nothing except provide a screen for the Lenovo? (If you've ever got serious about flight simulator you'll know how much you need two or even three screens!! )

Hi,
No you can't you can use other monitor as second monitor for your laptop BUT you can't use laptop monitor as second monitor for other machine.

Can I use my old iMac(late2009) as a monitor for my new iMac i.e. dual screens?

I have a iMac late 2009, just purchased this week,but not received a brand new iMac, i want to use both iMacs,the older one as a second screen.
The older one has mini display port, but no thunderbolt.The New one has thunderbolt,USB3 can i connect them together t ouse older iMac as a monitor?

so if thunderbolt is backward compatible,can I use a thunderbolt to Thunderbolt cable , would the data rate be increased if i did this?, Ive seen those available, but mini port to mini port seems to be more difficult to find, I take it that the mini port connection end of the cable is compatible with Thunderbolt. loads of variations of mini port with usb, mini port to firewire etc me

Can I use my new iMac 20" as a monitor for for Power Mac G5?

Actually I want to buy the new iMac 20" computer with the intel and then randomly use the iMac as a monitor display for my Power Mac G5 when I am editing video and then unhook it and use the Imac as a stand alone when I'm not editing video with my Power Mac. Will this work please. Thank You

Hello,
It's not possible to use either the iMac (Flat Panel) (G4) or the new Intel iMacs as displays. The only options would be:
VNC set-up. It's fairly low speed of refresh would probably make this undesirable for your situation: Screen Recycler (link)
A video-in device. A device like Elgato's EyeTV Hybrid (link) would not be of sufficiently high resolution to be any use for video editing.

Can an iMac be used as a monitor for a Mac Pro?

Hi all,
I'm getting nowhere looking in the search, so I'm hoping someone can clear something up for me:
is it possible to use an iMac as a display for a Mac Pro?
I am beginning to think I'd better get a Mac Pro, but I already have an iMac, for which I've been researching getting external storage so I can do Final Cut Studio editing and back up of it all... as someone suggested, might be better in the long run to just get it all in the Mac Pro, and have the option and simplicity to upgrade as and when... but then there's the need for a display for the Mac Pro, which does whack the price up... but if I could use this iMac, what a beautiful monitor...
I thought someone said that Final Cut would not allow another computer to be attached though... is that the case, anyone know?
Thanks for any knowledge and help, much appreciated... I'm learning to not rush into anything, as you learn more the whole picture seems to change!
Cheers, Syd

The current 27-inch iMac can. Other iMac models can't outside of a VNC setup or ScreenRecycler; all such solutions require a standalone monitor for setup and troubleshooting.

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...

How do I use my IMac as a second moniter for my Macbook Pro?

Okay, So I would like to use my IMac as a monitor for my mbp. The IMac is a 2010 model and the Macbook is 2012 (Not the retina).
I'm a music producer and I'm sick of having to switch devices so I just want to keep all my stuff on the macbook but the screens way too small.
What I want to do is use the mbp screen with the mixer section of logic as well as use the IMac as a second moniter with the arrange screen.
Is it possible to do this with an ethernet cable?
if so
How do I do it?
Oh and a question on the side, Is mavericks worth the download?
Thanks!!

You can use the iMac as an external display for your MacBook Pro, always that you have got a 27-inch iMac. See > http://support.apple.com/kb/PH11302
You have to purchase a Mini DisplayPort cable (Ethernet won't work, as this is not designed as a video cable to connect Macs), and then, press Command and F2 keys on the iMac.
If you have got a 21'5-inch iMac, you can use an application like ScreenRecycler, which uses your network to use the iMac as an external screen

How to use an iMac as a second monitor for an iMac

I have two 21.5 inch iMac's (late 2009) and I want to use one as a second monitor for the other. I have a Mini DisplayPort to Mini DisplayPort connector but when I connect it to both computers, nothing happens. I'm not sure if I'm doing something wrong once they're plugged in or if I have the wrong cable all together. Any tips or advice would be much appreciated. Thanks

Not going to work, the ONLY 2009 / 2010 iMacs that supported Target Display Mode were the 27" models, 21.5" models simply will not work. Please read Apple FAQ on TDM and you will see I am correct.
Target Display Mode: Frequently Asked Questions (FAQ)
While Neil is correct, Screen Recycler's performance is not that good so the user experience probably will not be worth it.
