Connecting 2 (21.5" & 27") iMacs and using 21" as second display

Hi, I have 2 imacs (1x27 and 1x21.5), 27 is mid 2010 and 21.5 is late 2009.
Iam trying to find out if I can use 21 as 2nd display off the 27.
I connected them together with mini dv and they default to 21 as primary and 27 as 2nd.
Any help here would be greatly appreciated?
Thanks in advance.

Welcome to Apple Support Communities
Of course not. Late 2009 and Mid 2010 21'5-inch iMacs can't be used for Target Display mode because they aren't compatible. See > http://support.apple.com/kb/PH11302
It means that you can't use your old 21'5-inch iMac as an external display wired, but you can use it wirelessly. To do it, you just need that both iMacs are connected to the same network and the app ScreenRecycler

  • Can you Run Lion server on iMac and use monitor for another computer

    With lion server you don't need a monitor and I figure why buy a mac mini when i could by a 27" imac and use it as a display and a mac mini running lion server.
    I have been going over the scenarios and am trying to decide if I should buy the TB display or a second 27" imac.  Eventually I will have 3 27" displays... but I want to run Lion Server off of one of the imacs... and use the display with the other imac.
    do you know if it is possible to use the display of the imac for a mbp or another imac while running an operating system (lion Server) on the computer at the same time.
    not sure if I made my self clear there or not.

    Ryan as long as both the Mac Mini and iMac have Thunderbolt you could use the iMac as an external monitor for the Mac Mini. The current machines with Thunderbolt connections are 2011 iMacs, MacMini's, MacBook Air's & all MacBook Pros.

  • HT1758 Can i connect my non apple laptop to my iMac and use the iMac as an extra/dual screen while using my laptop?

    Got a new laptop from work, no choice on the type, but want to plug it's docking station into my iMac so I can use dual screens while using the laptop. Can I use the Ethernet port for this?

    Welcome to Apple Support Communities
    Target Display mode only supports Late 2009 and Mid 2010 27-inch iMacs, and Mid 2011 and newer iMacs to use them as external displays, but it only works over Mini DisplayPort or Thunderbolt, not Ethernet.
    Your PC needs Mini DisplayPort or Thunderbolt (depending on your iMac) to be able to use your iMac as an external display, so it is probably that you cannot use the iMac as an external display. Instead, look for information in the Internet about VNC viewers that allow you to do that

  • How do I connect an older imac to my new imac to use as a second monitor?

    Hi !
    I was wondering if it were possible to  connect an older imac to my new imac to use as a second monitor?
    My older imac is from 2006. The new one is a 2012 imac.
    Any advice would be appreciated.
    Thanks,

    Look this article over, the key is to connect either mini display port or thunderbolt and using CMD+F2, let me know if this helps or if it doesn't work out. I'll find another solution if this doesn't work Joel ^_^

  • Got an iMac and used migration tool (PC to Mac). When I try iTunes i get The file "iTunes Library.itl" cannot be read because it was created by a newer version.... download iTunes now? but i have it already???

    I just got an iMac and used migration tool (PC to Mac). When I try to then open iTunes i get the message
    <The file "iTunes Library.itl" cannot be read because it was created by a newer version.... download iTunes now?>
    ...but i have it already downloaded, when I press download now, it tells me I already have it, but it still won't let me open iTunes???

    Unless you've tried to install an older version of iTunes that message likely indicates a corrupt library file. See Empty/corrupt library after upgrade/crash...
