Imac to tv monitor back to projector.

can this be done? in what way I think I need some help. or could i do
this with a portable DVD player? HELLP! ASAP! Thank you!

Hello,
What video adapter cable do you have for the iMac? If memory serves this particular iMac model had a Mini VGA connector. If that is the case then you'll need a VGA to VGA cable and must use the PC input on your TV.
To force the iMac to the same resolution as the TV connect everything up and reboot your Mac. If you still get the error open System Preferences and select the Displays control panel. Click on Detect Displays. The correct resolution should be chosen automatically. If it isn't let me know what options are displayed in the list for both displays. You'll have to choose Mirror Displays to see the same display on both.
Alastair.

    You're right - that link goes to a dead-end (sorry OP ).
    Looks like it's all down to the paid for one now, although you can use it in demo mode for 14 days:

  • Trouble arranging monitor display with 2 monitors and a projector

    I just installed Yosemite (it's pretty awesome) and I am having a little trouble with screen arrangement. I think it has something to do with each display now having it's own menu bar. But what do I know?
    I have an iMac, a second monitor and a LCD projector. I was sort of navigating out the top of second monitor to get to projection screen. And the way back to screen one was tricky. I was running the dvd player and it lost picture and I had to get to my iMac and fiddle around and then move dvd app back to projection window again. I'm sure there is a better way to handle this.
    My lcd projector looks way better now. Very happy about that.

  • IMac as a monitor for iPad photographs.

    Is it possible to use my iMac as a monitor to share my iPad screen when scrolling through photographs? This is my plan for classroom use.

    This is from the iPad User Manual.  So I think if you purchase an Apple Digital AV adapter cable, you'll be in business.
    When you connect iPad to a TV or projector using a USB cable, the attached display automatically mirrors the iPad screen. Some apps may support using the attached display as a second monitor. Check the app’s settings and documentation.
    To view HD videos in high resolution, use the Apple Digital AV Adapter or a component video cable.
    Make sure the video cable is firmly connected at both ends, and that it’s a supported cable. If iPad is connected to an A/V switchbox or receiver, try connecting it directly to the TV or projector instead.
    Make sure that your TV has the proper video input selected, such as HDMI or component video.
    If no video appears, press the Home button, disconnect and reconnect the cable, and try again.

  • G5 iMac as a monitor?

    My non-Intel iMac G5 is showing its age. Though fully functional, I find a need for an Intel based system to take advantage of newer software and Snow Leopard. Is there a way to use the iMac as a monitor for use with a Mac mini?

    For all intents and purposes, no. In theory, it could be done, but the effort and expense would be greater than just getting a new monitor.
    Personally, if you have an G5 that's still actually working, I'd keep it as a disaster recovery system. If your Mini ever needs to go in for repairs, you have at least something you can limp along with until it comes back. Maybe you'll find one of those rare programs that doesn't work with Rosetta, or maybe some program that you really like but is no longer being updated and won't work on anything higher than 10.5. There are still a few good reasons to keep the old G5 around.

  • Old Aquablue G3 iMac as a monitor?

    Folks, I'm as dumb as a box of rocks, never more so than when it comes to computers. That established, I recently bought a Mac mini and hoped to use my old G3 iMac as a monitor. The 'poser' at Compuserve sent me home with all manner of expensive cables and adapters and thought, "in theory", that it could be done. Can it? If so, what do I need?
    Thanks in advance,
    Rick

    Well theoretically this would be possible and it really depends on which iMac we're talking about.
    On the iMac tray loader CPU speeds 233-333 the video comes out of the back of the mass store/logic sled. It's the old Mac standard connector and to make this work you'd need to feed the male plug that plugs into that sled. So you'd need a VGA to Mac female adapter. I actually think I have one of those. That would be easy to make work.
    Now for the iMac Slot loaders CPU 350 - 700 that would be a much bigger problem. You could probably make it work but it would require extensive disassembly of the iMac. The feed to the video section of the iMac comes off the back of the logic board from underneath and feeds RGB Cable 992-4034 which is normally screwed to the divider panel. So to make that work a special cable would have to be made up. So probably not worth the trouble.
    I'd just look for a regular VGA monitor. Around here Apple Studio monitors and the old large CRTs are going for nothing and even first generation LCD monitors are going for very cheap. That would be a great way to go. Otherwise go out and buy a Apple Cinema monitor like the 20" and really go in style.

  • New iMac loses 2nd monitor

    My new Imac 21 - i7 - Lion - dual monitor (connected with thund-hdmi adaptor) has a strange behavior.
    Everything works fine, but when the system goes in power saving mode, on coming back sometimes the second monitor becomes gray (working but no wallpaper), sometimes comes back normally, but ALWAYS all applications windows goes back to the main imac monitor.
    I've tried to switch of the 2nd monitor and the behavior is the same. So is not a power saving problem.
    It seems that the imac always autodetect monitor situation on the fly and moves windows back to the main monitor.
    The problem is that the "moving windows back function" seem to be faster than monitor detection.
    Is there a way to say to lion: "I always have two monitor, please don't change"?!?
    thank you for help.

    I suspect it may be the adapter.  I would recommend trying the one Apple recommends here or trying another connections such as a VGA or DVI assuming the monitor has that type of connection.

  • Can i use my imac as second monitor for my  pc / notebook

    Can i use my imac as second monitor for my  pc / notebook

    Without any knowledge of the year machines you have it's impossible to answer that question. iMacs adn MBA's have been around for many years now so we have no idea of the exact specs your machine have. Remember when posting you need to be complete and paint a picture for us as we aren't there to look for ourselves. Your question should be  posted something like:
    " I have a 2011 27" iMac and a 2009 MacBook Air, can I use the iMac as an external display for my MacBook Air?"
    BTW what you are referring to is called Target Display Mode. Apple does support that on some 2009-2011 iMacs. You can find additional information at:

  • IMac Display as Monitor for PC

    I have an iMac 2.66 GHz Intel Core 2 Duo, 2 GB RAM, OS X 10.6.2 and an old Dell Pentium III 933 MHz which I would love to somehow connect together. I am considering to install Linux on my Dell and use both computers for different reasons. I wonder if I would be able to use my iMac like a monitor for the old PC.
    I have come across the following discussions but it seems that they don't cover my case, i.e., an old Dell that does not have a port for a display port.

    --but the basic problem is that you need a DisplayPort signal to drive the iMac monitor. You can convert a digital DVI output (or HDMI which is the same thing with audio and a different physical connector) to DP format with an expensive converter, but there is no way to convert an analog VGA signal to DP format. The cheaper but more complicated solution for a PC with DVI output, and the only solution for one with VGA output, is to replace your video card with a DisplayPort or Mini-DisplayPort card. Mini-DisplayPort has the same signal but a smaller physical connector.
    This was not actually Apple being arbitrary: DisplayPort is more efficient and less expensive than DVI/HDMI because it dispenses with a lot of the conversion hardware needed for that format. Therefore Apple couldn't provide DVI/HDMI compatibility without increasing the iMac cost substantially.

  • Use older 2008 iMac as second monitor for new iMac

    Hi all,
    I have one of these older machines that has no real purpose
      http://support.apple.com/kb/sp485
    but would serve me very well as a second monitor for my brand spanking new iMac.
    The specs seem to note that there is a video output - but I'm not seeing anything about video IN.
    Is it possible to use this older iMac as a monitor?

    that looks cool, and there is a free trial.
    I am not keen on using the WiFi to do this - my old iMac has firewire but the new one doesn't.
    Besides using the ludicrously expensive Thunderbolt <-> Firewire 800 convertor
    http://store.apple.com/uk/product/MD464ZM/A/thunderbolt-to-firewire-adapter
    is there any other way to create a wired connection between these devices? I'm not sure if there is such a thing as a USB <-> USB network connection.
