Is it possible to use the iMac display as en external monitor?

I want to connect my powerbook up to an iMac using the display as an external monitor for the laptop. Is this even possible? Any feedback would be appreciated.

Hello,
I've seen this post at least a hundred times. Has
anyone actually had the gusto to try this idea?
I don't remember where the page was. But, I posted it's link several months ago in the forums during another discussion.
But, the guy who had done it to his iMac G3 had very poorly documented his conversion.
Basically, he took and wired signal to same signal on the monitor, and adapted his power supply and other items to work properly in the modified setup.
So, it is possible. You just need to sit down with the schematics and wire signal to same signal, and make sure you account for all the variables. It may take some resistors, etc. to get the adaptation just right.
I don't have any reason to do it myself, so I'm not going to tinker with it.
If I remembered the link, I'd post it. But, it wouldn't do much good anyway since his HTML formatting was severely messed-up. The end-result was accurate information that was scrambled around on the screen in such a way that you couldn't decipher it anyway. If he had done the HTML work properly, it would be in a formatted table. But, instead the information was scattered all over the screen in an illogical format. So, it wasn't of much real use.

    is it possible to use an i mac as an external monitor connected to a pc?

    No unless we are talkign about a late 2009 or 2010 27" iMac. Otherwise PC's don't have the correct outputs. Please look over Apple's FAQ on that subject (Target Display Mode) and you will see what I mean:

  • Possible to use the MBP display for use with XBOX 360 through DVI port?

    Hi everyone, I know that the topic sounds ludicrous to probably a lot of you. After all, how dare a Mac user use a Microsoft machine right ;)? Well, truth be told, I like the 360 and that's the only MS product I prefer to use.
    Anyway, I'm going to be picking up my own 360 within the next few days and am currently deciding whether to also buy a new HDTV with the purchase or if I can wait. I'm going to be buying a new TV eventually but I was hoping to put off the purchase for a while since I remembered that the 360 can hook up to monitors through VGA. So what I want to know is whether the DVI port on my MBP is output only or will it accept input signals? Also, if it is possible to hook up my 360 through the DVI port, is there an easy way to attach the DVI-VGA adapter to the 360 seeing? By this I mean, the adapter is only about three inches or so and it would be pretty difficult to attach both machines to each other, so I was wondering if there might be a female-female VGA adapter bridge or some easy method of doing this.
    Thank you all for your help in advance.

    Outsider,
    Check out this link and enjoy the 360 on your MBP!

  • Is is possible to use the iMac g3 without a mouse

    Have a iMac g3 and wanted to know if I can access anything without a mouse, until I can find an original one.
    Thank you

    Or you can use the up and down and sideways arrows to navigate through windows.  If you go to System Preferences>Keyboard>keyboard shortcuts, you'll find a long list of actions you can perform without a mouse.

  • Can I use the Retina Display as an external display?

    Hi. I know it's not a huge issue- the graphics are amazing on the retina macbook pro.
    But I was wondering if I could use the screen on the laptop as an external display, say, for a desktop computer that would have a huge, power thirsty, heat sink, graphics exploading graphics card?
    Would this be possible through thunderbolt at all?
    Thanks!

    Well, I don't know if this could provide input at the full native resolution of the macbook pro- but it does seem like it might do the trick. It's the "eye tv" that allows you to input a video stream into your mac.

  • Can I use iMac display as an external monitor with a pc?

    I have a Windows laptop with VGA output. Can I connect this laptop's VGA output to mini display port of my 27" iMac?

    This can't be done. VGA is an audio signal and there are no converters to turn it into a digital Display Port (DP) or Mini Display Port (MDP) signal. DVI and HDMI are digital signals (with HDMI having audio and a different physical connector) that can be converted into an MDP signal, but doing so requires an expensive converter or an even more expensive converter and scaler if you want to get full resolution on the target display. The cheaper but perhaps more complicated alternative is to replace your PC video card with a DP/MDP card after which you should be able to drive the 27" iMac display without any converter. Apple didn't include DVI/HDMI input capability in the 27" iMac because that would have required additional circuitry that would have raised the price substantially.

  • Can I use my iMac 2009 as an external monitor for a MacBook Pro

    I will soon be getting a new MacBook Pro with Retina display. It has an HDMI port.
    My current iMac 21.5" late 2009 model seems to have a port with what looks like a little monitor symbol, next to the firewire port. And the specs say:
    Graphics and video support
    NVIDIA GeForce 9400M graphics processor with 256MB of DDR3 SDRAM shared with main memory3
    ATI Radeon HD 4670 graphics processor with 256MB of GDDR3 memory
    Built-in iSight camera
    Mini DisplayPort output port with support for DVI, VGA, and dual-link DVI (adapters sold separately).
    Support for extended desktop and video mirroring modes
    Simultaneously supports full native resolution on the built-in display and up to a 30-inch display (2560 by 1600 pixels) on an external display
    Does this mean that port is just for video output to an external monitor? Or is is possible to also do video in?
    On the one hand it feels like a waste to use a perfectly good iMac as a monitor. But the MacBook Pro actually has better specs, and so I was wondering if it is possible anyway.
    Thanks,

    Thanks for your reply. After reading the article though, I'm still not really sure what the answer is. For example, you mention something that can be done, with some hurdles to go through, for 27" iMacs. Mine is a 21.5" iMac, but seems to have the same port you mentioned in the article. Or maybe it isn't. Anyway, I'm still not sure if it is possible after reading that. Interesting information though.

  • Can you use your iMac 27" as an external Monitor for a PC?

    After doing a bunch of research I figured it's not possible to do on models later then 2010, BUT I came across a few motherboards (Asus Z87-DELUXE)
    that have thunderbolt capability and obviously before I go out and spend $400 I'd like to know if it's 100% possible.
    So, would it be possible to run a thunderbolt cable from a PC to an iMac to use it as a standalone monitor or would the iMac completely reject it purely based on the fact it's not a apple product?
    Or could you just use the "Mini DisplayPort to DVI Adapter" to get it to work?

    Even though the PC motherboard might have Thunderbolt capability you need to research further to see if the Thunderbolt port on the board supports video out and is certified to work in Target Display Mode. To date I have not seen any that meet this criteria, another PC shortcoming. Also you may benefit by reading Apple's FAQ on Target Display Mode, at least book mark it.

  • IMAC 27 inch as external monitor for PC issue

    I'm not able to use the iMAC 27 inch as external monitor with my PC which has ATI 5870 graphic card. I use DP (displayport)-> miniDP cable. Any help?
    Thank you.
    M

    It appears that none of the ATI HD 5XXX series cards are compatible with the iMac unless they have a mini displayport connector (ie eyefinity models and the $700 HD 5970). The ATI HD 4xxx models with the full size display port do seem to work also. I am curious as to whether this incompatibility carried over into the new iMac models....

  • T61 and the Intel Graphics Card error - external monitor not detected

    T61 with Vista 32 bit, Mobile Intel® GM965 Express Chipset and an Advanced Mini Dock.
    I am trying to use the DVI port and an external monitor. The driver does not detect the external monitor.
    Uninstalling the Intel driver the Generic profile will work on the external monitor, but is overly fuzzy, how do I get the T61 to recognize my external monitor with the right drivers?
    I am currently running the Intel Driver Ver. - 7.14.10.1329, which provides the message under Multiple Display:
    Two displays must be connected to the computer before you can use this feature. Please connect another display.
    Of course my 22" monitor is connected.  That is the frustrating part.  I have also uninstalled Presentation Director, just in case, but then re-installed after it seemed that wasn't the problem.
    There is a newer driver from Intel but it is not Lenovo approved yet I guess. Though I highly doubt this is the problem. What can I do?
    ~~
    I did post a thread on the thinkpads.com too, but so far haven't had any luck.

    Well the new dock came but didn't fix the problem.  Now my nice new T61 is packed up in a depot box, waiting for DHL to come pick it up.
    dkaufman1 -- I guess we do have different problems.  If I set my T61 to display to the DVI port in the bios I get a blank screens on both the DVI connectd monitor and the laptop screen until the OS boots when I have the laptop in the dock.  The only way I can see the bios screen to set it back to the ThinkPad LCD setting is to boot it disconnected from the dock.
    I really hope that this problem is resolved, as I really like the T61 otherwise.  I was even using it with the VGA cable connected to my 22" monitor, but it was pretty hard to take.   I'm now back to my old desktop hooked up to the same monitor via DVI and it is quite the relief, even if it isn't as zippy as the T61.

    Is it possible to use an iMac as the display for a Mac mini?

    iMacs late 2009 or newer can be used in Target display
    mode.  Any older, no can do.
    The only other way is via network Screen Sharing or
    some otherVPN network like solution.  The issue here
    though is that video performance will be pretty severely
    hampered.

  • How to use the iMac last generation as a display for a PC

    Hello,
    Can someone confirm if it's possible to use an iMac last generation as a display for a PC (Windows)  and if, yes, which type of cable or accessory is required?
    Thanks
    Stephanie

    Sorry, but you probably can't. The current and previous generation of iMac can only be used as displays with other Thunderbolt-equipped systems.
    http://support.apple.com/kb/HT3924
    Only if your PC has a Thunderbolt port that supports video out would this be possible, and such systems are currently rather rare.
    Regards.
