Broken Graphics card Target Display mode

I have a 2009 iMac that now has a faulty graphics card, the computer crashes once photoshop runs.
I don't have the mac at the moment to test, but could I still get target display mode to work?
How well does the mac need to run before TDM can work?. If I power it up, sometimes it won't get any further than the apple logo, can it work then?
Thanks
Matt

I purchased a Belkin AV360 and it did not work with Target Display Mode on my new mid 2011 iMac.
After a bit of searching on why it didn't work I've found all sorts of articles on this issue with older display port devices not working with target display mode on the new Thunderbolt macs. I sure hope this can be resolved with a firmware update, or by someone (Belkin/Kanex) making a new Thunderbolt compatible adapter.
And I don't know if anyone has confirmed it yet since the feature is so hard to take advantage of now, but I'm hoping this years iMac at least accepts 1080P signals in addition to 720P and the native panel resolution. It would be worth the wait for an adapter if it accepts 1080P as well, which would make it at least more future proof since everything has gone to 1080P so rapidly.
I was really counting on my new iMac doubling as a TV/Console display in my room - it was part of what justified the high price of the investment and the convenience of the all-in-one design. I would be very pleased if Apple can help resolve this.

HT3924 any HDMI converters available for iMac target display mode yet?

Just got this bed with a pop-out TV, and I'm thinking about getting an iMac 27" to use instead of a TV. Problem is, I'll also want to attach an Apple TV or Freeview box to my iMac - so I can play content from my iPad / watch live TV from the freeview box. This would be technically possible with target display mode, except the Apple TV / Freeview box don't have mini display port output.
Anyone know if there are HDMI to mini display port adapters available yet to facilitate this? From what I've read most of them only output from mini display port to hdmi, not the other way round.

I have a Asus HD6570 2GB Graphics Card in that computer with HDMI out, DVI out, and VGA out. I have a Asus HD6570 2GB Graphics Card in that computer with HDMI out, DVI out, and VGA out.
None of those will work.
It has to have a Mini DisplayPort, not evn a Display port will work.

How can I recover files from an iMac 2009 with a broken graphic card.

My old iMac has a broken graphics card. Instead of getting it replaced or fixed I needed a computer quickly. I decided to get a MacPro. I'm able to boot up the old iMac and my MacPro can now read the files in the iMac. I have been transferring files from the old iMac to the MacPro via ethernet connection as the USB to USB was running slow. Is there a faster way to transfer the files between the two?
Is there a way I can delete the files on the iMac when I'm done transferring the files I wanna keep? Right now it won't let me delete anything from the iMac hard drive especially the locked Files.
Is there a way I can connect another monitor to the iMac if it has a broken graphics card? I'm assuming it's the graphics card cause I researched it on youtube and my iMac has the same screen they're describing when you have a graphics card issue.
Thanks.

What is the iMac model? Does it have Thunderbolt? Do you have Firewire? Can you connect them via any combination of Firewire & Thunderbolt?
Thunderbolt & Firewire support something called 'target disk mode'
How to use and troubleshoot FireWire target disk mode
OS X Mountain Lion: Transfer files between two computers using target disk mode
That will allow you to see the iMac as an 'external hard disk'. They are the fastest way to access the full disk.
At the moment it sounds like you are using file sharing over ethernet - this is not the way to access everything on the iMac's disk & will result in you failing to copy data that you don't have read permission.
You can also erase the iMacs HD over target disk mode if you really want to remove the OS & data.
I don't believe it is possible to connect up two Macs via USB to USB so please clarify what you used. You may have been doing the right thing before you switched to ethernet.
EDIT:
Nevermind about the model, 2009 iMacs didn't have Thunderbolt so you will need to use Firewire 800 to Thunderbolt.

How to activate Target Display Mode on iMac 27", Late 2009?

Hi all,
I'm trying to use my iMac as a display for my PC. Unfortunately I can't activate the iMac's Target Display Mode (TDM) through a DVI-to-miniDisplayPort cable.
As far as I know, the TDM exists on my iMac (27 inch, Late 2009).
I am following these steps:
(1) start the iMac,
(2) start the PC,
(3) press Cmd+F2,
but nothing happens on the iMac (as if I didn't press anything).
The PC's DVI output works on another screen, though.
Here are my settings:
- iMac: 27 inch, Late 2009, 2.8 GHz Intel Core i7 with miniDisplayPort, OS X 10.8.4 (12E55)
- PC: Gigabyte's GTX 770 graphic card with DVI-I output, Windows 8 fully updated
- between the two: DVI-D cable plugged into Apple's DVI-to-miniDiplayPort adapter
Any advice?
Thanks a lot :-)

Please very carefully read:
support.apple.com/kb/ht3924
In it you will see that TDM only works on a late 2009 iMac in Mini Display Port to Mini Display Port, no other configurations will work. If your iMac is an early 2009 iMac (please check the Tech Specs for each on Apple's website) TDM is not supported on that model.

Play sound in Target Display Mode

I would like to play sound from my custom PC to my mid 2010 iMac 27", I have display through a mini display port cable, connected to my graphics card. (XFX Radeon 6870)
I have installed AMD Catalyst, which is giving me the option to select sound output through my graphics card, and therefore 'should' work, it obviously does not, does anyone know how to do this?

I think you have a mis understanding of what TDM is, please carefully read Target Display Mode: Frequently Asked Questions (FAQ) - Apple Support

Apple Mini DVI to DVI Adapter to connect Win7 tower to iMac / Target Display Mode

I currently run Windows on bootcamp on the iMac (Mid-2011), although the tasks I perform (3D modelling, rendering and such) cause the Mac to get very hot, and as a result hae a slight burn mark on the LED LCD screen.
I am buying a Windows machine, and am to uninstall bootcamp and use the Mac purely for OSX, but use the iMac screen as a monitor for the tower using Target Display Mode. My issue is - the Windows 7 tower only has DVI output. And as I understand, the Mid-2011 iMac only supports Target Display Mode via a thunderbolt cable.
My question is - Will the Apple Mini DVI to DVI adapter allow me to connect the DVI-only tower to the iMac? Thanks in advance x

Oh, I should mention also that the iMac is the 27" model. Mid-2011 3.4Ghz Intel Core i7 with 4GB RAM and 1TB Harddrive. And ATI HD5450 1GB Graphics.

How can I use my 27" iMac (2010) as an additional display to my Windows 7 PC (target display mode)?

So I have purchased a windows machines so that I can play all my favourite games on, and it's not so much a problem rather I have a 27" iMac that I would like to use as an additional monitor for said games.
I have had a look at this article on using the iMac as a display for another computer and things looked promising. I think I need a bit of help getting there though as I can't find definitively anything online to tell me exactly what I need. Most stuff talks about connecting other Apple computers that have mini display ports.
My PC's video card is an nVidia Geforce GTX 650 Ti that sports 2 DVI ports and a mini HDMI port (adaptor to full HDMI was included). The iMac has a mini display port. I went out and got a HDMI cable and Moshi Mini DisplayPort to HDMI Adapter (with audio) to try to use the iMac as the additional display. I connected the PC with [a generic] HDMI cable to the adaptor which ran to the iMac and went through the appropriate steps (ie. pressing CMD + F2) to initiate target display mode. Nothing happened.
I have read that other people with different situations tried an SMC reset, but this didn't work for me either.
At this stage I wanted to see if the DVI port would do anything, or perhaps looking at a particular kind of HDMI cable, but wanted to see what the community can offer up as advice.
Any assistance would be greatly appreciated.
Thank you.

10.7.2 breaks Target Display Mode

You might find that Target Display Mode stops working after you update to 10.7.2 The solution, discovered by JohnAtBurn in https://discussions.apple.com/thread/3363289, is to use Disk Utility to repair permissions. (This may be the first time repairing permissions has actually fixed anything.)

Tight VNC Viewer runs on Windows 7 and is used to connect to PCs running VNC such as Mac OS X with Screen Sharing enabled. Tight VNC has never been installed on the Mac OS X box.
The only difference between when this worked and when it stopped working is the 10.7.2 update which seems to have broken VNC.

Qosmio G30-177 broken graphic card

Hi,
it looks like i have a broken graphic card in my G300.
The boot screen (selection of boot media) looks like the matrix ;-(
While windows is booting it looks like vertical stripes. The boot process crashes with a blue screen.
This is both in the internal display and an external monitor.
Is my idea of the broken graphic card right?
Can the graphic card be replaced?
Yours Rdiger

Hi Rdiger
I have the same problem and effect like you with my G30-155 since today afternoon.
I am really asking me now what big chance it can be that we both have the same problem at the same time.
Can it not be that we both got a virus that effected the grafic card ?
Any help and tips are very welcome.
Regards Charly

Can windows 8.1 in boot Camp display in target display mode on an IMac?

I have given up on Windows 7 running in Boot Camp on my 15" MacBook Pro and displaying it on my 27" IMac via thunderbolt and Target Display Mode.
The FAQ concerning Target Dsiplay Mode farily clearly says Windows 7 won't work.
But it does not say Windows 8.1 will or will not drive Target Display Mode via thunderbolt.
see: http://support.apple.com/kb/HT5219, question 29
Has anyone found that running Windows 8.1 in BootCamp on a MacBook Pro Retina mid 2012 will display via a thunderbolt cable in to Target Display Mode on a late 2013 IMac 27"?
I don't want to go to the trouble of installing Windows 8.1 and trashing my otherwise functional Windows 7 Boot Camp installation unless it is going to display properly on my late 2013 27" IMac running OSX 10.9.3 via thunderbolt.
Thanks in advance!

no, tdm doesn't work under bootcamp regardless of which windows is being used, imho i don't think it will ever work under bootcamp

Your answer is likely in Target Display Mode: Frequently Asked Questions (FAQ) - Apple Support If you are familiar with this document, please re-read it and I suspect you may find something you either missed or are doing incorrectly.

IMac 27" Target DIsplay Mode + Answer to Windows 7 Boot Camp Install

First, I'd like to address the handful of complaints I've come across about installing Windows 7 via Boot Camp on the new 27"iMac.
The issue of the screen going blank when almost done has an easy albeit annoying answer. Simply connect the iMac to an external display, I used a small vga lcd with the Mini DisplayPort to VGA adapter. When the iMac's screen goes black the external lcd will continue, and when Windows 7 starts up it will download the updated ATI drivers. From there alls well.
Second, my problem.
Target Display Mode is a great feature. It worked great when I first used it, and it works great now except for the fact that the Command+F2 button combination stopped working. I have to manually unplug my MacBook Pro in order to get my iMac's original screen up. At first Command+F2 would allow me to switch back and forth, and now it does nothing.
Any suggestions?

Well, the usual first things to try for a display-related issue are
Reset PRAM
http://support.apple.com/kb/HT1379
and of that does not help, reset SMC
http://support.apple.com/kb/HT1543
which is basically unplugging the iMac from power and reconnecting it following the precise procedure.
Note: After resetting PRAM, you should go to System Preferences +Startup Disk+ pane to make sure your internal drive is selected (highlighted) as the startup disk.

Target Display Mode - Connecting pre-Thunderbolt Macbook Air to Thunderbolt iMac.

I want to use Target Display Mode in order to display my late-2010 Macbook Air (pre-Thunderbolt) to a Thunderbolt-based iMac. Is there an adapter solution to connect, say, a mini display port + USB port on the MB Air to the iMac Thunderbolt port, such that TDM would work?

Depends upon the situation. Take a look at this blog:

Target Display Mode not working iMac 27(2012) Bootcamp to iMac 27(2013)

Hi All,
I recently purchased an iMac 27" 2013 which replaced my iMac 27" 2010.
===============
PREVIOUS SETUP
===============
(1) iMac 27" 2012 - Running Windows 8.1
(2) iMac 27" 2010 - Running OS X Mavericks
(1)+(2) were connected with a Mini-Display-Port cable.
(1) was using (2) as external display while (2) was set to Target Display Mode using CMD+F2
==============
CURRENT SETUP
==============
(1) iMac 27" 2013 - Running Windows 8.1
(2) iMac 27" 2012 - Running OS X Mavericks
(1)+(2) are connected with Thunderbolt cable.
(1) can't use (2) as external display anymore becuase CMD+F2 has no effect anymore on (2) in this scenario.
If (1) and (2) are both running OS X all works as expected.
I am aware about the support hint from Apple where they state TDM is not working under Bootcamp.
And I agree, while booted into Windows Bootcamp this machine can't serve as external display. Makes sense because TDM is baked into OS X display drivers.
Anyone had the same experience and came to a soltuion?
Thanks,
Martin

"Apple has no plans to implement a client driver for Windows since there is no Thunderbolt SW stack available for Windows like there is for Display Port."
That is a little bit funny since Gigabyte and other big companies have said that 2014 is the year that they are going to implement Thunderbolt in many motherboards.
"GIGABYTE 7 series motherboards are the very first to offer fully certified dual onboard Thunderbolt™ ports. Capable of connecting up to 12 devices plus 3 digital displays simultaneously with breathtaking data transfer speeds that can transfer 1TB of data in only five minutes, GIGABYTE Thunderbolt™ motherboards offer the fastest connection interface on the desktop PC."
Have you asked Apple about that? I dont understand why Apple is crippling Thunderbolt on their devices...

Target Display Mode iMac 27 mid 2011 with Mac Mini 2011 bootcamp

Hello,
I can't seem to use Target Display Mode with Bootcamp.
My configuration:
Imac 27" mid 2011 with osx 10.8.4
Mac Mini Server 2011 with osx 10.8.4, bootcamp 5 and Windows7
Both are connected via Apple genuine Thunderbolt cable (2m).
When I boot the Mac Mini into OSX then Target Display Mode works perfectly and I can see the osx installed on the Mac Mini on the iMac display.
However, when I reboot the Mac Mini into Bootcamp (windows7 x64) I can't put the iMac in Targt Display Mode and get to see Windows 7 on my iMac screen.
http://support.apple.com/kb/ht3924#8
The following article says that this should work, however once I reboot osx on the Mac Mini the iMac leaves Target Display Mode immediatly and will not return to Target Display Mode.
Any advice? I contacted Apple Support and a Sr. Enginner said it should be supported and he's checking with a higher tier.
Thanks

Yes, it does.
