Using a 24" LED Cinema Display without a Mac

I've never owned a Mac, and don't really plan on ever doing so. However, I do like some of the hardware. The Apple Cinema Display series is an impressive line, and I love the way they look.

I decided to use one with my PC (Windows Vista), and it took a bit of tweaking. However, now that everything is working properly, it makes all of my other displays look severely outdated.

How did I get things working?

First of all, you'll need some sort of Mini Displayport to DVI converter. I happened to use one made by Atlona. It works like a charm.

Secondly, you will want a way to control the brightness. There are some 3rd party programs out there that will do this for older Cinema Displays, but not for the newer models such as the 24" LED ACD.

I happen to have found a workaround for controlling the LED backlighting directly. You need to install the Apple Boot Camp drivers found on a Jaguar version of the Mac OS (or a later version, I suspect).

Once you do that, you can use the Boot Camp Control Panel to control the monitor brightness.

However, you can't do this if you have admin rights (strange, I know). It will give you an error saying it can't find the startup disk (presumably some sort of partition that is created if you are actually running a Mac). To get around this, you need to run the apple control panel without admin privileges. So, create a non-admin account on your computer, and then use the 'runas.exe' file to run the Apple Boot Camp control panel executable.

Here is an example of the shortcut I created, using a non-admin account named 'Test' on the computer 'NOVASTAR':

C:\Windows\System32\runas.exe /user:NOVASTAR\Test "AppleControlPanel.exe"

When you can control the LED backlighting brighness directly, you will see what a difference it makes in the quality of the display. Video card controls alone do not do the LED 24" ACD justice.

I suspect the above will work with Windows XP as well. I don't know about Windows 7.

+You dont have any problem with The full boot camp drivers?+


Well, not yet.
Works normally.

+I ask because of the GPU drivers, since boot camp will instal GPU drivers too.+


I have been installed ATI Catalist Drivers, and don't have observed Boot Camp has installed something over it.

+I bought one hd5970 with minidisplay port, I hope dont have any problem to acess the bios.+
+You can access your bios setup?+


Sure, that not problem.

Thanks for the post, I've been trying to do the same. I have a few questions for you:

1. The drivers for the control panel (brightness), which ones did you install? I have the bootcamp drivers, but am not sure which .exe to run. Can you post more details about this process?

2. Are you able to get the monitor to work during post? When I turn my computer on, the monitor doesn't show anything until windows has finished loading. My guess is that this is because the LED Cinema Display doesn't support 640x480. Do you have this working, if so then my theory is wrong. Like you, I'm also using an Atlona adaptor, I'm using the one with the USB power, I guess this is their 2nd generation.

3. In device manager, I've noticed that Display iSight appears twice. The first one looks good, but the 2nd one has a "no driver" warning. I can't figure out which driver it wants. It shows up under "Other Devices". I've been ignoring it as the camera seems to work fine with Skype anyways. Do you see the same? In my case, I'm running Win7, so things may be a little different here.

Thanks in advance for your time and help!

Hello, mantispid.

Please, tell what driver you had used, from what Bootcamp version?
I have tried install 'AppleDisplay' from Bootcamp 3.0 driver package, and full Bootcamp 3.0 driver package, but after installation in Device Manager still 'Plug&Play Monitor'.

And where can find the 'Boot Camp Control Panel', AppleControlPanel.exe from Bootcamp is not working alone.
