Can the LED Cinema 27" brightness be adjusted on a PC?

[Newapplefan72]

Hi Zuffy!

I also have a XPS 15. I went to an apple store earlier today, hooked the cinema display to it, and everything worked perfectly.

The problem with the applecontrolpanel is that it won't work if you launch it from within an administrator account. Yeah I know...pretty weird!!

You just need to create a standard user account, and launch the application from there. Worked perfectly for me.

Best regards

thanks for the tip, however the proper format is:

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

I wrestled with this for a day!
I have a new (Lenovo Thinkcentre) PC that I bought only beacuse I wanted the LED Apple Cinema Display (27"), and my Dell didn't have room for the graphics adapter with midiDisplay port.
After trollling around this and other forums and trying some different suggestions, I found this one posted by "cide" on the "hardforum.com":

It works great! I have win 7 32bit professional, and a XFX Radeon 6870 card.

Brightness Control

--------------------------------------------------------------------------------

I actually found a better way to get the AppleControlPanel for Brightness to work in Windows 7.
#1) Right Click on "Computer" -> Select "Manage" and in the users area create a user account called: Test (with password: Test) -> Not an admin account!

#2) You have to create a shortcut to the EXE itself, and in the shortcut box change the part that points to the EXE itself (Not the 'Start In" area) Change to: "C:\Windows\System32\runas.exe /user:test C:\AppleControlPanel.exe" (Or whatever/whereever your ControlPanel filename is...If shortcut is in the same folder as Exe you do not need to enter a harddisk or filepath before AppleControlPanel.exe)

Before creating shortcut like this I was getting the Startup Error every time I tried to control brightness, And there was no way I was going to depreciate my Win7 install with unneeded bootcamp pollution. BTW: My disk drives run in AHCI mode and theres no chance I'll be changing that to IDE to make something run right

Let's Try Thinking A Wee Bit Harder, Eh?

I have one hooked to my PC and have been working on this issue. The short answer is mostly no. I have tried old acd brightness modifier programs and even found a way to get boot camp installed on my pc. The closest I was able to control brightness was the hack with boot camp, however I could only control brightness less than 50%. For some reason, I could not obtain the brighter settings even on the max setting. Eventually, I did find one interesting thing that solved the problem. I have an old macbook pro (dvi only). While I cannot hook the actual monitor to it, I can hook the USB monitor cable to it. The brightness controls on the ACD monitors occur through the USB cable. On my macbook after hooking the USB up, I simply went into the brightness setting and turned it up. Once it is set, the display remembers the setting and stays bright when hooked up just to the pc. This completely solved the issue. So if you own a old macbook, you might be able to fix your brightness issue through this manner. I must say Apple is really being cruel to customers to not offer them some way to control brightness on non-mac boot camp pc's as many people share monitors with multiple machines.

Hope this helps you!

How about using a little bit of the Scientific Method.... keep things simple...

If you have an AMD or nVIDIA GPU, there are native maintenance and tweaking utilities which will handle a monitor just fine. AMD Vision Engine Control Center will detect and modify all settings for even monitors as far back as the 20" Cinema Display from April of 2005.

Well, the AppleControlPanel isn't a simple color adjustment tool. It actually adjusts the brightness of the LED in the display. I know with my nVidia card, there is no way to do that from the Catalyst Control Panel.

The bootcamp driver has gigantic issues with most modern PC's (AHCI) and AMD Vision Engine Control Center or nvidia equivalents will just **** up the display signal and not affect the actual backlight brightness at all.

So i wrote a stand alone brightness controller tool for apple displays.

Not working at all...

I'm using my ACD27" with my PC running PNY Quadro2000, and I'm not getting anything on screen at all. I am using a Display port to Mini Diaply port cable connected to a female mini DP to mini DP coupler to connect to the display.

Win7 x64 won't let me install Boot Camp from Snow Leopard DVD neither...

So I grab the AppleDisplayInstaller.exe from Boot Camp 4.0, the installation went through, but that didn't do anything, screen still off.

Any idea?

This old post saved me a headache... worked a treat !

Wow, thank you mate, you made a really great app! Works like a charm with my Windows 7 64 bits and GTX 670
