It's way simpler than that guys. The brightness on the display is controlled by simply pressing:
Control+F1 OR Control+F2 to adjust brightness on your secondary screen (the one without the menubar).
F1 and F2 to adjust brighness on your main screen (the one on which the menubar is located).
If you have adjusted settings in System Preferences for the ...
There IS a solution to this problem, I searched and purchased quite a few adapters but finally I got it to work:
1) Purchase this USB-C to Display Port adapter:
2) Purchase this Display Port to "Active Dual Link DVI". It is important that it is an active converter ...
I search and search, finally find this article https://discussions.apple.com/thread/2649213?start=0&tstart=0 .

I was having the same issue on my MacBook Pro. Here is what I did to resolve it:
Ensure lid of laptop is open
Plug in power, mini-display, AND USB from the Cinema Display into MBP
Restart computer (*this was ...
After weeks of trial and error, I have finally achieved 2560x1600 resolution on my Apple 30-inch Cinema Display connected to my MacBook Pro,15-inch, 2016 laptop.
The trick is to go from USB-C to Mini Display Port (MDP), then to dual-link DVI. Unfortunately, this does take two adapters, but at least the full monitor's resolution is supported.
I used the ...
I may have an answer for you.
The AirPort card in this model is located at about where the play/pause and volume buttons are and the antennas are built into the display. When you close the lid, the antennas are being pointed sideways instead of up.
Not only that, but now you've added an extra layer of glass and aluminum to block the radio waves being ...
Your calculation is solid. Everywhere I've seen it 109 PPI (which is probably what you intend with DPI) is what people report for the Thunderbolt Cinema Display:

The short answer is no. Apple's Thunderbolt Display requires a thunderbolt signal (and only that) to operate.
The spec page for the display implies very strongly that Thunderbolt displays will only work with Thunderbolt Macs.
This happens to concern me since I own a previous-generation iMac (pre-Thunderbolt) and really wanted to have the option to use it ...
Plugs are the same, cables are not. The thunderbolt cables contain chips and firmware.
I haven't used the new Thunderbolt display, however I am aware of the following:
MiniDP Macbook -> MiniDP iMac 27: works fine.
Thunderbolt Macbook -> MiniDP iMac 27: works fine.
MiniDP Macbook -> Thunderbolt iMac 27: does not work
Thunberbolt Macbook -> Thunderbolt iMac ...
(I solved my own problem right as I was about to post here.)
The Mini DisplayPort must be plugged in before the USB cable. Unplug both, plug them in in the correct order, and it should recognize the sound.
Unplugging only the USB cable will not work.
This question is old, but in case anyone is still looking, a driver that works is here:
Look for the link to Beta Versions and Old Releases for the latest.
The beta version works with Windows 10 Creators update as of 12/25/2017.
Ok, I've found the answer and it is confirmed at 109 PPI.
The panel in use in the display is an LG made panel with a part number of LM270WQ1 and the full tech specs of the panel (from 2009) are here.
The spec sheet denotes the pixel pitch at 0.2331mm (or 0.009177") which works out at 108.968 PPI

Yes, you can add another monitor if you use a USB video adaptor. No, there are no USB video adaptors that support dual link DVI monitors such as the 30" Cinema Display.
Many USB video adaptors will support 1920x1200, some a little bit higher.
However, you will find the USB video to be slow and annoying if you are used to high performance video.
I suggest ...
Are they logging in as the same user as the currently logged in user? Post-10.7, Mac OS X VNC supports logging in and either sharing the current desktop, or generating a new virtual desktop.
HOWEVER, I believe if you're logging in as the same user that's currently logged in, it will take over the computer as though you were accessing it directly. The ...
Personally, I'd go with the expensive option - you have a grand's-worth of screens there; why not have them both accurately profiled?
The first downside of manual calibration is not knowing which of the two is 'more correct' in the first place - the second is actually getting them both to look the same...

Thunderbolt is a multiplexing of several signals - PCIe bus, USB 3.1, power and DisplayPort. On the 2017 MBP you have at least 2 Thunderbolt 3 ports. This means you don't need to convert from TB to DP/mDP as the signal is already there.
The LED Cinema display uses an mDP interface and the Thunderbolt display requires a Thunderbolt connection.
So, all you ...
The Apple Cinema Display uses a DVI-Dual Link interface which is becoming very long in the tooth so adapters are going to be few and far between. It wasn't a widely accepted standard so even when it was current, adapters were already difficult and expensive to source.
What you need to get connected is to go from USB-C DisplayPort to Dual Link DVI. This ...
I never used stay but I am using Moom (Apple store) and pretty happy with it. It stores windows positions and has configurable hotkeys. There is no automatic settings for different displays but since you can assign hotkeys to configuration is not a big issue.
It is very stable.
If your computer is running or is capable of running OS X Lion, or OS X Mountain Lion Screen Sharing is able to use a feature called Virtual Display to allow remote user a view that does not mirror the actual screen on the Mac, not sure if energy saver is able to know about the Virtual Display and not keep the Physical display active, but it is worth a try.
From what I've read, the inability to connect a mini DisplayPort device to an Apple Thunderbolt Display is because of a bug in the Apple Thunderbolt Display. If you connect another device in between the Thunderbolt Display and the Cinema Display, they both should work along with your MacBook Pro's internal screen.
You'll need a graphics card that can output Thunderbolt (if such things exist, I have not checked). The Apple Thunderbolt Display can only accept input in the form of a Thunderbolt signal, Mini DisplayPort will not work.
Apple does sell a Mini DisplayPort variant of their 27" display, so if you don't yet have the display you should get that instead
If you are talking about a Thunderbolt equipped 15-inch MacBook Pro then yes according to this:
Apple Thunderbolt Display (27-inch): Connection options for Thunderbolt Macs
Interestingly you can also drive two from a 13-inch MacBook Pro, it will disable the built in display.
VGA is an analog signal and your Cinema requires digital so you need more than a simple cable. You need an appropriate interface box, called a VGA to DVI Scaler, such as the Gefen VGA to DVI Scaler Plus. (Shown for reference only—this is not a recommendation.)
You will also need the appropriate adaptor to use the DVI signal with your monitor.

You can do a couple resets to the computer to see if it resolves the issue.
Disk utility (application) > select 'Macintosh HD' on the left-hand column > and click VERIFY disk under FIRST AID.
This takes about 2 - 3 minutes and will let you know if you have a corrupt hard drive which might be causing that issue
