Problems when cinema display attached to PowerBook

I have a new PowerBook G4 (15" stretch) with OS 10.4.5. I also have a new 20" Apple cinema display. When the display is attached to the PowerBook, I've noticed a host of problems, including: HP LaserJet 1022 (new) prints only about 50% of the time--requires restart to get it working; USB mouse and keyboard attached to the display freeze (although I can still move the pointer with the trackpad on the PowerBook)--requires restart to get them working.
The printer is plugged directly into the PowerBook's USB port. Nothing else besides the keyboard/mouse are plugged into the display's USB ports.
I've reset the power manager several times; I don't let the computer go to sleep, although I do let the screens go dark after 15 minutes. I've tried all the usual printer fixes short of resetting the print system.
The PowerBook and printer seem to work fine w/out the display; the printer works fine on another PowerBook.
PowerBook G4 Mac OS X (10.4.4) RAM = 1.5 GB

I am experiencing the same problem with a Samsung Aquos 52" connected thorough a Onkyo receiver/amplifier. The connection is DVI to HDMI to Onkyo amplifier and HDMI-HDMI to the TV. The main 23" Cinema Display flashes during turning on an off of both of TV and the amplifier and even when the TV is off and the amplifier is on, unless you restart the computer, it would keep detecting a second display, the only solution so far was to unattach the second display DVI to HDMI cable from the computer. Otherwise, several freezes occur after several flashes of the cinema display and eventually either the dock o the whole screen would freeze...Anyone knows how to avoid this issue? Btw, my id card is NVIDIA GeForce 6600.

PowerMacG4 won't start without old Cinema Display attached

PowerMacG4 867dp (Mirror Door)
NVidia GeForce4mx w/ADC+DVI
20" Cinema Display w/ power switch, on ADC port
Acer 23" G23HL, on DVI port
I replaced my failing ADC with a new display (with much-appreciated help from this board!) Works fine as dominant display (currently not mirrored) but I need Cinema Display attached and powered up to run system. The Power Switch on tower lights, but won't shut down system, or start it without ADC attached. (It won't control system at all, only Power Switch on ADC works) Nothing in Preferences seems to apply. Should I just duct-tape new Display over old ADC and move on??? THANKS!

Thanks for your response BD Aqua. I don't have those diagnostics and frankly still wouldn't have a clue if I did. I was hoping I had overlooked some simple Preferance-type step in the change-over, but beyond maybe changing the old battery next, I'll just put one screen in front of the other- fortunately I've got room. Thanks again for your reply!

Turning off MBP Display when Cinema Display connected

Hello,
Sorry if this is a stupid question but I have a 23" Cinema Display attached to my MBP via DVI and although it's great to watch DVDs on, I would like to turn off my MBP display whilst doing this to save energy, reduce the distraction etc - is there a way of doing this?
Help appreciated.

You'd need an external keyboard and mouse as well. Follow these steps:

Alternatively, there are haxies that disable lid-closed sleep:

Online conference participants hear echo when cinema display is connected via mini-displayport, even though I am using headphones with mic.

When I use Google Hangout or GoToMeeting, other participants in the meeting hear an echo of their sound -- loud and obtrusive. When I mute, it goes away.
This only happens when I am using my Apple Cinema Display 27" (recent vintage) connected via the mini-displayport (natively, not an adapter).
On my end, i don't hear their echo, but I do hear waves of squelching -- basically it sounds like their end is trying to adjust their input down to account for what it thinks I saying, even though I'm not talking, it's just the echo making that happen.
Sometimes this doesn't occur -- it seems to crop up intermittently, but happens around 75% of the time at some point in a conversation.
I am using iPhone-compatible in-ear earphones with built-in mic; the earphones are the rubber seal type, so there's no sound escaping them that the system should even be able to hear.
I have my audio set up for "Headphones" as output device.
Input device is set up as "External Microphone" -- this part confuses me because even though I know my Cinema Display has a microphone, the OS seems not to list it as a separate input device. So I wonder if it's getting confused trying to use both the cinema display's mic *and* the earphone mic? (see dropdown image)
OS version 10.20.2; Macbook Air 13 inch, "early 2014" and Apple LED Cinema Display 27inch
Earphones are skull-candy brand iPhone compatible (with built-in mic), plugged into the macbook air's earphone jack. (without the display connected, this has always worked fine -- and with a prior non-apple display that had no mic/camera this was not a problem)
This is an ongoing issue in our office, in fact ... especially troublesome in client meetings.
I haven't tried other configurations, other than when using the Cinema Display's USB connector, the same thing happens.
It also happens even when I'm not using the "USB PnP Sound Device" you see listed in the dropdown here -- that's something I use for controlling music output to my desk speakers.
A general question: is there no way to control the cinema display's mic and/or camera more directly?
(EDITED TO ADD: Ok I see in the Cinema Display manual, there should be a listing for "Display Audio" in the input list, but my SysPref panel has none listed. See other screenshot. I wonder if this is the problem??)

Curious, is the 30-inch Cinema Display you have, one listed in this Support Article:
•Apple Cinema Display (20-, 23-, and 30-inch DVI) - Technical Specifications
or is yours a later build series; which one do you have...? This says Mini unsupported.
The specifications vary across the line of Displays, as do the graphic support in Macs.
I'd suspect your version is a later 30-inch display, but it may be one of these. And a
newer 27-inch Display has the Thunderbolt cable.
In any event...
Good luck & happy computing!

Why can't I shut macbook air when cinema display is connected?

I just upgraded from an older MacBook Pro to a new MacBook Air. I have an older Cinema Display that I want to use with the new MacBook Air. I can get the Cinema Display to mirror what's on the macbook air screen, but I would like to be able to shut the MacBook Air and just use it like a desktop computer when its connected to the display (I have an apple bluetooth wireless keyboard and mouse). Every time I shut the MacBook Air it shuts down and the Cinema Display goes black. I had no problem getting it to work the way I wanted with my old MacBook Pro. Any wisdom on this? Thanks!

Is the computer connected to AC power?

As far as I can recall, there is no way to stop the POST sequence from searching for either IGD or PEG graphics and still proceed to boot an OS. Graphics will be required to set up the UEFI/BIOS settings, boot device, and other housekeeping chores anyway. How are you going to load the chipset and other drivers? Once in the UEFI/BIOS and the graphics settings are disabled, it 'might' work as you want. Only way to tell if it is in the OS then would be the HDD LED or the mainboard DeBug LED showing AA, A0, or the CPU temperature depending on the UEFI/BIOS version.

Mouse cursor problem when external display connected

When my external Apple display is connected to my MacBook Pro (Retina, Mid 2012, 10.10.2) the cursor jumps to a spot on the external display and will not release from it. I move the cursor anywhere and it jumps back to that original spot. Cursor operates normally when the external monitor is not attached. I've used the monitor for a few years with no problem, but this started just recently. I do not use the external monitor daily and I cannot recall doing anything that might have triggered this problem. Any ideas on a fix? Thanks.
Bill

Just an update to close this. Call Apple Support. An advanced support tech walked me through several procedures. Eventually, the problem disappeared after deleting a bunch of plist files and startup items. Which particular file caused the problem we don't know. But problem gone and I will monitor going forward. Hopefully it was a one-time corruption of one of the preference files.

Mouse skipping problem when external display connnected

I recently purchased a Macbook, and I connect it to a Dell 3008 display using the mini DisplayPort to dual-link DVI adaptor. My issue is that when the Dell is connected and in use, the mouse pointer skips across the screen when I move it, like something is interrupting the input for a very brief period, and it's being interpolated wrongly when the input comes back.
The problem doesn't occur when the external display is disconnected, and it happens with wired USB, wireless USB and wireless Bluetooth mice.
No adjustment of mouse sensitivity options seems to fix it, and the interruption in the pointer movement seems to happen at semi regular intervals of between 5 and 10 seconds apart, although I can't be 100% sure.
Interestingly, it doesn't happen when I connect a lower resolution external display using the same adaptor. So it only happens at 2560x1600. I'm wondering if it's a problem with a hardware accelerated mouse cursor and the NVIDIA graphics driver.
Anyway, it's a real barrier to me using the Macbook, so hopefully someone has a solution.
Thanks!

Same problem here: wireless MS Laser Mouse 6000, either a samsung or LG external display connected via mini adaptor. Have the MS intellipoint drivers installed. It began to happen about a fortnight ago, and seemed to coincide with the Java update 4/Bluetooth Firmware/ Safari update applied on 24/6. This may have been around the time I changed display preference to 'best performance', so could well be a graphics driver issue?
In my case, it tends to happen in certain spots on the screen, and the likelihood of a skip seems to depends on the speed I'm moving the pointer. Faster = more likely.
It's messing up my tanking in warcraft something terrible.

MBP changing color when thunderbolt display attached

So I have the last gen 17" mbp running 10.8.2. the color on the display looks great except when I attach my new thudnerbolt dislpay. The color temp of the MBP display goes really cool (blue) when the thunderbolt display is attached. Whenever I unplug the display, it goes back to normal. Anyone else seen this or have any idea what is going on?
Thanks,
Scott

Bought a TB display to use with my 2011 mbp last night. Hate that it doesn't have a power button.
Really hate that the usb implementation seems quite broken. I spend 95% of my time in Windows, and while the display functions, usb doesn't really. The apple usb keyboard i bought sticks, and my dell mouse hangs frequently. both are plugged into the display, but they work fine when plugged into the laptop directly. I also have a jabra usb headset plugged into the display.
I have noticed I can worsen the situation by actually using the display hardware. If I start a call using the headset, the keyboard and mouse become even worse. If I start using the facetime hd camera on the display, they become horribly erratic.
Apple definitely has some work to do. They are billing this is a docking solution and it is completely unusable as such right now.

Crash when second display attached

I'm using Aperture in this configuration:
Aperture 1.1.2
MacBook Pro 15" (with external monitor)
OS X 10.4.7
Aperture is randomly crashing when the second external display is enabled and Aperture is configured to use it. I can crash Aperture fairly easily, although the crashes are random. If the second display is enabled but not being used by Aperture, I do not have crashes.
Questions:
- Has anyone else seen this issue?
- How do I fix it?
Thanks
MacBook Pro Mac OS X (10.4.7)

I am not experiencing crashes, but I am noticing interference on the monitors when Aperture is running using 2 monitor mode. As I move from picture to picture, or zoom in or out of pictures, I see small blue and red squares all over the screen ... as if something was writing to the video buffer. The problem does not manifest itself at any time when Aperture is not running.

Color problems with duo monitor (MPB and 24' Cinema Display)

I have a new 24' Cinema Display attached to my 15' macBook pro 2.66 (not the new one with the SD slot) and I keep getting weird colors on the MBP display.
Here is a screengrab from the MBP. The main display is fine. What is my MBP screen experiencing?!
http://www.madreview.com/images/screengrab.jpg
You can ell the colors are off on Tiger Woods on the bottom and on the background. Please help.

If I may jump in, I have almost the same question and would like to clarify the Cmd-F1 suggestion. (I'm looking at buying the 24" LED for my slightly older MBP with max resolution 1440x900.) If one runs this monitor in extended desktop mode, you can reach the max resolution for the monitor, if I understand correctly, but is some of your "desktop" then spread across your built-in MBP LCD? That's less useful than having the entire 24" available for keeping multiple windows open.
Just want to understand whether this is really worth it! Thanks, and PMFJI.

Brightness Control and 2 x 24" LED Cinema Display

I think I've discovered a bug with the Display System Preferences panel.
I have a new 2009 Mac Pro with one ATI 4870 and one Nvidia GT120, each having a 24" LED Cinema Display attached. When I keyboard brightness buttons (F1,F2), only the one display changes brightness. When I use the sliders on the Display System Preferences panel, both sliders control the one display. So I can change the brightness of one display 3 different ways, but no way to control the other (or both at the same time, which is most desirable).
What is even more interesting, is that the controllable panel changes depending on which monitor's USB connector is connected into which USB port and in what order they are connected. After trying different USB combinations, I once got the slider on the left screen to control the brightness of the right screen, and vice versa, but the controls are seemingly randomly reassigned on system sleep, and I havent been able to duplicate that behavior since.
What is the best way to report this? It appears to be a bug in the USB code associated with the brightness sliders and the Display Preferences panel. My desired behavior would to have the keyboard buttons control the brightness of both displays at the same time.
Thank You

No problem with my 24" and a 2008 Mac Pro with an nVidia GE120. I'm betting that the problem isn't with the monitor but with the video card. I also have a unibody Mac Book Pro and discovered the color shifting problem without any monitor attached. It started occurring when I used my Huey Pro Pantone monitor calibrator on the LED display of the MBP. Recalibrating the display exposes the color shift. Putting the monitor back to the shipping calibration makes the display problem go away completely.
At the same time, I never noticed any problem on the 24" cinema display before calibrating it, and exposing it to the hardware monitor calibrator exposed a way out of gamma color. After recalibrating the monitor in hardware, the picture is utterly flawless - best I've ever seen on a display of this size. I think the Apple software calibrator is a piece of junk and I suspect that it messes with the monitor in unhelpful ways. I'd suggest having the monitor professionally calibrated and see if that cures the problem.
Also, it will be interesting to see whether anything in the 10.5.7 update fixes any display issues being reported prior to the release yesterday.

Using Cinema Display with mid-2010 MBP, post-Yosemite: corrupted MBP screen

For a couple years I've been using a 27" Cinema Display attached to my mid-2010 MacBook Pro 15". The dual-display setup works great for my home setup.
However, since upgrading to Yosemite, the MBP display often completely corrupts and reverts to complete gibberish, with fragments of the UI and desktop littered all about the screen. Dragging a window over to that screen usually "redraws" it sufficiently enough to keep working, but soon the problem re-appears. The screen of the CInema Display (my main working area) never corrupts, only the MBP screen.
My setup worked great in Mavericks, but something in Yosemite isn't driving both displays properly. Can anything be done, aside from downgrading to Mavericks?
Andy

I am having this exact same problem. 2010 iMac with NVIDIA GeForce 9400 256MB. I have it hooked to a 30" display through a DisplayPort to DVI-D adapter. The 30" is fine, but I have graphical corruption constantly on the main iMac screen.
This all started as soon as I updated to Yosemite a couple days ago.

Can't control volume on LED Cinema Display from keyboard

I have a LED Cinema Display attached to my Mac Mini. The volume control buttons on the keyboard don't work anymore. The only way I can change the volume is to use the volume control on the video I am watching. I tried the headset trick on the output port on the Mini, and now that works with the volume keys. But, the display volume is still not working. Any hints?

The reason why that has happened in the first place is because MAC OS, is programed to not adjust the volume through an HDMI interface. If you have the volume control shown on the upper bar like i do, it appears light grey.When you click on it you cannot move it up or down. This is of course what the keyboard controles for volume. It does not control the program.
