Thunderbolt display flickers but only in Windows 7

My Early 2011 MBP in Bootcamp to Windows 7 will flicker, blank out then come back maybe once every 5-10 minutes. It only happens in Windows 7 and not in OSX. Anyone else see this issue?

Stick with DVI.
Too many have reported issues with Windows 7 and VGA through Thunderbolt. Seems the Windows 7 driver only does digital, not analog.
If you must use VGA with Windows 7 on a Mac, the suggested paths are:
USB-VGA adapter, bypassing Thunderbolt
Run Windows in VM and let Mac OSX run it all since it can make analog (VGA) signals.

Macbook air charges fine with the Thunderbolt screen connection but only sometimes with the 45 W chargers.

My Macbook air charges fine with the Thunderbolt screen connection but only sometimes with the 45 W chargers. It seems to be the combination of the chargers and the computer. I was thinking whether the Thunderbolt screen has a larger power supply which easier activates the computer to actually receive the charge. It reminds me a bit of the Nokia Lumia 800 telephone, which when totally exhausted needs a strong charger to be activated again. I am as frustrated as most others. I have got two chargers, and both of them sometimes work, other times not. Sometimes, they start working after a while. Is Apple meanwhile coming up with a solution or advice how to handle such situation?

I just got my ATD and late 2011 MBP up and running. I've not tried running without the power adapter from the ATD plugged in, but I just tried and didn't have any problems with the display not waking. You may want to take your query to the ATD forum - https://discussions.apple.com/community/peripherals/thunderbolt_display - perhaps someone there has experienced a similar issue.
Good luck,
Clinton

In Mac OS X v10.7, the $HOME/Library folder is a hidden folder.
Open Finder and use one of these:
* Go > Go To Folder (Shift-Command-G) and in the dialog type: ~/Library
* Open the "Go" menu and hold down the Option key to make the Library appear
You can also use this command in a Terminal window to remove the hidden flag.

How to get screen content onto external VGA screen? Do have thunderbolt-VGA adapter but only get screensaver across

how to get screen content onto external VGA screen? Do have thunderbolt-VGA adapter but only get screensaver across

VGA and DVI do not carry sound. Only HDMI.
Use a minidisplay-to-HDMI adapter. Then when the TV is connected to the system use "System Prefences > Sound > Output" to select the TV for sound.
Or connect speakers to the output port of the MBP.

2nd apple thunderbolt display in not detected by Windows 8.1

Installed Windows 8.1 on a late 2013 Mac Pro. Have two thunderbolt displays. The 2nd display is not being detected by Windows. There is only one display listed in device manager. One display works fine, the river listed for it is Generic PNP display.
Any ideas on getting 2nd display to work in Windows 8.1?
Thanks

OMG, I was just about to buy a new wireless card because I have the same problem.
Some weeks ago my wireless adapter disappeared, the card disappeared altogether even from Device manager, after I installed a new bluetooth driver and after I was connecting to my phone 3G via USB cable.
But then it came back after I left the laptop shut down and unplugged for a whole night. It worked for a few hours and after closing the lid and opening it again wireless adapter was gone again, never to come back.
I tried changing drivers, holding the power button for 20 sec to hard reset the laptop, fresh install of Windows, load BIOS defaults, and even installing Windows 10 in VHD (dual boot) and see if it will reappear there.
Always the same - the wireless adapter doesn't exist any more.
However, buetooth has been working without problems, which I find strange.
I read online about similar situations, and all answers point that the wireless card stopped working and needs to be replaced.
But @Papelinas - you say you even bought and installed a new wireless card and STILL have the same problem???
I can't believe that something in motherboard got damaged and that only wifi doesn't work...
I've had my Y2P for 6 months, and I don't really have time to send the laptop for repair for some time, I'm using it...
I guess I'll still try to buy a new card, and just hope the wireless adapter will reappear...

New 27" Thunderbolt Display Flickers when attached to new 27" iMac

I'm using a new 27" iMac. I require a dual-monitor configuration so yesterday I purchased a new 27" Thunderbolt display and plugged its built-in Thunderbolt cable into the Thunderbolt port of the iMac. I now have a huge desktop space that spans two monitors. With that in mind…
At least once every few minutes the new Thunderbolt display blacks out (i.e. flickers) for approximately one second. The symptom is very similar to what a Windows-attached display does when the screen resolution is changed. A quick Google search indicates others are experiencing the same problem although most complainants are using a MacBook or Mini, not an iMac.
Apple posted a firmware update for the Thunderbolt display a few days ago. I installed it successfully but the problem remains. Any advice?

UPDATE:
I received a call back from a senior tech at Apple. The salient points are as follows:
(1) Apple engineers are well aware of the problem.
(2) They plan to release a firmware update for the display at some indeterminate time.
(3) The fix for this problem will not be bundled into the forthcoming 10.7.2 Lion update.
Given that the flickering problem renders the Thunderbolt monitor virtually unusable as a desktop extension for a 27" iMac, combined with the fact that Apple has no idea when a fix for the problem will be available, my decision to return the monitor for a full refund is a virtual certainty.
AppleCare objected to my conclusion that the Thunderbolt monitor is "incompatible" with the iMac. Perhaps they're right. I'm not super technical so it's possible that I used the wrong term. It's a semantic distinction though. The bottom line is that Thunderbolt displays flicker when attached to a brand new 27" iMac and my personal opinion is that one is better off not purchasing this device until Apple fixes this major flaw.
Apple asked me to make a video of the Thunderbolt display manifesting the problem. Here it is.

Is there a way to connect a Thunderbolt Display to a PC running Windows 7?

I am thinking about purchasing a 27 in. display for my home office. Can I connect a Thunderbolt Display to my work computer ( HP notebook running Windows 7)?
Thanks,

Not unless the notebook has a Thunderbolt port (unlikely).

External Display Flickering/Blanking out on Windows 8.1 Boot Camp

OK, so I have a MBP 15" Mid-2012 model running the latest versions of Mavericks and all software and drivers on Windows are up-to-date. I am using my external display through an Active HDMI adapter for Mini DisplayPort/Thunderbolt (one that broadcasts audio as well as video).
So, this adapter and image seems to work perfectly fine on the Mac side, however, when I flip the switch to Windows 8.1, the external display goes haywire and goes blank and flickers with occasional lines and static across the screen. Image comes back every few seconds and then will suddenly lose signal.
I've been reading around the internet and I've seen that this could be a hardware issue in that Intel never put support for Thunderbolt/Mini DisplayPort on their chipsets for Windows, not a driver issue.
How screwed am I? If not so screwed, what steps do I need to take to attain functionality of the external display while running Windows 8.1 through Boot Camp?
Note: my Mac does not come with an HDMI port already installed like current Macs. This was the last high-end Macbook Pro to have an optical drive installed on it.

On a later rMBP, I can connect three displays via TB at full resolution.
One suggestion is to try a Display-miniDP cable, instead of a converted HDMI signal, if the monitor will accept a DP connection.
If it works correctly on the Mac side, it would be a driver issue, since the hardware supports it with one OS, but not the other. The effects you describe indicates that some pins on the HDMI are not getting correct signals to maintain image refresh rates or pixel sync. When you use the current connection, does the Control Panel -> Displays detect the model and name correctly? If not, the EDID detection is failing.

PB display flickers, but external monitor still OK

Hi all,
I've just bought a faulty powerbook to see if i can fix it. It's a G4 15" 1Ghz Titanium DVI. The fault is that the powerbook display frequently becomes corrupted. it's actually a beautiful effect, but not very practical! Every few moments, minutes sometimes, the display looks as if deep colours are gradualy bleeding accross it, until it becomes unreadable. the effect is sometimes psycedelic and sometimes textured like oil on canvas!
Anyway, simply moving the angle of the display a little clears the screen and everything's visible again. At no time does the system crash or anything; if there's an external monitor conected in Display Mirroring or Extended Desktop mode it doesn't show any artifacts and continues to work perfectly. It's only the powerbook's own display that exhibits the fault.
i'm presuming therefore that the logic board is OK but that there is a loose connection somewhere (where I don't know!). Could it be the invertor board however?
does this all sound familiar to anyone?
thanks!
TiBook 1Ghz (DVI) Mac OS X (10.3.9) 9600/350

Hi, efunc. If your situation is such that you could happily use the Powerbook as a very compact desktop computer with its built-in display closed and an external monitor, keyboard and mouse connected, you might be able to do so for a long time without fixing anything at all.
If you really want to use the Powerbook as a portable, you'll have to crawl inside and look around for the trouble. The fact that changing the built-in display's angle clears the problem suggests strongly that the cause is in one of the very thin, fragile cables that pass through the display hinges. These can become pinched or abraded in the very narrow passageway there (especially if the hinges are fatigued and begining to break), leading to faulty insulation and short circuits or even severed cables. There is very little room there to make any repairs, if that's the case, and cable damage is not always easy to see. Replacing the cables, one end of which is sealed inside the display bezel, is essentially impossible. A professional technician, when faced with bad display cables, replaces the entire display instead of trying to pry the bezel apart.
Because the cables are so thin, flexible and delicate, the motion of the display being opened, closed and adjusted is, in itself, very unlikely to loosen (or tighten) any of the cables' connections inside the body of the Powerbook. But a loose connection there is possible, and it wouldn't hurt to check. Complete disassembly instructions are here, and will show you where the display cable connections are located.
If you don't find a bad connection, the inverter board is the least expensive part you could replace in the hope of solving the problem. But I doubt that adjusting the screen angle would "fix" (even temporarily) a problem caused by a bad inverter, so I suspect that isn't where the fault lies.
Good luck.
EDIT: Oh, dear — I just realized that you're the very same efunc who reports a whole different set of problems with his used 1GHz Tibook in a different thread. If all those problems are occurring in the same Tibook as the display problems discussed in this thread, most of what I've said above is out the window, and the source of all the problems could be anywhere, including the logic board, or even multiple sources.
My comments above were based on the assumption that the problem you reported in this thread was the only one you were having with the affected machine. If that assumption is wrong, disregard them.

MBP13, Intel HD3000 graphics, Thunderbolt Display flickering

I have a early 2012 (late 2011?) MBP13 with a 2.8Ghz i7, 8GB of RAM, and the Intel HD3000 graphics. For awhile I was running it with a Samsung 24" monitor, and it was perfectly fine. However last fall I upgraded to the 27" Thunderbolt, and it now flickers to black, sometimes for a couple seconds. It will do this during normal operation (browsing, Office docs, etc.) but where it really shows up is when I play video streams, be it Netflix, Amazon, or Youtube. In other words, not narrowed down to a particular codec.
Additionally, if I have a firewire drive connected to the display, and I'm doing heavy work off of it, i.e. iMovie editing of HD video content, the display will go black indefinitely.
I have verified this behavior with two other HD3000 equipped laptops (both core i5 2.3Ghz models), so it's not just my laptop.
So it's the monitor, right?
Not exactly. I got a new base model MBP13 in today with the 2.5Ghz i5 and the Intel HD4000 graphics.
The result? No problems, even full screen Netflix. Not a flicker.
I'm wondering if this is a limitation of the HD3000 chipset, and I'm just out of luck, or if there's a fix available. I've also tried it under both 10.7.5 and 10.8 (all iterations).
What's odd is that the variable is graphics chipset, however it's not just video; it occurs during anything that would be bandwidth intensive over the Thunderbolt bus.
Thoughts?

No one? I guess I'll give Apple a call.

Text aligns centre instead of left, but only on Windows 7 PCs.

I have designed a website on a Mac in CS5. It works fine on all Macs and PCs running XP/Vista but there are problems on Windows 7.
For some reason text boxes that I have aligned left work fine as mentioned above, but every text box aligns centre on Windows 7 PCs.
Can anyone offer any advice please? I'm pretty new to this by the way!
Many thanks!

This is how it looks on my Mac and how it should be.
This is on the PC with blue boxes (thanks for link will check that out) and all text centered.
Like I say, text displays fine on windows XP in explorer and firefox, just not on Windows 7 PCs.
Any ideas?

PB display works, but only sometimes. Any thoughts?

The computer is an older PB G4 Titanium 500Mhz. Currently running OS X 10.4, though I am in the process of a second erase and installing 9.1 that came with it.
Out of nowhere last week the screen just froze, on restart it was completely black. But after turning it on and off a few times the screen will appear, but it will freeze within a half hour or so of use. I have erased the drive and reinstalled a new system, ran the Hardware Test, replaced the battery(as it wasn't holding a charge), and the power cord which was showing signs of wear.
I don't believe it is the inverter as the screen is not even faint, it's completely "off", no sleep light etc. The only thing that I am able to do on a consistent basis is start up from the installer CD. This is what leads me to believe it's not the display itself. But at this point I am beyond baffled.
Anyone encounter a similar issue or have any idea what could be going on?

Apologies, wrong board.

Odd HD noise but only in Windows

I wasn't sure where to post this, but since it pertains to my Boot Camp Windows partition, I thought I'd start here.
I've noticed for some time, now with Windows 7 and previously with Vista, when I'm in Windows, that there is a fairly loud, dull "clunk" when I open any Windows folder, or open any attached external hard drive. The sound is metallic, though not pingy, and appears to be hardware related. However, there's no such sound when I'm in Snow Leopard, which, of course, shares the same hard drive. In my experience, physical hard-drive issues are not specific to partitions. Fortunately, the noise does not occur when using applications, only when opening folders.
Anyone have a similar experience or have an idea what this might be about?
Thanks,
Nick

Not a dumb question at all, as you are entirely correct. I've used Windows for years, but never heard that sound and don't recall ever changing from the default "click." Thanks!!!!

Z87-G43 latest BIOS (180) now no USB, but only in Windows?!

I performed the bios update today with the assistance of MSI support.
No problems with their USB stick method, that part went fine.
However, now, I lose all USB once the motherboard boots.
I Have USB in the BIOS setup screens, etc. Once the OS boots, I lose the USB stack.
Whats happening here?

Good grief...
It turns out that the USB 3.0 and other USB stack drivers become MEANINGLESS after the BIOS update.
Re-installing these brought the things back online.
Be sure to also install all the latest chipset and USB drivers as well.
sigh. Documentation and testing seem to be weak with this organization.

MBPr Windows and Thunderbolt Display

Hi there,
I am trying to have my MBPr and Thunderbolt Display working under bootcamp with Windows 8. All the peripherals attached to the TBD are working fine but the display remains black/off. I am pretty sure that a solution exists but can't find the right. I've tried and under Windows 7 behavior still the same, whereas under MacOSx TBD display works fine.
Thanks for you support !

I made the usb stick back when I installed windows 7 that made my imacs amd gpu see the monitor connected as it did in osx and in the same was as any other windows computer with a connected extra screen
(so I turn it on in windows display settings and maybe the amd catalyst software i forget)
when I upgraded to win8 it just used the win7 driver and it still worked fine
same when I later got te official win8 drivers from apple
