Thunderbolt monitor problems

I have a 2013 Macbook Pro HD and use the Thunderbolt monitor. It's a great combo save for only one issue. The monitor starts to flash (black to standard screen). It gets so bad I have to unplug the Thunderbolt connector and replug it in. The only fix to stop it is to restart my Macbook pro. Even that doesn't always to the trick.
I have looked at blogs/Google searches for fixes and havent seen any.
Help!

Try 'resetting' the Display instead of your MacBook Pro. Unplug it from mains and leave it unplugged for about 15 minutes and then plug back into mains.
If this doesn't fix the problem, then you need to take your entire kit into your local Apple Store/AASP.

Thunderbolt monitor problem

I am not able to get a 21" thunderbolt monitor to work with the Mac using an adapter w/ system 10.6.8. The monitor does not respond at all.

What resolution and refresh rate for the VGA connected monitor?
18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

Did you try to hook up both monitors to the Belkin adaptor? Trying will determine if your monitor has a bad input port. See if the Belkin adaptor is the problem. I have never used that specific adaptor, but I have always had luck with the Dr. Bott's DVI for ADC adaptor. Best of luck.

MacBook Pro/Thunderbolt Monitor blanking out

I have a MacBook Pro with 2 Thunderbolt monitors. My system is connected up like this:
MacBook Pro (running in clamshell mode) -------> Thunderbolt Port on MBP -------> Thunderbolt Display ------> Built in Display Thunderbolt Cable ------>Thunderbolt Display 2.
I also have a Thunderbolt disk drive attached to a thunderbolt port on the back of display 2.
I have a couple of problems every now and then. At times that second display blanks out for a second. I have noticed, it is most likely to happen when I put some IO on that thunderbolt disk drive. It just seems to me like the bandwidth of thunderbolt should be able to handle this.
Secondly. Sometimes when I boot up, the system considers that second display as the first which screws up my screens. I usually have to reboot to get it to work right. I notice that if I boot up with my MBP open, the system always considers the 2nd monitor in the chain the first display. Seems like it would always default to the first monitor.
Any help you could provide would be appreciated,
Rob

The Thunderbolt drive should be the first device on the chain, with the Displays being the last devices on the chain.
That should solve both of the problems.
If not, call back or post in the Apple Thunderbolt Display forum.
Good luck,
Clinton

Dual Thunderbolt Monitors both Cooked?

I pruchased a Thunderbolt Monitor back in 2011, ordered a 2nd last week one so I could use it with my new Mac Pro Retina. When side by side they are both crooked, the left side is lower than the right side which makes a small step inbetween the monitors when placed together. I assume this is a design flaw since they both have the issue, but would anyone measure their monitors to see?
Additionally the monitors are slightly different; the backlight looks different which affects the colors on the monitor and the bezel width appers to be slightly different. I called apple support and had a pretty horrible experience, i'm not sure the person on the other end could effectively communicate how to sharpen a pencil. Needless to say they were no help. I have to say this is the first time I have been dissapointed in the product and support of Apple. Does anyone else have the same problems with dual monitors?

Please see Mac Pro (Late 2013): Using multiple displays - Apple Support for an explanation.

Thunderbolt monitor stopped working

Hi All -
I have a new retina MacBook Pro 13-inch and Thunderbolt monitor. The monitor worked fine for a couple of days and now it won't light up when I connect it to my rMBP. It's getting power ok and the pass-through USB ports (on the back are passing power). But when I connect to to my rMBP, the USB ports lose power (iphone stops charing and chirps) and the monitor is never recognized.
I fixed it one by unplugging the power plug on the rear of the monitor, then replugged it back in, but now that doesn't work either
I tried:
 restarting the mac
 shut down and restart
 PRAM reset
 both Thunderbolt ports
 all combinations of Mac power/monitor plug in
Anyone else?
Thank you.

One more symptom (yes, it's still dead) that I thought I'd share.
My Thunderbolt monitor passes power through to the connected MagSafe adapter no problem. It powers my MacBook fine, 100 percent of the time. But here's where it gets weird...
The USB ports on the rear pass power. I have a USB fan and a USB > Lightning adapter for my iPhone 5 plugged into the back of the monitor and both provide power -- UNTIL I plug the Thunderbolt plug into my rMBP13. As soon as I plug TB into my MBP, the USB ports on the rear lose power (fan turns off and iPhone stops charging). As soon as I unplug TB from my MBP the fan starts again and my MBP resumes charging (as noted by that distinctive chirp).
So I suspect that it's a defective monitor. It worked fine for about a week, then it was intermittant for about a week. Now the screen won't light up at all, and the USB pass-through ports are acting up too.
I think someone needs a trip to the genius bar. Which isn't trivial because it's mounted to a VESA adapter and an arm bolted to my desk.
(sigh)

HT2471 MacBook air is not connecting with my Thunderbolt monitor...should be easy fix but i cannot figure out

I have been using my MacBook Air with Thunderbolt monitor for a few months with no problems... Now I connected my laptop to my monitor and I am not getting a connection. Please help

It's possible that the W2 you used was set up with the EchoSign service. It allows you to draw a signature with a mouse. This is available as well with more recent versions of Reader (10.1+) if the form isn't Reader-enabled or secured. You will see this in the Sign panel when the document is opened in Reader.
You can otherwise get an EchoSign account and upload your document and send it to your customers through the EchoSign service. You can establish a free account to see how it works.

Thunderbolt monitor volume is low

I don't know what is going on, but my volume is fine on my MacBook Pro, but suddenly the volume on my Thunderbolt Monitor is not very loud, not matter what I do. I have verified in Sound that Output Volume is at Max for Diplay Audio. I have been to Audio Midi Setup and the bottom two sliders are at Maximum.
Who has a suggestion?

I just experienced this problem, and it was fixed by plugging in the usb cord from the display to the computer.

Thunderbolt monitor mail sounds

When I plug in my retina MBP to the 27" thunderbolt monitor, every mac mail sound since the last time it was plugged in plays in succession. Sometimes this is 5 mins of ding (incoming) & whoosh (outgoing) mail sounds. What a very peculiar bug.
Anyone else getting this?
I have read a few posts stating it was mountain lion bug that was fixed last month ( Aug 2012 ) however all of my devices are up to date and it is still happening.

David: Thanks for this info as I will try in future next time if needed.
I don't know if it began with new updates to quicktime or iTunes, or when Yasu Cleaner froze during cache cleaning, but after restarting,then had probs with Keychain access to mail not working along with sounds, then it got really messy! (It couldn't find keychains.login)
What I ended up doing and it now all works(sounds and keychains,etc) was:
-Thankfully I had backed up my keychain folder before all these problems, (all should do this if they haven't!) backup folder location:("~" is home folder)
(~/library/keychains folder)
-2nd went in same orig. area for keychains folder and deleted 2 files found in there ..one was some login and think other one said some microsoft certificates file
-3rd copied saved file from my BACKUPs folder("keychains folder") to original location
-4th restarted computer
-5th ran Disk Utility- repair permissions
Now: ALL SOUND BACK and ALL PASSWORDS in MAIL, and I didn't even have to re-enter them!

Possibly mundane Mini-DVI to VGA into an external monitor problem

Hi,
I've had a look over the interwebs regarding my problem and it seems as if it's not unusual to have external monitor problems but I'm not sure if mine is slightly different:
I had a perfectly working set up with my new Macbook (the white one, '06 model I believe), that was connected to my Hanns-G HU196D monitor via a mini-DVI to VGA adapter, no problems whatsoever. But for a couple of weeks now my Macbook just flickers a light blue colour, with nothing at all on the monitor, and my macbook is unusable until I remove the adapter. I've read about updating firmware but I can't see my desktop once the macbook is connected to the monitor so it's not possible to configure anything. I've read somewhere that my external monitor isn't compatible with this set up, but it was until a couple of weeks ago!
My Macbook's 4 months old now and since then I've bought a new mini-dvi to vga adapter and a new VGA cable, no connections seem loose on either mini-dvi port or my monitor's vga port.
Thanks if you can help!
Jack

You will need to use a mini Dvi-dvi and a dvi-svideo/rca adapter.
Joy joy hallelujah.
Pardon the sarcasm...I just wasted 3 hours of my life trying to sort the issue out.
Heard a KWORLD PlusTV PCTOTV Converter SA235 USB 2.0 Interface would sort the issue out for under 40$ but it's not Mac.
Hope that helps.

Daisy-Chain Thunderbolt Monitors

I have been having a lot of issues since purchasing two new thunderbolt displays. I mounted both displays on my office wall via VESA brackets. I was super happy with how they looked and how they were able to Daisy-Chain together making them the most beautiful full function docking station for my MacBook Pro. I hooked up my mac via the single thunderbolt cable and power cord from monitor 1 and turned on my Mac. As expected the two monitors came to life in dazzling fashion giving me 54in of usable space. My issues began after I disconnected my Mac to go to a meeting. When I returned and reconnected the power and thunderbolt cords and after the usual blinking of the monitors only the Mac and monitor number 1 worked. Monitor 2 (the one daisy-chained to number 1) would not turn on, 27in of blackness. I tried reconnecting, changing the order of the displays, rebooting, and even re-imaging; nothing worked. I Googled it and found a lot of issues that people were having with displays and thunderbolt drives but none offered a solution that worked. after a lot of research I was able to piece together what was happening and a fix that actually worked. The issue is the Thunderbolt ports and they way peripherals get assigned. So the first time I connected the monitors they worked great but when I went to a meeting and connected to a projector or went home and connected to my single thunderbolt monitor there the ports would get reconfigured to run the single monitor or projector. Macs use SMC (System Management Controller) to control many low level functions like lights, fans, power button, and ports. http://support.apple.com/kb/HT3964 Following the SMC reset fixes the port assignment issue and allows the Mac to recognize the daisy-chained monitor or drive. One additional tip is to plug in the power and thunderbolt cable before resetting the SMC. it is a simple keyboard procedure that is easy and works every time. I hoping a firmware update of SMC will make this fix obsolete but until then at least my $2500 display investment is paying off in a lot of beautiful useable space.

Please do not double post - it does not help and things can get very confusing, so I've asked the hosts to remove the duplicate.
Good luck!

Daisy Chain a second Monitor to Thunderbolt Monitor

I purchased a new Dell S2040L HDMI Monitor and I would like to Daisy Chain to my Thunderbolt. I plugged the Dell Monitor into the back of the Thunderbolt monitor and my Mac Book Pro (OX Version 10.9.4) will not reconize the Dell monitor as a second monitor. Is there a display setting that needs to be changed?

You could use a USB to DVI converter

but performance will be severly limited by USB and some functions won't work

Connet a thunderbolt monitor and min display port monitor to a mac mini

I have a new late 2012 Mac Mini. I also have an exisiting Apple mini display monitor and just got a new Apple thunderbolt monitor. How do I get these both to work with this Mac Mini so I can have dual monitors? I read something about an external thunderbolt drive. How would that work and what product should I buy that has all the ports on the back? Thank you for the help.

Unfortunately a Mini Displaport monitor will not work when connected via a Thunderbolt display. Nor will a Thunderbolt display work via a Mini Displayport monitor.
See http://support.apple.com/kb/HT5219
You could use a DVI or HDMI monitor in addition to the Thunderbolt display, or you could use two Thunderbolt displays. You could sell your old monitor and buy another new one.

Can the last link in a thunderbolt daisy-chain be a non-thunderbolt monitor using miniDisplay port?

Can the last link in a thunderbolt daisy-chain be a non-thunderbolt monitor, using miniDisplay port?
For example, Mac mini <--> external SSD <--> apple cinema display 30" (using miniDisplay port adaptor plugged into the SSD's second thunderbolt port)

for instance STAE122 or STAE 127?
FWIW, STAE129 is the current version TB adapter
that is self powered and has TB daisy chain port.
STAE122 and STAE127 are older versions and
not the current model, though there may be stock of
these around. As to whether this will solve your issue,
I don't know.
Can I trick the Mac under Bootcamp as OS to use HDMI for the monitor? Dell officially says that the monitor can only accept 1900x1080 over HDMI, but some have fiddled wth different computers with custom settings that worked with some Monitors but mostly under Linux and to Dell 2711.
The MacMini HDMI port is hardware limited to 1980x1200.
