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

MacBook Pro 9,1 External Monitor Blanks Out?

I have a 15-inch, Mid 2012 MacBook Pro with a 2.3 GHz i7 processor, which I purchased last December. For some reason my external monitors blank out about 1-3 times per day. As far as I can tell the symptons are not reproducable. It just seems to randomly happen.
Has anyone else had this problem and if so, what was the solution?
Thanks!

Are you sure it is not a hardware problem? A bad cable or a poor connection?
I would try this after eliminating hardware causes.
Go to System Preferences / Displays. Verify the settings are correct, and correct or not change them arbitrarily - just move the settings back and forth - and then set them back where you want them.
Now reset the PRAM:
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

How can I export slideshows created in Aperture v3.3.2 from Mid-2009 MacBook Pro-17 to blank DVDs?

(Fifth futile attempt in two hours, before I learned there was a Post webpage – I’m new to ApSuppCom - and after I learned that I am not allowed to update previous content, so I had to back out, make a few changes, and start over.) How can I export slideshows created in Aperture v3.3.2 (complete with superimposed captions and music tracks) from Mid-2009 MacBook Pro-17 to blank DVDs ? (Some other specs: Mac OS Lion 10.7.5; Capacity 499.5 GB; Processor 2.8 GHz Intel Core 2 Duo; Memory 4GB 1067 MHz DDR3; Graphics NVIDIA GeForce 9400M 256MB)
I cannot do a copy (export) without various error messages appearing and the inevitable stoppage occurring. Always with the DVD Video Player final message reading, “Supported disc not available.” Advisors and Mac Geniuses at local Apple Stores have told me to try Roxio Toast. When I visited the Roxio website, and found numerous other company products, the descriptions all seemed to suggest that most of the apps shown can easily export videos to DVDs, but nothing was said about finished digital slide shows being exported. At future events soon, I hope to be handing out these finished DVDs (free) to the people in them. Any help will be greatly appreciated. A.Z.

How can I export slideshows created in Aperture v3.3.2 (complete with superimposed captions and music tracks) from Mid-2009 MacBook Pro-17 to blank DVDs ?
Aperture cannot burn slideshows to a DVD. It only can export a video of your slideshow.
In Aperture 3 you use the "Export" button in Aperture's slideshow project to render a video to a folder on your disk.
Then you use iDVD or another program to burn a video DVD.
I cannot do a copy (export) without various error messages appearing and the inevitable stoppage occurring. Always with the DVD Video Player final message reading, “Supported disc not available.”
Could you please describe the exact steps that are causing these error messages?
How are you exporting your slideshow from Aperture? Which settings are you using? And how are you importing the video to iDVD or Toast to burn a video DVD?

When I am listening to the radio (streaming through itunes) my macbook pro will log me out, quitting all the applications I have running (often firefox, word processing, itunes, etc). Why?

When I am listening to the radio (streaming through itunes) my macbook pro will log me out, quitting all the applications I have running (often firefox, word processing, itunes, etc). Why?
It's very frustrating and I don't understand why it happens. It might happen other times, but I notice it the most when I'm streaming the radio through itunes, though I think it's also happened when I'm streaming music or shows from NPR, so I don't actually know if it's an itunes thing, or an internet thing? Or just my computer being stupid? But how can I fix it?
Thanks!

My best guess at this point is a problem wwith 10.5.8
It seems clear to me that sometimes, seemingly randomly, software will access the video card (flash player, quicktime, Safari's HTML5 video player, etc) and it will cause a freeze and then log out.
However - it could just be video card + processor under load.
This didnt happen before 10.5.8 and I'm thinking it's not the new 27" display causing the issue.
I'm going to attempt to find time to revert back to 10.5.0 and then combo update back up to 10.5.7 which may be difficult as our IT is remote and we don't have access to Snow Leopard discs.
I may just have to bring my own in.

Macbook pro dvd drive spits out fresh blank dvd

A fine lense cloth (for cleaning eye glasses) wrapped around a flat piece of credit card shaped plastic gently inserted and brushed once to the left side seemed to capture plenty of dust from my late 2008 MacBook Pro's Superdrive. Now DVDs work again and stay in the drive.
Sometimes the simplest solutions are the best.

Macbook Pro Thunderbolt and HDMI displays switch on wake up

Hi there,
Currently using a late 2013 15" Macbook Pro., latest version of Mavericks. I have one display hooked up through Thunderbolt->DVI, with a second set up through HDMI->DVI.
There seems to be an issue where on waking the monitors up from sleep mode (about 10 minutes inactivity time) the displays will turn on, immediately go black (inlcuding the Macbook Pro screen), and then switch such that all windows on one are now on the other.
I can't really repliate this, as it seems to just happen randomly. All I can say in my detective work, is that the HDMI->DVI hooked-up monitor tends to take a little more time to turn on after sleep, whereas the Thunderbolt->DVI monitor comes up immediately.
Any help would be greatly appreciated.
Thanks.

I've noticed that the HDMI connection seems to lag the Thunderbolt on wake as well. I haven't had the switching issue, though. I use my Thunderbolt display as the primary (menu bar in the preferences) - maybe try doing that if you're using your HDMI out as the primary.
You can always try resetting the SMC and PRAM as well.

Linking MacBook Pro to monitor

Hi,
I have just purchased a Dell U2410 to connect to my MacBook Pro.
Please can anyone advise the best connector to buy and whether there's anything I need to know to set it up. Would like to setup the laptop screen as a second screen if possible.
Not sure if this is the correct community to post into but assumed it was OK as it would use the Thunderbolt connection.
Many thanks, Karen

Hi Karen:
I too bought the Dell u2410 to use with my MacBook Pro 13" late 2011.
There is a way to adjust the brightness of the monitor, but you have to be clairvoyant or just lucky to know it. ;-p
At the end of my post I have an explanation for the way to do it.
Basically, Dell monitor control industrial design #FAIL. You have to know to hover over the correct, tiny blue light first to activate the controls.
/rant/ They don't look like buttons, you're not used to touching a single light LED to activate something, they don't appear pushable, the first one has a more important function and so is different but doesn't look or feel obviously different from the other little lights, there are two ways of reading the row (upward vs. downward), and it's different from many other displays. In short, you gain nothing, they save a little on mechanical parts, and you're confused and spend $300 of billable time figuring all this out./rant/ (*the first light does stay lit a tad longer, but that's a wee bit subtle to be discoverable the first few times)
When I first I hooked up the monitor, all the feedback from the display was a little floating message for "no VGA connection". I read over the setup sheet, which was no help. Plus the useful info is printed in 2-point type. After 2 hours of mystified fumbling all around the front, sides, top, bottom, and rear of the monitor face, googling, flipping around Settings on the MBP, etc., I read a post on the Dell support forum for a fellow sufferer that held the clue.
Settings/Options location:
Basically, on the display frame, just above the on/off button (which is a real, pushable button praise god), there is a series of 5 tiny blue lights spaced about 1/2" apart. If you happen to fumble lightly over the bottom one and not on any of the other blue light dots first, and not too hard or it activates and vanishes again, this displays the monitor controls. [whew!]
So:
1) hover over or lightly touch the bottom tiny blue light to show/hide monitor settings, then
2) you should see a little vertical panel appear nearby on the display
3) the other little blue lights let you choose from Presets, Brightness, Inputs, and Menu.
4) Inputs lets you tell the monitor which cable input you're using
5) Brightness/Contrast has controls so you can adjust the levels
6) Menu contains loads of useful settings, including: color profile, gamma (set it to Mac instead of PC), presets for different needs, Zoom, PIP, and customizable stuff.
Once I adjusted a bunch of stuff under the Menu, the monitor didn't clash so much or burn my eyes out compared with the MBP. I recommend it.
I conclude that Menu used to be the only touchlight/button, which would be much easier; it includes everything the other buttons control, and the other lights were probably added to regain the old quick-access brightness etc.
(btw I am using a miniDisplayport to Displayport cable, 3rd party from Monoprice, which someone else recommended in another post. not yet sure if it's the best choice although it works fine)

I broke my macbook pro's monitor

And im waiting for a month. Shortly , i will go to my university. I have doubts can i go there with my macbook or not. Is there anyone can inform me ? How long to take a monitor component ?

You can also ask the company if they have your machine in stock. You may want to get a portable LCD screen to go with you separately and just attach it to the MacBook Pro. Preferably a screen that supports DVI or better. If it is back at the factory being matched up with a part, see if you can get it recalled faster so you can get the external screen added yourself. 2011 and later MacBook Pros all support Thunderbolt, mini-Displayport, and mini-Displayport to HDMI or DVI adapters. Granted it won't be as elegant as being attached, but that way you might not be waiting as long for a part that might be hard to find. Especially if it is out of normal warranty.

Macbook Pro 2011 DVI HDMI out does not work with TV when the power cable is connected

My Macbook Pro (Early 2011) DVI HDMI out does not work with TV when the power cable is connected. If get the blue screen and then can use the macbook but nothing is displayed on the TV. If i go into display I can see that there are two screens but nothing displayed on the TV. If i take the power cable out at this point the TV shows the second desktop as expected. If i then reconnect the cable, the screen flickers, as though it is being affected by the power cable, and the screen goes blank on the TV. Only if i remove the DVI cable do i get the blue screen again. If i remove the power cable and reconnect it will do it every single time, so i cannot see it being a TV issue or a minor glitch.
I have had this working previously but at the minute it seems to not be playing ball....any thoughts
Thanks
Dan

BUMP
Any ideas?

I just bought a new external monitor (ASUS), and I have DVI adapter plug. When I connect it with my Macbook pro - the monitor remain black (even tho it is 'on')

I just bought a new external monitor (ASUS), and it have DVI and VGA plugs. I bought the DVI adapter to connect with my macbook pro laptop. But the external monitor remain black… so I turn it off then turn it back on, it said "No VGA signal". Does it means I have to use VGA adapter instead? I am not sure how it work, I am very new to it… I hope you can help me out!
Thanks!

Macbook Pro DVI and Video Out woes..

Hey, this seems to be a known issue although specifics are difficult to nail down. I've had my macbook pro since shortly after they were launched and been using the DVI - S-video adapter since day one, and it's been outputting to all TVs with no problem.
I recently got a nice overtime payment from work and decided to treat myself to an external 24" display, was very pleased with it when it arrived. Plugged it in downstairs, and ran it for a few hours, putting it through its paces - worked great.
Decided to move the whole arrangement upstairs and 'no input signal' said the monitor, the MBP just didn't detect anything in the displays. The built-in display did it's blue screen when the cable was plugged in, so it's definitely detecting something.. The monitor is connected via a DVI-D single-link cable. I've confirmed that both cable and monitor work using a different computer.
So after this happened, I decided to try plugging it into a TV again to see if the S-video out worked and although Displays picks up the TV and everything is as usual, nothing is shown on the screen.
Any suggestions would be very welcome before I get my hammer and remodel my computer!
Anyone else suffering from something similar to this?
The monitor is a 24" Yuraku YV24WBH1.
Cheers.
PS I've tried booting from the install CD, two versions of XP bootcamp (one with standard drivers, one with Catalyst, and the computer's old HD with 10.4 installed on it - no joy with any)

Another update, I did some research and it seems that ATI are cagily admitting to the fact that there might be a problem with the X-series;
http://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&questio nID=26586
http://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&questio nID=21266
http://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&questio nID=25682
You'll notice that ATI tell you to contact the manufacturer of your computer if the graphics are integrated into the motherboard. Like with Apple. Much joy to be had there.
I phoned their technical support and got talking with a specialist who was mystified and suggested 'turning off the airport'.
Also, it seems that Apple rather significantly "underclocked" the GPUs in their macbook pros;

http://forums.macrumors.com/showthread.php?t=306024
http://forums.macrumors.com/showthread.php?t=194647
Could be running the GPUs are running on a lower voltage and maybe they're not working right, or the signal isn't stable enough to pick up an EDID? It seems to be quite a mystery. Perhaps the osx86 community will have some tricks up their sleaves for twisting the x1600's arm. Still doesn't explain why the monitor worked that one time.
This probably isn't an issue for anyone who doesn't want to plug their laptop into an external display, but I suspect it's a widespread problem just waiting to rear its ugly head, especially as HDTVs become more ubiquitous.
Anyone else struggling with external display devices, or with solutions, I'd appreciate your input.

MacBook Pro to monitor?

So... How does one connect a MacBook Pro to a monitor, without HAVING to spend $1000 on a Thunderbolt Display?! It's frustrating, because I can't seem to find an adapter for DVI to the Thunderbolt port.
Thanks.

MiniDisplayPort-to-? ... fill in the ? with VGA or DVI or HDMI. About $30.
Plugs into the Thundebolt port.
Attach to any monitor ... Samsumg, Acer, LG, etc.
Two modes for display: Mirror (same image both displays, resolution limited to lower-max of the two so an HD monitor will be limited to the internal display resolution) or Extended (select the resolution for each of the internal and external).

Macbook Pro WEAK monitor hinge AFTER apple repair! PLEASE help!

Hey everyone, I am using a 2010 MBP with a 15" hi res display. I had the computer for 3 months with no problems and then the display broke (wouldnt turn on) so apple replaced it. Once they replaced it, i noticed the display was not as strong. To help you all understand this better, let me give you some background information. I am a DJ and music producer and I play at various venues quite often. The problem I am having, is when my computer is on my laptop stand, and the bass hits from the venues sound system, the monitor will wobble down when placed on my laptop stand (http://www.safecomputingtips.com/blog/wp-content/uploads/2008/11/irizer-laptop-s tand.jpg). This NEVER happened before the display was replaced, nor does it happen on my 13" 2009 MBP. To get a sense of what im talking about, if you watch the end of this video (http://www.youtube.com/watch?v=hmN9p9z3KgA) it demonstrates how the screen will fall down with just gravity. While no one would ever use a computer like that, while it is on the laptop stand its position is very similar. When he holds the macbook body vertical, it causes the screen to fall down with gravity. Before my macbook was replaced, it NEVER did that. My 2009 MBP has had TONS of wear and tear and doesnt do that. I went into the apple store and tried it on EVERY macbook pro in the store, 13 15 and 17 inch models, NONE of them fell with gravity. This started happening when i got the screen replaced. I have gone into the apple store and have had the display replaced for weak hinges 2 or 3 times now, and every time i get it back it is no better. My computer was out of repair yesterday, I took it into apple tonight (20 mins ago) and I was told by a manager that this is within "normal" specs for a "normal" user. Which is true, this wouldnt bother anyone who doesnt use a laptop stand and plays in clubs; but i do. He told me there is nothing he can do, and that I would just have to deal with it (of course he said it much nicer). What i dont understand is that I paid 2,800 for a computer that worked PERFECTLY until the screen died, and once it was replaced due to APPLES fault, now i must deal with a problem caused originally by apple. When I DJ with my 2009 model, no problems. My thought process is that maybe because the original screen is not on the unit, the replacement may not be as sturdy because it wasnt built with the unit itself. For example, my 09 mbp has had no replairs and its fine. The models in the store i assume have had no display repairs, and theyre all fine. The manager agreed that my hinge was weaker than the rest of the stores' models, but even though it was weaker it was within "normal specs", and he wouldnt budge. I'm sure a new unit that has been built together will fix this problem, but he would not give me a new unit. Is there ANYTHING I can do to help this? I am going to a different apple store tomorrow and hope the manager is a bit more understanding in the fact that not all apple computers are put through "normal" use and therefore should not be judged with "normal" specs. When my computer was new it NEVER ever ever did this, and I feel like I bought applecare for that exact reason, so that for at least 3 year i have the computer I bought. Any any any help would be greatly appreciated, I am 19 going and paying my way through school and if i didnt have to pay for school I would just say screw it and I would buy another unit, but i cant. Thanks for reading this, i really appreciate it.

Unfortunately, spoke way to early. The fan issue is still a big problem. From the second the machine is turned on, the fan cranks up. Frankly, I think this is overheating the machine to some extent (running the fan at max speeds when it's not even warm). Additionally, the noise caused by this has only gotten worse, and now it is even making a "whistling sound." Looks like I'm going to be making the trek to the Genious Bar, but based on comments by others on this issue I am not optimistic about a fix.

Macbook pro thunderbolt 2011 won't detect display

I am working on a Macbook Pro, October, 2011 model with a thunderbolt port. I have now gone through two thunderbolt to HDMI cables and neither was able to detect my display, which is a Sony Bravia. Should I throw in the towel and buy a $50 (rip-off) cable from Apple, or could it possibly be that my port is faulty? Anyone with a similiar problem?

No, don't buy expensive cables. Do you have a url (link) to the cable you are using?
On what basis do you think that your computer doesn't detect your TV?
If you opened Displays system preferences, click Detect Displays. Is there an Arrangement tab and an does it show two monitors? If not, then there is indeed a physical problem Make sure the cable is fully seated in the HDMI on the TV and the TB socket on the computer and also make sure your TV is set to take input from the HDMI input port you connected the cable to.
If the Arrangement tab is there and shows two screens click Gather Windows. This should bring the Displays preference window for the TV on to your main screen. Then set the resolution (probably 720p, 1080i, or 1080p) and refresh rate (probably 60Hz). At this point you should see a picture on your TV.
You may have to play the underscan/overscan settings on your TV and the displays prefs for the TV if the picture is too small or larger for the TV screen. If Sony's haven't changed they may call it "full pixel".

Macbook Pro and Monitor help - Now won't work??

Ok so I have been using my i7 Macbook Pro 15" with a Dell Monitor fine.. but then started to get the odd flickers.. I was told this was a Mac issue and many many people had this..
Now when I plug in, my Monitor defaults to the orange standby light and it won't come on at all when connected to the Mac??!
I am using DVI with an Apple Thunderbolt adaptor so i can use the Thunderbolt connection on this newer MBP.
I took the monitor off the Mac and connected via DVI to a PC Laptop and the Monitor sprang into life and works great!!!
So I know its not the Monitor
Any solution to making this work again on the Mac????

Hi,
Could you please confirm the CC application you are using.
It would be great if you post a screenshot of the problem.
