Forgets my display arrangement on 2nd thunderbolt port

I have a new MBP retina and I am getting some strange display issues. I have 2 thunderbolt displays and also use the laptop display. When I use the second thunderbolt port my display configuration isnt the same as the other port. I fix one and then the other is messed up. Does anyone know how I can fix this?

same laptop, i can get native resolution on 2 apple 27 displays so unsure why you're not able to
try both pram and smc resets and test again
also is it detecting both displays as monitors or TVs?

2nd thunderbolt port has limited resolution

Hi, I've got a late 2013 15" retina with a discrete graphics card. For some reason, when I connect external monitors to the 2nd thunderbolt port (the one closest to the USB port). I can't get resolution greater than 1920*1080 on an external monitor (Dell U2713HM). On the other port I get a full 2650x1440. Is this a known problem that I've just discovered?
It happens with both minidisplayport to displayport, and minidisplayport to DVI connectors.
I've tried to sort things out with switchResX, but at 2650x1440 it just squeezes the display with black bars at the top and bottom.
any ideas or help would be great.
Thank you

Mavericks forgetting my display arrangement

I have a MacBook Pro with three external displays - two of which are connected via USB/DisplayLink adapter. Since upgrading to Mavericks, my system forgets the display arrangement every time I reboot. It defaults back to "mirroring" which I have to fix and then the order of the monitors is wrong which I also have to fix. This is quite annoying.
On top of that, I have the issues that others have mentioned - screen flickering when opening the Mail application, lagging mouse pointer, etc.
According to DisplayLink, this needs to be fixed in an OSX update. Does anyone know if there are plans for this and/or is there a workaround?
(and yes, I do have the new beta driver for DisplayLink)

I found this from another thread in Mountain Lion:

Hello everyone,
While I fear everyone may have moved on to the ten grand can by this point, I am still trying to get this issue with the older Mac Pro resolved. I have some exciting news for you all!
About a week ago, I had had enough, so I unplugged my Mac Pro, and carried it 10 blocks down to the Apple Store in Charleston, SC, where I was graciously greeted by the genius team whom I had previously spoke to about the problem. We did some testing in the store and were in fact able to replicate the problem. The genius spent some time looking through Apple's logs of cases and support documentation, but was unable to find anything relating to this issue. The next step he then told me, was to escalate the issue to the engineering department. I was told I would hear a response back in about a week. To my amazement, it was less than 48 hours later. I got a call from the same guy at the local Apple store. He told me that he spoke to the engineering team and said this, "this is a software or firmware bug that has recently been brought to light. The issue is related to the order in which the displays are powered on/brought out of sleep." I was told the best thing for me to do next, was to head over to apple.com/feedback and fill out a software bug feature request. I did so, and I would suggest that all of you, still have this issue do the same as well!
I will certainly keep you all informed of any further developments.

Thunderbolt display : Video input into thunderbolt port?

Hi,
I've got two major questions about the Apple thunderbolt Display :
- Can the thunderbolt port located on the back of the display be used as an video input?
. Is it possible to plug a second mac equiped with a thunderbolt port to this port?
. If it's possible, how does the display manage to switch between the two macs?
- Is it possible to plug an external HDMI source such as Blueray reader, Play station, etc. with an "hdmi - mini display port" cable?
Thank you very much for your answers !

I can confirm that the Thunderbolt Display will work when plugged in to the 2011 MacBook Pro 15" and a 2011 Mac Mini Server connected via Apple's Thunderbolt cable. When both systems are connected to the monitor, the display will always prefer the system connected to its display port, when it sleeps or is powered down, the other system detects the available display and connects to it automatically. I can't imagine a more ideal sinerio!
Thank you Apple!

How to connect two DVI screens to Thunderbolt Display's Thunderbolt Port?

Hi everyone,
I have a new MBP and an external Thunderbolt Display. The Thunderbolt Display itself has a Thunderbolt port, and I was wondering if there is anyway to connect to DVI screens to that. My goal is to have the Thunderbolt Display and 2 x 24" Samsung DVI screens connected to my MBP.
Alternatively, has anyone had success using a third party device like the Matrox 2 go to drive multiple monitors from the usb port?
Thanks,
Dave.

You could try a TB>DVI adapter (here's one from Monoprice) but I don't know that it will work - I'm thinking that you could have at least one of your Samsung displays use it. You may also want to see if you can find a HDMI>DVI adapter for your second Samsung display - something like this?
I know that I've seen three monitor set-ups on YouTube - but I'm not sure what was connected to what. Easy enough to daisy-chain ATDs but it gets a bit tougher when utilizing HDMI ports, etc., and I'm not sure about the GPUs ability to drive all three displays.
Oops - sorry - strike that second paragraph - I thought that you were running a Retina display MBP...

Daisy Chain 2 cinema displays to thunderbolt port on iMac?

Presently I have an iMac (mid 2011). I am running 2 cinema displays thru my 2 thunderbolt ports on my iMac. Is it possible to daisy chain these 2 additional displays to save a thunderbolt port? If so, how would be greatly appreciated.

Only Thunderbolt displays are capable of being daisy chained.
If you had one Thunderbolt Display and a Cinema Display then you could put the Thunderbolt Display first and then connect the Cinema Display into it, but it cannot be done with two Cinema Displays.

Using thunderbolt port disables wifi in Boot Camp

I am running Windows 7 Ultimate x64 on an early 2012 Macbook Pro. When I plug in my new LaCie Rugged 1TB external drive to the thunderbolt port, my wifi is disabled.
The drive shows up and works correctly, but no wifi. If I reboot in Mac OS, the wifi is works fine. I only use Windows however and this drive is for Lightroom storage, and I need wifi. I have seen many posts where users have found an external display connected to the thunderbolt port (using Mac OS) disables wifi and the solution was to change the wireless channel in the wifi utility. I have tried every channel on my Airport Extreme with no success. Very strange that I can get wifi with external drive connected using Mac OS but not in Boot Camp. I need this drive connected to the thunderbolt port to free up the USB ports for my card readers and other drives. The wifi is fine as long as I don't use the thunderbolt port, so this issue is isolated to the thunderbolt port and Boot Camp. Any suggestions, please?

Unfortunately no. I'm learning slowly that nothing much gets done by Apple for issues that require Apple's intervention, i.e. this would appear that the solution would require Apple updating the Thunderbolt Drivers for Bootcamp within an updated Bootcamp drivers update (I have Bootcamp version 5 which I dowloaded from Apples download section and appears still to be the most current).
I have reported this a few times on the Apple feedback page, but that has never ever eventually returned a solution either (just falls on deaf ears), maybe that rout has returned results for some lucky users but never ever set the ball rolling for a solution to many issues I have put forward on the feedback system.
I must admit that Windows support had surprised me recently; I have an attached device to my MacBook Pro that when booting in Windows Bootcamp appeared to lose some of it's functionality when I logged into my usual Windows account (within Bootcamp), yet if I logged into Windows as the 'root/super user' the functionality was all there. Upon posting this on the Microsoft forums I was taken aback that not only did a Microsoft professional answer by query (no charge involved) but they gave me a procedure that corrected the problem. On the basis of this I believe Apple really need to see the bigger picture and at the very, very least analyze and read the stuff posted in their forums, maybe occasionally replying but if not so then to at least read up on the issues and secretly act on them. I'm fast going of Apple having joined their band wagon ten years ago (from PC).
On the other hand Apple probably think it's fun for me to tiresomely and relentlessly have to keep changing picture mode settings every single time I boot up between OS X and Bootcamp, which can be many times a day - trust me it is not fun but extremely frustrating.

Thunderbolt port to Mini Display Port to HDMI problem

Ok.. I figured it out (after reading another post of 44 pages of solutions/non-solutions and complaints starting back to 2009 and trying some) It seems as though a simple fix was missing.... I did this and it works just fine...
I have a 27' imac. I used the Thunderbolt port on the back to a MDP to a HDMI to my 55" Vizio HD 1080p TV. It didn't work until......
I called my Boeing engineer son-in-law (who is a very part time mac person (but very smart!) and he had me go to (SEE steps below!)........
I did this and it works just fine...
HERE IT IS STEP BY STEP!!!
1.Open SYSTEM PREFFERRENCES click DISPLAYS. A window opens that will say your mac on the top of the window (mine said- iMac).
2.Then....click ARRANGEMENT (there will be 2 little blue screens inside--1 portrait and 1 landscape view) and check MIRROR DISPLAYS.
3.Now a second window opens with the name of your other display (mine said- VZ55.....which is my TV) (the two little blue screens will now be overlapping).
4.Then go to DISPLAYS on same window and choose your RESOLUTION.
5.Now arrow pack on window to SYSTEM PREFFERRENCES
6.Click SOUND and click on whatever your other display is (mine was VZ55....).
7.Choose your resolution (mine was 1080p) and ****POOF**** there it was.... my computer on my TV!!!
WALLA!
I hope this will help a lot of you! Good Luck All!

Anyone else having trouble connecting MBP with thunderbolt port (TBp) and 27"iMac with mini display port (MDp)

I have a 27" Imac.i7 with mini displayport and MBP13 i5 with thunderbolt port. Some time ago I tried to connect my old MBP with miniDP to The 27"iMac I Failed so did the apple centre they refunded cable costs and said I'd be contacted by Cupertino. That was 9 months ago, now replaced MBP with 13 inch(**** I can use my iMac as display!). Does not work phoned Fast Lane very helpful guy called JIM emailed me some software/firmware update links. Still no display linking. One of the links was for a couple of updates for a TBp equiped 27" iMac mine is only MDp equiped. Failing to find any MDp updates in apple support. Anyone have any Ideas! My lad has a later 27"i5 he uses Xbox 360 no problem on his but it wont look at my MBP.
Beginning to feel like some of the kit that went with a fully loaded 5500 worked eventually. Computer and FM radio, Photography kit fine, video capture audio capture forget it. Too many crashes and resets made it impractical.

HT202801 Cannot connect 2nd Thunderbolt Display or HDMI TV

Hi,
I can't seem to get my 2nd Thunderbolt Display or HDMI TV to work or be recognized on my MacPro. I do have my primary Thunderbolt display working. I went through the setup options that was on the how to article to set it up, and still nothing. Under About this Mac, it only recognizes the primary display as well. Any suggestions? Thanks

When I unplugged my primary monitor, the second one did not come on. I did go through all of the thunderbolt ports with the primary monitor and all of them had a signal to it. I unplugged my second displays power and plugged it back in, then plugged it back into the MacPro and it came on. Now if I can only figure out the HDMI tv signal I will be all set. Thank you all for your help.

I have a Macbook Pro 13.3 i5 w/ no hdmi port. How can I connect my Mac to TV to watch video, photo ? Is the Thunderbolt port a mini display port where I can use a mini display port to HDMI cable? If not, what are my options??

I have a Macbook pro 13.3 w/ i5 that has no hdmi port. I want to be able to connect the Mac to my TV set to watch Video, Photos and files from Mac to TV.
Is the Thunderbolt port similar to a display port or mini display port? Can I use thunderbolt port to connect thru a mini displayport to HDMI cable or converter?
Been trying to locate a USB to HDMI cable or converter (at a reasonable price) but all I found is a displayport or mini displayport to HDMI cable/converter.
What other options are available ?
Thanks a lot for your assistance.

Thunderbolt uses a Mini DisplayPort adapter to send video and audio to HDMI. Here's some on Amazon http://www.amazon.com/s/ref=nb_sb_ss_c_2_8?url=search-alias%3Dcomputers&field-ke ywords=mini+displayport+to+hdmi&sprefix=mini+dis%2Caps%2C249#/ref=nb_sb_noss?ur l =search-alias%3Dcomputers&field-keywords=mini+displayport+to+hdmi+with+audio&rh = n%3A172282%2Cn%3A!493964%2Cn%3A541966%2Ck%3Amini+displayport+to+hdmi+with+audio

Mini Display port DVI adapter not working on Thunderbolt Port

For some time I've been using a mini display port to DVI adapter on an slightly older MBP to connect to my HD TV. I recently purchased a MBP with a Thunderbolt port and when I try to connect it to my TV via my mini-display-port-DVI adapter things are not working properly. The MBP is seeing the Philips TV but it isn't listing all the display modes and I'm not able to send any video to it. Does the Thunderbolt port require a new display port to DVI adapter?

Let me be clearer; I've got the MDP-DVI adapter connected to a cable that is DVI on one end and HDMI on the other. I've got both laptops so I can compare side by side. I plug in the MDP-DVI adapter to the old laptop and all works well; I plug it into the new laptop and while the laptop does see the TV, the display modes for it are all 1080p which is wrong I don't see any desktop image on the TV unlike when I plug it into the older laptop. This is very disappointing as I expect things to just work with Apple products.

Connecting Cinema Display with mini display port to macbook pro with thunderbolt port

I am trying to connect a 27" cinema display (2010) that has a mini display port cable out of the back, into my macbook pro (2013) with thunderbolt ports. The mini display port cord fits into the thunderbolt port on the Macbook Pro, however the macbook pro does not detect the cinema display and the cinema display does not have any picture on the screen. The USB plugs in fine and sound comes out, and I have the adapter for the magsafe to magsafe 2 and that works fine, it just the actual display. Any help would be appreciated!
Thanks!

Hello mmholt,
Welcome to Apple Support Communities.
It sounds like there’s no video on an Apple Cinema Display that’s connected to your MacBook Pro, and you’re wondering if the configuration is supported. It is supported, take a look at the article linked below for more information.
Thunderbolt ports and displays: Frequently asked questions (FAQ) - Apple Support
1. Can I connect a Mini DisplayPort monitor or monitor using a Mini DisplayPort adapter to a Thunderbolt port on my Thunderbolt-equipped Mac?
Yes. A Mini DisplayPort display or a display connecting with a Mini DisplayPort to VGA, DVI, or HDMI adapter will work just like it was connecting to a Mini DisplayPort connector when plugging in directly to the Thunderbolt connector on your Apple computer. Click here for more information on Mini DisplayPort connections and adapters.
Also, this article provides a lot of great information and troubleshooting tips that will resolve most issues related to video external displays.

My Thunderbolt-port equipped 15" Macbook Pro (Early 2011) works with other monitors but not with my Thunderbolt Display.

I just got a thunderbolt monitor and excitedly, I plugged my early 2011 thunderbolt port equipped 15" Macbook Pro (running 10.8.2) into it and... no image on the monitor.
Ok, so I know that the TB display works because I plugged a mid-2012 13" Macbook Pro into it (running 10.7.5) and it works perfectly. In fact, I'm using it to type this message right now.
Other details:
- in both the displays preference pane and about this mac/system info, the 15" mbp recognizes the display, yet... no picture either clamshell open or closed. restarted with it plugged in and not plugged in, no difference. also? sound comes through the monitor.
- ALSO, i plugged in a mini displayport monitor into the 15" port, and it displayed fine, so the port seems to be doing something.
see my conundrum?

It should just work - if it's not working with your 2011 model (works just fine with my 15" late 2011, right out of the box) I would get in touch with AppleCare as soon as possible and see what the senior techs may have to say...
