2 Monitors via 2 Thunderbolt-to-DVI adapters to Macbook pro Retina.

I own a 2012 Macbook pro retina, and I'm looking to buy two non-apple monitors. Now I've been wondering whether it would be possible to use my 2 thunderbolt ports and attach each with a thunderbolt-to-DVI adapter, and thereby connect the 2 separate external non-apple Monitors.

Yes, that would work just fine.

What model MacBook Pro?
The mini display port on earlier Apple computers only support video. See:
About Mini DisplayPort to HDMI adapters
Also, if you go to System Preferences>Sounds>Output do y see HDMI or Min displayport as an Audio out option?

Thunderbolt audio distortion during heavy Thunderbolt hard drive activity on MacBook Pro Retina 15 2012

I have a 2012 MacBook Pro Retina connected to a Thunderbolt Display, with Thunderbolt hard drives attached to that. Whenever I'm doing a big copy, or a Time Machine backup, any audio being played through the speakers becomes heavily distorted. If I switch to internal speakers, it's fine (but obviously not high-quality). As soon as drive activity quiets down, audio is fine again.
Anyone else having this problem and/or know of a fix? It's super aggravating to have to change speaker settings every hour when my backup kicks off!
Thanks!

I believe this issue is caused by bad ground coupling between the two devices, some of the induced charge can spark between connectors in the thunderbolt port causing computer to basicly freeze.
To solve this issue try touching the connectors outside metal part to your macbooks body first to discharge it, then while plugging int the connector do it at slight angle so the metal of the connector touches Mac's body.
This method has been working for me.

HT5219 How would I connect dual monitors and also a firewire cable? Macbook Pro (Retina)

Currently I am using two thunderbolt to DVI connectors for the dual monitors, but I am left without any firewire cable connection for my audio interface. THe only adaptor I found was another thunderbolt to firewire, but since I already used these two ports, I am left with no options. I haven't been able to find any usb to firewire cable connections.
Are there any other adapators/ports I can use that I am not aware of?

Something like this at US$300:

2 External DVI Displays on MacBook Pro Retina Display

Hello,
I have seen all the 3 external display setups for the RMBP and all that stuff going around the internet showing how thunderbolt displays and HDMI can be used together.
I have also read about how daisychaining works for 2 apple thunderbolt displays.
But i was wondering if i can use two external displays on my retina MBP buy using a mini DP to DVI converter. Then attaching a DVI splitter to this converter and connecting the two ends of the DVI splitter to 2 DVI displays.
This is setup we use at my work. The splitter is nothing fancy. It connects to the dvi output on our PC computers and we connect it to our two monitors. to get dual displays.
Or will this not work and I will have to use both my thunderbolt ports to run 2 mini DP to DVI converters? (slash will that work?)
Advice will be very much appreciated!

You can, but you need additional hardware to do so:

IPod touch (4th gen.) doesn't charge via USB 3.0 ports in MacBook Pro Retina Display

Is the MBP on (not sleeping)?

Connecting 2013 Macbook Retina 15" to Acer B286 HK monitor via Thunderbolt.

I have a 2013 Macbook Retina 15" and would like to connect an Acer B286 HK monitor via Thunderbolt/MiniDisplayPort.
I am using the standard Apple Thunderbolt cable, but it does not work. The monitor complains about "No signal".

Short answer: I have this exact configuration, and yes, the newest rMBP 15" w/Nvidia card will drive the UP3214Q over HDMI at 4k and 30Hz. It will drive it as a separate desktop with the laptop open, and it will drive it as the sole display -- either way works fine.
Longer answer: You should be aware of 2 things (that I wish I had been more aware of before purchasing the monitor)
1) If you are used to 60Hz or higher, the 30Hz limitation over HDMI is noticable, even in day-to-day productivity work. The mouse lag is very noticable and annoying to me.
2) Scaling/HiDPI support [the way the integrated retina display works] is virtually nonexistant at the resolution you'd want to run it at. What this means is that you either run the monitor at a lower resolution (and everything is blurry), or you run it at full resolution and everything (menu, dock, fonts, etc) is extremely small. You can use SwitchResX to enable scaling support at odd resolutions (for instance, I've successfully gotten HiDPI/scaling to run at 1920x1200 and 2048x1080, with black bars at the edges), but it's not an ideal resolution for this size monitor. I want to match the TB display resolution (2560x1440) in HiDPI mode, but I've been unable to get it working after hacking away at it for 2 days.
I'm hoping that Apple will fix these limitations. Multiple people have reported that MST over DP1.2 works on the same hardware if you boot into Windows, so the hardware support is there -- it just needs to be enabled in the drivers by Apple. Whether they actually will or not is anyone's guess. In the meantime I (and many others) are in limbo wondering if we should return these 4k displays, or keep them and hope "proper" support comes. Since it's not a specifically advertised capability, Apple isn't under any obligation, but I think there's more than a few people hoping that Apple does right by the users and enables the full functionality that the hardware supports.

How to get new Macbook Pro Retina (late 2013) to detect external monitor via HDMI?

Hi everyone, this is my first Mac and for the most part it's been really, really wonderful.
This is my first major glitch: I cannot get it to detect my external display: It is an ASUS PA248Q, manufactured Aug 2012.
The HDMI cable according to my Amazon history is at least 1.3c from 2010, "Fanatic Digital Imperial Series Gold-Plated HDMI Cable (6 feet)".
It works with perfectly connecting an AmazonTV box to an old Samsung TV, with vivid clarity, unlike our cableTV signal.
Just in case, I have a new HDMI cable on order, which claims to be of newest standards.
The Macbook Pro Retina (late 2013) has the standard Intel Iris from the Haswell chips, as well as Nvidia GT 750M, the latter which I don't think has been used yet.
The ASUS display says: HDMI NO SIGNAL.
I have tried shutting them down and replugging the cable. I don't know what the ideal order is. The Macbook Pro is plugged into AC power, as suggested.
In System Preferences>Display, I press the Option key to select "Detect Displays" option (seriously unintuitive).
I have also tried resetting the NVRAM:
I shut the machine down. Pressed the power button, then quickly held the quadruplet: Option-Command-P-R (a double handful) and waited for the machine to chime a 2nd time. Tried to detect external display no luck.
Next, I reset the SMC:
I shut the machine down. Then I pressed Shift-Control-Option-Power for about 5 to 10s. Then I turned on the machine normally.
NVRAM & SMC steps were from an old youtube video, as the instructions I had did not explain how to do so clearly.
Please let me know if I"m doing something wrong.
Seems so exorbitant to pay $350 for Apple Care; that's a the cost for a whole new cheap laptop.
I will search the forums again. If anyone answers this, thank so much!

Hello there, willr314.
It sounds like you've covered most of the practical steps found in this Knowledge Base article:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573#1
No video or no signal, image distortion, "snow," or flickering
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
The article does offer some additional links and recommendations as well:

2 monitors on MacBook Pro (Retina) using Thunderbolt and HDMI ports?

I would like to buy a MacBook Pro with a Retina display. I want to attach 2 external monitors and Ethernet. I need to use one Thunderbolt port to attach to my (wired) ethernet.
Can I attach 2 monitors to a MacBook Pro (Retina) using
1) a mini display port to DVI adapter
2) a HDMI to DVI adapter?

Yes, it is possible to run 3 monitors at once on the Retina MacBook Pro (2 connected over Thunderbolt and one over HDMI).
Displays used in picture below:
Retina on laptop @ “best for Retina”
iMac used as a display @ 2560 x 1440 via Thunderbolt
iMac used as a display @ 2560 x 1440 via Thunderbolt/DisplayPort
LG monitor @ 1920 x 1200 via HDMI
Hope this answers your question.

Hello, I have a Macbook pro retina-2013. About Mavericks I could set my 4K monitor via HDMI on 2560x1440. This I can not get through at Yosemite. Can someone help me there?

Hello, I have a macbook pro retina-2013.
About Mavericks I could set my 4K monitor via HDMI on 2560x1440.
This I can not get through at Yosemite. Can someone help me there?

They really pushed that it would all work great! Has anyone had the same struggle? Are there any step-by-step instructions to get linked up?
Call Verizon's wireless tech support & explain your problem to them. They will provide "step-by-step" instructions over the phone.
Take notes too!
TIP: If you do call & don't want to go through all those darn promps, when you initially call, just don't say anything. The automatic voice will then say, "will connect you to a service rep."

Macbook Pro Retina: can anyone help me with running 2 extended desktop DVIs?

I know I need 2 thunderbolt to DVI adapters for this. In the UK these are £25 each, but the MiniDisplayPort to DVI adapters which look the same are very much cheaper .....
http://www.amazon.com/DisplayPort-Female-Adapter-Macbook-Laptop/dp/B003BHHIA4/re f=sr_1_1?s=electronics&ie=UTF8&qid=1359830910&sr=1-1&keywords=minidisplayport+to +DVI
They look the same as thunderbolt to DVIs but is there a difference? Anybody know if the thunderbolt to DVI is an ACTIVE adapter, which means the cheaper versions won't work?
Secondly, I've read scary stuff here from people who think their thunderbolt to DVI fried their monitors. Is there any evidence which supports this?
Does anyone out there use two extended desktop DVIs on a daily basis with a Pro Retina? Any tips or things I should know?

I suggest you buy the Apple TB/MDP to DVI adapters as I have tried another brand and it dod not work. That was on a late 15" 2011 model, YMMV.
Second I have never heard of a Apple TB/MDP to DVI adapter ever frying a monitor of any make or model.
Please post references to this claim.
May be possible with a poorly desinged adapter with some of the TB power output being cross linked to one of the DVI pins/connectors. But still doubtful.

MacBook Pro Retina hangs on startup when connected to Thunderbolt Display

I have a MacBook Pro Retina and it's basically almost always connected to my Thunderbolt Display. Each time I start it up, I open the MacBook just slightly and press the power button - and almost instantly the MacBook goes ontop the startup Login screen and at this point is where I close the MacBook and login through the Thunderbolt Display.
Since last night for the very first time - My MacBook Pro hangs on a white screen and takes a long time before going to the Login screen. I've tried to swith the Thunderbolt Display off from the mains - I've also tried to boot up my MacBook on it's own without it being connected to the Thunderbold Display and all is fine (it almost immediatelly shows the Apple logo and then staright onto the Login screen then BUT as explained, as soon as the MacBook is connected to the Thunderbolt Display and I power it up - it hangs on a white screen for about 30 - 60 seconds before it goes to the login screen!
I have no idea how from one day to the next this could happen? Perhaps it's some Apple updates I've made recently which I cant really recall because I usually just update software when required to do so.
Hoping anyone can help.
