Connect to 2 external displays using 2 thunderbolt to hdmi cables
I have a new iMac which has 2 thunderbolt ports. I was told that I can add 2 displays using these ports with thunderbolt to hdmi cables. However when I do this only one screen connects. The other remains blank (and off).
Hello, I wonder if HDMI isn't the problem?
It's supposed to...
2nd Display Support:
Dual/Mirroring*
2nd Max. Resolution:
2560x1600 (x2)
Details:
*This model can simultaneously support two external displays up to 2560x1600 via Thunderbolt.

Do the monitors have anything besides HDMI?

How to connect imac to tv using thunderbolt to hdmi cable
I'm trying to connect my mid 2011 iMac to my tv. I have a thunderbolt to hdmi cable that I purchased. I connected the thunderbolt port to the iMac and connected the hdmi port to the tv. I turned on both devices and the tv is not getting the signal. What am I doing wrong? Any help would be greatly appreciated!
If you open the Displays preferences and do not see an Arrangement tab (or there is an Arrangement tab that shows only a single monitor) then there is something physically wrong with your connection.
Although I don't have thunderbolt, since you can plug mini-displayport into a TB socket, then like mini-displayport, they a a little sneaky in that you need to make sure the plug is fully seated in the socket.
If you do have an Arrangement tab, and it shows two screens, then click detect displays. Then click Gather Windows to bring the TV's Displays preferences on to your main screen. Set the proper resolution (probably 720p, 1080i, or 1080p). Set the refresh rate (probably 60Hz). You should see a picture at this point.
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.
Also, you need to set your Sound preferences to output to the HDMI connection. -
I'm on a Macbook Pro (Mid-2012) on Mac OS X 10.8.3 (currently downloading the update to 8.4). When I plug in my Mini Displayport to VGA adapter to my Mac, the screen flickers blue for a second and the Display Settings window detects the other monitor and allows me to rearrange the screen, but it does not project anything onto the other monitor. However, I tried connecting an Apple Thunderbolt Monitor to this computer today, and it worked. This wasn't a problem before, as I was able to connect this Mac to other LCD projects before. Furthermore, I don't think it's an issue with the adapter either because it's relatively new. I also tried plugging in the adapter of another Mac (which was working fine) into my Mac, but it didn't work either.
Here's what I've tried:
1. Restarting the computer with everything plugged in
2. Pressing Command + F1 when it's plugged
Any advice would be helpful!Hi lancekatigbak,

Can I use my macbook pro mid 2012 as an external display using thunderbolt port
Hi,
I want to use my macbook pro (mid 2012) screen as an external display for a raspberry pi using a HDMI to Thunderbolt cable, via the thunderbolt port on the macbook pro. Would this be possible? Can the macbook pro's thunder bolt port act as an input and is any additional software required?
I look forward to hearing from you.
Thanks in advance!Welcome to Apple Support Communities
You are referring to Target Display mode. Target Display mode can only be used in 27-inch iMacs and iMacs with Thunderbolt, not MacBooks Pro > http://support.apple.com/kb/PH11302
Unfortunately, you can't use the MacBook Pro as a display. It doesn't support the monitor mode -
Connecting Macbook Pro to LCD Display using MiniDVI to HDMI Cable
I currently use an LCD TV to play movies from my Macbook Pro via the MiniDVI - HDMI cable. At the moment I just connect everything up and then use the Mirror Display in the arrangement settings. So my laptop screen is the same as my LCD TV screen. What I want to be able to do though is watch the movie on the LCD TV and also use the laptop to go on the internet, is this possible???
Yes. Turn off mirroring in the "Arrangement" tab of "Displays" system preference.

Can i connect an external display using HD3000 after the discrete gpu has stopped working?
Say for some reason the HD 6490m is fried and I can only use the HD 3000; will I be able to connect the laptop to an external 1080p display via thunderbolt?
Technically it should work, i know. But i've tried it with gfxCardStatus 2.3 and nothing happens until i allow the radeon to work. My question is: after the amd stops working, will the computer allow the HD 3000 to connect to an external display? Is there some kind of limitation so that only the 6490m can use the thunderbolt port?
Early 2011 15" MBP running 10.9.4
i7 2635qm
Cheers!Thanks for the fast reply!
So i assume this is because Apple uses a custom processor or because of the motherboard that inhibits it somehow, right? I'm asking that because some hd3000 chips in other systems are able to support a second display.
Anyway, thanks a lot. I will be careful not to lose the amd then -
I got the following message after the crash, it happens a few times a day, my system is the base with 16gb ram late 2013 15" macbook pro retina. it only happens when i am connected to an external display, I do have a converter from vga to displayport. also, i run 4 different browsers in incognito mode as i do web testing and also have about 30 tabs open and excel and a few other apps open, not sure if this is what makes it happen or if it is the external display? it is under warranty, so if you see anything below that may relate to the hardware i can bring it in and get it fixed.

X250 connected to 3 external displays
Hi, Is it possible to have the X250 drive 3 external displays using the dock? Can I just connect all three of the external monitors directly to the dock or do I have to daisy chain the monitors using display port?I do not intend to use the laptop lcd while the machine is docked. Thanks
This is really disappointing. Lenovo is explicitly advertising that T420 is capable of quad-display setup using only digital connections. I hope it can be fixed with a driver patch but seems very unlikely.

My Macbook (2009 White) Has had water spilled onto it, it all works apart from the screen. When connected to an external display it works fine, just not on the Macbook itself. Does anyone know how to fix this?
Take it to Apple and ask them to fix the physical damage the water caused.

I have my mac air hooked to the tv using thunderbolt and HDMI
I have my mac air hooked to the tv using thunderbolt and HDMI the background screen and screen saver are the only things that will appear, but no icon's and cursor what I'm i missing?
That's called the "extended desktop mode". Your screen is logically extended to the right (by default). Drag an application off the right side of your MBair screen and it'll appear on the TV.
You can also toggle between extended desktop and mirror mode by pressing CMD F1.
Visit all the settings in System Preferences > Displays > Arrangement tab.

Connecting devices for display using Thunderbolt to Mini-DVI
Hello.
Background
I purchased an Apple Thunderbolt Display, but it will not arrive for 6 weeks. So I want to determine if there's a solution that will allow me to connect a Mac mini to an older iMac (details of both below) until the display arrives.
Device details
iMac, Mid-2007 (model ID: iMac7,1), which includes a Mini-DVI port
Mac mini, Mid-2011/server (model ID: Macmini5,3), which includes a Thunderbolt port
Question
Since devices don't have similar ports, is there a way to connect the two so that I can I use the iMac as a display for the Mac mini? Specifically, is there a cable or a cable and adapter together that can make this work?
Alternatively, are there any other solutions?
Thank you.I do not believe your model supports using the monitor as an external display. This was a feature introduced only in the recent iMac models.
-
I have used different VGA to mini port adaptors, different VGA cables and connected them to different external monitors and prjectors but the same thing happens. I am starting to think there may be a problem with the macbook itself however, when i have used a HDMI lead and adaptor to external monitors the external display is fine.
