Does the Mini Display port carry audio?

I am trying to setup a collaboration centre in my school where I would have 4 macbook pros attached to a TV. http://i53.tinypic.com/jkdduw.jpg
I was going to buy a KMV and Audio switch to connect all the laptops to the TV but then it occurred to me that the TV has 4 HDMI ports. HDMI carries audio... I found a mini display to HDMI adapter online.
Now I need to know if the Mini Display Port on the newest model of MacBook Pro 13" carries audio?
It is my understanding that the specs for Mini Display say that it is possible. The question is did apple implement it?
Does anyone know?

Yes - See Apple's document here.

Does the mini DVI port cary audio if using a Mini-DVI to HDMI Adapter?

Hello everyone,
I've heard it is possible for a DVI port to transmit audio data to a HDMI connection if a DVI to HDMI cable is used, which will allow the sending of both audio and video to your TV. see: http://en.wikipedia.org/wiki/DigitalVisualInterface
I'm assuming this is not possible using apples mini DVI port, but just wanted to check to make sure. My main goal is to get surround sound out of my powerbook. To do this by simply adding a Mini-DVI to HDMI Adapter would be GREAT!

Hi Jonathan,
I'm assuming this is not possible using apples mini DVI port
Yup, no audio, unfortunately. The audio will have to transmitted separately via the analog audio output.

Run MDP to HDMI for picture. Use a cable like this to run sound from your audio out on your Mac to your TV's audio in. That's about all you can do.

Does mini display port support audio to hdmi?

No, you need to run your audio separately from the headphone jack to an audio in port on the TV.

I have lost all sound on macbook pro 10.6 and in ITunes can no longer play any cinema or tv shows purchased. I believe it may have been caused by recent use of mini-display port Toslink Audio to the TV. What can be done?

I no longer have any sound on my macbookpro 10.6.8, not even beginning chime.
Furthermore, I find that I no longer have any images as well as no sound, from any
of my Itunes cinema, tv show purchases, etc.
I recently watched last week a couple of tv episodes through my TV
using a Mini Display Port + Toslink Audio purchased at Apple.
I use this device occasionally and haven't had any problems til now.
Any suggestions to right the problem?.

In System Preferences>Sound do you have your internal speakers set as the output source?
You may have toggled on optical output with the Toslink cable - check to see if there's a red light coming from the port. If so, quickly plug and unplug a set of headphones for a number of times to see if you can toggle the switch back from optical to the internal speakers.
Good luck,
Clinton

I have the mini display port cable to hdmi. When I connect I can get audio but on the video I get the display auro screen and can't get my actual display to show as that is not what shows on my display. How can I fix this?

There is a little white bar. When you have your TV connected, move the white bar to the other display. Your main desktop is now the TV screen

I think your Macbook came with a Mini DVI port instead of a Mini Display port.

Question when using the Mini Display Port.

Hello,
I just got my 27" Imac, and I was wondering what is the hotkey to switch between the mini display port and the normal desktop?
Am using a Mini Display to DVI adapter and I can't figure out how to switch between the video sources. Am trying to run my Ps3 off from my mac, any help on what the hotkey is would be wonderful.
I read some place that command+F2 is the hotkey used to switch between the port, but maybe you have to assign the hotkeys?
There have been people who have been able to use there systems this way, and Apple states the port is there for this purpose; Any light on this subject would be nice.

Welcome to the Apple Discussions!
You can only run your PS3 on the iMac's display if you have an adapter that turns the PS3's video signal into DisplayPort signaling. A mini-DisplayPort to DVI adapter is the wrong adapter to use. That adapter works in only one direction, from a device with m-DP output to a device with DVI input.
If your PS3 has DVI output then you need an adapter to convert the DVI to HDMI. Then you need a converter to convert the HDMI to m-DP. They run US$149.00. The best resolution that you can expect is 720p.

Then you can toggle using Command+F2.

Drag applications from your main desktop off the right side of the screen and they will appear on the TV. This is the extended desktop mode.

This article may provide some information about your Mini DisplayPort to AVI adapter. Have you tried to connect a different VGA monitor to your Macbook to see if you get the same results?

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.

How can I detect displays?
If the detect displays option is not available, hold down the Option key while you are in the Display pane.
How do I select additional resolutions on my display?
You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.
I hope this information helps ....

How can I get my 2010 macbook pro to send signal out through the mini display port?

First, what you said is contradictory. You say "can't get a video signal", then say"the Mac wallpaper is broadcast, the mouse pointer is visible". "No video signal" means an absolutely black,blank screen. It sounds like you have plenty of signal.
I am supposing what you are seeing is actually a blank desktop, which is to be expected if your settings are such that you are extending the desktop, instead of mirroring it.
Within the preference panes is a setting that allows you to change this. Open System Preferences, click Displays, and then click Arrangement. You will see that you are extending the desktop. Change that setting.

Can i connect thunderbolt duo hard drive to the mini display port of a late 2008 macbook pro which do not have thunderbolt port, but have mini display port.

hi, i have a late 2008 15 inch macbook pro, which have a mini display port.
I noticed that thunderbolt and mini display port looks a like. So, my question is :
can i connect thunderbolt duo hard drive to the mini display port of a late 2008 macbook pro which do not have thunderbolt port, but have mini display port.
thank you

ken94538,
no, you’d need a Thunderbolt-to-FireWire adapter or Thunderbolt-to-USB adapter to be able to access your Thunderbolt hard drive from your 2008 MacBook Pro.
