No sound via mini display to HDMI connector

Hi all,
I have the i7 8G ram version of the X1 Carbon (UK version) and love it. The only issue I have with it is in relation to the mini display port. I use a lot of HDMI equipment so immediately bought the mini display to HDMI connector from Grifin, see http://store.griffintechnology.com/video-display-converter but whilst video exports fine no sound is being output via the HDMI cable and end up sound via the X1 speakers which are great for personal use but useless in a large room full of people.
I already contacted Griffin support and they quickly referred me to Lenovo.
All help much appreciated.
Ben
Solved!
Go to Solution.

BenEadir,
When you have a video or sound file playing, go to Control Panel, Sounds, Manage Audio Devices.
Then when you are in Manage Audio Devices, you will se a list of devices and the external device/TV your mini display port is connected to as one of the options. Just choose the one you want and set it as your default audio device and the sound should automatically go to the selected device.
Let me know if this works for you.
Thank you for being a part of the Lenovo Family,
Catie

While we all have MacBooks in this forum most of us don’t run Lion. There's a Lion Support Community where everybody has Lion. You should also post this question there to increase your chances of getting an answer. Lion seems to have problems with external monitors. https://discussions.apple.com/community/mac_os/mac_os_x_v10.7_lion

Connect MacBook Pro 3,1 to hdmi tv via mini-display port

How do I connect my MacBook Pro 3,1 (2007) to an hdmi port on a LCD TV using the mini-display
port on my Mac? I am running Snow Leopard 10.6.8.
I have connected a mini-display to hdmi connector into an HDMI port on the TV. I've watched lots of youtube videos
on how to do this (apparently with newer Macs), but when I go to 'system preferences/displays', I have no options like 'extended TV'
or 'mirroring' and I have no resolution choices with a 'p' behind it. I've tried 'command-F1' as someone
suggested to make it 'mirror' and nothing happens.

IMac 24" (early 2009) Mini Display to HDMI possible?

As there is no Mini Display to HDMI adapter available as of yet I tried to connect a new 24" iMac (early 2009) to a Sharp LCD TV via: Mini Display --> DVI --> HDMI.
Although the iMac recognizes the Sharp and switches resolution automatically (I also tried every other available resolution) the TV screen stays black (HDMI is EXT 5, but I also tried the other EXTs).
I googled and it seems to me that our setup works for some people with some LCD TVs (Sharp too).
Any thoughts where the problem here could be?

Open System Preferences Displays pane Display tab. If there are two displays being recognized, there should also be an Arrangement tab, but stay on the Display tab.
Click the button that says +Gather Windows+. Although you cannot see the image on the TV (since you say it is black), you should now get the control window for that TV display on your iMac's display.
Try making adjustments to the resolution and refresh rate to see if you can get a response on the TV's screen.

Actually you need a Thunderbolt to HDMI adapter. It will carry both audio and video.
This one will work: Mini DisplayPort | Thunderbolt® to HDMI® Adapter w/ Audio Support

Getting no sound from TV after connecting Macair via mini DP to HDMI port....pls help

I've tried connecting my 2011 Macair to my LED tv via mini DP to HDMI port. The video works fine but there is no sound. I tried opening network preferences and went to the sound section but it does not show my TV to be selected as an output option. Please help!!!!!!

Did you try on another device, like a computer monitor? To verify the problem is not with the adapter or cable.
Off course you switched on the external screen using WinKey+P?

update: my background screen from the computer is now on the TV, but not the movie that I am playing.

I just hooked my macbook up to my sony xbr6 tv via mini-dv to hdmi. I had to go into system preferences, then displays. A sony display window appeared, then I went to arrangements, and clicked on mirror displays, and it appeared....I'm still trying to figure out how to get the sound through my tv...I thought I might get sound thru the hdmi cable, but I think I might have to use an rca cable...

I've got a MacBook pro 15' running 10.6.6. I want to use an external monitor for my graphic design work running Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing.

I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing. I also tried a Mini Display to VGA lead and that wasn't much better. I tried all variations of resolutions in System prefs - Displays but nothing helped. Am I getting something wrong? Thanks all.

In addition to pixel density, you are up against the translation driver card in the TV.
If you read the fine print of computer-resolution-capability in the TV user guide, you will see a chart as tall as the manual page. At the top is the smallest resolution capable, at the bottom is the full use of the 1080p in the TV.
Mac falls into the top 25% of the page, maxing out at 1366x768 often. This is because the TV control card is expected to do too much of the work, but is not designed for computer-monitor processing.
I looked at the resolution charts on 2 TVs before deciding to buy a 1080p LCD monitor that has a TV interface/connector. Computer monitor first, TV second. But the thing is only 27 in. Good thing TV is not as important to me as it is to others.

Mini Display to VGA adapter stopped. The Mini Display to HDMI is still working fine. How´s that possible?

The mini display to VGA adapter had stopped, whinle the Mini Display to HDMI keeps working fine. The minid display to VGA adapter was replaced and the VGA cable as well, and the problem is the same. This test was made with two diferent monitors with VGA entries. How´s that possible to happen? Is that a configuration trouble in the MBP?

The Apple´s customer support gave us the solution for this problem:
SMC reset
PRAM reset
The VGA adapter return to work properly aflter this procedure.

Mini Display to HDMI adapter causing screen to go white/ gray

I recently purchased a mini display to hdmi adapter to hook my macbook pro up to my samsung led tv.
At first it worked great but after a few mins of inactivity both screens would go white or light gray and the macbook was totally unresponsive.
I pressed buttons, moved the mouse and nothing….I had to hard shut off and then restart the macbook to get the screens to come back up. I thought it might have been just a glitch but then it happened 2 more times all within the span of 2-3 hours. (keep in mind this is the first time ive ever used this adapter and have had no prior issues with my macbook)
I have no idea what could cause this type of issue.
Any suggestions or ideas on what could cause this? is it my settings or my computer?
I looked up the manual for my macbook online and my settings match what it says they should be… Im at a loss.
Any suggestions would be greatly appreciated. Thank you.

* my connection is macbook pro - mini display to hdmi adapter - hdmi to hdmi cord - Samsung LED tv.

Mini display to hdmi adapter problem

Hi,
When I connected my mini display to hdmi adapter to hdmi, and hdmi cable to my ASUS PA238QR monitor, my early 2011 MBP 13" detects the monitor, but the monitor shows "hdmi no signal".
I tried unplugging everything, including the adapter and hdmi, but to no avail. I tried putting my computer to sleep, and waking it up, still, nothing seemed to be the cause of the problem.
I read through some old discussion on this issue, and nobody seems to have a solid solution besides purchasing another adapter.
I tried booting into win7 and still, the monitor shows "hdmi no signal".
I am 100% sure my monitor and hdmi works becuase when I used other laptops it's fine.
Thus, I'm suspecting it's the mini display to hdmi adapter's problem.
Is there a way I can make sure that my macbook pro is outputting the signal?
Any recommendation or advises are welcomed. Thanks for reading.

If you've an HDMI port on your television, you could always try that.
I've used this adapter from Monoprice successfully - not bad for under $7.
Give your TV a try - if no go, then you'll know that it's an adapter problem.
Good luck,
Clinton

The Best Mini Display Port HDMI Adapter?

I am looking for recommendations on a good Mini Display Port HDMI Adapter for my Macbook Pro 2011 Sandy Bridge. I have gone through about 4 adapters in the past year due to the adapters become unresponsive after 2 or 3 months. I use my Macbook heavily on external monitors for my work (averaging 7 hours or more a day between various monitors).
I can rule out the HDMI wire itself not being the cause of the problem but the adapters have been a huge miss and drain on cash this year. If anyone who is also a heavy user can point me in the direction of a durable adapter I would be very grateful.

I always recommend monopriice.com for cables and adapters.
Mini DisplayPort | Thunderbolt® to HDMI® Adapter w/ Audio Support
But all these adapters are in the form of "pigtails" and no matter where you get them the strain relief and the cables can fatigue and break from constant bending or pulling (doesn't help your macbook socket any either).
Maybe you should order a bunch. They are cheaper that way at monoprice.
Another possibility might be you trying a mini displayport to HDMI cable. No adapter.
Kanex Mini DisplayPort to HDMI Cable with Audio Support (10 ft.)
But of course you could get about 6 adapters for the price of that one cable!

Why does my screen turn blue and freeze every time i try to plug in my 'mini display to hdmi' cable into my thunderbolt port in order to use an external monitor?

why does my screen turn blue and freeze every time i try to plug in my 'mini display to hdmi' cable into my thunderbolt port in order to use an external monitor? it only works if i turn the computer on with it already plugged in.

Do you have gfxCardStatus installed? Is your monitor set to "Integrated" or "Discrete". You want it set to Discrete to drive the external HDMI display.
Try resetting the PRAM and SMC
<About NVRAM and PRAM>
<Intel-based Macs: Resetting the System Management Controller (SMC)>
Are you sure you have a good miniDisplayPort to HDMI cable?
Do you have another HDMI display you can test against (your neighbor's HDMI capable TV).
Do you have friend that can test the cable using their Mac and maybe their TV or a monitor that has HDMI input.

HDTV won't display as mirror or extra display via mini-dvi to HDMI

Hi
I have a MacBook running 10.5.7 connected to a 1080P-capable Toshishba TV (model 42XV555). I also tried this with 10.5.6 with same results.
They are connected via a "shuttlez" mini-dvi to hdmi dongle and then via a "wegi" hdmi to hmdi cable.
The TV has three HDMI inputs, one designated for computer input via HDMI with a separate input for analogue sound.
THE MB recognizes the TV and displays a separate Toshiba-specific control panel with display control panel is up. It defaults to 1600x90 and 60Hz. The Macbook adjusts every time the tv is connected - there is communication - flashing screen, MB screen re-adjusts.
S-video works fine, via mini-dvi to s-video donglr, then svideo cable.
It has worked twice with the MB and connected with HDMI - just twice. I have spent hour after hour tweaking resolutions, re-booting, changing cables, HDMI ports on the TV etc! When it worked I could mirror and use the screen as a separate, larger display. It worked in clam-shell mode too.
My question is - are there any know problems getting this combination to work (ie MB, mini-dvi to HDMI)? It can work but I am missing some knowledge on the exact combination required.
What are the optimum settings to have this TV display HD from the MB, or come to that any HD 1080p-capable TV??

I'm attempting to connect my MB to a plasma 50 inch Panasonic TV, and am about to purchase the necessary cables from www.monoprice.com.
I've discovered so far that the HDMI connection directly between the MB and the TV (using the appropriate mini DVI adapter of course - product # 4852 at monochrome.com and an Apple HDMI cable which I'll return to get a better price at monochrome) transmits only video/pictures but not audio.
So far, an old, short RCA (red/white) 2-way audio test cable (again using the appropriate adapter to connect to the headphone jack on the MB) does not transmit audio directly to the TV.
1) Could audio be transmitted from the MB to the TV using a "Coax (RCA) to Optical Toslink Digital Audio Converter" (product ID # 2947 at www.monochrome.com) to connect directly to the TV (in which case, what digital audio cable would I need to connect the converter to the TV)? And if so, would it be stereo or mono?
OR...
2) Should I wait until I get my Onkyo surround sound system (later this week) to see if the RCA cable will transmit directly from the MB to the sound system?
Thanks.
