Display using and HDMI Cable

I'm having trouble connecting my MacBook Pro to my TV using an HDMI cable. I know I have the right cable and I know I am plugging it in correctly. However, I cannot find the right setting for my screen to display on the TV. I've tried changing the display resolution in system preferences, but I don't know which is the correct one to choose.

Apple lays out the requirements for audio over HDMI below. Verify that your Mac model is new enough, otherwise it will be too old to send audio over HDMI. If it's too old, you have to use a separate audio cable.
About Mini DisplayPort to HDMI adapters
You can certainly check the audio output settings in the Sound system preference and also in the Audio MIDI Setup utility, but it is just as important to make sure your TV is set to play back audio from the exact HDMI port that the Mac cable is plugged into.

I am trying to connect mbp to tv using mini display port and HDMI cable TVtuned tocorrect port as shows Mac wallpaper (purple star scene) but does not show what is on MBP. What can I try so that I can see mbp display on TV?

What do I needto do to connect a tv as an external display for my mbp using a mini display port to hdmi cable. I have tried display without success. tv is receiving a signal as displays apples default wallpaper when connected but nothing from screen of mbp.

Soundls like it is working. Try dragging a window on the MBP to the edge of the screen and see if it appears on the TV.
There are two ways to set up the TV one is to mirror the MBP display and the other is to be an extension of the MBP's screen.

Help using a mini display port to HDMI cable with MacBook Air and TV

Hi, Apple gurus. I need help setting up my MacBook Air to my Vizio TV using a mini display port to HDMI cable that I just purchased on Amazon.
And here's info about my MacBook Air:
In the Amazon reviews, someone posted the following how-tos, which aren't working for me:
1. Plug in both ends, mini display port on your macbook and the HDMI on any available port on your LCD.
2. Go to upper left Apple menu and scroll down to system preference. Or use your FINDER from the dock, go to applications, then system preference.
3. Click on Displays
4. Click on DETECT DISPLAY
5. A similar screen pops up with name of your LCD, mine says SONY LCD, click on ARRANGEMENT
6. Click the box that says MIRROR DISPLAYS.
7. Go back into system preferences and go to SOUNDS which is located under HARDWARE.
8. Click on OUTPUT, then select HDMI, which should be listed next to your LCD name.
I ran into trouble at step #4. My MacBook Air doesn't list the option of "detecting display." I do, however, have the box mentioned in step #6, "Show mirroring options in the menu bar when available."
Regarding step #8, HDMI didn't appear in the list — I only see "internal speakers."
So, what am I doing wrong? Or, did I buy the wrong cable?
Thanks in advance for your help!

Or you need to get an appropriate adaptor. The Griffin adaptor sold on Apple's Online Store will work with a standard HDMI cable.

HT201177 no audio when using a mini display port to HDMI cable to TV on my Macbook pro

no audio when using a mini display port to HDMI cable to TV on my Macbook pro. can only see the video

I keep saying this over and over, in the hope that people who do a search will find it. Apple cannot possibly test for or be reponsible for the bazillion combinations of adapter, cables, and TV's out there. The only monitors that are 100% guaranteed to work with the MacBook Pro are the Cinema Displays and Thunderbolt Displays, because, they're made by Apple. They're expensive, but they work perfectly.
My guess is that you bought a cheap MDP to HDMI cable, or have a defective one. From my reading of these boards over the past few months, cheap cables have a high failure rate. And the regular priced ones have only a slightly less of one. Try a new one. Make sure you do not damage the Thunderbolt port.

I would like to connect my Apple TV to my receiver using an HDMI cable and pass thru dolby digital. I do not have optical inputs on my receiver.

I want to connect my Apple TV to my receiver using an HDMI cable. This should allow me to pass thru high definition video and simultaneously decode Dolby Digital material with an HDMI connection from my receiver to my TV without the use of an optical cable (my receiver does not have an optical input). I am unable to decode 5.1 material and don't understand why this is not working. In the audio setting I have Dolby Digital output turned on.

Welcome to the Apple Community.
Are you sure the content you are playing has Dolby Digital.

to get to the Detect Displays button you have to hold down the Option key and the button appears.

I will be using a HDMI cable to connect an Apple TV box and a Comcast cable TV box to my TV. My TV has only one HDMI port.
To do this I will need a 2x1 HDMI splitter or a 2x1 HDMI auto switch (preferred).
?Is there any Apple TV HDMI port voltage?
When using a HDMI auto switch to connect two devices to a HDMI TV, the
Auto switch cable box only works for components that do not output continuous voltage over HDMI port when turned off.
Do you know of any other solutions? Componets? Actual expierances?

Cable : HDMI switches expand the number of available HDMI ports on a high definition television allowing connection of cable boxes, Blu-ray players, and game consoles. A side benefit is that cable clutter is also eliminated by running a single HDMI cable to your HDTV from a switch and relocating the HDMI ports to a concealed location. The problem with most HDMI switches is that you have to either get up to push a button, or hunt for the remote control, to switch sources. The true mark of any great switching component is an ability to perform its function and remain transparent in its operation. This automatic HDMI switch is a plug-and-play away from offering everything you are looking for in an HDMI switch. Select a single output from up to three devices for signal delivery to your HDTV. Smart operation provides complete control for connect-and-forget operation. Powering on a device gives it output priority over the other devices. By powering down the device in use, output priority is returned to the last powered on device. Note: Auto switch function only works for components that do not output continuous voltage over HDMI port when turned off.

Hi Erico,
I tried what you said again but without success. I even updated the driver so that that audio driver is the same as the graphics driver i.e.. NVIDIA but this has not helped either:
Do you have any other ideas?
Many many thanks,

Mini-display port to hdmi cable not working consistently

I have a MacBook Pro (15-inch, Early 2011) 2GHz Intel Core i7, 4GB, Intel/ATI combo video - Yosemite 10.10.2. I purchased the monoprice 15" mini-display port to hdmi cable and it worked perfectly for about 1 month or 2. Now when i plug in the cable, the MBP doesn't detect that I have a second display connected at all. I assumed the cable died so I tested it on my iMac. The cable worked. Also when I try my Monoprice 15" mini-displayport to VGA cable, that works on my MacBook Pro. I can't figure out what is causing my MacBook Pro to "forget" how to detect this cable. Anyone out there experiencing the same? I tried PRAM reset to no avail. Any suggestions would be great.

Hello David,
If you are having issues using your external display with your MacBook Pro, check the article below to continue your troubleshooting with resetting the SMC as well. Work your way down the article if you still are having issues after that.

Mini Display Port To HDMI Cable Not Working?

Dear members,
i have a mid 2010 13" macbook pro which i have been using a mini display port to HDMI cable which also carries audio for for years now.
I went to use it last night and have to pull the cable out and plug it in a few times to get it to work.
Tonight it just wont work at all no matter how many times i pull the cable out and plug it in again!
Before i use to just connect it and boom, screen would go off then on and it would also mirror on to my TV.
My TV is a 32" Toshiba TV, i tested the HDMI ports, working fine. The mini display port to HDMI cable works fine on my 42" TV downstairs.
Any one know of a fix for this?
Thanks.

How can I play music on my macbook pro (OSX Lion) through a Pioneer receiver. I've connected them with a mini display port to HDMI cable with audio support bought at the Apple Store, but there's no sound coming through. thanks

How can I play music on my macbook pro (OSX Lion) through a Pioneer receiver? I've connected them with a mini display port to HDMI cable with audio support bought at the Apple Store, but there's no sound coming through. There are 4 HDMI-in ports on the receiver - BD, DVD, DVR/BDR and audio. In my system preferences for sound, the receiver doesn't show up as an output option. Can anyone please advise. (ps, this is my first time posting a question, so I hope I can find your answers!) thanks, JP downunder

For sound, try the audio output port and connecting to the RCA audio input ports on your Pioneer receiver. Use something like this:

Where's the appleTV selection on the iTunes homepage. need to reload my appletv using the HDMI cable

Can't find the AppleTV icon on the iTunes page. Trying to reload using the HDMI cable method (crashed). What am I missing? I need to reload from iTunes.

Have you seen this?
Apple TV (2nd and 3rd generation): Restoring your Apple TV - Apple Support
When you say the remote is not working, does the light on AppleTV flicker when you use the remote but nothing happens?
If so hold Menu and left arrow/rewind keys TOGETHER for over 6 seconds and see if you get an unlinked chain appearing on screen- if you do it may now work.

Connecting Micro USB and HDMI cables at the same time

I need to be able to use a Micro USB and HDMI cable at the same time to configure ATV to connect to WPA2-Enterprise secure WiFi network. I'm using Apple Configurator to do this. Because of the poor hardware design, it isn't possible to connect both the Micro USB and HDMI cables at the same time. Does anyone have a worrkaround to resolving this issue?
I saw a similar post about this problem in the forums dating back to April 2013 with no real solution. It's been over a year now and I'm hoping someone has found a workaround to this problem. I have a bunch of ATVs that I need to configure for our classrooms.
Thanks!
MG

How to connect a MBP to a BENQ external monitor using a HDMI cable and a HDMI to mini display adapter?

Hi, I have just bought a brand new HDMI cable and HDMI to minidisplay adapter and tried to connect my Macbook Pro up. The external display knows it is there but it is not getting any signal. I have tried on another TV and it also says no signal and I also tried using another Mac but it still didn't work.
Can anyone help?

In some versions of Mac OS X, with the Displays pane open, holding the Option key will show the detect displays button in the lower right.
I am using OS X Mavericks. Where did the Detect Displays button go?
You can find the Detect Displays button in the Displays section of System Preferences. Once there, press and hold the Option key to see the Detect Displays button in the lower-right corner. You can click this button to manually detect another display.
Another technique is to sleep and wake your computer, which will send the detect display sequence as well.
