Q: Mini display port to HDMI problem

Let me start by saying I'm using a 15" MBP.
Went to Frys, picked up a Inland MiniDP to HDMI, grabbed a HDMI cable I had laying around, plugged it into my Panasonic Elite receiver, set the scaling on the Mac and no problems. Well no problem except for no audio even with things plugged in correctly and the audio switching to headphones. I'm thinking it's my receiver not liking the HDMI/RCA audio combination.

I've found over the years that Monoprice has great cables, their electronics are, IMHO, iffy.

I use a mini plug to RCA adapter and hook that up from the headphone port on the Mac to the reciever. I don't think the sound works through the HDMI cable with macs. Hope that helps

Hello guys. The solution to this problem is very simple. All you have to do is connect the HDMI to the TV, then the HDMI to the HDMI to mini display adapter and plug it into the mini display port. You can do all this while the TV and Comp are on. You should get picture straight away. Then go onto your settings menu and go to sound. Next select the output tab at the top and you will see there is now your TV in the list, select the TV. That's it. The sound will now come from the TV via the HDMI cable. When you unplug the cable the HDMI option in the sound menu disappears and the comp automatically selects the internal speakers. Hope this helps.

I just wanted to add my experience with de MDP > HDMI problems.
Really hope to find an answer here!

I have 2 MacBook Pro's. 1 15" early 2009 (10.5.8) and 1 13" late 2010 (10.6.5)

I use the same MDP > HDMI adapter, whenever i unplug the HDMI cable from my ps3 and plug it into the 13" Macbook it always works, no exception. So I'm sure the adapter works fine.

However when I want to connect my 15" (older) Macbook it never works, VERY FRUSTRATING! The mac screen only flickers blue, but my plasma tv stays black (no signal). Also in system preferences I can't select mirroring/refresh rate/720/1080 since there is no display detected!

My question: How can i get the 15" to work?

This worked for me too.

Just check the "show displays" box and everything works all of a sudden.

Throwing a large (in example 1920x1200) resolution on a small TV just isn't going to work in most cases. The TV will often go black or flash an LED light to signify something is wrong...

Also using a MINI DisplayPort to DVI converter and then a DVI to HDMI converter is DOWNRIGHT SILLY.

The solution is to change the resolution of your Mac to something your TV can handle!

-System Preferences
-Displays
-Change your resolution to something very low (like 720x480).
-Now plug in your mini displayport to HDMI converter and plug your TV in to the converter.
-Smile as you see your Mac on your TV.
-Optional: You can test higher resolutions one by one to find the highest resolution your TV can handle.

Same boring problem.
Late 2009 15" MBP connected via Minidisplayport-hdmi adapter and hdmi cable, (both bought from Neet via Amazon) to 22" LG tv.
The mac sees the tv. It is added and removed in Display Prefs as I connect/disconnect the adapter, so there is some sort of communication going on. I have spent hours, including trying every possible combination of resolution and refresh rate in the Prefs pane - being careful to power the tv off and on again after every permutation. The tv constantly reports No Signal. I'm tempted to send it a clear signal with a very heavy object right now.
One thing I haven't seen mentioned here (or anywhere else) is the NTSC/PAL setting. Many of the available resolutions only allow 60Hz NTSC as a resolution. Anything else is greyed out. Here in UK our tv setting is PAL, not NTSC. Is this relevant when setting up a connection with the mac?

I sent an email to Neet cables, and I should say they have been great. Answered within a few minutes, saying they have sold thousands of these adapters and cables and not seen this problem before! They are mailing out a replacement adapter+cable today, and say that failures are v rare but not unheard of. However, because the tv is listed in the Display Prefs pane, I'm not hopeful that a new adapter or cable will help...we'll see. But this is definitely the kind of cust service that will take me back there again in future.
If only Apple would show they care too, and offer some wisdom here.

This worked on my mac air even though I am using cheep leads from china bought on eBay just press command and f1 and it connected to my samsung 40inch led tv ok just i had to alter the sound output in system preferences thanks for the tip I was expecting to have to by genuine apple cables

I'm having the same problem as a couple people here, had my 15' Macbook pro plugged into an Asus monitor through HDMI (mini-display port adapter ->HDMI cable). Worked fine until recently, however I noticed that shortly after the 10.6.5? update my macbook could no longer see my monitor, even though it was plugged in. I can use it with my TV fine, it just get a blue flicker, then nothing....

from what I have read, only mbp and mb from mid 2010 put out HDMI with audio.

My question for older models (is can you use the minidisplay -HDMI adaptor to hook up to TV for video, and then use RCA adaptor for audio?
Or, must you use minidisplay - DVI-D , then DVI-D - HDMI for video, and then RCA for audio?

Having the same problem in my new macbook pro 15" core i7, I uploaded a video in the youtube to show what happens: http://www.youtube.com/watch?v=Yf0RSb1tehM

Same problem
I had my MBP 13" 2010 connected to my 32" Samsung LCD until last week without any problems. Whenever i plugged in both TV and MBP recognized the the MiniDP to HDMI connection.

Since last week i cannot connect both these..whenever I do MBP screen goes blue for a few seconds as if it is detecting the HDMI connection and comesback normal...while on the TV it say 'NO SIGINAL'

I click gather display, noting gathers as the second display (TV) is not detected. Earlier when the same was connected, I was able to switch sounds from HDMI to Sound out put port via SYSTEM PREFERENCE->SOUND, but now there is no HDMI option there...so I it a good sign that Apple is not detecting the HDMI connection and it is not a 'display resolution' problem as most people have posted earlier.

I would also like to add that, between last week and now I had luck twice connecting these two, but it was sheer luck that MBP detected the TV via HDMI... There should be a way to get MAC to manually select the display output (similar to how the Audio output can be selected). I have tried replicating the same process when i got it work, but second time it didn't

Same thing here. Can not connect my macbook pro to lg tv or lg monitor. Both say just no signal. I ordered another adapter so we'll see if that's the problem.

I'm having the exact same problem as everyone else here which makes me think that there is no solution. I have a brand new MacBook, a mini display adaptor which, until today, has connected my computer to my Panasonic HDMI TV. *Please do let me know if the change in adaptor works as I suspect the problem might lie there too.*

I bought a new adapter from Kanex hope it works, it was the only one in amazon that haven't any bad reviews, now i'll have to wait 'till the end of january to receive it (I live in Brazil).
