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,

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.

Hdmi adapter problem

I own Phillips 32pfl9604h TV. Recently I bought HDMI adapter. When I set up the iPad with HDMI to TV , TV is recognizing the iPad but the format is constantly switching between 2 different formats. I tried to connect it to a different model of TV and it does work normally. I've tried to change the format but I can't stop the changing of formats.
Is there any solutions for this?
Thank you in advance.

Mini Displayport to HDMI Adapter Problems!!!

Okay so I have a MacBook Pro running OS X version 10.5.8.
2.4 GHz intel core 2 duo
And I recently got a Phillips flat screen tv with HDMI hook ups.
So naturally I wanted to connect my Mac.
So I went to Best Buy and purchased the Rocketfish mini displayport to HDMI adapter.
However upon connecting everything to my computer, nothing happened.
No picture came up on my tv, no sound, no change at all.
My computer doesn't even say there's a device connected.
Is there some sort of steps to setting it up?
I was under the impression I'd just have to plug it in and it would work.
Do I need to get another adapter?
Please help!
Thank you!

Took the MBP to the apple store. The display port works fine.
Embarassingly the tech pointed out the USB plug on the adaptor which I hadn't connected thinking it would be for another peripheral. Hey presto it worked!
Red faced thanks!

DVI to HDMI Adapter Problem?

Hello Forum - I'd like to describe an issue and see if there are others with same or is it just me:
I have a early 2011 Macbook Pro 15" with 16GB ram, 1TB hard etc.
I have 2 profiles on the machine - one is dedicated to work running Fusion VM of various windows servers and workstations and the other is dedicated to home/personal use.
I have 2 mini dvi adapters, one for VGA that stays in the office and one that is DVI that stays at home
Recently (last week) while at home I went into system preferences to make a change to my desktop background picture on the extended desktop monitor and preferences locked up (I had to force quit) Tried this three times with same results - I then unplugged the mini adapter using only the laptop screen and all was OK.
Went to work the next day and under the work profile tried the same thing, nothing went wrong so I figured it was a fluke error, no big deal,
Few days later at home I tried again and the same issue - lockup.
read a few internet forums over the holiday weekend and tried what users suggested related to iPhoto library yada, yada and nothing worked. So today in the office I logged into my personal profile and everything works fine with preferences - so there was my yurika moment - the adapter!
So - the long awaited question is - is this a common issue with the mini adapters failing? Called apple tech support and they say no asked me to try a few more things mainly a repeat of what I have done so far to date but to bring the adapter I have at work home and try it there (they forget one is VGA and one is DVI) but I will humor them and try it and see - or should I just go to apple store and but another adapter?
Thoughts would be appreciated

I have seen the exact same problem. I thought it was an issue with my computer, but after reading this it seems like a general problem. I am connecting to a monitor using HDMI to HDMI. I also got a kernal panic on the mac this morning and com.apple.driver.IOGraphicsFamilty was in the report

HT4241 HDMI sound problems?

I have a Macbook Pro and am trying to connect it to my tv. The video is there, but no sound is coming up. I go to the system preferences, then sound, and there is no option to choose my TV as the audio output. Any help? Thanks!

Did you select the TV as the sound output device (System Preferences > Sound > Output > {your TV})?
Sorry, can't help with YouTube versus VLCplayer.

DVI-HDMI Adapter for hooking up a HDTV...Few problems...

I have a spare 32" Sharp HDTV with HDMI, so I placed this next to my Mac Pro and used a DVI-HDMI adapter. Here are the problems:
With my standard GeForce 7300 GT you cannot use both connectors, as they are too close together - so I could not even test to see whether both DVI outputs can work at the same time. So I have to disconnect my 23" cinema display. Now, the Macpro recognizes the TV - in the display preferences - but the resolutions are not good - the only one that works is 1280x720. Other resolutions listed, ie, 1344x756 and higher are listed as interlaced and all cause flicker. This means I do not see the OSX top menus.
I wish to be able to show clients samples of edited movie clips on a HDTV both in FCP and standalone QT. I doubt that appleTV is the answer, as this only works in iTunes - plus, my Mac is next to my TV anyway.
Any thoughts on making this work better? I am trying to not have to buy a new video card. Maybe the Black Magic Intensity card for HDMI output is the answer?

I can live with the lower resolution - the TV is actually 1366 x 768, but the most annoying is not being able to use both DVD connectors on the card at the same time - they are too close together, how stupid is that?
Ideally, I would like to see both the cinema display and the HDTV running at the same time - or least not having to manually switch over the adapter at the rear.
I see no way around this, unless I change video cards but for $250 I can get the Black Magic HDMI card which outputs DV via HDMI to HDMI.

HT4241 Mini DVI to HDMI adapter. Not gettint desktop to show on TV

I have the Apple mini to HDMI adapter. When I plug my late 2008 Mac 13" up to my TV, it doesn't show my desktop. It acts like a 2nd screen. I can drag stuff from my Mac desktop over to the TV. Is there a setting I am not finding I need to change?

You have the display set in Extended Desktop mode with the MacBook as the main screen. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen.
In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen.
The TV will now have the Dock and Menu Bar and windows will open on it. But you can move the cursor to the MacBook screen and move windows from the TV over to the MacBook screen.
You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box. That will give you the same screen at the same resolution on both the MacBook and the external monitor.

HT4241 Mini dv to HDMI adapter

Over the last several months I have enjoyed showing my computers screen up on my nice HD television via a minidv to hdmi adapter I got off amazon. The last few weeks, sometimes when I'd plug it in it would only show the default lion destop image (which is not my current wallpaper). Anything I would open on the computer would not show on the TV, just the picture of a galaxy. In the begining I would just restart my computer and it would work again. Now it's not going away. I have restarted my computer several times and reset the pram because I dont know any other troubleshooting steps other than that. Is there like a hotkey to show whats actually on my computer and thats just like a standby mode or something? Any help would be much appreciatted, Todd
p.s. also the time when it stopped working completly is after I got my display and battery replace from the applestore because they were having issues, not sure if that would really have anything to do with it though.

nevermind, I didnt have mirror displays checked in system preferences under displays. issue resolved.

HT4241 Mini DisplayPort to HDMI adapter, no sound

I've bought a Mini DisplayPort to HDMI adapter when connected to my SONY BRAVIA, it only showed video, the audio sound still came from my laptop not from my tv? shouldn't HDMI support both audio and video

I believe the 2010 and newer ones support audio through the HDMI cable. Earlier MBPs will require one to tap the audio output port and run separate wires to the RCA audio input connectors on the TV. Also you might check your Sony user manual to make certain that you have it set up correctly as well as the MBP.
Ciao.

My Apple Mini Display Port/HDMI adapter is not working after upgrading to Maverick?

I am using my 13" Macbook Pro Purchased July 2013 on my 42" Samsung TV. I route through a HDMI adapter (purchased from Apple) to do my presentations. As a note my setup has been working great for the last year. Immediately following the upgrade to Maverick my Samsung displays "No Signal" and changes state "Check Signal Cable" when the cable is disconnected. Obviously there is some type of signal but it is not recognized. I tried working with Apple support and they said that the adapter I was using must not be an Apple product. I investigated fully thinking I may have possibly bought the wrong item, after much research I have exactly the same thing sold on the Apple store online and I even went to 3 Apple stores locally to see if there was possibly another adapter that I should have purchased, but it was exactly the same thing I purchased originally. Help me fix the problem or please provide details on how to go back in operating systems to prior to Maverick (and not lose any of my data), this upgrade was a huge mistake way to many problems and not the quality that I am used to from Apple.

Had a similar problem, but the answer is not a good one.
You are going to have to wait until Apple fix this as some 3rd party monitors are not supported by this update.
So you can:
Go back to 10.6.7
Wait for Lion
or
Use Onxy to clear up your computer and it may link to it again.
I deleted some preference files, which when they rebuilt themselves after a restart did the trick.
It worked for me, let me know how you get on?

Lightning HDMI Adapter not working with iOS 6.1.2

I have an iPhone 5 which was updated from 6.0.2 to 6.1.2 recently and the Lightning HDMI adapter stopped working altogether for video mirroring; was wondering if anyone has the same situation/any solution for this?
I also have an iPad retina generation which is at 6.1.2, and the Lightning HDMI adapter is not working for it as well.
I've tried replacing HDMI cables, rebooting the iPhone with the cable plugged in, and plugging out/in several times with the charger in/out. The adapter works, cause when I plug it in; I see the top bar flash for a bit... but no dice on the video mirroring to my TV.

I also have this problem and am very unhappy with the way Apple is handling it. Called today to enquire on when the fix will be available and was told it is a software issue that could be fixed if we paid $35.00 to talked through process on the phone. Highly disappointed with Apple, why should it cost me money for them to fix there own issue. Since they are aware of the issue the least they can do it posted the information for the fix online @ no charge.
If I wanted crap service I could have gotten a phone from anyone. Reconsidering purchasing a 5 on next upgrade.

I have a late 2008 white macbook. I have a mini dvi to hdmi adapter, and a hdmi cord. My cannot get my MB to detect an external monitor. Nothing happens when plugged in. Also, my display settings does not have an option for mirroring or arrangment tab

Yeah, I'm having the same exact problem - It seems that the thunderbolt minidisplay port is only able to output the analog VGA signal, not the digital signal to support DVI and HDMI. This is a bug that came up after installing 10.7.1. I bought my macbook air with 10.7 on it, upgraded it to 10.7.1 as soon as I got it, so I have never been able to use hdmi or dvi with my macbook air. This is an extremely frustrating problem for me, I used HDMI on a daily basis with my PC. I have spent many hours at the genius bar running diagnostic tests so Apple can get as much information as possible to create a fix for this problem. I have been emailing tech support for 3 or so weeks now, they keep saying that they are working on a fix and it should be out soon, but 10.7.2 has come and gone and I still have no HDMI functionality with my MacBook Air!
