Mini-DVI to HDMI output to Philips HDTV not working with Yosemite

I've recently upgraded to the Yosemite OS, and was surprised to find out that the output to my Philips HDTV no longer works. I have a Mini-DVI to HDMI converter, which I then plug into the TV. Before the upgrade everything worked fine (I think I was running 10.7), however now it just says "Video format not supported". I've tried every video format too...nothing seems to work anymore. With my friend's Windows laptop direct output via the HDMI port to the TV works fine, so it's not a hardware issue.
The Philips TV is an 8000 Series HDTV and I've already checked for the latest updates, but it says the software is up-to-date.
Anyone have a similar problem or know of any solutions???
Thanks in advance!

I would contact Phillips and see if they have a solution.
Ciao.

Mini-DVI to HDMI Problem

Hi, I bought a Mini-DVI to HDMI adapter like this one: http://www.hdtvsupply.com/mini-dvi-to-hdmi.html to be able to hook up my macbook (2007 white version) to my HDTV. However, since HDMI is traditionally for both video AND audio, the HDMI channel on the TV can only output audio coming in through the HDMI cable. There is no sound, because I am only feeding video through that channel.
To solve the issue, I purchased the following 6ft 3.5mm Stereo Plug/2 RCA Plug Cable: http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10218&cs_id=1021804 &p_id=665&seq=1&format=1#largeimage. The problem is, that I am only able to play sound from my laptop on my HDTV on one channel, and video from the Mini-DVI to HDMI adapter on another, but not both audio and video at the same time. What is the SIMPLEST way to fix this? I wouldn't want to purchase any additional cables if possible
Many thanks for your help in advance!!!

Thanks for that. I have a Y adapter (3.5mm stereo headphone jack to RCA sound just like you said). Under input options on my TV, I can select either HDMI1 input (which gives me video only) or AV1/S input (which gives me audio only) - not both at once...Could you explain how I can get stereo audio on my TV?

My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. It was working fine now I cant get it to output to the Tv. Any ideas?

My Macbook pro no longer outputs to my vizio led tv. It was working fine now I cant get any picture. It just says no signal. It is not the hdmi or the adapter because it works fine with my other tv. Any ideas on how to resolve this would be greatly appreciated. Please be as specific as possible. Thanks. BTW--I am using the mini dvi to hdmi adapter in case that was unclear.

Since you say that the same connectors work on your other TV is suggests that the fault is not in the connectors but your Vizio TV. I would check the settings on the Vizio TV. Verify that is is set to receive HDMI input. Perhaps you or some one else has inadvertently changed them. Pressing the wrong buttons on a remote control device can do that. (I am assuming no changes were made in SYSTEM PREFERENCES>DISPLAYS)
Ciao.

Can a MacBook (Early 2008) Support both sound and video to 1080p HDTV by Mini-DVI to HDMI cable?

Can a MacBook (Early 2008) Support both sound and video to 1080p HDTV by Mini-DVI to HDMI cable?

The mini dvi on the MacBook will only support video, in order to get audio you'll need to a cable from the sound out port to the sound in port on the TV.

Can I use a mini-DVI to HDMI adapter to use my HDTV as a monitor?

I've been looking into this and haven't found a direct and complete answer yet. I read this article that states its possible when using mini-DVI to VGA/DVI adapters, but didn't mention mini-DVI to HDMI adapters.
http://support.apple.com/kb/HT3413
Apple also doesn't offer mini-DVI to HDMI adapters, so where would be a good place to look for one and what do you think I should pay for it?

If you have a unibody MBP, you need a mini-Displayport adapter, not a mini-DVI adapter.
If you don't mind running a separate audio cable in addition to the HDMI cable from your MBP to your TV set, buy this adapter:
http://www.monoprice.com/products/search.asp?keyword=5311&x=0&y=0
If you want to combine video and audio into a single HDMI cable, buy one of these two adapters:
http://kanexlive.com/products/item.aspx?id=3323 (for two-channel stereo audio)
http://kanexlive.com/products/item.aspx?id=3495 (for 5.1-channel digital surround audio from sources that include it)

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.

"Mini DVI to HDMI" or "Mini DVI to VGA" to go to Samsung LN32B460 HDTV?

I recently purchased a "DOA"/defective "Mini DVI to HDMI" converter off of ebay, and the company is making me spend the $10 to return it to China - which I'm not doing (I only paid $10 for it in the first place).
I am wondering if I should buy another one, from a more reliable seller of course, or if I should buy the "Mini DVI to VGA" instead?
I don't play games, so it would be mainly for playing movies and browsing the web. My display is a 32" Samsung 720p (Model LN32B460). It is has a native resolution of 1360x768, 60Hz refresh.
Will I see a quality difference for the basic stuff that I am doing that I should get the "Mini DVI to HDMI" or will the "Mini DVI to VGA" be enough?
Thanks!

Difficut to say why it won't work, but my guess is your vintage iMac (about 2007) was never designed to output via HDMI. Your adapter appears correct (thanks for the Amazon link) so if you want to persist, you can contact Amazon and request and exchange to check it. But I suspect you will need to use VGA or if your TV has it DVI which would mean using a mini-DVI to DVI adapter.
One last thought is you could invest in an Apple TV and then do it wirlessly. That would work too but requires and AppleTV to accomplish it, of course you can use the AppleTV for streaming other data too including video, photos, music etc....

White MacBook 2.16, mini-DVI to HDMI, no audio

I have connected a 32" Sony HDTV to my MacBook via a short adapter cable, mini-DVI to HDMI, and then a 3m HDMI cable. The video is excellent and although there is sound output from Macbook, there is none from the TV. Any suggestions how to get audio through the TV?

Just to add in case someone else views this thread via a Google search.
None of the Apple video adapters (for the current and previous portable line up) support audio through them, even the newer MacBooks and MacBook Pros with MiniDisplay Port. There are 3rd party adapters that have all the necessary cabling for audio and video but those are not available through Apple.

Mini dvi to HDMI no longer working to t.v.

Hello. For months I was able to use the mini dvi to HDMI to use my Samsung HD t.v. as a monitor from my Macbook Pro. Suddenly one day when I started it up, the t.v. said "No Signal" and then the Macbook Pro goes to sleep. If I take out the mini dvi it will wake up again, but the moment I put it back the t.v. goes back for a second the way it usually would when it first recognizes the mac, then the mac goes to sleep again. If I look at the built in display, I can see that it isn't even detecting the Samsung is hooked up any more. Could the video card have already gone bad? It isn't even six months old.

I'm having similar problems. I have a Toshiba Regza 1080p HDTV and frustrated that I cannot get my audio and video to work selecting one INPUT source on the TV. I used to stream Netflix with the minidiv and a separate mini stereo cable and it worked! until I moved and voila it stopped working. Grrrrr. I switched to a mini stereo y cable when a technician told me perhaps my audio cable was bad. Tried every combination of display setting on my Macbook Pro (OSX 10.5.8) and I'm stumped. Little to no sound setting on my MBP as some forums advise that I select an HDMI output. BL: My MBP sends audio out (thru HD Colorstream 1 audio input) and video using minidvi-HDMI to Toshiba's HMDI 1 (tried HDMI 2; etc.) Nothing works. Since only one input may be selected thru the HDTV at any given time I cannot figure out what I need to do the get the audio from Colorstream HD1 and HDMI video to synchronize. I just read about the Mini DisplayPort to HDMI Adapter Pro w/Optical Audio cable and wondering if that will push my audio from MBP and video to the Toshiba HDMI port thus allowing me to select one input source on my Toshiba 1080p HDTV and perhaps being a solution? Before I go out and buy this I need some help from you smart folks. Thank you!

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.

VGA vs Mini-DVI to HDMI adapter

I'm about to buy an external monitor to use with my MacBook Pro late 2008. I do understand HDMI (digital) looks much better than VGA (analog), so I'm thinking about buying a Mini-DVI to HDMI adapter. My questions are:
Does the Mini-DVI to HDMI adapter decrease video quality? Is it noticeable?
Is it worth buying the adapter? If so, are there any known issues with third-party adapters?
Thanks in advance for your time!
João

If your macbook has mini-DVI then HDMI or no HDMI you will not get any audio passed through the HDMI connection because DVI does not pass audio. You would need to pass the audio separately via analog stereo line out.
But what difference does it make anyhow? You intend to use this as a monitor as opposed to hooking it up to a HDTV.
So long as you use a digitial interface HDMI, DVI, mini-displayport, etc. you are not going to loose any quality. It's digital. It either works or it doesn't. VGA, being analog, will of course be less quality.
I don't even know why you care about converting to HDMI when you could just convert mini-DVI to standard DVI and use a monitor that accepts standard DVI. They're plenty of those around.
Another consideration with a DVI interface is that if the monitor has a resolution greater than 1920 x 1200 you need a dual link DVI adapter as opposed to a single link DVI adapter.

Mini dvi to hdmi adapter

I have ordered a mini dvi to female hdmi adapter for my MacBook...and hdmi cable to run to my Pansonic HDTV; so I can watch movies I rent from iTunes.
Do I need an additional cable for sound? If so, please inform what I need? I do have HDMI Audio input wht/red connections on back of TV. I just don't know what to buy if I need an additional long cable for audio?
Can I set this up to have video and audio connection with one cable?

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!

Mini dvi to hdmi

I just purchased an adapter to connect my imac (intel core duo) to my lcd hdtv. I am using a mini dvi to hdmi adapter. When i plugged it into my imac and macbook it recognized my tv right away as another display. Is this the best way to get video to my tv? Is there another way to achieve better video quality?

That is the best way.
Is there another way to achieve better video quality?
Are you asking because the quality is not acceptable? It should be digital all the way, you can't get any better. If the HDTV is capable of 1080p, make sure the resolution setting in System Preferences Displays pane is set to 1920x1080. Also, make sure you are NOT using the Mirror setting; you want the two screen in extended desktop mode, using the optimum resolution for each screen.
