Mini display port to HDMI problem

im tired of this trouble.

Bought numerous adapters to try make it work with an unbranded LCD, and cant make it happen.

I'm having the same issue that everyone has here. Blue screen for 2 seconds and no signal then.

My other samsung lcds work ok as i would like on my bedroom's "Daytek 32".

I've tried to contact apple and tell them that this issue havnt been solved since a long while, but figured out that my warranty is over (Macbook Air 11 bought on March).

If anyone is able to report this post and open a support issue with apple, that would help to solve this problems.

Thank you.

Same issue here! Just bought the new mac mini and receive no video output with my Philips TV... Just got off the phone with Customer Support and they told me that at the moment Lion does not work with Philips TVs and that they have escalated to the engineers looking for a solution. This will of course, be fixed in the next software update but no idea of when will it happen!

So, at the moment, Philips and Lion customers are in the dark... :-/

I guess the same for your Daytek 32...

I've the same problem since I updated to Lion. I worked nicely with my 13" Macbokk Air and SL 10.6.8. I ve a Deal extrem mini dp to hdmi cord and a SONY Bravia TV. I've tried the PRAM reset... No effect. I'm really not happy with Apple/Lion. So what's the problem ?

I am using the Kenex mini DVI to HDMI cable (bought from apple site) from a MBP 17" 2010 to a Epson 8350 projector. Kenex informs me this cable works with my MBP and Epson 8350. Worked fine until the apple system update. Now just message on projector 'No signal' and sometimes for variation 'Not supported'. It seems apple are protecting copyright above functionality. Does anyone from apple ever read these postings? If so this should be fixed ASAP. This is not good enough for consumers. When the mini dvi is connected the sound on the USB port is blocked to my DAC too. Unplug the Mini DVI and itunes works. They really have gone over the top with that copyright protection with HDMI. I am seriously tempted to get a third party solution that removes the hdmi encryption.

HDMI is a badly designed interface developed for the purpose of controlling content not a superior signal. Since control could not be done with analog connections, HDMI was a new digital alternative to allow whoever wanted to control the content with HDCP.

Problems with HDMI are not usually with the cable but is in the HDCP copy-protection protocol. There was a technical paper from the HDCP group pointing out that some developers of switches are making incorrect assumptions about the way to handle HDMI/HDCP standards.

HDMI is being pushed because of the copy protection. High-bandwidth Digital Content Protection (HDCP) is a form of Digital Rights Management (DRM) developed by Intel Corporation to control digital audio and video content as it travels across Digital Visual Interface (DVI) or High-Definition Multimedia Interface (HDMI) connections. The specification is proprietary, and creating an implementation of HDCP requires a license.

HDCP is licensed by Digital Content Protection, a subsidiary of Intel. In addition to paying fees, licensees agree to limit the capabilities of their products. For example, high-definition digital video content must be restricted to DVD quality on non-HDCP compliant video outputs when requested by the source. DVD-Audio content is restricted to DAT quality on non-HDCP digital audio outputs (analog audio outputs have no quality limits). Licensees cannot allow their devices to make copies of content, and must design their products in ways that effectively frustrate attempts to defeat the content protection requirements

Yeah, HDMI use HDCP protection, whatever. Stoping users that bought computers at thousand of dollars and wanting to duplicate a screen already being shown in a smaller ppi is not about content protection, it's a d*mn user jail! Why would an apple branded cable have more rights than others, seems to be all about money out there. What about if my macbook screen die and I don't have that uncomment warenty and no 1000$ waiting around to be spent for a screen repair.

That's right, with your new computer, you don't have the right to use a screen or a tv, even if you paid it 2500$.

Because of this $?%&*! update, I'll have to use a pc for my slideshows and courses!

frederic1943, I don't know if you're an apple guy or only a good guy informing us about that HDCP thing, I can't see your face while reading this and english is not my primary langage, but it's nothing against you:

It's all about Apple and a computer feature being featured and not being working as it is said to be.

How depressing.

Can't wait for this technology to become history. I can see people talking to future generations about how they used MDP to HDMI and people asking:-

"Really! But that technology never worked properly and they knew it. How many years did you try to get it to work for?"

It reminds me of ADB to USB adaptors. What a joke they were. The apple techs at university, unable to get them to work eventually give them away free as a challenge to see if anyone else could get them to behave consistently. No one ever did.

I have about $3000 invested in using my projector as a desktop monitor ( I don't care if it is not encrypted) and all apple and their intel buddies cares about it protecting data and looking after share holders. Anyone looking at this posting is paying for the 'joy' of being a beta tester for mini DVI to HDMI, an interface that should never have gone to market.

There is no hope for you, apple has forgotten you. Apple never reads these posts. No money in it, one could say.

I cling to the hope that history will prove me wrong.

It already worked in the past, why wouldn't it be working today :/

And what if we all call Apple and ask them to fix this, maybe no one is being paid to read this, but some are being paid in the custommer services.

I know that starting a petition or getting Apple in justice would be too much effort for that and Apple probably have the right to let it that way, but we can still give a try at their number. I wish history will prove me wrong too simonfromkingston.

Okay Great idea! Let's start a petition.

To Apple Corp

On Behalf of all Apple customers that use any Mini DVI to HDMI interface will you please work very fast to solve any hardware or software issues relating to this interface.

Not just Apple but every TV maker. They have to have their HDCP handshakes match exactly. If you don't update your TVs firmware regularly to match the latest HDCP you're going to have problems. I learned all about this a couple of years ago when I was trying to get my DVR to work with my HD TVs HDMI.

Yes, I have been unable to get my MonoPrice miniDisplayPort to HDMI cables to work with any of my Macs.

But, what does work fine is miniDisplayPort to DVI adapter with a DVI to HDMI cable. I use these with several Mac laptops and desktops to connect to a variety of projectors, monitors and TVs. I've rarely had any problems. The cheap adapters and cables from MonoPrice seem to work fine, as do the more expensive Apple brand adapters.

The reason why I want the miniDisplayPort to HDMI cable to work is that it should pass audio along with video through the HDMI connection. That would be nice, and I would have less cable clutter. DVI adapters don't to audio.

I am considering purchasing one of the miniDisplayPort to HDMI cables listed on the Apple Store website... I haven't tried any of those brands yet.

Hi,

I've been using this one for three months now without any problems:

http://www.dealextreme.com/p/mini-displayport-male-to-hdmi-female-adapter-1080p- 27549

I think it's worth to try before buying any expensive adapters. Audio is included to this adapter.

This is the one which DOESN'T anymore work, so don't buy this one:

You're running last lion update with apple latest hardware and mini-displayport-male-to-hdmi-female-adapter-1080p- 27549 is working fine right?

If it is really working well, I'll probably pay 10$ instead of crying at apple...

i have a 32 inch sony bravia that i am trying to connect my macbook to. i plugged in the mini DVI to hdmi cable and the picture works perfectly. however im not getting any sound neither from the hdmi itself nor when i connect a audio out connection with the red and white connectors directly to the ports on the side of the tv. i also tried using the other ports on the back of the TV with on success. need some help quick! thank you for all the help.
