I just installed Lion on my Mac mini and my TV no longer receives a signal over HDMI. I've tried a bunch of different cobinations of restarting the TV and computer without any luck. Without a display, I can't use Screen Sharing to try chaning any of the prefrences. Does anyone have a solution to this problem? Thanks.
For everyone who is having HDTV display and digital audio output problems take the advice of a few of the other posters here and go out and purchase Gefen HDMI Detective Plus. It retails for $129 but Amazon has it for sale for around $80. It will fix your Mac HDMI out video and audio problems period. Yeah it ***** you have to buy it but if you have the HDMI problems it was designed to fix you already have spent several thousand dollars on computer and home theater equipment so what is another $80 to keep everything working right.
By way of background, I have a late 2010 Quadcore I7 Imac, which also doubles as a HTPC for a 7.1 speaker set up in my loft with my Denon 4308CI amp and Panasonic HDTV (via a long 100 ft HDMI run). I use the Imac bluetooth keyboard and trackpad in the living room to control the Imac when viewing on my HDTV. The set up worked great with Snow Leopard until the 10.6.8 update killed my digital audio. I reverted to 10.6.7 to fix the issue until Lion 10.7.1 was released and I read on another Apple thread that the HDMI out issues had been solved. When I upgraded I lost both HDMI video and audio and I was hoping that 10.7.2 would solve the issues but it did not.
Anyhow, I was getting ready to go back to 10.6.7 again but read this whole thread for solutions and stumbled on the Gefen hardware solution. After doing some research it seems that many HTPCs have HDMI out problems with software updates and AV receivers and not just Apple. I bought the product, spoke to Gefen tech support before the set up as their instrucitons are a little unclear but after that I set up the product in no time and now everything is working perfectly once again. Best of all, I don't have to worry now about future software updates killing my HDMI out video and audio again.
BTW, if you use a AV receiver with your Imac just use one of the preset Gefen generic codes at set up as storing your HDTV's EDID in the Gefen may not allow you to push multi channel digital audio as well as video from your Imac.
A simular problem (only effecting audio) began on my 2010 mac mini for the first time today, after updating existing lion install to 10.7.2. https://discussions.apple.com/thread/3376125?answerId=16340146022#16340146022
To all those with audio problems, if you have anything plugged into
the headphone/line out jack of the Mini remove it. Some reports
on other threads say this is fixes the issue. SOme ahave also
just plugged something in, waited, then removed it and audio
again worked on HDMI.
For some reason, there is some very low level link between
the line out and HDMI audio which developers can't seem to
get working right. Probably the original engineer is gone
that developed the Mini and took that secret with him/her.
Just want to add my voice to this.
Mac Mini 2011, with Lion 10.7.1, connected HDMI to a Cambridge Audio Azur 650R, which in turn is connected to a Panasonic AE-4000 projector.
When I boot, I get the initial apple screen, and then it flicks and turns black. Obviously, it could not negotiate resolution with the projector.
If I connect directly to the projector, it worked for a few weeks, but now I got a black screen also.
Yes this issue is extremely intermittent and frustrating for me and always at the wrong times!
I have to turn the mac mini on and leave it for a good 5 - 10 minutes before anything will appear on the screen. This had sorted itself out for a couple of weeks but this problem is back.
I haven't seen the first apple boot logo since I have upgraded to lion. This means I can't boot into my windows partition on the first white start up screen. Lucky I use parralels with my bootcamp partition too.
When I do eventually get to use the mini I can't RESTART it. The mac will shutdown but there will be no start up. BAM no video.
I haven't yet seen a repsonse from apple on this forum (I'm not sure if they even do post to the forum as this is the only thread I've posted on). I'm going to trying ringing them this weekend for a response, but if not what then?
The patch didn't solve my problem.
Since my last post I have talked to Benq and they said that the monitor has not been certified for use with OS X. Not so sure I believe that. Sounds more like "don't know - don't care".
Hopefully this gets solved in a future update or release but in the meantime I have found a fix that works for me while letting me use LION.
I've gone through the entire update process twice to Lion losing my audio both attempts via HDMI but not my video before wiping and re-installing Leporard only to get everything back.
FOR ME what has worked for the past two months is upgrading to Lion 10.7. Everything works fine. If I further upgrade to 10.7.2 under "Software Update" I lose my audio. So here I've sat for the past past 2 months.
Just refrain from pushing that update button...LOL

i get red fuzzys all over my screen

can anyone tell me how to fix my display
Wow.
Just want to add my name to this long list. Same problem. My Panasonic HDTV no longer works via HDMI ever since Lion upgrade.
Very surprising that this hasn't been addressed yet with a fix from Apple...
I just upgraded my mac mini server 2011 to lion 10.7.3, and the problem is still the same or even worse, as the flickering now occurs in faster intervals, tried with HDMI to HDMI and MDisplayPort to HDMI.
For the record the MDisplayPort cable used to work perfectly on my mac mini 2010 and MBP 2010, and the HDMI cable is the one I used on my ATV2 which is still working ok, so its not a cable problem... 😟
I just dont understand how it is possible that if I connect it directly to my Pioneer Kuro TV it will output ok (no speakers on TV), but if I connect it directly to my Yamaha RX-V467 and the receiver to my Kuro it will just flicker nonstop... R.I.D.I.C.U.L.O.U.S
Apple please do something.
thanks.
I have this same issue. I travel between Germany and Spain with my Mac Mini (mid 2011 5.2, Lion 10.7.3). I have never had any probelms until today when I arrived in Spain and plugged my Mac Mini into my EIZO monitor using a HDMI to VGA adapter. Having left Germany this morning (where I plug directly into a full HD monitor via HDMI directly, and all was working perfectly), and I was somewhat taken aback when the EIZO monitor showed no signal being received from the Mac Mini. Tis same set up has always yilded perfect results from day 1.
I was further surprised that the Mac Mini correctly identified the monitor. I am having to screen share through my iPad and iTeleport (which is just not ideal), and so at this time my Mac Mini is useless, dead and basically as good as a $1,700 door stop.
I have tried resetting the PRAM, and many other issues discseed in this thread, but to no avail. Further, I tried the 1.4 firmware update, but the Mini tells me that this software is not compatible with my system.
I am in Spain for the next week and I need ot get back up and running, without using my iPad as a monitor. Any suggestions?
Thanks ahead of time,

I have ordered new cables from supra (their best series) and will probably receive them on wendnesday, i will return with the results then but i doesn't think it will solve the problem.
Why can't apple fix the bug in lion so the handshake works? Is there a way to get around the HDCP-problem?
Copying thsi from antoher thread but this is what solved my issue AMcbook Pro 13" with lion
OK, I waited thirty minutes and then had to solve it myself.
Here is what worked.
Plugged in Power, don’t ask but this seemed to help me get at least to a display but still had the flickering.
Go to the system preferences, select Displays
Check the box “Show Displays in Menu Bar”
From there you should see your displays listed. Pick a resolution setting that stops the flickering.
You should now have a stable screen.
I did not select mirroring as this caused my display to not be as sharp. Instead you have to drag the content you want over to the monitor over. For video conference this was perfect as we can have the video app running on the LCD screen and then view other content on the MacBook on the conference table.
Hope this helps some, at least it solve my immediate problem. Just to be safe, keeping the Dell out of sight in a cabinet.
Cheers!
I have now tried my supra -Met 1.4 cabels without any result, still no signal and probably a waste of money. I am still waiting for Applesupport to get back to me about the problem, only been wating for a week, really hope they will come up with a solution...
Is it any one that has a mac mini -> receiver that works fine in 1080p? Would be nice if you share which receiver(brand and model), cables and tv is used and how it is connected(maybe matris, split or a ps3 in the receiver also)!

This IS embarassing. My hunch is that it is a timing issue, whereby either the mac mini was not ready when the handshake was sent from the projector and missed it, or the mac mini does not wait long enough for the handshake signal.
The people who have success, by changing cables, or have it sometimes work and sometimes not, are simply seeing situations where the timing 'worked' on occasion.
