Mountain lion vs HDMI

Problem with HDMI. After installing mountain lion, I have noticed that, if I plug in a HDMI cable (to watch a movie from the mac to a bigger screen), the mac screen becomes blue in a non reversible way, which means that, even if I unplug the cable, the blue screen remains and I have to force shut down the computer to make it work. Can anyone tell me how to solve it? thanks

How to connect MacBook Pro 17" Mountain Lion with HDMI port on TV, Panasonic TC-P55ST50

Any experience with cables for connecting MacBook Pro 17" Mountain Lion with HDMI port on TV, Panasonic TC-P55ST50 (or similar)?

It depend upon the model (age) of you MBP. If you have a Thunderbolt or minidisplay port, then you will need a minidisplay/HDMI adapter.

Or you can get an all in one:

If you have an older mac with a DVI port, you will need something like this:

Note that audio is supported via HDMI for MBPs 2010 and later. Earlier ones require tapping the audio output port.

How can I connect my Early 2011" Macbook Pro 13" inch, with a generic Mini Display Port to HDMI connector, to a LG 32LD340 LCD TV, using Mountain Lion 10.8.2?

I have an Early 2011" macbook pro 13 inch (core i5 2.3ghz 4gb ram 320hdd) with Mountain Lion 10.8.2, and I want to connect it via Mini DP to HDMI connector, and a HDMI cable to a LCD TV LG 32LD340. When I had Lion OS, I had no problems at all.

If you have an external drive equal to or larger than your internal HD, clone your internal to it with either Carbon Copy Cloner or Super Duper. Test the clone to make sure it's bootable. Then upgrade either one. Try it out first.

I have a late 2011 model MacBook Pro running Mountain Lion. I love the AirPlay mirroring feature with Apple TV...BUT, how do I mirror with TVs that don't have Apple TV? I used to run a cable from my mini display port to the HDMI input of a TV.

I used to run a cable from my mini display port to the HDMI input of a TV. This feature seems to be lost in the Mountain Lion upgrade. Did Apple feel that once Mountain Lion came out that EVERYONE would have Apple TV? There are no settings in System Preferences/Display like there used to be...only for AirPlay Mirroring.

Running a cable to the HDMI port is still supported. (and still works on mine).
If the Arrangement tab in System Preferences > Displays isn't present then it doesn't recognize the physical connection. Double check all cables. If that doesn't work try a PRAM reset:

HDMI, Mini Display Port and Mountain Lion

Hello,
After reading about numerous issues concerning the Mini Display Port and Mountain Lion, I'm trying to discuss it here with you all to see if there is any solution.
I have a MacBook Pro (2009), and used it with my TV (HDMI cable + Mini display port adaptor) with Plex media center back when it was on OS X Lion. It was very convenient because as a portable computer, it could easily be set near the TV and allow the use of a remote to sit in the couch and stream media from the Time Capsule… without the help of any expansive box. Perfect setup I've had for over a year.
The thing is, since I've upgraded to Mountain Lion, when I try to connect the MacBook Pro to the TV, the screen turns blue as if it was calculating the resolution of the monitor so… ok. Until it comes back, and nothing changed either on the MacBook Pro screen or on the TV.
Harware side, I've tried with the computer open, closed, I've checked every port and connection on both computer, TV and adaptor.
Software side, what I find really annoying in Mountain Lion is that they completely ditched every monitor setting as long as nothing is connected — and even if the Mini DP is connected… the Mac thinks it's not. I even tried to reset the PRAM. This is a nightmare.
I've tried to do the same with my iMac (mid 2011), and it all worked properly. What I can't explain is why it works on my iMac and not on the MBP… as they have the same configuration !
I don't know if Apple is outcasting old devices so people buy new Apple stuff or if they ditched the HDMI out on certain (old) devices on purpose so users replace it by the new airplay mirroring feature and buy the Apple TV. I won't, because let's say it's a total crap compared to other media center solutions. And I'm bored of Apple.
Please, HELP NEEDED ! Has anyone had the same issue ? I bet you have ! Now how can we solve that ?
Thank you for your time.

EDIT : stopped working on iMac too… then update 10.8.2 fixed the issue. Now it works. Thanks Apple for temporarily removing some features ! It's just so ANNOYING.
Hope you gonna stay with the few we have left on Mac and stop removing things randomly. Not event talking about the pro environment (designers, developpers, etc.) that is almost gone. 2 years and our macs will be tablets. Careful with the old clients… it's been almost 10 years I'm on a Mac and I've never been so unhappy.

Hi i upgrade from lion to mountain lion to day on my mini mac,Since the upgrade i am getting no sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever

Hi i upgraded from lion to mountain lion to day on my mini mac,Since the upgrade i am no longer getting sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever.Any one any ideas?
I use a samsung TV for my monitor via HDMI.Tried all the system Audi setting nothing .Head phone and internal speakers are fine.

Similar issue; Audio was working fine on Lion, now not on Mountain Lion. Have a Macbook Pro early 2011 with AMD Radeon HD 6750M, connected by thunderbolt through a Lacie LBD to a mini-displayport to HDMI adapter (n.b. same problem when not going through the LBD) to a Pioneer VSX 521 AV receiver. For me when I go into audio Midi settings all the volume sliders for the displayport device are greyed out and at zero. But when I click 'configure speakers', it's able to send out the test signals to each speaker. Part of the problem could be that I'm not getting the option to put out 6channel sound, only 2 or 8 channel. Since my system is Dolby 5.1, and I only have 6 speakers, I would have expected the 6ch option to be available. But I imagine there's more to it than that. Elsewhere someone has suggested playing with Remote Interactive over HD on an Onkyo device; I'll see if there's something similar on the Pioneer that can be changed. Any other suggestions welcome.

I upgraded to mountain lion, now my mini dvi to hdmi doesn't work

I installed mountain lion and now my mini dvi to hdmi doesn't work. I did a disk permission repair, but that didn't help. Any suggestions?

My internet card will only work on 32bit,and it sounds like mountain lion only works on 64bit so that must be my problem. I think I will have to upgrade my internet or go back to lion.

After upgrading to mountain lion I cannot use my HD TV as a display through my thunder port and HDMI cable ???

after upgrading to mountain lion I cannot use my HD TV as a display anymore using thunderport and HDMI , which worked before , does this mean I have to buy apple tv to mirror onto my HD TV

can it be something related to wi-fi? I have read other posts talking about loss of connection using wifi. I'm connecting my G5 through an airport express which is expanding my wifi generated from my Apple Time Capsule. It is quite difficult for me to relocate the server close to the Time Capsule and vice versa but if it works, at least that would be something. It was working with Lion about 3 months ago - showing up in Finder, etc.

HDMI Video corruption under Mountain Lion

I have a mid 2011 15 inch Macbook pro. Upgraded to Mountain Lion. I use an HDMI TV connection as an external monitor with the laptop closed. I switch to another work PC on the TV using the source selection. This causes the Mac to Sleep because no external monitor is detected. When returning to the mac and waking it up via a blue tooth track pad, the video is corrupted. It's just scrambled.
Unplugging the monitor and plugging it back in, doesn't help.
Unplugging the monitor, opening the mac, then plugging in the cable fixes it. I use a mini display port to HDMI connector.
This worked fine with no corruption under Lion - but it is easily reproducable with corruption under Mountain Lion.
Any advice?

Opening and closing the lid corrects the problem by causing the external monitor to refresh.
It doesn't have to be disconnected and reconnected.
The problem still occurs after the 10.8.1 update.

VGA and HDMI DisplayPort Adapter stoped work on Mountain Lion

Hardware: MBP early 2011
With Mountain Lion 10.8.0
My HDMI adapter stoped working.
With Mountain Lion 10.8.1
Both HDMI and VGA adapter stoped working

I found a solution to this problem!
Download the driver that's mentioned at the link below and follow username "asabaraba's" instructions. It involves ditching the RaLink wireless utility and using a compatible DLink one.

You can't install OS X on a PC. Buy a Mac and you can install Windows on it in a second partition.

USB 3.0 to HDMI External Video Card USB32HDE Mountain lion?

Hey!
I bought one of those USB 3.0 to HDMI External Video Card Multi Monitor Adapter (USB32HDE) and read it should work on MACBOOK Air before purchase. However at the same time i installed mountain lion and it seems nothing is happening?
Do anyone have an idea if its due the Mountain lion or it just dont work on macbooks at all?
thanks guys!

TL;DR, J5Create has a similar device to the StarTech USB32HDE called the JUA 350. So similar in fact, they use the same drivers, and J5Create distributes the OS X drivers.
Hi, I found this post through Google and thought I'd provide my solution for anyone else who runs into this. I also bought a StarTech USB32HDE for my Air, which was not my smartest purchase ever since I can now clearly see that StarTech only officially supports Windows, supplying a zip file containing drivers from a company called Trigger. Thankfully, while I was looking at alternatives in preparation to return the USB32HDE, I found the J5Create JUA 350, which looks almost identical. On a whim I decided to grab the JUA 350 drivers and give them a shot. When I opened the dmg, lo and behold, the drivers provided were also by Trigger, specifically 1.0b11 for Lion/Mountain Lion, and after a restart they're working perfectly with the USB32HDE so far. So while I wouldn't recommend it, my bet is these devices are actually the same, and hopefully this helps anyone else who makes the same inadvisable purchase.

Does apple tv work with mountain lion without an hdmi cable?

Do I need to buy any cables to connect apple tv to my actual tv, in order to use airplay mirroring that mountain lion allows? Or do I simply need to plug apple tv into the wall and then wirelessly connect through the internet?

HDMI cables are dirt cheap if you know where to go.
Where to go: http://www.monoprice.com <--- 6' HDMI cables for around $3.

Hdmi adaptor not workin mountain lion

I´ve just recently instaalled OSX Mountain Lion and i noticed, when using HDMI it doesnt work anymore on my LCD.
How can i fix this issue?
Mac Book Pro mid 2010.

Just a random guess: Could Mountain Lion be treating the port as Thunderbolt while Windows is treating it (correctly) as mini display?
