Imac 5k @ 4k tv 60 hz? hdmi adapter?

can iMac 5k (retina) connect @ 60hz 4k on a LG tv 4k 60 hz 49ub820v?
right now my conclusion is no, because there are no hdmi 2.0 mini displayport to hdmi adapters at the moment.
i have tried both belkin 4k adapters in the apple store online and they only play 4k @ 30 hz.
the moshi 4k adapter says in their faq that they only support hdmi 1.4 4k @ 30hz.
the cable i use is hdmi high speed with ethernet.
may be someone else has succeeded?

That have enabled DP 1.2 on their monitor and used a DP 1.2 cable but still only get 30 Hz at 4K.
The MAC does not support MST

Cannot Connect Imac 24" via mini dvi to HDMi adapter cable to Sony Bravia 3

Hello Everyone,
I'm having the worst time in trying to connect the following:
1. Imac 24" 3.06 dual with dvi connection
2. Mini dvi to HDMI adapter (this mac with this connection was produced only for a short while!).
3. 10' (foor) HDMI wire
3. Sony Bravia 32" model KDL32L-5000 with 3 HDML connections
i.When I wire everything up, I keep getting"no signal" on my Sony Bravia TV.
ii. It doesn't matter whether I connect the HDMI wire to HDMI 1,2, or 3 on my Sony
iii. On my Imac Hard Drive>>Applications>>System Preferences>>Displays
all I get is a list of different resolutions. There is no mention or mirrors etc.
Nothing happens when I press "Gather Windows" or Detect Displays"
Can someone out there please help!!!!!
Can you also give any solution in very simple and small detailed steps!
Thanks,

Majortrout, there is a major disconnect going on here.
1. You are showing an Ebay link with a mini-DVI to HDMI adapter.
2. You report that you have an Early '09 24" iMac.
3. That iMac does not have a mini-DVI port. That iMac has a mini-DispayPort.
4. You need a mini-DisplayPort to HDMI adapter.
It is physically impossible to attach the adapter to which you link at Ebay to your iMac. So you need to take a step back and figure out what you really have; which iMac, which adapter, etc.

Hey Guys, from Germany. I want to connect my iMac 21" with my Tv just for fun. Does anyone know, how it works. With a Hdmi adapter?

Hey guys! I want to connect my Imac 21 " with my Tv just for fun. Does anyone know , how it works?

Selecting the correct adapter and cable depends on which year model iMac you have and what inputs the TV has?
Check the User's Guide that came with your iMac or your Spec's at > Apple - Support - Technical Specifications
to see if your iMac has a Mini-DVI or Mini DisplayPort and then select that adapter with the correct connection for the TV.
Example: if you have a 2010 or 2011 iMac and an HDMI ready TV, then you would want the > Moshi Mini DP to HDMI Adapter with Audio Support - Apple Store (U.S.)

I've just hooked my 20" iMac up to my Toshiba 37" HDTV using a mini dvi-HDMI adapter, and works well, EXCEPT for the green tinge (or hue) that is showing up on my TV. Any suggestions or ideas?

I've just hooked my 20" iMac display up to my Toshiba 37" HDTV using a mini dvi-HDMI adapter, and everything works well, EXCEPT for the green tinge (or hue) that is showing up. Everything else looks pretty good though..... The color that is on my iMac is still good, Its just green on the TV.
Anyone have suggestions or ideas?

Try opening the Display System Preferences, then click on the Color options in the Display preferences window that appeared on the Toshiba display. Click on the Calibrate button and follow the instructions for creating a custom ColorSync profile that will hopefully solve the green tinge issue. The Apple Display Calibrator Assistant software that launches when you click on the calibrate button will walk you through the process.Assuming that the green tinge is minor and that you don't have a more serious cable or hardware issue, I am hopeful the results will be worth it.

Mini DisplayPort to HDMI Adapter by Belkin for iMac 2009 failed to work

This is an SOS message. I have purchased another Mini DisplayPort to HDMI Adapter and I have iMac (27-inc, Late 2009) running OS X Yosemite (Version 10.10.1). I have carried out the connection of Mini DisplayPort to HDMI adapter to LG Plasma TV Screen, but there is no sign of any of the equipment reading or aware of the connection. Is there anybody out there who can help me make it work? Also, why is that Yosemite - System Preference, click on Displays does not contain - Arrangement? I'll greatly appreciate any useful tips from the community or apple support team.

Eric has helped in providing in dept understanding around the subject matter, but unfortunately, it has not provided the solution to the problem.
The Mini DisplayPort to HDMI Adapter when connected to the external Plasma TV screen, nothing happens. The System Preferences was accessed -and the Displays monitor sign was clicked, but it only showed - Display/Colour, which according to the instructions / descriptions contain in the - Video Troubleshooting Internal and External Monitors literatures and video, there seems to be missing - Arrangement / or AirPlay from my OS X Yosemite version.
The above is the version of OS X Yosemite - showing on my *iMac when clicked on System Preferences, and as result I have not been able to make the Mini DisplayPort to HDMI Adapter to LG Plasma TV Screen to work.
My *iMac is -
iMac (27-inch, Late 2009)
iMac10,1
(10.10.1)
MB952XX/A
Running OS X Yosemite
When the above image is compared with the following image below, there is definitely something missing and it’s probably affecting the Mini DisplayPort to HDMI Adapter to work in my connection.
Questions:
How can I make my iMac 10,1 (27-in, late 2009, currently running OS X Yosemite 10.10.1) to have the above AirPlay mirroring or Arrangement to activate the connection?
Are there other ways I can make the connection to work?
Is there any body who has a similar iMac specs and OS X Yosemite who has overcome connecting to external Plasma TV Screen?

Mini DisplayPort to HDMI Adapter ... yes or no

Hi
Is it possible to use a Mini DisplayPort to HDMI Adapter like this one to connect the HDMI out port on my Nokia N8 to my 27" imac?
http://www.monoprice.com/products/notify.asp?cid=104&cp_id=10428&cs_id=1042802&p_id=5311&cmd=ansubmit
Thank you

You are right: Thunderbolt supports both Mini DisplayPort cables and adapters without any problem, but Mini DisplayPort does not support Thunderbolt cables.
If you have got an Apple display with Mini DisplayPort, you can use it with the new Mac Pro. Just use the Mini DisplayPort cable or adapter you need. See > http://support.apple.com/kb/HT5219?viewlocale=en_US&locale=en_US#22

My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter.

My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter. I also tried the HDMI to DVI adapter ane the Mac-Mini with same result. The monitor does work on my older Macbook Pro that has the DVI connector. Is it a Software/Driver issue ?

Should be extremely simple, please carefully read Connect multiple displays to your Mac. If you still have problems then it's probably a cable issue that would be resolved by replacing the adapter cable. You should be using this adapter. If you are using a third party adapter that might be your problem!

Is HDCP protection always on when using Mini DisplayPort to HDMI adapter?

I'm trying to capture my MacBook Air (2010) desktop for use in a Podcast.
So I purchased a Mini DisplayPort to HDMI adapter and plugged that into a HDMI capture card on another machine.
Unfortunately it keeps telling me the stream is protected and it won't display anything.
I've tried my 2010 iMac and 2011 Mac Mini too, but they all produce the same issue.
If i plug them directly into a TV instead then they display fine, but not when connected to the capture card.
A windows based laptop with HDMI out works fine as does a DVD player. But when I attempt to play a cop protected DVD - then the HDCP kicks in and the picture is blocked.
Does anyone know if there is a way to display just the Lion Desktop without invoking HDCP protection?
Thanks in Advance
Anthony

Is the failure repeatable? If not, I would forget that it happened once and move on. It had something to do with pages moving in and out of the registers. S**t happens.

Dynex Displayport to HDMI Adapter works Win7, not 10.6.7

Hey, all,
I have an interesting problem. I have a 27" iMac, 3.2GHz i3, I think mid-2010 release. It is running 10.6.7, and Windows 7 Pro 64. Windows is booted using BootCamp. I also have an older Apple 23" Cinema HD monitor. I bought a Dynex Displayport to HDMI adapter yesterday and hooked the 23" monitor to use a 2ndary display.
When I use OS X 10.6.7, the external monitor turns on but doesn't display. It is detected:
Displays:

When I boot Windows 7 the 23" monitor works fine.
I've tried resetting the NVRAM, and that didn't help.
Anyone out there have any idea why this is happening?
Thanks!

IMac 2011 Thunderbolt - iWires MDP to HDMI

Hello all - I've had a good trawl through the communities and am unable to find a fix for my issue.
I've recently upgraded from a 2010 mac mini, with HDMI to a new iMac 2011 - which has the new thunderbolt port.
By my understanding, this will enable me to use the Thunderbolt Port - identical to the old Mini Display Port to output HDMI to my HDTV.
I've bought a MDP to HDMI adapter (http://store.apple.com/uk/product/H2774ZM/A/Mini-DisplayPort-to-HDMI-Cable-2m)
But my mac will not recognise my TV, no matter which way method I use.... ie turning tv off and then plugging in to the mac..
Do I have a dodgy lead / dodgy mac, or both!?
My intention is to swap the lead at the apple store - and see what happens... but in the meantime, I thought I'd pick your brains!
Cheers,
Tom

Fixed.... turned both the tv and the imac off and on a few times.. eventually worked and is fine now. I can also confirm that the sound does work perfectly!

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.

My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. A while ago the computer fell down and hit the cable. How can I tell if the computer is working ok. Doesn't show mirroring any more.

My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. A while ago the computer fell down and hit the cable. How can I tell if the computer is working ok. Doesn't show mirroring any more. Was working while watching a movie but when I pulled it out from the computer and put it back in the system would no longer mirrorr the screen on the TV.

The best option is an appointment at an Apple store genius bar. The evaluation will be for FREE!
Ciao.

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.

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.
