It was working fine for so long with the same tv with no issue. Also I have my Amazon FireTv connected via hdmi with no issue. Sorry I didn't try ThnderBolt.

HDMI port stopped working

I have a MacBook inch, Mid 2. I guess it could be a substandard adapter cable but it could be something else too. I am having almost the exact same problem as Jason. My computer flashes as well as though it recognizes that something is happening. I do see pages as Option A and Option B above, and I see an option of optimizing the display for a Samsung on my computer, so there is something going on, but no video.

I also need both the other usb slots for my mbox and ilok. Thank you!! You saved me hours!! So glad I found this. I have had my Mac Air hooked and working and suddenly now it wont work when I attach it to my tv.

I have the correct input and the cables are fine…could this be an OS X update issue? I have not updated Yosemite…. I primarily want it to push secondary screens containing documents or watching a youtube etc.

My issue is the fonts on the iMac have all changed, everything is now much smaller. The safari browser fonts, email, ichat, calendar……everything now has much smaller font.

Moving a safari browser over to the bigger tv works fine, but the iMac is my primary display in this case and I need to be able to read without a new prescription: I have a problem with Audio; display works just find and has no issue at all but I have checked all possible options but audio still does not work. Nothing works to get video back. However, after about 5 minutes the video signal returns inexplicably.

I can still switch my port to Apple TV with no issues with video or audio but when I return to mac mini, my screen is still black. Also I have a magic black mini recorder Capture Card. And I want to live broadcast Wirecast ,however no sound is being picked up, when I connect the canon to the MacBook. Can you help? I did it successfully before the upgrade.

What do I need to do? I tried to connect my macbook pro retina display with my 4k TV but I can only hear the sound on the TV and only the home screen of the macbook can be seen on the TV.

Great tutorial! I tried one suggestion that I read from the feed by going into preferences and switching output to hdmi but this did not resolve my issue. I have a presentation for tomorrow and this has become really stressful. Can you please assist to resolve my issue?

Does anyone have any ideas for a solution? I have a My daughter put my evening eye glasses inside the notebook and closed it, cracking the retina display, which pretty quickly spread to almost the entire screen. I do have apple tv and had been connecting that way but now it is difficult to even find the display settings to setup mirroring. I figured the easiest and quickest thing would be to just hook up directly through an hdmi cable since I have a small flatscreen I can use as a temporary monitor on my desk that has an hdmi port and my Powerbook has an hdmi port also.

How to Connect a Mac to a TV with HDMI for Full Audio & Video Support

I expected to just plug each end in, switch to the hdmi input on the tv and have my desktop on the tv. I mean, it is a pretty basic and uncomplicated setup. However, I have no picture. And the Mac is not recognizing the tv at all as a device it is attached to. If I go to displays, only the internal retina display is listed. In sounds, only the internal speakers. Nothing else under output. It does not make sense to me as it is directly connected securely on both ends through a brand new HDMI cable.

I have triple checked that each end is securely inserted in the ports. The small tv only has one hdmi input channel. And your instructions confirm that I have correctly set it up and should see my desktop. Does anyone have any ideas here? I need to get my Powerbook fixed but while I am waiting on that, it would make life so much easier if I could use it at least part of the time with this smaller tv as a monitor rather than mirroring to the bigger tv with apple tv…. I restarted also with the tv on, correct hdmi input selected and cables hooked up….
