Can you help? 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. 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.
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 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….
How to Plug a MacBook Into a TV & Get a Picture
Thank you!! You saved me hours!! So glad I found this. I also need both the other usb slots for my mbox and ilok. 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.
Configuring the TV display
I have a MacBook inch, Mid 2. I guess it could be a substandard adapter cable but it could be something else too.
Good stuff. This helped ease the pain. However, it works great now and the picture is very acceptable. Not sure where I am going wrong frustating. But now when I try and connect, the connection of my desktop on the TV screen only lasts for a few seconds, and it goes blank. It will flick back on for a second, and then go black again for a few minutes. I had the same problem with my Macbook pro and TV.
I was worried it was the TV or the Mac, which are both much harder to fix, but it turned out it was the much cheaper Mini Display Port Adapters so just get a new one. Opened my system preferences and then sound, but there is not an HDMI option listed. Internal speakers listed only. Any ideas? I have the same problem.
I think external speakers are the answer unless some clever person out there has a solution. I have the same problem as well. Someone please help, I can see the video but have no audio. I found your instructions great, but I had a problem the screen on the tv has a pink tinge to it. Any suggestions. Many of the cheaper adapters for display-port to HDMI do not support audio, you have to buy an adapter that specifically does support audio output. Thanks so much for this. Just got a 23 inch monitor and was all good for mirroring but was getting the black box when playing videos — which was the main reason I got the monitor.
After switching the main monitor to the display as you suggested … Perfect! Thanks for the clear and useful help. Thanks Paul! Name required. Mail will not be published required. All Rights Reserved.

Examine the ports on the MacBook, or consult your user guide to determine what type of video cable you need. MacBook video ports have a video icon beside them. DVI ports have a set of 24 square pins, with four square pins beside those. Examine the TV to see what type of video cable you need for it. Select a single cable if possible to connect the MacBook video-out port to the TV's video-in port.
In most cases you need a cable that works with your TV as well as an adapter to connect the cable to your MacBook video-out port. Decide how you want to listen to sound while the MacBook is connected to the TV. Although the TVs HDMI port is designed to receive sound, sound may not be transmitted from the MacBook's video-out port, depending on the specific model you have.
Alternatively, you can connect external speakers to the MacBook. Turn off the TV and connect the video cable to the TV video-in port. Connect the adapter to the cable and then connect the adapter to the MacBook video-out port. Wait a couple seconds for the MacBook to automatically display its screen contents on the TV.
Select "Mirror" to show the entire screen on the TV. You can also adjust the resolution and screen size if desired.
