HDMI/TV/wifi/macbook
When I connect my macbook to my TV, sometimes I lose my wifi connection. As soon as I disconnect it, the wifi comes back....can anyone help me fix this problem?
Hi allison5479 & welcome to the forums!
It's a problem with the adapter not being properly insulated, causing the signals to interfere with each other. Contact the manufacturer to return or exchange the adapter.

Trying to plug in an hdmi tv to macbook pro rentina and it keeps trying to adjust and just flashes., Trying to plug in an hdmi tv to macbook pro rentina and it keeps trying to adjust sizing and just flashes and never stops.
Any help?First than all, check your video input (TV Video), check in all possible channels, and make sure the HDMI is plugged in correctly. If you did plug it in correctly, and checked all possible channels of Video Input, and it doesn't appear, you should try rebooting your MacBook Pro (with the HDMI disconnected), after it's back on, try plugging it in back again. If the problem persists, I recommend you to go to a Certified Apple Store, and have them check it.
Hope this helps!

Tv Receives No HDMI Signal from Macbook
Hi Everyone,
Recently I bought an HDMI cable and a 'MiniDisplay Port to HDMI Adapter' from Rocketfish in order to use my Tv as a large monitor. However, when I plug the adapter into the port followed by the HDMI cable my Macbook's [Late 2011 model running with Mountain Lion 10.8.2] screen turns blue for a short moment and the TV seems to acknowlede the input because it immediately pops up a window stating that there is No signal, sometimes also the screen just goes black. Sounds nonsensical yet the tv does acknowledge the Imput by stating that there is no Signal.
Has anyone ever had this happen too ? Is there perhaps a better way to connect a Macbook to a TV ? At this point I am willing to invest a lot more money just to make it work.Hi, mtobler!
I have the same problem. The only difference is that I am trying to connect to an external display using Mini DisplayPort to VGA adapter. I have tried with two different displays - a TV, Samsung C8000 TV; and TV-Monitor, Samsung SyncMaster P2470HD, both of them with no success. When I connect the adapter the screen turns blue for a second, the TV, just like yours, says 'No signal' and the Mac itself does not find any external displays. I have tried a variety of solutions - resetting PRAM, SMC, but nothing helped.
The AirPlay is not an option for me, because I want to use the Mac with projectors (HDMI adapters are not a solution, because most of the projectors I use are old and have VGA ports only).
I will try connecting it to a projector tomorrow. Let's hope it runs smoothly. -

HDMI port on Macbook Pro suddenly stopped working. How much is it to fix?
HDMI port on Macbook pro suddenly stopped working. Is it expensive to fix?
No one here can tell you what the prices are to repair things. We are just users such as yourself.
What makes you think your HDMI port is dead?
You can take it to a Genius Bar for a FREE diagnosis, make an appointment first.

Also check system preferences/Displays make sure that you have all the correct settings.
Check that the cable you are using is good.
Make sure the display you are connecting to is set correctly.

Try resettind SMC:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
. RESET PRAM:
Shut down your Mac.
Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on your Mac.

Help using a mini display port to HDMI cable with MacBook Air and TV
Hi, Apple gurus. I need help setting up my MacBook Air to my Vizio TV using a mini display port to HDMI cable that I just purchased on Amazon.
And here's info about my MacBook Air:
In the Amazon reviews, someone posted the following how-tos, which aren't working for me:
1. Plug in both ends, mini display port on your macbook and the HDMI on any available port on your LCD.
2. Go to upper left Apple menu and scroll down to system preference. Or use your FINDER from the dock, go to applications, then system preference.
3. Click on Displays
4. Click on DETECT DISPLAY
5. A similar screen pops up with name of your LCD, mine says SONY LCD, click on ARRANGEMENT
6. Click the box that says MIRROR DISPLAYS.
7. Go back into system preferences and go to SOUNDS which is located under HARDWARE.
8. Click on OUTPUT, then select HDMI, which should be listed next to your LCD name.
I ran into trouble at step #4. My MacBook Air doesn't list the option of "detecting display." I do, however, have the box mentioned in step #6, "Show mirroring options in the menu bar when available."
Regarding step #8, HDMI didn't appear in the list — I only see "internal speakers."
So, what am I doing wrong? Or, did I buy the wrong cable?
Thanks in advance for your help!Or you need to get an appropriate adaptor. The Griffin adaptor sold on Apple's Online Store will work with a standard HDMI cable.

Redskins40It would help to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up check the Model Identifier and post it back here.

HDMI failure on MacBook Pro Retina Display
When I connect my MacBook Pro Retina Display (late Aug 2012) with HDMI cable to my HD TV their both screens turn blue and the Mac needs reboot. I used that same TV with my 3 yo MacBook Pro to watch over the HDMI (with some extra cabling) and it was fine. Why is it happening this now with the New Retina dispaly?
Hey, I have the same problem too. It is making me angry. Both my thunderbolt outputs work, but the hdmi freezes both screens. I then have to shut the computer off by holding the power button and re-boot. Have you found a solution? I NEED my hdmi port. Please get back to me. Thanks!

Connecting Dual Monitors: HDMI & VGA to MacBook Pro (Non-Retina)?
Whats up Apple Fam,
So i have a MacBook Pro along with a LCD TV i use as an external monitor and its connected via Mini DisplayPort to HDMI adapter.
Now, i’d like to add an additional computer monitor, the cable coming out of it will be a VGA. Hence my question; what type of adapter will i need to accomplish my goal while achieving it at the lowest price possible?
My only concern is that the Mini DisplayPort is already being used by the LCD TV. So i’m a bit unsure what to do. Any help is appreciated. Thanks !You could purchase 2 mini displayport to DVI adapters ($30 ea) and use the 2 Thunderbolt ports. I have one external DVI monitor connected to 1 of my Thunderbolt ports. Works great!
Sorry my mistake. You said non-Retina. -
LG IPS display with HDMI plugged to Macbook Pro worked only once
Hi!
I bought this display (http://www.lg.com/us/monitors/lg-IPS237L-BN-led-monitor).
I plugged it to my Macbook Pro 13 with Mac OS X Mountain Lion updated to the latest version using a HDMI cable and a HDMI to Mini Displayport conversor. It didn't work the first time, but after searching in the forums i tried deleting the file /Library/Preferences/com.apple.windowserver.plist and it worked! Later on my Mac ran out of baterry and shutdown. I turned it on again but since then, i haven't been able to get the display working. It just says "no signal", and i can see it gets recognized in someway by Mac OS because when i plug it or turn it on the laptop screen goes blue, but then nothing happens and i can't find the display under System Preferences > Displays.
I have tried the following:
- Deleting all the files related to com.apple.windowserver.plist (including those under ~/Library/Preferences/ByHost)
- Delete also those files in single user mode and also in verbose mode.
- Deleted Overrides files for displays (/System/Library/Displays/Overrides)
- Restarted in Safe mode.
- Deleted .GlobalPreferences files
- Reset NVRAM and SMC
- As a last resort i tried reinstalling Mac OS. That didn't work either.
I have tried those and a couple of things more that i can't rememeber, but at this point i'm clueless. I guess my Mac is caching something related to the display and that's why it doesn't work. It's not certainly a cable or device problem since i already could make it work once.
Any ideas what could i be missing? I'm pretty sad i can't use my new display! Any help appreciated!It was the **** cable. As it worked once, i never cared to test with another one. As soon as i did, it worked. So many wasted hours but pretty happy now.
