Q: Mini display port to HDMI problem

all i can get to show up on my tv is my home screen of my mac nothing else will appear ? is there a reason for this

Hey I responded that before just look for my user names johnbello05, I had the same problem!

You just made my Christmas complete ! Thank you !

im glad, Merry Christmas!

Hi everyone!  I'm using a Macbook Pro Mini Display port to HDMI.  I just hooked it up and it goes fuzzy for a second, then shows a split second of a mac desktop.  While I was messing around in the settings I could see my windows appear in the breif second it works, and then the fuzz repeats every couple seconds.  It's really annoying.  Any help would be appreciated.  I'm using a TIVA TV w/ a 2009 Macbook pro and the MINI DISPLAY PORT TO HDMI.  Thanks in advance. 

any ideas as to why my tv isnt in the sound output box ?

Here's a link to the problem I'm having.

As you can see, the TV goes fuzzy then clear every second or 2.  Please let me know if you have any ideas.

Thanks, Aaron

hey here is what you do:

well after doing the first steps that you did before to get the video image  on your tv:

go back system preference

under the hardware items you will find the sound, click on it

you will have three options, the one you need to click is the output

if you have the tv connected before you start doing all these steps and you were able to see the image on your tv, you should have the option on sending the audio to your tv... for me on this step i clicked on Sony HDMI, but for you it will be whatever your brand name tv which i forgot and HDMI..good luck!

i watched your video, im just a regular macbook user, but i did notice you have an aptapter with the HDMI cable which i dont, my HDMI cable is connected directly to the thunderbolt.

just try to go to the system preference that you can find below on your screen

click over the display image

make sure the arregement is check on the mirror displays

and may be try detect display under the display section!

this could be due to the HDMI cable not being truly High Speed. Apparently this is a common problem when cables are not rated/ have a fake rating. I bought a SONY HDMI 1.4 Flat cable due to this reason and mine is working well .. tested to 1080p... sorry I do not know about this HD stuff

Solved. I have a Dell u2711 and had the same Problem. Macbook Pro 17" from 2010 with a Logilink male miniDisplayport to female Displayport Adapter. It worked only once and after I reconnected the cable with adapter the display would only turn on and then off again.

Before I reconnect the display to the macbook I pull the power cord from the display. (Actually I just switch off the multi socket power supply). It works like a charm. Every time.

What worked for me is to reset the NVRAM.

I just go my Mini displayport to HDMI and it registers and works no matter what like it will show a background and if i swipe over to my launchpad it will do that to. the problem that i have is that 1. it's not even the same background that i have on my computer, 2. it won't show the actual windows that i have pulled up on the screen or videos. 3. in the launchpad it doesn't show any widgets or anything, just the backgroud of it. i don't understand why this is. if it's going to display something from the computer why would it not display everything?... if anyone has any ideas it'd be appreciated.

You have the display set in Extended Desktop mode. 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. 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.

I have a Macbook with OS 10.6.8.  I recently bought a Panasonic HDMI TV and want to hook my Macbook up to it.  I was told to buy a mini display port to HDMI cable, which I did.  I plugges it into my laptop and then into my tv.  The laptop blinked a bit with a blue screen and then came back (I understand this to be normal), but nothing shows up on my TV.  The screen is blank and reading no signal detected.  On my laptop when I open the systems preferences and click on display it shows that it is connected to Panasonic TV.  The mirroring option is selected and it is on resolution 1080p.  I have tried other resolutions, but nothing happened.  I have tried turning tv off and on...nothing.  Same with laptop.  It seems like the Macbook recognizes the tv, but the tv doesn't recongnize the Macbook.  With some of the other posts, I wonder if the mini display port to HDMI cable will work with my MacBook?  I went to local Apple shop and they said it should work and had no ideas for me.  Anyone figure this problem out before?  Thanks.
