Crashing when viewing video using Mini Display port
My 13" MacBook Pro (Model Identifier: MacBookPro7,1) with the NVIDIA GeForce 320M, frequently crashes when using the Mini Displayport. This occurs when using a Mini Display to DVI cable, which is then connected to a DVI to HDMI adaptor and Toshiba rear projection CRT TV with HDMI input. The MacBook Pro always recognizes the TV normally and displays a second display.
The crash occurs either during video playback but more frequently *when ending playback on the TV*. It frequently crashes with a pink/magenta screen on the MacBook Pro. The freezing is a hard lockup, completely unresponsive and requires me holding the power button down for 5+ seconds to recover. It doesn't matter if it's a DVD playing or video file of some sort.
The DVI to HDMI adaptor and TV's HDMI port otherwise work flawlessly with other devices, including my previous G4 based laptop with DVI out.
I have a similar deal. I'm using the MiniPort VGA adapter for a secondary LCD screen and it crashes in the same fashion, sometimes it takes 30 mins, sometimes it takes 8 hours for it to happen. Please let me know if you figure out a solution, i'll do the same.

MacBook suddenly won't detect my display, Using Mini Display Port to VGA?
MacBook suddenly won't detect my display, Using Mini Display Port to VGA?
dohdoh1985, I have the exact same problem also! I recently bought a 42" RCA LCD TV. I connected my MacBook Pro to my TV using a Dynex Mini DisplayPort to HDMI adapter that I got from BestBuy. It worked great until I upgraded to Mac OS 10.6.4 and then it suddenly stopped working. Same TV, same settings, same cables, same adapter. Nothing changed since the last time it worked except that my OS was upgraded to 10.6.4, so i am assuming that is the culprit. The symptoms are EXACTLY the same as what dohdoh1985 described; when I plug in the TV, the laptop display flashes (3 times) as though it is detecting an external display and the picture on the TV briefly goes from blue to black for about 1 second then back to blue. The TV does not appear in the display menu / control panel and there is no sign that the MacBook detected it. I went through the usual troubleshooting steps (reset PRAM, checked connections, tv settings, etc) but nothing worked. Other HDMI sources (i.e. Blu-ray player) work fine on the TV using the same HDMI cable on the same port so there is nothing wrong with the cable, the TV or the TV's input settings.
Meanwhile, I can still connect my MacBook to my external ViewSonic monitor at work without any problems. It's just the TV that's not working.
I cancelled my cable subscription a while ago since I only watch shows online nowadays and this was my only way of watching TV shows, so I'm quite upset.
Apple, please help! -
How do I use a VGA adapter with my MacBook Air when it has no mini display port?
I bought this http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=200968578311 to connect my MacBook Air to a monitor but it only works in a mini display port instead, and my MacBook Air doesn't have one. What kind of adapter can I buy instead? It looks like lots of adapters are wrongly described on eBay as fitting all Macs when they don't Help gratefully received!!
If your computer has a Thunderbolt port, plug it in. Otherwise, check what type of display port your computer has and get an adapter for it.

IMac does not recognize external monitor using Mini Display Port to HDMI
Hello,
I have been trying to get an external monitor (HDTV) set up for use with my iMac using a Mini Display Port to HDMI cable I just got. However, when I connect it to my iMac's mini display port, the imac's screen goes black for about a second, then returns, but it does not detect the external display. The other display is just showing a "no signal" message on the screen.
I have restarted, reset PRAM, connected and disconnected the cable several times, tried changing the resolution on the imac, plugged in/out the other display, and clicked the "detect displays" button using the option key in display preferences, but nothing has worked.
I am using an early 2009 iMac running Mavericks.
I've been using the AirParrot app, but it's horrible for video and a little slow.
Can anyone please help sort the issue here? I feel like ive exhausted everything that I know to do.
Thanks.I am having the same issue. Hope Apple can fix this soon!!!

What do I needto do to connect a tv as an external display for my mbp using a mini display port to hdmi cable. I have tried display without success. tv is receiving a signal as displays apples default wallpaper when connected but nothing from screen of mbp.
Soundls like it is working. Try dragging a window on the MBP to the edge of the screen and see if it appears on the TV.
There are two ways to set up the TV one is to mirror the MBP display and the other is to be an extension of the MBP's screen.
You change the settings in System Preference->Display -
No Display on HDTV using Mini Display Port to HDMI Cable
Hi,
I have a Mini diplay port to HDMI cable Male to male cable. I am trying to connect my Macbook Pro running OS 10.6.4 to my LG 32inch HDTV and cannot get display onto the HDTV.
The screen just blinks for a bit but still no luck. I have searched a number of forums and am still looking for the appropriate steps.
Is there any configuration that I am missing?
Please advise.Hi,
I currently have the same problem, but have found a temporary solution while looking for a permanent one. The temporary solution involves resetting the SMC. To do this follow these steps:
-First connect the cable to both your TV and your MacBook Pro and make sure both are powered on.
-Then shut down your MacBook Pro
-On the left side of your keyboard press command, alt (option), shift and the power button at the same time, holding them for a second and then releasing them at the same time.
-Wait about 10 seconds and then power on your MacBook Pro, the display should be detected and working.
As I said earlier this is only a temporary solution and I am looking for a permanent one, so any more help would be appreciated.
Let me know if it works or not.

Macbook Pro Crashes When Viewing Video
My 2008 Macbook Pro 2.4Ghz crashes frequently when using video, such as YouTube or video on iPhoto. The screen instantly goes black and a hard button restart is required each time. I can't find anything in console logs which could help me identify the problem. After doing a hardware test and not finding anything I zeroed the hard drive and reinstalled 10.6.8 and only a minimum of applications - MS Office 2008, Flip4Mac WMV and iLife '11. Still the problem continues.
Do you think it's the video card (GeForce 8600M GT) or likely some other problem?Hi there, I have the same problem as you guys, everything was fine before iTunes 7.6 or iTunes 7.6.1 I tried both, before those updates I could watch any video in iTunes without any issue, after that when I play a video, a random video my Macbook freeze totally, sometimes comes alive but 90% of the cases I have to make a hard shutdown (press and hold the power button). I can't believe this kind of bugs in a software that is so mature. Help please!

Adding second display via mini display port
How do I add audio and video using mini display port and USB audio with HDMI connection at Home Theater Receiver from 2009 Mac-mini? DVI and optical audio outputs on Mac-mini used for primary display.
Assuming your receiver has a USB audio input, you would use an Apple Mini DisplayPort to DVI Adapter and then a DVI to HDMI cable for the video and a USB cable for the audio. You would have to go into System Preferences/Sound and under the Output tab you would have to make a selection to direct which port to send audio out of.
As an alternative to the Apple adapter, there are also third-party Mini DisplayPort to HDMI cables that avoid any need for an adapter at all.

MBP 15' 2011 Mini display port to LED monitor/TV resolution issue
Hello,
I have just bought a Mini Display - VGA adaptor which I am plugging to a Samsung 23' LED monitor via a VGA/DVI adaptor. I manage to get a clone view but unfortunately, the maximum resolution offered is 1650x1050 when my Samsung LED monitor has resolution of 1920x1080. Therefore, part of the screen remains black.
... also, when I plug the Mini display port to VGA to my Philips 47' VGA port, I got a message that there must be a problem with the connection and again, maximum resolution offered if 1440x10.. and therefore 20% of my TV screen space remains black.
At last, when I launch Windows7 via bootcamp, this is even wost : when I select the max resolution (1440x10..), the pictures remains freezed on my TV and I can't even move the mouse (while the mouse is moving on the MBP screen...). Only coming back to a very small resolution 800x600 or so will enable me to get control of the win7 desktop on my TV...
Thank you in advance for your help

If you are using the monitor in Mirrored mode, its resolution setting will always be exactly the same as that of the built-in display. I presume you have the high-res 15" MBP display, with a native resolution of 1680 x 1050. If that's true, I suspect your monitor is indeed in Mirrored mode, and that's why you can't set the monitor to its native 1920 x 1080 resolution. If you press Command+F1 to toggle the mnitor into Extended Desktop mode, you'll be able to set its resolution independently of the built-in display. Or if you use only the external monitor, with the MBP display closed, you'll be able to set the monitor's resolution to whatever it supports.

Stacking one video adapter on top of another is usually a recipe for trouble. It's always best to keep things as simple as possible. Use one adapter that gets you from mini-Displayport to whatever input you want to use on the TV or monitor. -
I used mini display port to connect my macbook to my HD tv.. when i connected it worked perfectly with sound via the hdmi cable.. but when i changed the channel and than changed back the audio stoped working... now only video is working no audio.. my mac recognizes only the internal speakers..
try to restart mac , tv , reinstalled os , everything is updated.. cant find a solution...
plz help...The MB has a Display Port which is used for external displays. Not input at all.
Your camera either has a Firewire or a USB port. If it is a firewire you are out of luck. If it has USB you can get an adapter.

Extender for Mini Display Port. Need help.
I am running a setup with a 30m optical extender for DVI. I have just upgraded to the 8-core Mac Pro with 27" display which uses mini-display port. But that will give me maximum 1920x1200 resolution that is way too low for the 27" and I have to buy a converter from mini-display port to DVI.
Is there any available extender cables for mini display port (30 meter)?that will give me maximum 1920x1200 resolution
To go higher than 1920 wide, you need Dual Link. -
im having trouble connecting my macbookpro to the tv. im using a mini display port to hdmi adapter, when i switch tv/video to hdmi on the tv nothing pops up, and i dont have the arrangement tap on the display settings, please help!
I've found that the order of operations, so-to-speak, can be important when hooking up mini display port to HDMI. I have the most success with the following operations in this order:
1) Plug HDMI cable into mini displayport adapter (the cable should not be plugged into either the TV or the computer at this point)
2) Plug the mini displayport end of your new super-cable to the computer.
3) Plug the HDMI end into your TV.
4) Switch inputs on your TV to the proper input.
5) If still nothing on the TV, try a different HDMI port on your TV.
Hopefully this helps! Good luck. -
When I connect my Macbook Air to my TV via the thunderbolt outlet and using a Mini Display Port/HDMl adaptor, the only image that appears on the TV screen is that of my Air background. There is obviously a signal getting through to the TV, but it is not sending images of anything else, and am unable to watch video through my Air. Any advise/suggestions?
This is called "extended desktop mode". It's an extension of the desktop off to the right (by default) of your MBair screen. Grab an app and drag it off the right side of your MBair screen and it will appear on the TV.
To mirror your MBair screen on the TV you can press Command F1. This will toogle between mirror and extended desktop.
You can find all the settings in System Preferences > Displays > Arrangement tab.
