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.

A video "splitter" does not work, you must use a video distribution amplifier like this:

Will mini display port to HDMI be HD?

I would love a cinema display but its too expensive. There are other companies that make hd displays for much cheaper. There are companies that make adapters for mini display port to HDMI. I am wondering how clear it will be and if it will be hd.

Yes. HDMI can handle up to 1920x1200

How can I connect multiple devices to Mac mini display port? I need to connect a Canon 5D to my Mac and display the result on a VGA video projector. I am using mini hdmi to mini display for the camera. Can I connect the VGA to any other port?

Hi there I am connecting a Canon 5D to my laptop trying to use it as a webcam trough camtwist.
At the same time I need to output the streaming to a videoprojector.
The cam is connected to the mini display port do there is no port available for the VGA cable anymore.
Do I need to use a different port for the projector? Should I buy a video card?
Can't connect the camera via USB as that is too slow and it will freeze.
Many thanks for all your help

Mini display port to HDMI problem...still happening, apple needs to help!

i read a lot about this topic and the question was marked answered, but there was no answer, sooo...
this is just a heads up to apple that this problem still exists and many people are still having it! Please do something... you put this mini display port on your computers... sold them to us... and now dont have software that lets it work... loosing a lil faith in apple today! there were 11 pages on this that i saw, i think it deserves a firmware update!
this next part is a direct copy of a post by sanktcolon and he explained the problem very well, so if your interested...
I figured I would just tell you all about my story. I do not have any solutions, the problem is still ongoing. But first I'd like to clear some confusion.
There seem to be a couple of people in this thread who thinks that when you experience this problem and you plug the HDTV with your MacBook through HDMI, you get a connection with the HDTV and can change the settings. This is not true. What happens is that the MacBook will flash its screen like it does when it detects a TV being connected, but then it will go back to normal. No connection established. Of course, there's people in this thread with different kinds of problems but with similarities. However, the main problem in this thread is quite clear and it's the same one that I have.
So with that out of the way, here's what happens for me and most people in this thread:
I've been using a Mini Display Port to HDMI adapter for quite a while and it has been working great. But lately I've been experiencing issues with it. There is nothing wrong with the adapter nor the cable, and certainly not the TV.
When I connect the adapter to the computer, the screen on the MacBook will flash blue, like it should, but it will not connect to the TV. What does this mean? It means that it detects the TV but is unable to establish a connection with it. Probably because it sends the wrong signals.
Now that's all pretty logical, but here comes the weird stuff. If I continue to try and re-establish a connection, either by plugging in and out the cable or changing HDMI-ports with the TV-remote (the MacBook re-detects when I switch from HDMI1 to HDMI2 and back), it will eventually establish a connection with the TV and work fine. Though, this can take minutes. Plenty of minutes. Last night I tried re-detecting for about 15 minutes and it didn't work. However, this morning it worked quite quickly.
So the problem is quite obviously with the MacBook/the OS and not with the adapter, cable or the TV. It's just ridiculous, and frankly quite annoying, to read posts where people claim you should get a new adapter. Why? Because there's so many people out there with different adapters, and people who have switched adapters and so on and so forth, that experience the exact problem I just describe. So either there's a problem with the MacBook/OS or there's a lot of TVs and adapters out there that are faulty. It's just illogical.
Once again I would like to remind you all that there's no connection, what so ever, between the TV and the MacBook when it doesn't establish one. And by establish I mean that you can actually see the screen on the TV. So bringing up the display settings won't do anything, search for devices on the TV or in the MacBook won't do anything. There just is not a TV there for the MacBook.
I have tried everything posted in this thread and the only thing that works for me is trying over, and over, and over, and over again until it just randomly works.

I too am having this same problem with my Macbook Air (Late 2010 Edition). I think this has something to do with OSX 10.6.6. Before the update, my mini display to HDMI was working flawlessly. Now, when I try to plug in to the TV my macbook just flashes the blue screen with no picture going to the TV what so ever. I'm not sure what was done with the update, but i'd sure like to be able to connect this machine to the TV again! APPLE, HEAR OUR VOICES! Fix this problem!

Need a mini display port and audio to HDMI adapter for mid 2009 13" macbookpro

Can some body recomend an adapter cable that plugs into the audio (mid 2009 MacBookPro 13") and mini display port and outputs to HDMI with audio and video all together for a TV? I would rather not run a separate audio cable in addition to the HDMI cable.

I have a Samsung HD TV and I purchased a Mini Display port to HDMI Adapter today. For some strange reason I get no display on my HD tv. I even tried switching a few HDMI cables and nothing popped up. I made sure my computer was updated. Help pls

I have a Samsung HD TV and I purchased a Mini Display port to HDMI Adapter today. For some strange reason I get no display on my HD tv. I even tried switching a few HDMI cables and nothing popped up. I made sure my computer performed all software updates, and I even tried calling Apple Support. They just told me to keep trying different hdmi cables and see if anything pops up. Does anybody know what the problem is? My HDMI cable is from "rocketfish" also my display port is too.

You may have the screen refresh rate set higher than the TV is generally able to track reliably. It may be able to get there most times, but occasionally loses sync because it is out of its nominal range.
I suggest you sit down with the manual for the TV and find out what resolutions at what refresh rates it intends to support through VGA, and make sure your screen settings are near (or below) those limits.

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.

I need to connect a computer monitor to my MacBook Pro but have found that when using the mini display port to VGA adaptor the screen display on my macbook is very small font. Please what do I do to correct this?

I need to connect a computer monitor to my mac book pro, using a mini display port to VGA adaptor. But have experienced a drastic reduction in font size on my

18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

How can I detect displays?
If the detect displays option is not available, hold down the Option key while you are in the Display pane.
How do I select additional resolutions on my display?
You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.
I hope this information helps ....

Mini display port to HDMI...help

I have all my options selected and was just about ready to click purchase on a new 2010 17" MBP and thought I would double check one more thing...Mini display port to HDMI with audio.
I see many post about this, but most seem to be on 08 models...have the new ones changed? I am more less getting this for my wife to use and she needs it for presentations. I finally got her to go from PC to my old 17" G4 laptop and it's time for an upgrade. The one issue we run into is that files are commonly sent as Power Point, but we got through that with a Mac/Microsoft upgrade.
I am told the location that these presentations are displayed, plans to get a new monitor and they are looking at BestBuy and such for TV style monitors with the HDMI option. This seems like a cheap way to get away from the projector system they have now that only supports S-video or VGA. I'm hoping that Apple now supplies audio thru the HDMI cable which is in my (limited) understanding the main reason the change over from DVI to HDMI was implemented in the first place.
If the no audio issue is still a factor, maybe I should put off the new MBP, because I am trying to get away from having to make the trip with her, in order to make sure we have both audio/video. With the projector system they now run, I have to take a PA and output the audio from the headphone jack and then run the S-video to the projector. I am hoping the new MBP will have one cable connection and she be on her way!

Well for starters, anyone who puts audio into a PPT presentation needs to be taken out back, beaten, drawn and quartered, beaten again, put in a stockade, flogged, then beaten one final time for good measure. The only audio coming from a presentation should be the presenter speaking. The PPT slides are meant to be secondary in nature, highlighting the major points of the presentation as you go along, not be the presentation. Audio and video, even those stupid transition effects, just distract from the content. The people at Microsoft responsible for putting those features into PowerPoint, and thus opening the floodgates for all their competitors, should have all the above happen to them, and then add being shot to the very end of it. It's still far too good a fate for the **** those people have loosed unto the world.
That being said, I'm under no illusion that this is going to do anything but get worse over time, so here's the deal.
You need a MDP to HDMI adapter that is designed to also carry the audio signal. But it couldn't hurt to teach her how to ensure that the audio output device is set properly. Just in case. Or, you could do the right thing, and start smacking the people who think it's cute to put all these animations and sound effects into presentations. There are a very select few times when that sort of thing is justified, and 99.99999999999999999999999999999% of the time when one is used, it's not one of those times. Then you wouldn't really have to worry about getting audio AND video. Might be rather cathartic too.

I just ran a software update for Java and MacBook Pro SMC, now my Mini Display Port to HDMI TV is not working. The TV is flickering. The Mac Display is fine.

I was just watching / streaming TV off Safari on my actual TV.
I'm using a Mini-Display Port to HDMI cable for the connection to the external display.
Software update popped-up and said there was an update for Java and for SMC.
I ran the update and upon the computer restarting, my external display (my TV) is no longer working. It is now flickering.
It won't work in Mirroring or set up as an extended display.
I've reset SMC / PRAM / Safe Mode / Even restored from a Time Machine backup (From before the updates were done).
What could it be?!

I keep saying this over and over, in the hope that people who do a search will find it. Apple cannot possibly test for or be reponsible for the bazillion combinations of adapter, cables, and TV's out there. The only monitors that are 100% guaranteed to work with the MacBook Pro are the Cinema Displays and Thunderbolt Displays, because, they're made by Apple. They're expensive, but they work perfectly.
My guess is that you bought a cheap MDP to HDMI cable, or have a defective one. From my reading of these boards over the past few months, cheap cables have a high failure rate. And the regular priced ones have only a slightly less of one. Try a new one. Make sure you do not damage the Thunderbolt port.

Do I need to download Mini Display Port to VGA update?

I want to be able to watch movies from the MBP on the TV. (Panasonic 32" about 5 years old). Air Play doesn't work through the ATV, the stream is erratic and unwatchable. Both HDMI ports are in use for other things. So I got a Mini Display Port to VGA adapter and a VGA cord and plugged it into the PC input on the TV. I get the screen to come up (no sound, is that normal?) so it seems to work.
Now I read that there is an update for the Mini Display Port to VGA. I downloaded it then was unable to open it because it said it was from an "unidentified source" (Apple!!!!) Do I need this? The article that described this was dated 2009, so I'm thinking it is way obsolete but I want to be sure.
And what about sound and VGA? Do I need a separate audio in connection, and if so, to what input since the PC input is VGA only.
I know that's a lot of stuff. Thanks.

Steve1000,
VGA only supplies video, so no sound is normal. You’ll need another connection to provide sound — perhaps through your audio out (headphones) port?
When you have the Mini DisplayPort to VGA adapter in use, run Software Update; if it doesn’t offer the adapter’s firmware update, then your adapter already has it installed.

What adaptor do I need to connect from mini display port to a dvi monitor

I want to connect a 2nd monitor to my mac mini via the mini display port, will the Apple adator do this ok or will I need an active adaptor

I had trouble with different Mini DisplayPort to DVI adapters, including a couple of Apple branded ones.
When I mentioned the problem to the Apple rep. at Fry's. He walked straight over to the rack, handed me a > Kanex Mini DisplayPort to DVI-D Adaper grined and said, I've never had one of these baby's come back.
After that my 2010 Mac Mini has been very stable running Dual 21.5" Samsung DVI monitors. One in on the Apple Supplied HDMI to DVI adapter, the other now on the Kanex Adapter has been rock solid for over a year.

Extender for Mini Display Port. Need help.
