Dell 2400MP projector and mini-DisplayPort

I have a MacBook Pro with a mini-DisplayPort and wanted to know which mini-DisplayPort to VGA adapter should I get to connect to the Dell 2400MP? It only has a VGA port, and I'm doing a presentation at a place that uses such a projector, and wanted to be prepared in case no one there knows how to use the PC and bring my own laptop. I see the mileage on these adapters may vary, so which one works best?

Get the Apple adapter. It costs more, but it's made better than most.

What's the difference between thunderbolt and mini displayport?

I'm trying to connect my Macbook with a monitor and I'm thinking of what cable to get. I will have to connect using a (Thunderbolt to HDMI cable) or a (mini displayport to HDMI cable).
I was wondering what's the difference between Thunderbolt and mini displayport
Thanks

@bontistic: it is not true that only the Macbook Air supports Thunderbolt. All models(!) support thunderbolt: also the Macbook Pro's and Mini's. Eg.: http://www.apple.com/nl/macbookpro/features.html#thunderbolt
My Macbook Pro from 2011 already supported Thunderbolt...

MBP Unibody and Mini DisplayPort to S-video adapter

Why is the Mini DisplayPort-to-s-Video Adapter the only adapter that Apple can't seem to make? My late model PowerBook G4 came with its own S-Video out, which was perfect for running video to the dual overhead projectors in my Sunday School class. But alas, the PowerBook couldn't keep up with the multimedia video requirements I made for it, so I upgraded to the MacBook Pro (mid 2009). But I can't find a friggin' adapter to save my life! I've tried an external VGA unit, only to have the video rolls all over the screen with no way to stop it. All I need is one simple adapter: a Mini DisplayPort to S-Video /Composite adapter. Apple makes almost the exact same adapter, but it's for the mini-DVI out. At least the PowerBook had a full-size DVI out- all the MBP has is the single, stupid Mini DisplayPort. Why can't the fine folks at Apple make up their stupid minds which ports they're going to use?

This is why I think that won't work. I might be wrong tho.
Once you head on over to VGA from the Mini DisplayPort, you are then talking about an ANALOG signal. This analog signal must be changed BACK to digital in order to work with S video. So, what you need is a VGA to S video converter box. They are a lil too pricey for me, around $100 I think.
What I was thinking was this. Since Mini DisplayPort and S video are both digital signals, you need to have digital all the way. I wonder if the Apple Mini DisplayPort to DVI Adapter shown here:
http://store.apple.com/us/product/MB570Z/A
would work when connected to the DVI to Video Adapter shown here:
http://store.apple.com/us/product/M9267G/A?fnode=MTY1NDA3Ng&mco=MTA4NDU1Mjc
At that point you would need an S video cable connected to the second adapter...but if the first adapter is in fact transmitting a digital signal, the second adapter should then just pass through that digital signal to the S video cable.
Has anyone tried this?

X1 connectivity problem with old VGA beam projector using mini displayport to VGA adaptor.

Hi all,
I would like to ask you how to connect this X1 with VGA projector as well.
actually, X1 has a external interface specification as mini displayport 1.1a.
So I bought mini displayport to VGA adapter from MAC store.
(Actually, Lenovo Korea office doesn’t sell this adapter directly on Korea, even in the future.)
and try to connect both of LED monitor and beam projector.
LED monitor was worked as well. but, this adaptor doesn't work with VGA projector. TT
Please help me how to work this adaptor with projector as well.
Solved!
Go to Solution.

Hi everybody. I was having the same issue here, but I bought a Mac minidisplayport to VGA adapter. It worked on my Monitor but it was not working on my clients VGA beam projectors. But today I figured out a way to make it work, and it is pretty easy; just change your laptop screen resolution.
When you connect the mini Dport to VGA adapter to the projector VGA receiver cable, just change your laptop screen resolution to 1024x768 (maximum) and the projector will receive the signal with no problem.
This is the best solution that I found, because is easy to find a Mac/Apple Mini display Port to VGA adapter.
Hope this works for you too.
Regards,
J.

Mini DVI and Mini DisplayPort are not the same thing!

I bought this "Mini DVI to DVI" adapter thinking it would hook up my Epson projector to the new MacBook Pro:
http://store.apple.com/us/product/M9321G/B?fnode=MTY1NDA3Ng&mco=MjE0NTE2OA
BUT tonight I found out it is NOT the right thing. The adapter I need would be "Mini DisplayPort to DVI (or VGA)"
I found the full sized DVI ♂ and ♀ ends of the adapter and projector cord I do have don't "mate" right either. The pins have a slightly different arrangement!
I just want to warn anyone who might stumble in the same place. I'm off to my local Apple Store to return the adapter for one that will fit one of my projector inputs with a Mini DisplayPort plug on the other end.

Good call!! Thanks a million. Glad I asked & thanks for the quick response. I was getting frustrated. Thanks again!!!!!

External monitor loses signal to macbook pro through DVI cable and Mini DisplayPort Adapter

Hello,
So I had my external monitor connected to my MBP with a DVI cable and a Mini DisplayPort Adapter, for a while already. But sometimes, the monitor would lose signal from the laptop and gives me a white noise screen. Now, the monitor can't receive signal at all, even after I got a new Mini Displayport Adapter. When the monitor and the MBP is connected by the cable and the adapter, the monitor would say "no signal" and the MBP screen would flicker (I think it's trying to connect to the monitor, but can't). The new Mini Display Port Adapter also makes the screen flicker, so I'm not sure if it's the problem is at the adapter or the DVI cable. I'm pretty sure it's not the monitor.
What do you think? Have you ever have a screen flickering problem when your MBP is connected to an external monitor?

I have had the same problem. By following your suggestions I got to arrangements. I could not send them off to the side. When I hit the mirro disply key everyting worked. I got it solved by clicking in arrangements and setting displays to mirror display.
I am still have a problem of no sound coming through my tv.

HT3131 how do i get audio from my HDTV when using a hdmi cable and mini displayport??

How do I get audio to display from my HDTV when I'm using a hmdi cable and a mini-displayport adapter on a macbook late 2008??

The Mini DisplayPort to HDMI doesn't carry audio unless you have the Mid 2010 model 7,1 and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI.
With the Late 2008 model 5,1 Aluminum Unibody there is an adapter that uses the Mini DisplayPort and a USB port to combine video and audio to HDMI. It's only 2 channel stereo not 5.1 Dolby Surround.

Daisy-chaining Thunderbolt and Mini DisplayPort

I have a 13-inch MacBook Pro (Early 2011), i7. In the future, would it be possible to daisy-chain a Thunderbolt-compatible product like the Echo Express (http://bit.ly/pTlDFr) with a monitor that only has DisplayPort, HDMI, and DVI (http://amzn.to/nohGbj) using a Mini DisplayPort to DisplayPort/HDMI/DVI adapter, or does the display have to support Thunderbolt as well? Thank you.

Audio and Mini DisplayPort on Late 2009 iMac (27")

I have a Late 2009 27" iMac and a 42" HDTV that I would love to hook up with eachother so I can start using Plex-and-the-likes on the bigger screen.
But I'm wondering if the Mini DisplayPort of this iMac supports audio, as I do not want my sound to come from the other side of the room when watching stuff on the TV.
I've been reading around on the net, but I can't seem to find anything conclusive that tells me that it works (some discussions and thread claim that it should work, but some official documentation regarding the Late 2009 and Mid 2010 iMacs (http://support.apple.com/kb/ht3913) only mentions the Mid 2010 one with audio output in the Mini DisplayPort
Not sure if it matters, but I'm running a fully up-to-date OS X Lion.
Thanks in advance.

According to http://support.apple.com/kb/HT4241, your late 2009 iMac's displayport should support hdmi audio output, (but I have no idea whether there might be OS-X version limitations).
Here are two attractive alternatives to the spendy apple-referenced adapters. I can't vouch for them, but they have great user reviews, and very low-risk pricing. (I just ordered one of each to try with my MBP and new HDTV -- but neither the adapters nor the TV have been delivered yet.)
miniDP-to-hdmi adapter from monoprice.com @ $6.65
miniDP-to-hdmi cable from amazon.com @ $8.67
Another interesting thought would be to skip the miniDP entirely and go with USB-to-hdmi, with an adapter that sounds almost too good to be true. Any comments on this technology (displaylink) would be much appreciated:

What is the difference between Mini DVI to VGA adapter and Mini DisplayPort to VGA Adapter?

My macbook is MacBook4,1. early 2008

The port itself is shaped different.....
.....here is a link to read through on the technical differences of the 2 ports....
http://en.wikipedia.org/wiki/Mini_DisplayPort
......your MacBook has the Mini-DVI port........the VGA end of the adapter is the same on both...

What's the difference between Mini DisplayPort and Mini DVI?

I've got a two month old unibody MBP. I want to connect it to my TV with an HDMI cable and therefore I need an adapter cable.
I've searched online and found Mini DVI to HMDI cables and they have the same symbol on them as the port on my mac, but the specs for my mac call the port a Mini DisplayPort.
Is Mini DVI and Mini DisplayPort the same thing?

The icon that appears beside the port indicates "video out", not any particular kind of port that can be used for that purpose. Apple has used at least six different ports to provide video out on notebook Macs in the last several years: S-Video, VGA, mini-VGA, DVI (and dual-link DVI), mini-DVI, and mini-Displayport. I believe the same icon appears beside all of them, but the ports and plugs don't look alike.

Mini DisplayPort to VGA Adaptor not Mirroring

13-inch MacBook Pro (Mid 2012) running 10.8.3
Monoprice Mini DisplayPort to VGA Adaptors freeze the system (no issues with Monoprice Mini DisplayPort to DVI connected to monitor) so I tried an Apple Mini DisplayPort to VGA Adaptor and that works ok, EXCEPT it doesnt automatically mirror to projectors like older models I have used.
Is the 13-inch MacBook Pro (Mid 2012) supposed to auto mirror when connected to projectors using Mini DisplayPort to VGA Adaptor?
Thanks for any assistance.

I havent had a chance to test, yet it looks like if I create the settings for mirroring when the projector is attached to the laptop, the setting should stick moving forward.. I thought it just auto-sensed. Will try and report back here if there are any changes or to solve the ticket...

Does Mini Displayport to DVI adapter support analog VGA signal?

I'm just about to buy a macbook pro. Since the MDP (mini displayport) to DVI and MDP to VGA adapters are £20 a pop, I can only afford to get one. Obviously DVI is better in general, but VGA supports more older hardware, CRTs, and the spare VGA input on one of my displays (where the desktop uses the DVI).
What I'd like to know is does the MDP to DVI adapter also support the analog VGA signal on certain pins (like most physical desktop DVI ports do)? If it does, since I have about 3 or 4 DVI to VGA adapters lying around, I can get the MDP to DVI adapter and use the DVI to VGA adapters with it if necessary, but if it doesn't I might be better off getting the MDP to VGA...

No. Unlike DVI, which in the DVI-I configuration has both digital and analog pinouts, DisplayPort (and mini-DisplayPort) are purely digital. Mini-DP to DVI then DVI to VGA will not work. If you look carefully at the Apple Mini-DisplayPort to DVI adapter, you'll notice it's a DVI-D connector - digital pins only.
The Apple mini-DisplayPort to VGA adapter contains a digital-to-analog converter.
So, you'll have to choose. If you want VGA, get Apple's mini-DisplayPort to VGA adapter.

Does Mini DisplayPort to VGA adapter support DDC/CI?

I have a Mac Pro and a MacBook5,1.
Mac Pro is attached to a BenQ monitor which supports DDC/CI communication.
With a capable software I'm able to set brightness and contrast of the monitor without using monitor's OSD (thanks to DDC/CI communication).
If I attach the same monitor to my MacBook5,1 with VGA cable through a Mini DisplayPort to VGA adapter, DDC/CI stops working.
I'm no more able to set brightness and contrast and the app reports that monitor isn't DDC/CI capable.
I'm sure its not an issue related to the app that I'm using to set brightness and contrast. It detects correctly both of the monitor (the internal and the external one) and I'm sure that I'm sending DDC/CI commands to the external monitor and not to the internal one.
So, does Mini DisplayPort to VGA adapter support DDC/CI, and therefore passthrough its signal?
Or is it a problem of MacBook and its Mini DisplayPort which does not support DDC/CI at all? I don't think so.
I hope you can help me.
Regards
Andrea

Using both MDP and Mini DVI on 2009 Mini

Can anyone confirm that you can use both video ports to mirror on the 2009 mini? Or is it an either/or situation?

No-one can confirm it until there is an actual 2009 model mini to test. However, all the evidence so far indicates the new mini will support two displays.
The page at http://www.apple.com/macmini/features.html includes:
There’s nothing quite like seeing your photos and movies on a big, beautiful display. Unless, of course, you add a second. Mac mini comes with both mini-DVI and Mini DisplayPort output ports, so you can connect up to two displays....
