Mini display with vga adapter and vga multiplier

running into problems with the mbp using a mini display adapter to vga and a vga multiplier. no signal at the projector. is there any difference between a vga signal from a pc and a vga signal from apple's mini display adapter to vga? ie. bandwidth, resolution, etc.... would upgrading to a new os ('lion') help in this problem? many thanks

Hi Guys,
Checked the mini display with Dell flat monitor and Samsung LCD tv , works perfect. The VGA port of my old monitor is not in good condition.

Can I use a mini display port to VGA adapter and then a VGA to av adapter to connect my MacBook pro to my standard definition tv?

No. You need a converter box like this to go with your MDP-VGA adapter:

Connect two external monitors to mini DP(using a mini DP to VGA adapter) and the VGA out at once

I am trying to connect two external monitors to mini DP(using a mini DP to VGA adapter) and the VGA out at once. Windows recognize both monitors as well. But it dowsn't let me use all three monitors at once(see the below image). In the dropdown, it lists all three monitors. Problem is there are two active displays I can select.

The GPU(s) in your T400 (and most other laptop brands) will support two different displays concurrently. If you want to support more than two different displays concurrently, you will need another GPU external to the T400.
Generally, if you want to use two external displays on a T400 you will nee dto use a docking station.
I have read messages on various fora on this topic and know that there are a number of ways of doing this, but as I have never had a need to do this myself I can't tell you how to go about it.

I have a VGA adapter and an iPad2. Tried projecting my iPad2 to projector using the VGA but doesn't work. Tried it with friend's iPad1 and it works. Why??

Yup - nothing happens. I then took the same VGA cable and plugged it into my friend's iPad1 and it worked perfectly when she opened Keynote. My understanding is that the iPad2 mirrors the entire screen, so no need to go into any specific application in order to project to the screen, right? Do I need to download any specific app or change any settings in order to be able to project the screen using VGA?
Sorry - novice at this. Not very tech minded either...

Yeah, I'm having the same exact problem - It seems that the thunderbolt minidisplay port is only able to output the analog VGA signal, not the digital signal to support DVI and HDMI. This is a bug that came up after installing 10.7.1. I bought my macbook air with 10.7 on it, upgraded it to 10.7.1 as soon as I got it, so I have never been able to use hdmi or dvi with my macbook air. This is an extremely frustrating problem for me, I used HDMI on a daily basis with my PC. I have spent many hours at the genius bar running diagnostic tests so Apple can get as much information as possible to create a fix for this problem. I have been emailing tech support for 3 or so weeks now, they keep saying that they are working on a fix and it should be out soon, but 10.7.2 has come and gone and I still have no HDMI functionality with my MacBook Air!

Mini display port to dvi or vga adaptor?

I currently use a MacBook Pro and want to use the mini display port to my 24 inch Samsung LCD screen. My question is should I use the mini display port to DVI or VGA? My Monitor has both ports on back. I know that DVI is Digital and suppose to be the superior source compared to VGA analog, but I have only used VGA when using my Monitor with my old PC and it seemed fine enough for me.
If, I do go the DVI digital route will it be that much better graphics compared to just using VGA?
Finally, has anyone hooked up a mini display port to either DVI or VGA adaptor into an LCD monitor? What are your thoughts, concerns, advice etc. I realize its a very easy thing to do, but seem tied up between using DVI or VGA port.
Thanks,
DH

Diffferences are not remarkable but DVI is indeed better. I wuold then choose DVI.

Does a DVI to VGA adapter, and a DVI to DVI adapted do the same job?

A DVI to VGA adapter provides a conversion from DVI to VGA.
A DVI to DVI adapter, what is that? If the input is DVI and the output is DVI, what is the need for an adapter?
Tell us what you are trying to accomplish.

Apple Mini-DVI to Video Adapter and Mac mini (2009)

Can anyone tell me whether the Apple Mini-DVI to Video Adapter listed here:
http://store.apple.com/ca/product/M9319G/A
works with the latest Mac mini (early 2009)?
If it does not what other solutions are there to connect to composite, component or s-video?

KC from Ann Arbor, MI had this to say as a review on the page to which you have linked;
10-May-2009
I bought a Mac Mini (May 2009) and this Mini-DVI to Video adapter with plans to use it to send an S-video signal to an analog TV. Though the sales staff at the Apple store said it should work, it does not. The graphics card apparently should support it, and it may be addressed with a future driver update, but as of now this does not work. I have used a mini-DVI to VGA adapter and monitor to verify that the port is working, and also verified that the S-video cable and TV input work. There are third party VGA to S-video/RCA adapters available so I plan to use one of those for my purposes. This is probably a 5-star product when used with the right Mac; however, Apple should have made it clear that having a mini-DVI port on your Mac is necessary but not sufficient for this to work - hence the 3 stars.

Mini Display port DVI adapter not working on Thunderbolt Port

For some time I've been using a mini display port to DVI adapter on an slightly older MBP to connect to my HD TV. I recently purchased a MBP with a Thunderbolt port and when I try to connect it to my TV via my mini-display-port-DVI adapter things are not working properly. The MBP is seeing the Philips TV but it isn't listing all the display modes and I'm not able to send any video to it. Does the Thunderbolt port require a new display port to DVI adapter?

Let me be clearer; I've got the MDP-DVI adapter connected to a cable that is DVI on one end and HDMI on the other. I've got both laptops so I can compare side by side. I plug in the MDP-DVI adapter to the old laptop and all works well; I plug it into the new laptop and while the laptop does see the TV, the display modes for it are all 1080p which is wrong I don't see any desktop image on the TV unlike when I plug it into the older laptop. This is very disappointing as I expect things to just work with Apple products.

Mini Display to HDMI adapter causing screen to go white/ gray

I recently purchased a mini display to hdmi adapter to hook my macbook pro up to my samsung led tv.
At first it worked great but after a few mins of inactivity both screens would go white or light gray and the macbook was totally unresponsive.
I pressed buttons, moved the mouse and nothing….I had to hard shut off and then restart the macbook to get the screens to come back up. I thought it might have been just a glitch but then it happened 2 more times all within the span of 2-3 hours. (keep in mind this is the first time ive ever used this adapter and have had no prior issues with my macbook)
I have no idea what could cause this type of issue.
Any suggestions or ideas on what could cause this? is it my settings or my computer?
I looked up the manual for my macbook online and my settings match what it says they should be… Im at a loss.
Any suggestions would be greatly appreciated. Thank you.

* my connection is macbook pro - mini display to hdmi adapter - hdmi to hdmi cord - Samsung LED tv.

Best Mini Display to DVI adapter for 2011 17" MBP w/no blocked ports!

I am looking to get a Mini Display to DVI adapter for my 2011 17" MBP.
+(Preferably it would even be one with a 6' cord.)+
It is not clear which one I should buy. Apple's (adapter only, no cord), is $30, while I can see others for far less on Amazon.
I have read that some of these adapters actually block the FW800 and USB ports on either side.
A blocked, or displaced FW800 port is a deal breaker.
1. Can someone with a 2011 17" MBP tell me that they have either one of these adapters, or the one with the cord, and that it doesn't block their FW800 port? (I'll pay the $30 (albeit grudgingly) if its the only one that works.)
2. This may be a dumb question, but the specs on these adapters say that they are capable of 1080p resolution. Would that mean they would work with a 1920x1200 monitor?

You might want to try the "MBP Display" discussion threads, might be able to find what you are looking for in there or get better support there.
I don't think I can help very much, but I have the Apple's adapter (no cord) and it doesn't block my usage of FW.

The Best Mini Display Port HDMI Adapter?

I am looking for recommendations on a good Mini Display Port HDMI Adapter for my Macbook Pro 2011 Sandy Bridge. I have gone through about 4 adapters in the past year due to the adapters become unresponsive after 2 or 3 months. I use my Macbook heavily on external monitors for my work (averaging 7 hours or more a day between various monitors).
I can rule out the HDMI wire itself not being the cause of the problem but the adapters have been a huge miss and drain on cash this year. If anyone who is also a heavy user can point me in the direction of a durable adapter I would be very grateful.

I always recommend monopriice.com for cables and adapters.
Mini DisplayPort | Thunderbolt® to HDMI® Adapter w/ Audio Support
But all these adapters are in the form of "pigtails" and no matter where you get them the strain relief and the cables can fatigue and break from constant bending or pulling (doesn't help your macbook socket any either).
Maybe you should order a bunch. They are cheaper that way at monoprice.
Another possibility might be you trying a mini displayport to HDMI cable. No adapter.
Kanex Mini DisplayPort to HDMI Cable with Audio Support (10 ft.)
But of course you could get about 6 adapters for the price of that one cable!

Mini display to hdmi adapter problem

Hi,
When I connected my mini display to hdmi adapter to hdmi, and hdmi cable to my ASUS PA238QR monitor, my early 2011 MBP 13" detects the monitor, but the monitor shows "hdmi no signal".
I tried unplugging everything, including the adapter and hdmi, but to no avail. I tried putting my computer to sleep, and waking it up, still, nothing seemed to be the cause of the problem.
I read through some old discussion on this issue, and nobody seems to have a solid solution besides purchasing another adapter.
I tried booting into win7 and still, the monitor shows "hdmi no signal".
I am 100% sure my monitor and hdmi works becuase when I used other laptops it's fine.
Thus, I'm suspecting it's the mini display to hdmi adapter's problem.
Is there a way I can make sure that my macbook pro is outputting the signal?
Any recommendation or advises are welcomed. Thanks for reading.

If you've an HDMI port on your television, you could always try that.
I've used this adapter from Monoprice successfully - not bad for under $7.
Give your TV a try - if no go, then you'll know that it's an adapter problem.
Good luck,
Clinton

Mini DisplayPort to DVI Adapter and macbook pro

I have a 2010 macbook pro 13", samsung 20" LED display connected via mini display port. The setup has been fine for a few months but occasionally both displays would turn blue as it tries to detect itself(I assume) when this happened I would just need to reset to fix itself. This week I used my laptop away from the screen for a while, once I connected it to the display the blue screen has become more prominent, it would blank out for no reason intermittently and has become progressively worse. I've tried shutting down, cleaning the mini-display-port, resetting PRAM and now I'm out of ideas.
Could it be related to the new EFI firmware update v2.5? that was the last major update installed.

You might be better off taking the computer and the display into a Apple Genius Bar annd showing them what is happening.
They may have a fix or maybe something needs to be replaced.
