Mini DisplayPort to VGA adapter not working under Vista (Boot Camp).

Thanks for the quick reply! In the meantime I have tried to block the EDID signal by blocking pin 12. But this didn't work for me!
A collegaue of mine with a slightly newer MacBook Pro is running XP, and for him everything was fine with the same projector.

Purchase new mid 2009 Mac Book Pro 17 = $2,450.00
Purchase Apple add-on's for new Mac Book Pro = $400.00
Add Vista 32 OS = $120.00
New Laptop bag = $100.00
Airline tickets to visit partners and prospects for new software launch = $3,500.00

Laptop VGA output not working for first large meeting with over 40 people, having to cancel rest of trips, looking like an idiot = PRICELESS

And yep, I am the CEO of the company. If they don't get it fixed (soon), it will be the first and last one we ever buy....

Hi all,

Just bought a new MacBook Pro 13" and encountered the same problem. Tried many things, in the end I changed my VGA cable to a shorter one and it worked like a charm.

Hope that helps,

Apple, you know those commercials where someone goes into Best Buy to purchase a new laptop and always leaves with a PC? Well guess what, here you have a bunch a people who went in and purchased an Apple and having a problem

Would someone at Apple PLEASE address this once and for all.

I have the same problem with a 2. display or beamer and the vga minidisplayport. My privat workarount is: first connect the beamer with mac osx choose the resolution then switch to vista and don´t touch anything. Sometimes it works. It works with a cable normal length but all pins. Apple, Microsoft and Nvidia had to resolve that problem as soon as possible. I need a reliable way for presentation.
All the other thinks are working fine with boot camp and vista 64. I am an old winman 😉 and a new macman 😟.

If this problem is specific to Vista and Win7, I'm thinking that the fix can be addressed in a driver update. While complaining to Apple might eventually get word to the nVidia driver developers, I believe the more direct path would be for all of us to submit feedback to the nVidia Driver Feedback page:

https://surveys.nvidia.com/index.jsp?pi=ad1c492c9d7488731f70e8d4356ba631

Please click the link above and help make this a high priority fix for nVidia's next driver release. Numbers count!

I have sumbited the information to Nvidia, but the fact remains that I spent over $2,500 on a machine that does not work from Apple. While it may in fact be Nvidia's "fault", I expect Apple to at least post some information or push Nvidia to get a fix out. I hate seeing so many people having issues, and Apple not even responding.....

POSSIBLE RESOLUTION?

Hey everyone, I just spent an hour troubleshooting this. And for the ppl that have gone through the demo crisis... been there. It wasn't the projector.

I have: March 2009 MacBook Pro running Windows 7 natively. Latest nVidia drivers for Win7.

Here is the story:

Came into work with my VGA adapter (I usually use DVI, but I left that one at home). I know the monitor works, capable of 1680x1080. (Co-worker beside me has same model, but who knows if internally they are truly the same. More on this later.) Plug in my adapter, 640x480 on external LCD, cannot change resolution, shows up as "UDI" display in Windows. Complete shutdown, restart. No joy.

Another co-worker has October 2008 MacBook Pro. He is running on a large Dell LCD in native resolution glory. I tried his adapter on my Win7. Same problem. Now tried HIS MBP running OSX. Getting weird resolutions on LCD, no 1680x1080. Reboot my MBP to OSX. EXACTLY the same results as his. Ok, at least we have some consistency now. (This is important b/c he told me the adapter/dongle has a firmware update, meaning his adapter and mine MAY not be the same.)

As I fiddled with my OSX settings, he tried plugging into my co-workers monitor. We noticed the cables look different... (!!)

Voila! He got native resolution on that system, with his OSX. I tried mine (still on OSX), with his working adapter (the one he just had). Works! I tried the other adapter. Still works!

Ok, time for the big test. Reboot into Windows 7... TADA! Native resolution glory!! Checked display properties, and Windows reports SyncMaster as the display, not some generic "UDI" junk. Sweetness.

Hope this helps someone out there, b/c I know this isn't the first time for me. Clearly the cable makes a difference. Therefore, once you find a cable that works, keep it with you... yet another piece I need to carry around with my MBP.

Good luck all!

...so is there any real solution yet besides shorter cables?

I haven't found one yet. Does anyone know some programers who could fix the driver issue? i would chip in!

cheers

I'm done waiting for Apple to fix this, not acceptable by any standard, so I voted with my wallet and returned my MBP. Back to the not very pretty, but functional, Lenovo T60 that is now running Windows 7 quite beautifully thank you.

So I too have a vga switch that forces the resolution down to 640x480 when connecting a projector. I found if I connected a shorter vga cable directly into the projector it worked at the higher resolutions.

Once the correct higher resolution is set in Windows 7 on the shorter cable, leaving the machine on I can unplug the short cable and replug in the longer cables going to the switch and it all works retaining the higher resolutions.

I just found this thread. How depressing. Add me to your list.

I also attempted a presentation with my new Unibody MBP and found the display frozen at 640 x 480; very embarrasing. So I spent over $1,000 more to have my 2 y/o MBP with regular DVI rebuilt, and I carry that just for presentations.

I will add that I have have pinged NVIDIA repeatedly on their forum about this. up till now, nothing other than an automated. response. Then a few days ago, out of the blue, I got a message from NVIDIA responding to a 2 month old post asking if my problem was with mini-DVI or miniDP. I had not realized till then that they were different.

Nothing more since from NVIDIA except a request to complete a customer satisfaction survey. A very bad idea for them.

I am glad to see at least one of us has successfully returned their MBP.

I have been one of the most strident run-Windows-on-a-Mac people for years. Spending this kind of money on an essentially useless machine, and finding zero support from the vendors, especially NVIDIA, has really rattled my confidence in Apple.

I had high hopes this would be fixed with Snow Leopard Boot Camp Drivers. Unfortunately, I am sad to say the bug persists... Very frustrating...

Hi,

That's unfortunate that Snow Leopard didn't have anything in it to help with this issue. I to was hoping that perhaps this would be addressed and I haven't gotten to update a system to Snow Leopard yet. Oh well still waiting.....

This issue also doesn't seem to be addressed in nVidia's 186.81 WHQL driver release (27-Aug-09).
