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

Just wanted to say that I no longer have problems with output to a projector using the newest bootcamp upgrade in windows 7.

I previously had to use a short VGA cable. Problem is now fixed.

I tried just about everything I've found on the web and I've decided I'm just going to start from scratch. It'll be a pain, but I think my best bet is to wipe the current partition and start over. I don't have a lot of software installed in Windows, so that minimizes the pain a little. IF a clean install does not work, though, I will be royally annoyed.

Did a complete clean install and it solved all the issues. I used Boot Camp assistant to wipe out the windows partition and started from scratch (using Boot Camp 3.0 that came with Snow Leopard). I then did the 3.1 update. I then downloaded the latest nvidia driver AFTER doing the boot camp update. Everything works fine (so far). I just find it hard to believe that, for the sake of ONE video driver, I had to do a complete re-installation as I kept losing windows functions (no more system restore points, would not even do a regular backup, quality of onscreen graphics was atrocious).

I have windows7 on bootcamp snow leopard, and had no vga output to external monitor. Went to the apple store and "Jim" gave me the solution. Bring up bootcamp, then insert the apple install disc and reinstall bootcamp. That seemed to fix everything. All my windows programs were OK - did not need any reinstalls, and installed drivers fixed the vga output to external display. You gotta love these guys. They are good. I really need this function because next week I start teaching and the software only works on windows, not on snow leopard.

So based on the recent posts I upgraded to Boot Camp 3.0 using the Snow Leopard disk and used Apple Software update to upgrade to Boot Camp 3.1. (I don't believe you can get to 3.1 except through 3.0.) I don't have easy access to a projector, so I have not confirmed that I can get VGA to an external display with anything other than the default resolution.

If you can confirm found that this is the solution, please post!

So far with one test the new drivers work with an external projector. I'm running Boot Camp 3.1 with the Apple drivers. Previously my unibody MBP has NEVER worked properly with an external projector over miniDisplayPort to VGA, so this is very good news.

The NVidia control panel setup for multiple displays appears to be different.

*Finally solved the external display resolution problem.*

Just purchased a new Core 2 Duo, MacBook Pro, 15.4'' display with the NVIDIA GeForce 9600M GT video card. Loaded Windows7 32-bit with BootCamp 3.0 and then upgraded the Windows NVIDIA video driver with the latest NVIDIA driver (version 196.75) from www.laptopvideo2go.com. Side note: Before updating the NVIDIA driver, I also loaded all of the laptop drivers in Windows with the MacBook recovery disk and completed all Windows updates. I then ran into the same resolution disply problem everyone here is having, which is why I ended up here...

Solution:
1) Update BootCamp from 3.0 to 3.1 ( http://www.apple.com/downloads/macosx/apple/).

2) Uninstall NVIDIA 196.75 driver and the accompanying NVIDIA software bundle.

3) Install NVIDIA 195.81 driver bundle with the modified INF file - downloaded from www.laptopvideo2go.com.

4) Display works perfectly and tested the solution on 3 difference projectors.


Hopefully, you can just skip step #2 and install the 195.81 driver from the get go after the Bootcamp 3.1 upgrade. It appears that after you upgrade to BootCamp 3.1, you will need to uninstall your current NVIDIA driver and reinstall. I could not get the NVIDIA 196.75 driver to work properly, which is why I went with an older version. There are a couple of versions between the two, but I haven't checked to see if any of them work. Good luck with that.

If you install Microsoft Update via Windows Update, then this will offer a WHQL version of 196.21 for Geforce 9600m GT. To install this one in german language I only had to delete one exe. ATM I can't check which one. I use my MBPu 17 offen in presentation tasks and all works as expected.

What was the setting in Norton? As I'm getting the same script errors.
