It appears that I have suffered the curse of Nvidia again, this time on my brand new work unibody Macbook Pro 13in. Under Windows Vista and 7 the Nvidia Geforce 9400M graphics card can only send a 640×480 resolution signal to projectors through the official Apple Mini DisplayPort to VGA adaptor.
It appears that I am not the only one, there is a large thread that is continuing on the Apple Discussions forum. There are a bunch of other people reporting the same issue, but Nvidia doesn’t have a solution yet. In fact, they have flat out said there are a huge list of unsupported (and will NEVER be supported) features. The following are from page 16 of the 190.62 Nvidia drivers release notes:
The following are features and functionality that were available in driver releases
supporting Windows XP, but are not–and will not be–available in driver releases for
Windows 7:
• High resolution scaling desktop (HRSD)
• MultiView Display Mode (for NVIDIA Quadro NVS graphics cards)
• NVKeystone
• Unified back buffer (UBB) controls
• OpenGL Video Overlays – This is an operating system limitation.
• Overclocking – GPU overclocking is no longer supported in the default GPU driver control panel. This feature is available in the NVIDIA System Tools software, which you can download from NVIDIA.com.
• GPU Temperature Monitoring – Temperature monitoring is no longer supported in the default GPU driver control panel. This feature is available in the NVIDIA System Tools software, which you can download from NVIDIA.com.
• AGP Settings Adjustment

• nView Horizontal and Vertical Span Modes – Due to architectural changes in the new Windows Vista Window Display Driver Model (WDDM), span mode cannot be supported in NVIDIA graphics drivers. NVIDIA recommends using the built‐in Windows Vista multi‐display modes.

• DVD/MPEG Extensions (such as was provided with Windows Media Center Edition)
• Audio Extensions (such as was provided with Windows Media Center Edition)
