In Win7 & Windows Vista, rotation is performed by the Operating System directly and is supported by all NVIDIA Graphics Solutions. It is important to note that NVRotate is an WinXP only feature, where the rotation is handled by the NVIDIA GPU. NVRotate works with any display, allowing users to design custom applications and deployment with NVIDIA GPUs. The result is increased productivity as users can select the most optimal way to view their applications. Now, with NVRotate, you can rotate any display 90, 180 or 270 degrees for maximum flexibility. Many LCD flat panels support rotate (or pivot) mode natively within their monitor stand, but lack the software to provide full hardware acceleration for 2D and 3D applications, and video playback.
The display adapter is Intel G45/G43 chipset. NVIDIA®'s NVRotate™ -bundled with all NVIDIA WinXP Drivers for desktop, workstation, platform, and mobile solutions-allows users to pivot any display connected to an NVIDIA GPU from landscape to portrait mode, for easier information and application viewing.
