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.
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.
