iRotate
iRotate provides convenient access to the native rotation capabilities present in contemporary display drivers, via a popup menu accessible from the system tray and optional system-wide hotkeys. It’s no longer necessary to resort to bloated Windows hacks, additional software layers or phantom drivers to achieve content rotation. In most instances, support is now available directly from the graphics chip manufacturers, who continuously improve and apply quality assurance to their drivers.
By leveraging the native rotation capabilities now provided by ATI, nVidia, Intel, Matrox, S3, XGI and others, iRotate offers exceptional speed and efficiency, with minimal impact on scarce system resources - the entire iRotate package, including installation, documentation, and native language support in all the major European and Asian languages, weighs in at only 125kb. And like all EnTech graphics utilities, iRotate supports multiple graphics cards from various vendors, simultaneously, under every multi-monitor enabled operating system from Windows 98 to Vista.
