Planar's SD2220 features innovative StereoMirror™ technology, which provides high-quality HD 1080 (1920 x 1080) 3D stereoscopic images and produces comfortable extended viewing ergonomics for multiple users. Flicker-free operation allows extended use with without stereo fatigue. Planar's SD monitors are addressed using several existing stereo modes in Windows, DirectX or OpenGL applications and with a number of commercially available graphics cards. Left eye/right eye information is presented to the correct monitor directly via a DVI interface with no user-supplied hardware or processing. Using the output from the appropriate graphics card, the Planar SD line of monitors includes all the hardware you need to view stereo.
