About VirtualForge

The VirtualForge pattern generator software runs on any Mac OS X or Windows workstation that, in addition to its standard graphics output adapter, also controls a video output device (i.e. AJA Video Systems or Blackmagic Design) to drive a TV video monitor (e.g. LCD/LED, OLED, plasma, projector, etc.).


The VirtualForge software is controlled by Calman to produce bit-accurate test patterns at any required triplet value, through the video output device to the video monitor, for accurate grayscale, CMS, or 3D LUT video display calibration. This allows a video monitor that is being driven through a video output adapter to be conveniently calibrated with Calman.

VirtualForge also provides specialty test patterns for visual display performance testing or for optimizing the adjustment of display Picture controls.
