CalMAN Setup Guide

Thank you for purchasing the SpectraCal VirtualForge pattern generator software for Mac OS X or

Windows. The VirtualForge software runs on any Mac or Windows workstation that, in addition to its standard graphics output adapter, 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.

Mac OSX Requirements:

 Macintosh® OS X 10.8.1 or later

 Intel Core® Duo processor

 2 GB RAM

 2 GB available disk space

 Either PCIe or Thunderbolt™ support

Windows Requirements:

 Windows® Vista™ or later with latest OS updates installed (recommended: Windows 7® or later)

 2 GHz processor (recommended: 2 GHz Dual Core Processor)

 2 GB RAM

 2 GB available disk space

 Either PCIe or Thunderbolt™ support

Note: Windows running under VMware Fusion is unable to access Thunderbolt ports.

 The video output characteristics of each video output device controlled by VirtualForge are

determined by the individual device and by its associated control app. Use the control app to select device output signal options, including output resolution and frame rate.

 VirtualForge does not support NTSC (480i) on Blackmagic video output devices.

 VirtualForge supports Blackmagic HDMI outputs for sourcing calibration signals only with

Blackmagic Desktop Video version 10.8, or newer.

 VirtualForge support for Blackmagic SDI outputs, for sourcing calibration signals, is limited to the

Blackmagic default YCbCr 4:2:2 10-bit pixel format, which the Blackmagic control app does not provide the option of changing.

 AJA Video Systems reports that some Mac computers cannot connect to the T-Tap in Windows

running in Boot Camp.
