4 Introduction Introduction The uniformity in image representation is a vital element in creating a video wall that consists of multiple displays. However, due to factors like component variation and aging, it is inevitable for each display to produce images with slight differences in color and luminance even when related settings are identical among all displays. The Color Management is designed to minimize such differences and enhance the image uniformity of all displays in a video wall application. It works by first measuring and comparing the color characteristics of each display, and then calibrating all displays with a common and optimal setting. With the Color Management, you can also adjust color settings of each display easily on a host computer, or backup and restore calibration data quickly. Key features The Color Management provides the following functions and features: • Supported calibration targets: - Color temperature (6500K/9300K/11000K) - Gamma (1.8/2.0/2.2/2.4) - Brightness (backlight luminance) Refer to page 5 for more information about the calibration targets. • Supported display tiling matrix: 1x1~10x10 • Supported display parameter: 10 bits LUT (Look Up Table) for R/G/B • Supported internal test pattern: 256 R/G/B/W levels • Accuracy: Delta_x, Delta_y < 0.5% with (1) DVI source for 30%~80% white level and (2) I1D3 measurement • Colorimeter that displays the color meter measurement values • Local backup and restore functions that makes it easy to save and restore LUT and R/G/ B gain settings • Manual adjustment functions (brightness, contrast, R/G/B gain and offset) that allow fine-tuning of individual display System requirements The following items are required to use the Color Management. • A color meter (supported model: X-Rite i1 Display Pro) • A host computer (PC) that meets the following minimum hardware and software requirements: CPU Pentium 1GHz Free memory 1 GB Hard disk space 400 MB Operating system Windows XP (32-bit/64-bit), Windows Server 2003, Windows Vista (32-bit/64-bit) or Windows 7 (32-bit/64-bit) RS-232 port An available RS-232 port HDMI/DVI/VGA port An available HDMI, DVI or VGA output port • HDMI, DVI or VGA cable and RS-232 cable The firmware version of the PH and PL series displays must be V1.06 or higher to work with the Color Management.
