Digital Video - July 2008 - (Page 24) FIRST LOOK HP DREAMCOLOR LP2480zx DISPLAY personal printers and commercial printing presses. The latest product in the DreamColor line is the HP LP2480zx display, a 24"-diagonal widescreen with a max resolution of 1920x1200. The LCD panel boasts 30-bit color accuracy (10bits on the red, green and blue channels), allowing for approximately 1 billion color combinations — more than 64 times the amount available on mainstream LCDs — and circumventing any banding artifacts generally found in 24-bit displays. Inside, the HP DreamColor Engine supports multiple color space emulation presets, including full gamut, Rec. 709 (high-definition), sRGB, Rec. 601 (YUV 4:2:2), Adobe RGB and DCI-P3 emulation (also known as Digital Cinema). DreamWorks and HP admit that their P3 profile is “almost there,” but not yet perfect. There is also a slot for a user-defined color space. The emulation of these spaces without loss of 8-bit dynamic range is achieved through a combination of color space remapping by the HP DreamColor Engine, 10-bit drivers on the LCD panel and white point control via the LED backlight unit. Another interesting physical attribute includes a night-vision user interface with on-screen button tags and auto-fade backlit bezel buttons for easy control under bright and dark working conditions. All of the LP2480zx display parameters can be adjusted via display-control interfaces (USB and DDC/CI interfaces and MCCS command-set), enabling the use of standard- or custom-color calibration software. An optional Advanced Profiling Solution kit is available for calibrating and profiling the display and for validating and optimizing ICC profiles. The kit contains a colorimeter and related software for both Microsoft Windows and Apple Mac OS X that provides a number of options for display calibration (white point, gamma and luminance). Linux support is planned through an open source project. The APS will also validate the viewing environment’s ambient lighting conditions.

BY IAIN STASUKEVICH hen the digital artists at DreamWorks Animation in Glendale, California, needed a display system that would guarantee perfect color fidelity across literally hundreds of PC workstations, they turned to longtime technology partner HewlettPackard for a solution. The movie studio and the computer manufacturer have been working together for years to develop new technologies to enhance and streamline the creative process. The result of the companies’ combined effort was the DreamColor display system. The once-proprietary DreamColor system has now been expanded and reworked into a line of off-the-shelf hardware and software products. Packed with 24 dv july 2008 W industry-standard specs for media, ink and toner properties with respect to color gamut and dynamic range, HP’s goal is to achieve consistent color appearance across a wide range of display and printing technologies. Assuming that one is working with the same applications and within the same color space, all DreamColor devices are designed to provide reliable, repeatable color reproduction from one operation to the next. In short, all projects executed within the DreamColor pipeline come with a WYSIWYG guarantee. The basic idea is that DreamColor will drive multiple user platforms. Initial product releases employing HP DreamColor technologies primarily have been relegated to the output side of production, i.e. http://www.dv.com
