In June of 2008, Hp introduced a new computer display, the HP LP2480zx - also known as the DreamColor display.
The HP DreamColor LP2480zx Professional Display is the world’s only color-critical LCD based on HP DreamColor Engine technology. This uniquely affordable monitor delivers broad color support, rich visual quality, and consistent results.1
The HP DreamColor LP2480zx Display, a color-critical display, was developed through a first-of-its-kind technology collaboration between HP and DreamWorks Animation SKG. The 24-inch diagonal HP DreamColor liquid crystal display (LCD) provides a range of more than 1 billion colors in a 30-bit, LED-backlit widescreen display, says the company.
This display has a gamut that exceeds the primaries for Adobe RGB and normally meets the Digital Cinema P3 gamut. Technically, it is labeled with P3 emulation. The display has a radically different numeric pipeline. It has a complete matrix shaper look up table capability. The display can accept dual link multi-byte 10 bit image data and the pipeline works to 12 bits. The LCD module has a true 10 bit interface. This means that full 10 bit data is being passed to the display module which is very unusual. The LUTS are 12 bit deep. The matrix multiplier allows the display to change color spaces instantly. The display has an LED backlight and that is used to control luminance and white point. This display has been designed to work at lower luminances. It can be adjusted from 45 to 250 NITS. This lower range is needed in the Motion Picture Market. The Contrast Ratio is 1000:1 or greater.
The display is aimed primarily in the video and motion picture market place, where they have a number of color space standards based upon media and content delivery. The "shift on the fly" color space emulation is very suited to color evaluation in these markets.
For the photographic and graphic arts community, the display's gamut and it's ability to handle greyscale ramps without banding artifacts should be appreciated. It is a radical departure from typical high-end displays and it hits a price point that is well below most of the professional displays in the video and motion picture market.
The most notable feature of this display is its ability to produce a larger gamut of colors than most of the displays in its class.
- The RED outline represents the sRGB space.
- The GREEN outline represents a typical LCD display.
- The MAGENTA outline represents the AdobeRGB color space.
- The BLUE outline represents the HP Dreamcolor Display
The LED Backlight unit of the LG LM240WU5 Panel, that the HP Dreamcolor is based on, does not have an active unformity compensation. Thus any mechanical and/or panel inconsistancies cannot be corrected by the backlight.
Dreamcolor APS software
The HP DreamColor Advanced Profiling Solution software can only be used with the HP DreamColor colorimeter. (Manufacturer Part Number: KZ300AA) It is an i1Display 2, but with optimized filters for the DreamColor monitor. The licensing is contained in the hardware, so the software will only work with a DreamColor colorimeter, not with any other hardware. Xrite says they have no plans for making the ColorMunki or the i1Pro compatible with the HP APS software. DDC control with this monitor is not compatible with the ColorMunki or the i1Pro.
This display can be profiled with ProfileMaker, i1Match, etc. like any other LCD display, but you will miss out on the advantages of the HP Dreamcolor DDC controls, which are really quite nice. (Xrite)
You can profile an additional monitor with the HP DreamColor APS software, but the software functions are limited, much like the ColorMunki (by Xrite). You can control contrast, brightness and adjust for the ambient light conditions in the room, but you cannot set a specific luminance level or gamma.
