Introduction
While the original target market for the HP DreamColor LP2480zx Professional Display was colorcritical PC and workstation customers, especially those involved in computer graphics at the
professional level, this product is also very well-suited to use in professional broadcast studio,
television production, and similar “video-centric” applications. The HP DreamColor LP2480zx can
provide a level of performance very comparable to—and in some cases, exceeding—that of current
“studio reference” monitors of any display technology, and at a very competitive price.
Features of the HP DreamColor LP2480xz which make it an attractive choice for these applications
include:
A very broad “native” color gamut, plus built-in color gamut remapping capabilities which enable
to monitor to provide highly accurate matches to all common color-space standards currently in use
within the professional video community. Factory-calibrated “color space presets” are provided
covering the ITU-R Rec. 709 and Rec. 601 (“SMPTE-C” primaries) standards, and the monitor may
be calibrated by the user (via the optional Advanced Profiling Solution calibration tool) to match
other standard gamuts.
The RGB LED backlight permits both precise setting of the monitor “white point” (without affecting
the video data being provided to the LCD panel), and gives the monitor a very wide range of white
luminance adjustment; white may be set anywhere from a minimum of 50 cd/m2, for use in dark
viewing environments, up to a 250 cd/m2 level suited to standard office lighting (these values
assume the standard D65 white point; maximum and minimum levels may be slightly different for
other white point settings).
The tone response (“gamma curve”) of the HP DreamColor LP2480zx may also be very accurately
calibrated to duplicate the specified response of various output device standards, and/or match
that of CRT-based reference monitors, with no significant difference across the three primary
channels and so no significant color error in the product’s grayscale (neutral-axis) response.
The LCD panel used in this monitor provides a very wide viewing angle with minimal off-axis color
shift, and a static contrast ratio of 1000:1 (typ.). Coupled with the wide range of backlight and
response curve adjustability, this permits the HP DreamColor LP2480zx to very closely duplicate the
performance of traditional CRT-based studio reference monitors under a wide range of viewing
conditions.
The monitor is capable of accepting standard 59.94/60, 50, and 48 frames/fields per second
input video with no frame-rate conversion (FRC) performed internally, and so no motion artifacts
resulting from a FRC appear in the final displayed image.
Application usage
There are, though, several specific points regarding the use of the HP DreamColor LP2480zx in these
applications of which you should be aware:
Inputs
The HP DreamColor LP2480zx offers a wide range of video inputs, including all popular
PC/workstation interfaces and several “consumer TV” connections. These include two DVI-I inputs
(with both analog and digital video supported), one HDMI 1.3, one DisplayPort, and one each of
S-video (standard DIN connector), composite video (an “RCA” style jack) and component video (three
“RCA” jacks).
For professional video applications, it is strongly recommended that one of the digital video inputs
(DVI, DisplayPort, or HDMI) be used. Analog “PC” or “VGA-standard” video may also be used, via
the analog sections of the DVI-I inputs (an adaptor cable will be needed to connect to non-DVI
sources). Use of the S-video, composite, and component inputs is not recommended, as these inputs
