Using the HP DreamColor LP2480zx
Monitor for Professional Video
Applications
Introduction
While the original target market for the HP DreamColor LP2480zx Professional Display was color-
critical 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 video post-production
environments. 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 LP2480zx which make it an attractive choice for these applications
include:
 The monitor is capable of accepting a video signals with a wide range of frame and field rates
(including 29.97/59.94, 25/50, 24 and 23.976
frame-rate conversion (FRC). This means that you can work at standard video rates and not see the
tearing, frame skipping, judder, or other motion artifacts that are usually seen when video is
displayed on an LCD monitor.
 A very broad "native" color gamut, plus built-in color gamut remapping capabilities which enable
the monitor to accurately match all common color-space standards currently in use within the
professional video community. Factory-calibrated "color space presets" are provided covering the
ITU-R BT.709 and ITU-R BT.601 (SMPTE 145/SMPTE-C) standards, and a DCI-P3 Emulation preset
provides 98% coverage for that color space. In addition, 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 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.
 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, while maintaining minimal neutral axis color drift. In other
words, the grays stay gray.
 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.
In order to best utilize the HP DreamColor LP2480zx monitor in as a video display device, it is helpful
to understand how the monitor receives, processes, and outputs a video signal. The following pages
discuss these topics in detail and provide you with recommendations and configurations for the
monitor.

The LCD panel has the ability to sync at rates down to 47.952 Hz. These frame rates will be displayed at a doubled rate of 59.94, 50, 48, and
43.952 Hz respectively. This exact doubling will not introduce any frame-rate conversion artifacts.

  • Page 1 Using the HP DreamColor LP2480zx Monitor for Professional Video Applications Introduction While the original target market for the HP DreamColor LP2480zx Professional Display was color- critical 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 video post-production environments.
  • Page 2 Input The HP DreamColor LP2480zx offers a wide range of video inputs, including all popular PC/workstation interfaces and “consumer video” connections. The available inputs are:  2 – DVI-I (supporting both analog and digital signals)  1 – HDMI (version 1.3) ...
  • Page 3: Video Black Level

     The monitor is fed an analog signal via the composite, component or S-Video inputs. These signals must be converted to an RGB progressive signal and input via one of the digital inputs, such as HDMI. When a video source that meets one or more of the above criteria is sent directly to the LP2480zx, a warning will be displayed onscreen and the color space presets will be disabled in the On Screen Display (OSD) menu indicating that they cannot be selected.
  • Page 4 and blanking . Though these are not required for digital video, when ITU-R BT.601 – which codified the digital versions of the NTSC and PAL video formats – was created the standard was designed to allow for the capture of a portion of these signals. For example, blacker-than-black was preserved as many video engineers considered it critical to capture the rise time out of blanking and into the active picture when converting an analog signal to digital.
  • Page 5 PLUGE pattern When the monitor’s black level is properly calibrated, the darkest bar (which is blacker than black) should no longer be visible; but the lightest bar (which is slightly brighter than video black) should still be visible. (The middle bar is video black.) As long as the bar on the right is still visible it is considered that the monitor is within the acceptable range for calibration.
  • Page 6 Configuring the Gefen Converter As noted earlier, the HP DreamColor LP2480zx is capable of very closely matching the appearance of standard studio reference monitors, including the CRT-based products which are still common in the industry. But in order to achieve this performance level the video signal must be fed through a signal converter so that what reaches the monitor is an RGB progressive signal.

If you are using a 16:9 aspect ratio use the 1080p/59.94 output format. 576p/50 or The LP2480zx assumes a 4x3 aspect ratio for 1080p/50 standard definition signals.
