HP LP2480zx - DreamColor - 24" LCD Monitor Using Manual 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)
 1 – DisplayPort (version 1.1)
 1 – YP P component analog (using three "RCA" style jacks).
B R
 1 – composite analog (using an "RCA" style jack)
 1 – S-video (using a standard DIN connector)
Note: An analog VGA connection may also be used, via a VGA-to-DVI-I adapter cable (included with
the monitor).
For professional video applications, it is strongly recommended that one of the digital video inputs
(HDMI, DVI, or DisplayPort) be used. All digital inputs support 8-bits per pixel inputs and the HDMI
and DisplayPort additionally support 10-bits per color.
Use of the S-video, composite, and component connections is not recommended, as these formats do
not support RGB nor progressive signals and will therefore bypass the color-management features of
the monitor. This is described in detail in the next section.
While the HP DreamColor LP2480zx does not directly support the SDI/HD-SDI serial digital interface
commonly used for interconnects in professional post and broadcast facilities, there are a number of
products available which will cross-convert these signals into an HDMI, DisplayPort or DVI signal,
permitting them to be fed into the LP2480zx. For the best performance we recommend using an HDMI
or DisplayPort converter as those interfaces support the widest range of video frame rates and offer
the highest bit-depth, resulting in smoother color gradients.
HP recommends the following product for this purpose:
 Gefen, Inc. HD-SDI to HDMI Scaler Box (SKU: EXT-HDSDI-2-HDMIS)
This device supports Dual-Link HD-SDI connectivity and can perform YC
conversions. Note that proper configuration of this box is required or an incorrect video image will
result. We will discuss configuring the Gefen converter at the end of this white paper.
Color Gamut Remapping
As noted earlier, the HP DreamColor LP2480zx provides built-in color gamut remapping functionality,
which permits it to accurately emulate a wide range of standard output devices and color spaces,
including accurately matching specified RGB primaries, white point, gamma, and so on. This process
involves the mathematical conversion of input video data so that it is accurately mapped into the
monitor's very wide "native" color gamut.
However, due to the architecture of the "front end" electronics used in the HP DreamColor LP2480zx,
the color gamut remapping circuitry will be bypassed if the following conditions exist:
 The monitor is fed a YC
converted to RGB.
 The monitor is fed an interlaced or 1080-line progressive segmented frame (PsF) formatted signal
(for example, 1080PsF/23.976). These signals must be converted to true progressive signals via a
converter box.
