Introduction

Following the longstanding tradition of providing the finest custom theater products,
Runco proudly unveils its 70-inch Crystal Series™ LCD, the CX-70DHD. Runco’s largest
LCD flat panel joins the esteemed Crystal Series, which represents the finest Runco has to
offer and is a testament to Runco’s commitment to deliver the most exquisite flat-panel
displays for an unsurpassed large-screen experience. Combining image prowess,
impeccable design, flawless function and incredible craftsmanship, the Crystal Series
products bespeak unparalleled luxury for the elite few who covet them.

The Runco CX-70DHD is a native “Full-HD” (1920 x 1080) LCD that is ideal for rooms of
distinction where a large screen size is desired, but where ambient light makes front
projection difficult and the glare of a plasma screen simply unacceptable. In addition to its
exceptional contrast ratio and superb gray scaling for true-to-life image quality, the
CX-70DHD features the ISF™ (Imaging Science Foundation) calibration suite, including
day and night modes for an optimal picture in the most challenging lighting conditions.

Designed exclusively for discriminating tastes, the CX-70DHD is the first LCD flat panel to
feature Runco’s proprietary external DHD™ video controller/scaler/processor. The DHD
not only incorporates Runco’s exclusive advanced Vivix III™ digital video processing
technology to achieve the highest level of image fidelity, but it also enhances
standard-definition digital and NTSC content to near high-definition quality.

Regardless of video source, Runco’s CX-70DHD provides rich, detailed HD imagery.
While lesser displays may show signs of image distortion, especially at larger screen sizes,
the CX-70DHD incorporates Runco’s WideVision™ technology with exclusive
VirtualWide™ content conversion, which masterfully converts all 4:3 content to
widescreen 16:9 aspect ratio and optimizes Anamorphic and Letterbox content with no
loss of image integrity.

The CX-70DHD offers exceptional installation flexibility. It measures less than six inches
thin for unobtrusive installation on a wall, and the external DHD processor allows for a
pristine installation, with just a single HDMI with HDCP output to the display required. All
source and component inputs (Composite, S-Video, HDMI with HDCP, and RGB) are
handled by Runco’s DHD, which, like all of the components, can be hidden from view.

Figure 3-2. Ventilation Requirements for Enclosure Mounting

Due to its extraordinarily high level of video processing performance, the DHD Controller
may distribute video signals with a perceptible level of audio latency. In order to easily
solve this issue, Runco recommends using the DHD Controller with a high-quality audio
receiver that has the ability to effectively synchronize audio and video signals.

Most mainstream audio receiver/switchers have the ability to synchronize the audio and
video to the Advanced Television Systems Committee (ATSC) prescribed tolerances.
According to the ATSC, the sound program should never lead the video program by more
than 15 milliseconds, and should never lag behind the video program by more than 45
milliseconds.

compensated for during the installation.

Other Considerations Here are some other considerations and tips that can help improve your installation, avoid

damage and prolong operating life:

• Keep the ambient temperature constant and below 35°C (95°F). Keep the display away
from heating and/or air conditioning vents. Changes in temperature may cause drifts in
the display circuitry, which may affect performance.

• Keep the CX-70DHD away from devices that radiate electromagnetic energy such as
motors and transformers. Common sources of these include slide projectors,
speakers, power amplifiers and elevators.

• Handle the unit carefully when installing or carrying it. Use the built-in handles; DO NOT

PRE

touch or hold the screen face.

• Set the unit away from heat, excessive dust, and direct sunlight.

• Protect the inside of the unit from liquids and small metal objects. In case of accident,
unplug the power cord and have it serviced by an authorized Service Center.

• Do not hit or scratch the panel surface as this causes flaws on the surface of the
screen.

• For correct installation and mounting it is strongly recommended to use a trained,
authorized dealer.

• To avoid sulfurization, it is strongly recommended not to place the unit in a dressing
room in a public bath or hot spring bath.

Installation

You can install the CX-70DHD either on a table or other flat surface (using the included
table stand) or on a wall using the optional wall-mounting kit.

Before installing the wall mount or
table stand, place the panel face
down on a soft, flat surface. Place the
protective sheet, which was wrapped
around the panel when it was
packaged, between the screen and
your work surface to avoid scratching
or otherwise damaging the screen
surface.

Picture Use the controls in the Picture Menu to calibrate your CX-70DHD for optimum picture

quality.

The CX-70DHD has been designed to incorporate setup and calibration standards
established by the Imaging Science Foundation (ISF). The ISF has developed carefully
crafted, industry-recognized standards for optimal video performance and has
implemented a training program for technicians and installers to use these standards to
obtain optimal picture quality from Runco video display devices. Accordingly, Runco
recommends that setup and calibration be performed by an ISF certified installation
technician.

All signal types require separate processing. Therefore, you need to calibrate each DHD
Controller input separately.

Although it may be possible to obtain satisfactory picture quality using the naked eye and
regular program material, Runco recommends using an external test pattern source
(Ovation Multimedia, Digital Video Essentials or AVIA test DVD or equivalent) for best
results.

Connect your test pattern source to the input that you are calibrating and proceed as
follows. Perform the adjustments in the order listed here.

acronym for “Picture Line-Up Generation Equipment.”)

Some television programs are produced based on the assumption that older television
sets may not display the outer edges of the broadcast picture area. Overscan effectively
trims away these inactive, outer edges and enlarges the remaining portion of the image to
fill the display area.

For HDTV, DVDs and other video sources, Overscan is generally not necessary or
desirable.

This control defines the amount of overscan applied to the image. The range is from
0

to 20. There are two overscan modes:

•In Crop mode, each increment adds a mask at the top, bottom, left and right edges of
the source image equal to 0.5% of the displayed horizontal resolution (1% total). A
setting of 10, for example, crops the image 5% on all sides or 10% total.

•In Zoom mode, each increment adds a factor to the scaling of the source image so
that the vertical and horizontal resolutions are 100% plus 1% increments of the size
determined by the aspect ratio function. A setting of 10, for example, zooms in on the
image 5% on all sides or 10% total.

Figure 4-6 illustrates the effect of each overscan mode setting.

For best results, use a good test pattern such as a smooth gray consisting of a clear
pattern of black and white pixels, or a similar “half on, half off” graphic image. Adjust the
slidebar until the image stabilizes and each pixel is clearly defined. You may notice that
you can stabilize the image at more than one point. Use either setting in such cases.

Tracking (RGB, Component or SCART sources): Tracking determines the frequency
of the pixel sampling clock, indicated by the number of incoming pixels per line, so that all
pixels generated by a particular source are sampled.

Steady flickering or several soft vertical stripes or bands across the entire image indicates
poor pixel tracking. Proper pixel tracking helps ensure that the image quality is consistent
across the screen, that aspect ratio is maintained and that pixel phase (see above) can be
optimized.

Display Color: Use the Display Color settings to adjust the color balance at the DHD
Controller output. These settings are saved independently for each input and display
mode.

•Gain: Use the Gain controls to correct color imbalances in the bright areas of the
image. A good way to do this is to use a test pattern consisting mostly of solid white
areas, such as an 80 IRE “window” pattern. If the white areas contain traces of red (Pr),
green (Y) or blue (Pr), decrease the Gain for that color.

•Offset: Use the Offset controls to correct color imbalances in the dark areas of the
image. A good way to do this is to use a test pattern consisting mostly of dark gray
areas, such as a 30 IRE “window” pattern. If the gray areas contain traces of red (Pr),
green (Y) or blue (Pr), decrease the Offset for that color.

Used correctly, the Gamma control can improve contrast while maintaining good
details for blacks and whites. If excess ambient light washes out the image and it
becomes difficult or impossible to see details in dark areas, lower the gamma setting to
compensate. This improves contrast while maintaining good details for blacks.
Conversely, if the image is washed out and unnatural, with excessive detail in black
areas, increase the setting.

• Color Temp: Select Color Temp from the Display Color menu to adjust the color
temperature. Color temperature establishes the “color of gray” by adjusting the 75%
white point to various color points.

What are “color points?” A “color point” is an x/y coordinate pair that defines a
color’s location on the standard CIE chromaticity graph, shown in

The Input Image settings establish the “zero point” for the Picture
menu settings, whose values represent offsets from the Input
Image settings. For example, if you set Brightness to 10 in this

actual setting value of 20 (10+10).

Input Color: The Input Color controls are similar to those in the Display Color menu (see

independently for each input and display mode.

•Gain/Offset (HD1, HD2 and Component/SCART inputs only): These controls
operate similarly to those in the
the Y, Pb and Pr signal components rather than the red, green and blue channels.

• Chroma Delay: use the Chroma Delay control to correct a mis-aligned image from a
Composite or S-Video source. Chroma delay in an image causes color shifts to occur
to the left of the vertical edge transitions, producing artificial shadows or a “halo” effect.
If necessary, adjust this setting to eliminate them.

•Noise Filter: To apply noise filtering to the input signal, select Noise Filter from the
Input Color menu. The Noise Filter is useful for clearing up noisy images from 480i

Color Space: Select Color Space from the Service menu to choose the color space of
the source signal for HDMI, RGB, and component connections.

• The default setting, Auto, functions as follows:

• HDMI: If the Auxiliary Video Information (AVI) infoframe contains color space and/or

range data, the CX-70DHD uses that information. Otherwise, for RGB sources, the
CX-70DHD uses the RGB-Video color space. For component SDTV and EDTV
resolutions, REC601 is used. For other component video resolutions, REC709 is
used.

• RGB: If Hsync or Vsync signals are present, the CX-70DHD uses the RGB-PC color

space. Otherwise, REC601 is used for SDTV and EDTV sources, and REC709 for
all other sources.

• Component: For SDTV and EDTV resolutions, the CX-70DHD uses the REC601

color space. For all other resolutions, REC709 is used.

In most cases, the Auto setting determines the correct color space to use. If it does not,
you can force the CX-70DHD to use a specific color space. Choose one of the following:

• REC709 sets the color space matrix to that defined in ITU-R BT.709.

• REC601 sets the color space matrix to that defined in ITU-R BT.601.

• RGB-PC uses RGB color space and sets black at 0,0,0 RGB and white at
255,255,255 RGB, assuming an 8-bit image.

• RGB-Video uses RGB color space and sets black at 16,16,16 RGB and white at
235,235,235, assuming an 8-bit image, to correspond to the luminance values defined
in digital component standards.

6. External Control

Note

In addition to using the DHD Controller front-panel keypad or remote control unit, there
are two methods of controlling the CX-70DHD and DHD Controller externally:

• Using a serial (RS-232) link to send ASCII commands and receive responses to those
commands.

• Using discrete infrared (IR) codes to program a third-party remote control unit.

The following sections describe both of these methods.

Y

The DHD Controller uses a simple text-based control protocol to take requests from
control devices and to provide responses to such devices. This section describes how to
send control messages over a serial link between the DHD Controller and an
automation/control system or a PC running terminal emulation software.

6.1 Serial Communications

To interface the CX-70DHD with an automation/control system or a PC running terminal
emulation software, connect it to the Display Control output of the DHD Controller as
shown in
input of the DHD Controller as shown in Figure 3-11.

Configure the RS-232 controller or PC serial port as follows: no parity, eight (8) data bits,
one (1) stop bit and no flow control. Set the baud rate to 19200, to match that of the DHD
Controller RS-232 port.

Using Discrete IR Codes

IR Command Protocol The IR control codes have the following characteristics:

The DHD Controller accepts commands in the form of IR signals that conform to the
Phillips RC5 protocol. Each DHD Controller remote control button has an RC5 control
code associated with it.

You can use these codes to program a third-party, “universal” remote control unit to work
with the DHD Controller. These third-party products usually come with a computer
software application for this purpose. For more information, consult the documentation
provided with the remote control unit.

• Each code consists of 14 bits:

• Two (2) start bits (always 1);

•A toggle bit. This bit is inverted every time a key is released and pressed again. This
allows the DHD Controller to distinguish between a button that remains down or is
pressed repeatedly.

• Five (5) address bits. The default address is 17 (binary 10001). To change it, select
Remote Control from the Service menu and follow the steps given on page 52.

• Six (6) data bits.

• The carrier frequency is 36 kHz, with the modulated pulses having a 25% duty cycle.

• Commands are sent at a maximum rate of 9 Hz.

For example, here is the RC5 control code for the ON button on the DHD Controller
remote control unit (assuming the default address is used):
