DHD Controller Description
Projector
DHD Controller
ANALOG INPUTS:
• Composite Video Input
Composite video is the most common type of signal used, but is also the lowest in
picture quality. Many sources have outputs that are limited to composite video, such
as some VCR’s and camcorders; others such as Laser Disc players actually produce
slightly better results when using composite video.
• S-Video Input
S-video is a better type of signal that can be used, but is MUCH better than composite
video. Using such sources as Satellite receivers, high-quality VCRs and DVD players
(with no component output) will produce a MUCH cleaner and sharper signal.
• Component Input
Component video is the best analog signal that can be used. The most common
sources that use component outputs are DVD players, and it is highly recommended
that component be used when possible. Component video goes one step beyond
S-video in picture quality; chroma (color) information is more resolved and the overall
picture appears more well-defined. (This Component input is for SDTV (480i/576i)
signals only)
• HD1 / HD2
These are High Definition Analog inputs to connect the outputs of high definition
sources such as HD tuners and set top boxes, HD satellite receivers, etc. These inputs
will accept and automatically detect signals as RGB, RGBHV or Component Video
(YPrPb).
DIGITAL INPUTS:
• DVI 1 / DVI 2
These are High Definition Digital inputs. Runco recommends using these digital inputs
whenever possible. Using the DVI 1 and DVI 2 inputs ensures the highest video quality
because the signal is carried in the digital domain throughout the entire signal path,
from the source, through the DHD and finally into the projector. This maintains maximum
signal purity.
Use these inputs to connect Digital High Definition sources that have a DVI output,
such as HD tuners and set top boxes, satellite receivers, DVD players, etc. You may also
connect computers with a DVI output as well, but accepted VESA standard resolutions
are limited to VGA, SVGA, XGA and SXGA at 60Hz refresh.

ISF CALIBRATION:
The DHD system 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.
The ISF Calibration section of the DHD Controller is reserved for Certified ISF Technicians
only. Please contact Runco Technical Support for information on ISF Calibration.
DHD Controller Description
16

Overall Functional Description
The DHD system consists of the VX-40d, VX-50d, VX-60d, VX-80d projectors
and DHD Controller. This system is unique in the way it is controlled; the
control center for this system is located within the DHD Controller. The DHD
Controller tells the Projector to turn on or off, controls its brightness, contrast,
color temperature and more. All of this is accomplished by Runco's unique
ComLink, which is the transfer of information between the DHD Controller and
the Projector via their ComLink ports using a CAT5 cable (or similar). Therefore,
only the DHD Controller's remote control is necessary to control all aspects of
this system; though advanced calibration can be performed at the projector
during initial installation (refer to the projector’s manual for details).
Besides being the system's control center, the DHD Controller is also a high-
quality scaler, which outputs all signals in the native resolution of the VX
Projector. The Composite, S-Video and Standard Definition Component signals
are sent through the DHD Controller's 10-bit decoder, de-interlaced, then scaled
to the native resolution of the Projector. In the case of HDTV or progressive DVD
signals, these are input to the RGB/Component port and bypass the DHD’s de-
interlacing circuitry.
In the next chapter, the menu system will be described in detail. There are many
adjustments available to perfect the DHD's image, including typical 'front-panel
controls' as well as color temperature and other image-quality controls.

When the MENU button is pressed on either the remote control or the front panel, the
main menu will appear on-screen. An example of the main menu is shown above.
Main Menu
Using the ▲ and ▼ arrow buttons, select the desired item
and press enter.
Input Source
The active source is indicated by an arrow next to the
source, note that in the example to the right, Composite is
the current source.
To select a source via the main menu, press either the up
or down buttons on the remote or front panel and highlight
the desired source, and press ENTER. Otherwise, you may
select a source by pressing either the left or right arrow
buttons (on the remote or front panel) when no menus are
on-screen, or by pressing one of the direct access buttons
on the remote control (recommended).
NOTE: If DVI input is used with HDCP content, RGBHV
output is automatically disabled This is in compliance with
HDCP regulations.
If pass-through is selected, note that no on-screen menus will be displayed since the
signal is simply being 'looped' directly to the output. When pass-through is the selected
source, pressing MENU will not automatically select the last selected input before Pass-
through was selected.

Aspect Ratio
Aspect Ratio provides selection of one of four aspect ratios:
Anamorphic, Standard 4:3, Letterbox or VirtualWide. To
select an aspect ratio via the main menu, press either
the up and down buttons on the remote or front panel,
highlight ASPECT RATIO and press ENTER. The aspect
ratio menu will then appear with the four choices; highlight
the desired aspect ratio with the up or down buttons and
press ENTER. Otherwise, you may select an aspect ratio
by pressing either the up or down arrow buttons (on the
remote or front panel) when no menus are on-screen, or
by pressing one of the direct access buttons on the remote
control.
NOTE: The Cinema (2:35:1) aspect ratio is only available with projectors equipped with
the CineWide lens option.
Picture
Picture quality adjustments are the controls that change
different parameters of the image such as the amount of
color, black level, etc. While these adjustments can be set
to suit the needs of the user, there is a way to set these
properly. This section will describe what each function
does and how to adjust them properly.
To access the picture quality adjustments, press MENU,
press the down button to select Picture (indicated by the
green highlight) and press ENTER. The picture quality sub-
menu will then appear.
To make an adjustment to a particular function, highlight the function with the up or
down arrow buttons and press ENTER. Once the function is on-screen (i.e. brightness),
pressing the UP arrow button on the remote or front panel will increase the value of that
function; pressing the DOWN arrow on the remote or front panel will decrease the value
of that function.
NOTE: A BLUE FILTER must be used so only the blue color bars can be seen on a
standard color bar test pattern. Blue filters are provided with the Video Essentials or
AVIA test DVDs.
While each of the picture quality adjustments can be set to suit the needs of the user,
there is a 'proper' way to set the adjustments. For setting TINT and COLOR, please
refer to the color bar test pattern below.
Tint
Tint (also known as 'hue') is essentially the ratio of red to green in the color
portion of the image. If TINT is decreased, the image will appear redder, and
increasing it will cause the image to appear greener. To set TINT properly, look
at the color bar pattern through a blue filter (or mute the red and green outputs).
Adjust TINT until the middle two tall color bars match the middle short color bars
(see color bar drawing).

Color
Color (also known as 'saturation') increases or decreases the amount of color in the
image. To set COLOR properly, look at the color bar pattern through a blue filter (or mute
the red and green outputs). Adjust COLOR until the outer two tall color bars match the
outer short color bars (see color bar drawing).
Brightness
Brightness adjusts the black level of the image. To adjust this properly, adjust Brightness
until the 'below black' bar just disappears, but the 'above black' bar is still barely visible.
NOTE: Some DVD players cannot pass the 'blacker than black' bar (they won't pass
PLUGE), and that bar will never be visible. In a case like this, adjust the 'above black' bar
until it is slightly brighter than the background that surrounds it.
Contrast
Contrast adjusts the white level of the image. For Fixed-pixel displays, adjust contrast until
there is a distinct definition between the two brightest bars.
NOTE: For best results, Runco recommends that CONTRAST be set to '0' or very close
to it. (see below)
