Description, Features
and Benefits
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.
The CX-70DHD includes a discrete remote, RS-232 interface and three, +12 VDC triggers
for greater integration capabilities that can help create the ideal entertainment
environment with touch-of-a-button convenience. The display’s elegant black bezel
matches any room décor.
Key Features and BenefitsThe CX-70DHD offers these key features and benefits:
• 16:9 Native Resolution: 1920 x 1080
• Multiple Aspect Ratios with VirtualWide™ Mode
• Includes DHD with HDMI video controller/processor
• Less than 6 inches thin
• Exceptional detail and artifact-free video enhancement
• ViVix™ video processing with 3:2 film detection circuitry
