Product Introduction
Introduction
The WN-5220-S VideoWall is a multi-frequency, multi-source display capable
of displaying a wide range of video sources. The clear, bright image is a
product of careful engineering and optical innovation. Setup is easy because of
light weight and simple mechanical connections. And it is fast because there
are only a few adjustments necessary to configure the image.
The optional Ultra-Thin Mullion screen gives the display additional flexibility in
meeting the most demanding image quality applications. By eliminating the
front-surface frame, this screen nearly eliminates the visible seam between the
displays. (Mullion: the metal edge around the screen.)
Clarity’s Big Picture™ option is a built-in data/videowall processor. Without the
need for an external processor, Big Picture can scale the source video to
accommodate any display wall size up to four high and four wide.
Features
Clarity’s products are designed and developed by experts in LCD projection
technology and offer significant advantages over conventional cathode ray
tube (CRT) based systems including:
• optical resolution of 800x600 pixels
• ability to scale lower resolution sources up to 800x600
• supports a wide variety of computer and video formats
• superior image quality (even in high ambient light conditions)
• substantially lighter weight – 120 lbs (55 kg)
• significantly reduced depth (reduced footprint)
• lack of image flicker
• improved brightness uniformity (no “hot spots”)
• no convergence requirements
• no color drifting
• easy to service
• fast and easy setup

Additional Features
• direct compatibility with a wide range of video and computer data
sources: 800x600 and 640x480 for PC and MAC; 31.5 kHz line
doubled RGBS video
• with the optional S/300 electronics, 15.75 kHz RGBS video and the
ability to decode and display NTSC, PAL and SECAM directly
Options and Accessories
Clarity’s display products can be enhanced with several accessories.
!"
Ultra-Thin Mullion Screen – The options are:
• The standard screen has a mullion 1/8” (3 mm) wide.
The mullion is a strip of sheet metal surrounding the
screen which holds it in place.
• The Ultra-Thin Mullion Screen, or mullionless screen,
does not have the 1/8” (3 mm) strip of sheet metal
around the screen. The edge of the screen goes to
within 0.025” (0.64 mm) of the edge of the display unit,
which makes the lines between display units almost
invisible in the finished video wall.
!"
S/300 Option - Video Input Module
This option adds the ability to scale up the image on each
edge of the display for a better image fit when working with
multiple displays. It also adds three new source inputs:
15.75 kHz RGBS video, and composite and S-video in
both NTSC, PAL and SECAM.
!"
Clarity’s Big Picture™
This option allows a single video source to be expanded
over a video wall up to 4x4 displays, eliminating the need
for an external processor. (All display units in the video
wall must have this option.) Scaling and moving of the
individual images facilitates exact matching at the borders.
!"
SRT-100 Screen Removal Tool
This tool makes it easy to remove the normal mullion
screens when the displays are used in video walls, where
units are placed directly adjacent to each other. The
SRT-100 minimizes the chance of damaging the screen
and the screen’s latches. (It cannot be used with Ultra-Thin
Mullion Screens.)
!"
SAT-500 Screen Alignment Tool
This tool is essential to properly position the display units
with the Ultra-Thin Mullion Screen in a video wall. It helps
assure the correct spacing between adjacent screens in
the assembled video wall. (Cannot be used with standard
mullion screens.)
