Marshall Electronics warranties to the first consumer that this V-R842DP-DVI LCD monitor will, under normal use, be free
from defects in workmanship and materials, when received in its original container, for a period of one year from the
purchase date. This warranty is extended to the first consumer only, and proof of purchase is necessary to honor the
warranty. If there is no proof of purchase provided with a warranty claim, Marshall Electronics reserves the right not to
honor the warranty set forth above. Therefore, labor and parts may be charged to the consumer. This warranty does not
apply to the product exterior or cosmetics. Misuse, abnormal handling, alterations or modifications in design or
construction void this warranty. It is considered normal for a minimal amount of pixels, not to exceed three, to fail on the
periphery of the display active viewing area. Marshall Electronics reserves the option to refuse service for display pixel
failure if deemed unobtrusive to effective use of the monitor by our technicians. No sales personnel of the seller or any
other person is authorized to make any warranties other than those described above, or to extend the duration of any
warranties on behalf of Marshall Electronics, beyond the time period described above. Due to constant effort to improve

Product Overview
The V-R842DP-DVI is a dual screen high definition LCD monitor set featuring our completely digital TFT-MegaPixel™
active matrix LCD platform. Utilizing 8.4-inch panels with 2.4 million pixels each, the V-R842DP-DVI provides the
highest pixel density available while occupying only 4RU. Our proprietary digital signal processing features 10-bit A/D
conversion of all analog signals, with 4X over-sampling and 5-line super-adaptive 2D comb filtering of composite
signals. Emulation of SMPTE-C/EBU color and adjustable color temperature enable the most precise color
representation possible. De-interlacing is performed using our HyperProcess algorithm with motion adaptive
interpolation. Multi-format compatibility accommodates virtually all video formats including NTSC/PAL, 480i/p, 720p,
and 1080i standards. VGA and DVI inputs accept VESA standards allowing the display to be used as a computer
monitor. Advanced features include aspect ratio settings, a variety of screen markers, underscan mode, blue-only
mode, monochrome mode, H/V delay, and Pixel-to-Pixel mode.
Features
■
■
■
High-Resolution Dual 8.4” Panels
The V-R841DP-DVI features an all-digital TFT-MegaPixel™ active matrix LCD system with 2.4 million pixels. Each
LCD panel features a brightness of 400 cd/m2, 400:1 contrast ratio, and a 170° all-around viewing angle making the
display ideal in a variety of environments and lighting conditions.
Multi-Format Compatibility
With analog and digital inputs, the V-R842DP-DVI accommodates many video formats. Input types include VGA and
DVI with HDCP. Accepted formats include 480i/p, 576i/p, 720p, and 1080i standards, as well as VESA PC formats
through SXGA (1280 x 1024).
Maintenance
End-to-End Digital Signal Processing
Analog signals are digitized using an advanced 10-bit process with 4x over-sampling, 5-line super-adaptive 2D comb
filtering, and exacting color space conversion. Video is scaled to fit on the screen in the highest possible resolution
using a state-of-the-art LSI that incorporates precision gamma correction and our HyperProcess motion adaptive
interpolation for interlaced images.
■
Screen Cleaning
Periodically clean the screen surface using ammonia-free cleaning wipes (Marshall Part No. V-HWP-K). A clean micro-
fiber cloth can also be used using only non-abrasive and ammonia-free cleaning agents. Do not use paper towels.
Paper towel fibers are coarse and may scratch the surface of the polycarbonate faceplate or leave streaks on the
surface. Antistatic and fingerprint resistant cleaning agents are recommended. Do not apply excessive pressure to the
screen to avoid damaging the LCD.
■
■
ColorMatch Conversion with Color Temperature Adjustment
Emulation of SMPTE-C/EBU color space allows the V-R842DP-DVI to replace any broadcast CRT monitor. Settings
include D55, D65 and D95. Bias and Gain adjustment for each color enables precise color matching and white
balance.
■
Faceplate Dusting
Advanced Features
Dust the unit with a soft, damp cloth or chamois. Dry or abrasive cloths may cause electrostatic charge on the surface,
attracting dust particles. Neutralize static electricity effects by using the recommended cleaning and polishing practice.
Aspect ratio settings, underscan mode, blue-only mode, monochrome mode, and H/V delay are a few of the advanced
features making the V-R842DP-DVI at home in any broadcast environment. Pixel-to-Pixel mode also allows native
display of any incoming image format. Underscan and H/V delay are available only when monitoring standard-
definition formats.
■
■
Flexible Screen Markers
A variety of screen markers in both 4:3 and 16:9 modes allow accurate monitoring of the different aspect ratios used in
broadcast environments.
User-Definable Function Buttons
Two user-assignable function buttons allow quick access to numerous settings and features including aspect ratio,
screen markers, monochrome mode, color temperature, delay mode, and more.

As the V-R842DP-DVI monitor has a native resolution of 1024 x 768 RGB pixels, incoming images are automatically
scaled to fit the screen:
•
•
In 4:3 mode, images are scaled up or down to fill the entire 4:3 screen (1024 x 768).
In 16:9 mode, images are scaled to fill the maximum 16:9 portion of the screen (1024 x 576), with black bars filling
the remainder of the screen.

supplying at least 3.5 Amps at 12 Volts.
Each tally light is activated via the HD-15 connector by
connecting the corresponding pin to ground. A variety of
external devices can be used to perform the contact
closure. No additional power should be supplied to the
HD-15 port.
Note: The aspect ratio setting is ignored when Pixel-to-Pixel mode is enabled.
