contrast ratio and a jaw-dropping 300-inch

events, commercial installations,
auditoriums, conference halls and
any environment where standard
projector brightness simply
falls short.

professional-grade connectivity
including Dual HDMI, Dual USB,
AV, Audio Out and a LAN port —
making it the most capable
high-brightness projector
available online in India today.

20,000 Lumens — Extreme Brightness
for Any Environment

The RD-839’s 20,000 lumens output
places it in an entirely different
category from consumer projectors.
To put this in perspective:

At 20,000 lumens the RD-839 delivers
clear, bright and vivid projection in:

• Fully lit auditoriums
  and conference halls —
  no dimming required
• Outdoor daytime events —
  visible even in bright
  sunlit environments
• Large wedding and
  event venues —
  bright enough for
  300-inch screens
• Shopping mall and
  retail installations —
  attention-grabbing
  large format display
• Sports bars and
  entertainment venues —
  multiple large screen
  setups with a single unit
• Churches, temples
  and community halls —
  bright projection for
  large congregations
• Classrooms and
  lecture theatres —
  visible from the
  back row

5.7-Inch LCD Panel —
Professional Display Technology

The RD-839 uses a 5.7-inch LCD
display panel — significantly
larger than the 2.5–3.5 inch
panels found in consumer
projectors. A larger LCD panel
delivers several critical advantages
for high-brightness projection:

• Better heat management —
  larger panel surface area
  dissipates heat more
  effectively during
  extended use sessions
• More uniform brightness —
  light is spread more
  evenly across a larger
  panel for consistent
  brightness edge to edge
• Higher durability —
  designed for commercial
  continuous-use environments
  rather than casual
  home viewing
• Better colour accuracy —
  larger panel allows
  more accurate colour
  reproduction at
  high brightness levels

10,000:1 Contrast Ratio —
Cinema Quality Picture

Despite its enormous brightness
output the RD-839 maintains
a 10,000:1 contrast ratio —
matching the CUBELITE ULTRA
for the highest contrast
rating in the Digital Minds
India projector range.

This exceptional contrast ratio
means the RD-839 does not
sacrifice picture quality
for brightness — dark scenes
in movies and presentations
retain deep blacks and
shadow detail even at
maximum brightness output.
The result is a picture
that is simultaneously
extremely bright and
genuinely cinematic.

300-Inch Maximum Projection —
The Biggest Screen Available

The RD-839 projects from 35 inches
up to a massive 300 inches — the
largest maximum projection size
available in the Digital Minds
India range. A 300-inch screen
is approximately 6.6 metres wide
and 3.7 metres tall — larger
than many cinema screens in
Indian multiplexes.

This makes the RD-839 ideal for:

• Outdoor movie screenings
  for large audiences
• Stadium and sports venue
  display installations
• Wedding reception and
  banquet hall projection
• Corporate product launch
  and event presentations
• Church, temple and
  community gathering
  large format display

Auto Focus & Auto Keystone —
Professional Setup Convenience

Despite its commercial-grade power
the RD-839 is designed for fast
and easy setup:

• Auto Focus —
  automatic image sharpening
  on power on — no manual
  focus adjustment needed
  even on 300-inch projections
• Auto Keystone —
  automatic distortion
  correction for a perfectly
  rectangular image regardless
  of projector placement angle

This is particularly valuable
for event and venue use —
where the projector may be
set up and taken down
repeatedly in different
locations and configurations.

Android 9 — Smart Streaming
& Content Management

The RD-839 runs Android 9 —
providing direct access to
streaming platforms, content
management apps and
presentation tools
without any external device:

• Stream YouTube, Netflix
  and OTT content directly
• Run presentation apps
  for corporate and
  event use
• Access Google Play Store
  for additional apps
• Connect to WiFi
  (2.4GHz / 5GHz) for
  wireless streaming
• Pair Bluetooth 5.0
  speakers or audio
  systems for large
  venue audio

With 1GB RAM and 8GB storage
the RD-839 handles essential
streaming and presentation
tasks reliably — while
the LAN port provides
a wired internet option
for maximum stability
in commercial
installations.

Professional Connectivity Suite

The RD-839 is equipped with the
most comprehensive connectivity
for commercial and event use:

• Dual HDMI —
  connect two HDMI sources
  simultaneously — laptop,
  media player, gaming
  console or video processor
• Dual USB —
  two USB ports for
  simultaneous media
  playback and storage
• AV Input —
  connect legacy devices,
  cameras and older
  AV equipment
• Audio Out —
  connect to external
  PA systems, speakers
  or amplifiers for
  large venue audio
• LAN (Ethernet) —
  wired internet for
  maximum stable streaming
  in permanent installations
• WiFi 2.4G/5G —
  dual-band wireless
  connectivity
• Bluetooth 5.0 —
  wireless audio device
  pairing

The Audio Out port is particularly
important for large venue use —
connect directly to professional
PA systems, sound mixers and
amplifiers for room-filling audio
that matches the scale of the
RD-839’s massive projection.

Universal Power Input —
Global Compatibility

The RD-839 accepts 110–240V /
50–60Hz universal power input —
compatible with Indian power
standards (230V/50Hz) and
all international power systems.
Ideal for event companies and
AV rental businesses that
operate across different
venues and countries.
