   Bring Interactivity to the Classroom

transforms any existing flat surface into 
an interactive workspace. Delivering 
genuine benefits, these bundles

gestures) but also are quick and easy 
to use
•  DisplayNote
® multiuser license allows 
you to present, share, and collaborate across any device or platform
•  Fast and easy auto-calibration means you are up and running in no time
•  2x super-fast charging pens are included
•  With multiple pens, annotation and presentation at the board has never 
been easier. Whether one pen is charging while the other is in use or 
two people are at the board, new levels of collaboration are possible
•  Interaction and annotation can take place at the board or from a mobile 
device (using DisplayNote
®) at the same time creating a completely 
immersive lesson.
The U321H ultra short throw projector touts 
advancements such as an integrated pen system 
and were designed with a feature set that makes 
them ideal for use in educational settings.
   Essential Features for Ease of Use
• Bright images can be easily viewed in most applications
•  Intuitive remote control provides one-touch source changes and 
complete menu control
•  Integrated RJ45 connection for quick connection to the LAN (10/100 
base-T capability
•  Remote diagnostics enable the user to monitor and make adjustments 
to the projector remotely
•  Plug and Play setup and operation optimizes images displayed from 
computers and video sources
   Versatile Features and Powerful Performance
• Powerful 8-watt speaker provides volume needed for medium sized rooms
•  Variable audio-out enables remote control to be used to adjust volume 
of self-powered external speakers that are connected to the projector. In 
stand-by mode, the audio-out stays active, allowing the last input used 
to pass to the self-powered external speakers.
•  Virtual Remote™ (DDC/CI) over the VGA cable or via the network 
connection (wired/wireless) allows you to control the projector directly 
from a computer without the need for additional control cables
•  Native 1080p resolution projectors automatically sync with higher-
resolution computers
•  Flexible input panel connects with dual HDMI, computer, composite 
video and component video (using optional 15-pin adapter cable)
   Designed with the Environment in Mind
• Extended lamp life with ECO Mode™ technology increases lamp life up to 
4000 hours, while lowering power consumption and maintenance costs
•  Power management enables projector to automatically turn off when 
an incoming signal is not detected from any of the inputs
•  Auto Power On, using the Direct Power On mode, turns on the 
projector when AC power is supplied
•  Quick start (20 seconds) lets you begin presenting in seconds while 
quick shutdown (immediate power off with no cooling required after 
shutdown) ensures efficient energy usage
• NEC is committed to designing its products to provide long lifecycles. 
The new virtually maintenance-free filter (4000 hours) reduces the 
frequency at 
which cleaning is 
required, thereby 
decreasing total 
cost of ownership
