Welcome to LASERVUE® TV!  Mitsubishi has created a 
new category of television with laser technology.  Laser 
beams provide the widest range of rich, complex colors, 
along with the most clarity and depth of field.  Precise 
and focused, the purity of laser light far surpasses 
current high-definition technologies and sets a new 
standard for premium large-screen television.
Your new high-definition widescreen television has 
many special features that make it the perfect center of 
your home entertainment system, including:
1080p High-Definition DLP  Display System
Your Mitsubishi HDTV uses Texas Instruments Digital 
Light Processing™ technology for rear-projection TVs 
to create the picture you see on screen.  All images are 
displayed at 1080p. The TV uses Plush 1080p® 5G to 
convert lower-resolution signals to 1080p for display.  
The TV can also accept 1080p original signals and main-
tain them at 1080p through all processing until displayed.
3D Ready
All Mitsubishi 1080p LASERVUE HDTV’s are 3D Ready.  
This feature lets you experience the new 3D technolo-
gies applied to many recent movies and video games.  
Immerse yourself in your favorite video game, movie, or 
sporting event displayed in 3D.
Integrated HDTV Tuner
Your widescreen Mitsubishi LASERVUE HDTV has an 
internal HDTV tuner able to receive both over-the-air 
HDTV broadcasts (received via an antenna) and non-
scrambled digital cable broadcasts, including non-
scrambled HDTV cable programming.
High-Definition Video Inputs
Component Video Inputs.•	  Also called Y/Pb/Pr 
inputs, these inputs receive standard analog video 
formats of 480i, 480p, plus 720p and 1080i high-
definition signals.  This provides a high level of 
flexibility when connecting DVD players/recorders, 
cable boxes, and satellite receivers.
HDMI Inputs.•	  These inputs accept digital 480i, 
480p, 720p, 1080i, and 1080p video signals plus 
PCM digital stereo signals.  The HDMI™ inputs can 
also accept a variety of PC signals and resolutions.  
These inputs support HDMI 1.3 Deep Color (up to 
36 bits) and the x.v.Color extended color gamut.
Used with an adapter, these HDMI inputs also 
accept compatible digital DVI video signals.  HDMI 
inputs provide additional high-performance, 
high-definition connections for maximum flexibility 
in your choice of home theater products. The HDMI 
inputs are HDCP copy-protection compatible.
Easy Connect Auto Input Sensing
Easy Connect™ Auto Input Sensing automatically rec-
ognizes when you plug in a device and prompts you to 
assign a name to it.  The TV ignores any unused inputs, 
so the result is an uncluttered menu where you can 
easily find and select connected devices by name.
Home-Theater Control
HDMI Control
HDMI devices with Consumer Electronics Control 
(CEC) capabilities may be compatible with the TV’s 
HDMI Control feature.  Compatible devices can receive 
control signals through the HDMI connection, allowing 
the TV’s remote control to operate some functions of 
these devices.
NetCommand with IR Learning
Model L75-A91.  Your Mitsubishi HDTV offers a new 
level of networking that seamlessly integrates selected 
older A /V products with new and future digital prod-
ucts.  NetCommand® supports IR (infrared) control of 
products such as VCRs, DVD players, cable boxes, and 
satellite receivers.  NetCommand can “learn” remote 
control signals directly from many devices, allowing you 
to create a customized NetCommand-controlled home-
theater system.
Internet-Video Ready
Model L75-A91.  Built-in VUDU™ connectivity lets you 
stream high-definition internet video content directly to 
your TV.  Access to VUDU’s fee-based movie service 
is through menus displayed on the TV.  VUDU offers the 
largest on-demand HD movie selection anywhere, featur-
ing full 1080p and 5.1 surround sound.  VUDU allows you 
to enjoy movies with no store visits, no mailing, no late fees 
and no subscriptions.
