Usage Notice  
Eye Safety Warnings  
Avoid staring directly into the projector beam at all times.  
Minimize standing facing into the beam. Keep your back to  
the beam as much as possible.  
A stick or laser pointer is recommended to avoid the need for  
the user to enter the beam.  
Ensure that projectors are located out of the line of sight from  
the screen to the audience; this ensures that, when presenters  
look at the audience, they do not also have to stare at the pro-  
jector lamp. The best way to achieve this is by ceiling-mount-  
ing rather than floor or table-mounting the projector.  
When projector is used in a classroom, adequately supervise  
students when they are asked to point out something on the  
screen.  
In order to minimize the lamp power needed, use room blinds  
to reduce ambient light levels.

Recommendations  
To unleash the performance of the HD81-LV, it is best to input video  
content in its original form without any processing. This will utilize  
the full capabilities of the HD81-LV for de-interlacing, scaling and im-  
age enhancement. As an example, if a user has an HDMI DVD player  
capable of outputting the video signal in a 480i/576i digital format, we  
recommend feeding it directly to the HD81-LV without any processing  
by the DVD player. This will provide the HD81-LV with the original  
digital video stream and allow the HD81-LV to fully unleash its studio  
grade video processing.  
In general, we recommend the following:  
If possible, use digital output (DVD, D-VHS, DTV setup box, etc). If  
there is no digital output, use the component output terminals (YPbPr)  
with short and high-quality components cables.  
If you are unsure of the quality of the internal de-interlacing or scaler  
of your video source, let HD81-LV do the processing by connecting to  
the interlaced component output.  
If possible, leave out any extra video processing in your video source  
(DVD, D-VHS, and HDTV STB).  
Some HDTV STB models have scaling conversion that will output  
1080i from a 720p format. Try to output 1080i in its native signal for-  
mat and let HD81-LV perform deinterlacing and scaling.  
Not all HDMI DVD players have a digital interlaced output  
(480i/576i). For these products, it is suggested that users try 480p/576p  
first, followed by 720p and 1080i. After viewing the full range of out-  
put resolutions, the user can then judge which is the best image quality  
and set the HD81-LV for that resolution.  
Many high-end analog output DVD players also come with high qual-  
ity DAC with 12 or 14 bits of processing.  
Again, the users should try setting their 480i/576i output to HD81-LV  
first.  
HD81-LV has BNC connectors for component video input. If the user  
plans to use analog component to connect to their video source, for the  
best image quality, it is recommend using the BNC connectors.  
For connecting to Laser Disc player or S-VHS deck, we suggest to use  
S-video output connection to connect to HD81-LV.  
It is best to have a separate power outlet for audio and video equip-  
ment.

Connecting HD81-LV To AV Receiver  
For maximum flexibility when integrating into existing  
entertainment systems, the HD81-LV Video Box is equipped  
with 2 HDMI outputs. One output directly sends the signal out  
to the projector and the second output sends the signal out to an  
HDMI equipped AV receiver. There are three ways to connect  
the HDMI output from the HD81-LV’s Video Box.  
Option 1  
Using HD81-LV’s Video Box as video source selector and HDMI  
equipped AV Receiver for audio:  
If you have an HDMI equipped AV receiver and wish to send the audio signal  
to the receiver, but utilize the HD81-LV’s Box as the video source selector:  
1) Connect the video sources to the HD81-LV’s video Box.  
2) Attach an HDMI cable to the “To AV Receiver” port on the back of the  
HD81-LV’s Video Box. Connect the other end to your AV Receiver. This will  
allow the audio signal to be controlled by the AV Receiver.  
3) Attach a 2nd HDMI cable to the AV out port on the back of the AV Receiver.  
Connect the other end to the “From AV Receiver” on the back of the HD81-  
LV’s Video Box. This will return the video signal in a “pass through” mode.  
4) Connect an HDMI Cable to the “To Projector” on the back of the HD81-LV’s  
Box side. Connect the other end to HD81-LV’s projector side.

Installation  
Option 2  
Using HD81-LV as video source selector and directly connecting the  
video source to the AV Receiver:  
If you do not have an HDMI equipped AV receiver, to ensure proper audio  
connections, you will need to directly connect the Audio out from the Video  
source to your receiver. The HD81-LV will be used only to process the Video  
signals.  
1) Connect the video sources to the HD81-LV’s Video Box.  
2) Connect the video sources audio out directly to your receiver.  
3) Attach the short HDMI cable that comes standard with the unit to the “To  
AV Receiver” port on the back of the HD81-LV’s Video Box. Connect the  
other end to the “From AV Receiver” port on the back of the HD81-LV’s  
Video Box. This will allow the video signal to be properly managed.  
4) Connect an HDMI Cable to the “To Projector” on the back of the HD81-LV’s  
Box side. Connect the other end to HD81-LV’s projector side.  
Option 3  
If you have a single HDMI source, you can hook the Video source  
directly up to the “From AV Receiver” port on the back of the HD81-  
LV’s Video Box. Connect a second HDMI cable to the “To Projector”  
port on the back of the HD81-LV’s Video Box and attach the other end  
to HD81-LV’s Projector side.  
This configuration only process high resolution video for HD81-LV’s projector.

ISF Modes  
For care-free operation, HD81-LV comes with ISF Modes.  
The HD81-LV is designed to offer exceptional performance “out of  
box”; but since lighting and other factors can affect the performance  
of your display device, Optoma offers ISF calibration capability. After  
the ISF calibration, the user can simply switch among the two ISF Day  
and Night modes to have certified image effects.  
Day and Night modes are locked at the factory and require certified  
ISF calibrators to unlock and set-up. Certain factors cannot be set at  
the factory due to variables during the setup. Professional calibration  
of Day and Night modes allow for the appropriate setting of contrast,  
tint, sharpness, color levels and other parameters to exactly match the  
environment where the display device is used. There are also three  
user modes which can be modified by the user, allowing a total of five  
settings per signal/connection to match every condition.  
For ISF calibration, please visit www.imagingscience.com to find a  
certified ISF technician in your area.

Format  
Use this function to choose your desired aspect ratio.  
To match the input image to the correct aspect ratio, six modes can  
be selected: 16:9, 4:3, Native, LBX, Format 1, Format 2.  
Default modes are 16:9, 4:3, Native and LBX.  
4:3: This format is for 4x3 input sources not enhanced for  
Wide screen TV.  
16:9: This format is for 16x9 input sources, like HDTV and DVD  
enhanced for Wide screen TV.  
Native: This format displays the original image without any  
scal-ing. (*)  
(*): When Ana-  
morphic Lens set as  
“Fixed” or “Movable”,  
the default format will  
become “Auto235” that  
replace original format  
“Native”. (See page 35)  
LBX: This format is for non-16x9, letterbox source and for users  
who use external 16x9 lens to display 2.35:1 aspect ratio using  
full resolution.  
Detail information about LBX mode :  
1) Some Letter-Box DVD contents are not enhanced for 16x9 TV,  
then image will not look right in 16:9 display.  
One can use 4:3 mode to view the correct info.  
But if the content itself is not 4:3, it will have black bars around  
the image in a 16:9 display. For this kind of content, you can  
use LBX mode to fill the image in the 16x9 display as much as  
possible.  
2) If you use an external 16x9 lens, this LBX mode also allows  
you to watch a 2.35:1 content (include Anamorphic DVD and  
HDTV film source) that support anamorphic wide is enhanced  
for 16x9 Display in a wide 2.35:1 image.  
In this case, there are no black bars, the full lamp power and  
vertical resolution is fully utilized for maximum viewing  
effects.  
Other than these two occasions, one should stay with 16:9 and  
4:3 modes for most viewing experiences.  
At this time, the exact aspect ratios for Format 1 and Format 2 have  
not been defined. For maximum flexibility, Format 1 are pre-set as  
16:9 mode and Format 2 is pre-set as Letter Box.  
User can also quickly select each mode from the remote control by  
pressing the “Display Format” button.
