Select a Resize Presets option 
to quickly display an image in 
its native resolution or to 
automatically resize an image 
to closely fill the projector’s 
native resolution of 2048 x 
1080, or to optimize the width 
or height of your display. Size, 
Position and Blanking 
parameters will automatically 
adjust accordingly. Or, if Blanking is set first, which defines an Active Input Area,

• Select
 “FULL SCREEN” to use all pixels (2048 x 1080) 
for displaying the image, regardless of source or 
original aspect ratio. See right. 
• Select 
“FULL WIDTH” to fill the projector’s display from left-to-right without 
changing the original aspect ratio of the image. Depending on the source, data at 
the top and bottom may be discarded (cropped), or the display may have black 
borders at the top and bottom. See below.

Pixel Track 
Steady flickering or several soft vertical stripes or bands across the entire image 
indicates poor pixel tracking. Proper pixel tracking helps ensure that the image 
quality is consistent across the screen, that aspect ratio is maintained, and that pixel 
phase can be optimized (described below). Tracking determines the frequency of the 
pixel sampling clock, indicated by the number of incoming pixels per line, so that all 
pixels generated by a...

Advanced Size and Position — SUBMENU 
This submenu consists of the 
following options: 
ACTIVE INPUT WINDOW: This 
read-only value indicates the 
current size (i.e., area) of your 
displayed data or “region of 
interest” as defined by the 
blanking controls. For example, if 
you have blanked (cropped) 100 pixels from both the left and right edges of an 
incoming source of 2048 x 1080, the remaining active input window will be 1848 x 
1080. When using a video...

PLUG & DISPLAY (EDID): By default, a Plug & Play 
(EDID) source outputs a signal according to the EDID 
information provided by the projector. To override 
this information and display in a different format (for 
example, if your Plug & Play [EDID] device does not 
support the projector’s resolution and/or frequency), 
select the desired Plug & Play (EDID) resolution 
from the list. 
Any daisy-chained projectors will also display 
according to the chosen Plug...

Gamma 
(
SHORT CUT: Press Gamma and adjust the slidebar.) 
“Gamma” is a global setting that determines what gray shades are displayed between 
minimum input (black) and maximum input (white) for all signals. A good gamma 
setting helps to optimize blacks and whites 
while ensuring smooth transitions for the 
“in-between” values utilized in other colors. 
Thus, unlike brightness and contrast settings 
controls, the overall tone of your images can 
be lightened...

override this and manually set a specific color space. 
NOTE: For most digital signals or for signals connected to 
INPUT 3 or INPUT 4, the 
color space function is entirely automatic and the pull-down list disabled. 
The current color space appears in the Image Settings menu. Press

values to stabilize. Alternatively, do not use “Auto”—reduce blacklevels 
manually instead. Judge by eye and change one or more of the six levels 
as necessary to obtain proper blacks and whites. You may want to see 
only a certain color while adjusting—use the “Color Enable” option 
(described below).
