7.6 ScenergiX
7.6.1 Introduction
Why ScenergiX ?
When working in a multichannel setup the Projector Toolset and its Soft Edge possibilities enable an image
blending that gives the appearance of a single view, thus achieving realistic immersion for the majority of
wide screen applications.
ScenergiX is limited to half the resolution of the projector.

What is the Basic Principal of ScenergiX ?
The principle of edge blending is achieved by linear modulation of the light output in the overlap zone so
that the light output in that zone equals the light output of the rest of the image.

ScenergiX Basic Principle
7.6.2 Preparations
ScenergiX Preparations
To ensure proper ScenergiX adjustment, be sure that the following adjustments are done perfectly on all
projectors:
• Convergence
• Geometry
• Color Matching (Color Temperature, Color Standard, Input Balance, Gamma)
7.6.3 ScenergiX activation
How to enable or disable ScenergiX
1. To enable ScenergiX, check the check box in front of enable.
To disable ScenergiX, uncheck the check box in front of enable. (image 7-13)
When enabled,Show alignment linesbecomes available.
2. To display alignment lines on the screen, check the check box in front ofShow alignment lines.

7.6.4 ScenergiX overlap zone (horizontal ScenergiX)
Definitions
Image 7-14
ScenergiX set up
Overlap : number of pixels that overlap
Horizontal resolution of 1 projector : 1024 for Graphics versions, 1280 for Reality versions, 1400 for SXGA
projectors.
Total horizontal screen resolution : [(horizontal resolution of 1 projector) x 2] minus overlap.
Horizontal Resolution source : number of active pixels of the source.
Adjustment of Active pixels of thefirst projector
1. Go toAdjustmenttab –>Input settingspane –>Adjustmenu offirst projector.
2. Enter value for horizontal active as follows :
Horz. active= [(Horz. resolution of 1 projector)/(Total horz. screen resolution)] x (horz. resolution
source)
3. Horizontal start remains the same.
Adjustment of Active pixels (Pact) of second projector
1. Go toAdjustmenttab –>Input settingspane –>Adjustmenu of second projector.
2. Enter value for horizontal active as follows :
Horz. active= [(Horz. resolution of 1 projector)/(Total horz. screen resolution)] x (horz. resolution
source)
3. Horizontal start = original start + [(Horz. resolution source) minus (newly calculated Horz. active)]
Example
Horizontal resolution source : 1600 pixels
horizontal resolution projector 1 & 2 : 1024 pixels
Overlap : 100 pixels
Total horizontal screen size in pixels : 1948 pixels
Horz; active projector 1 = [(1024 / 1948)] x 1600 = 841 pixels
Horz. active projector 2 = [(1024 / 1948)] x 1600 = 841 pixels

7.6.5 ScenergiX overlap zone (vertical ScenergiX)
Definitions
Image 7-15
Scenergix overlap zone vertical
Overlap : number of pixels that overlap
Vertical resolution of 1 projector : 768 for Graphics versions, 1024 for Reality versions, 1050 for SXGA
projectors.
Total vertical screen resolution : [(Vertical resolution of 1 projector) x 2] minus (overlap)
Vertical Resolution source : number of active lines of the source
Adjustment of Active lines (Lact) of thefirst projector
1. Go toAdjustmenttab –>Input settingspane –>Adjustmenu offirst projector.
2. Enter value for vertical active (= Lact) as follows :
Lact = [(vert.. resolution of 1 projector)/(Total Vert. screen resolution)] x (Vert. resolution source)
3. Vertical start (= Lstart) remains the same.
Adjustment of Active lines (Lact) of second projector
1. Go toAdjustmenttab –>Input settingspane –>Adjustmenu of second projector.
2. Enter value for vertical active (= Lact) as follows :
Lact = [(vert.. resolution of 1 projector)/(Total Vert. screen resolution)] x (Vert. resolution source)
3. Vertical start (= Lstart) = original start + [(Vert. resolution source) minus (newly calculated Lact)]
Example
Vertical resolution source : 1200 lines
Vertical resolution projector 1 & 2: 768 lines
Overlap : 50 lines
Totalverticalscreensize: 1486lines
Lact projector 1 = (768 / 1486) x 1200 = 620 lines
Lact projector 2 = (768 / 1486/) x 1200 = 620 lines
Lstart projector 2 = Lstart projector 1 + (1200 – 620)

7.6.6 ScenergiX size adjustment (white level adjustment)
What can be done with the manipulations pane?
The Top, bottom, left or right item set the blending zone.

Width selection
How to set a blending zone
1. Click on the up down control of the spin box of the selected blending zone and adjust until the desired
zone is reached (image 7-17)
Or,
click in the inputfield of the spin box of the selected blending zone and enter the desired value.
The result is indicated in the ScenergiX preview pane. The corresponding line will move in the selected
direction.
WhenShow alignment linesis checked, the zone indication is shown on the screen. The corresponding
zone will move in the direction of the adjustment.

7.6.7 Adjusting the black level of the images
Why black level adjustment
For dark images, the overlap zone will be brighter then the rest of the images. Typically for DLP projectors,
next to the overlap zone, a brighter area is recognized. This area is known as a DLP leakage area. This
area must also be exclude for the black level adjustment. Therefore we can rise the black level of the
remaining image (excluding the overlap zone and the DLP leakage area).
First, the width of the leakage area must be set. The white cursor line indicates the border of the overlap
area. The green cursor line indicates the current installed DLP leakage area border and starts at the
position of the white cursor line (no width installed). This green line can be moved to the border of the
DLP leakage area with the cursor keys.

How to set the leakage area width
1. Click on the up down control of the spin box of the selected leakage zone and adjust until the desired
zone is reached (leakage area is covered)
Or,
click in the inputfield of the spin box of the selected leakage zone and enter the desired value. (im-
age 7-19)
WhenShow alignment linesis checked, the corresponding green line on the screen will move in the
same direction. The leakage area is defined and will be excluded during black level adjustment. (im-
