Blend adjustment procedure. Side by side configuration.
1. Starting with the left picture: By the arrow keys, place the display cursor on respectively the “ Enable ” zone and
the “ Show Lines ” zone and activate them by pressing enter.
2. Use the right arrow key to move the cursor to the “ Top Mask ” position in the menu. Press enter. From this
position the cursor can be moved around to the desired adjustment options.
3. Move the cursor to the “ Right Width ” position and press enter on the remote control.
4. Adjust the width value by using the arrow keys up (or down), one step at a time. By pressing the key arrow
constantly, the blend value will increase rapidly. The numeric value of the width is shown on the screen next to
the alignment line. (The number entered represent the blend width expressed in number of pixels). Confirm
position by pressing enter.
5. For the right picture, repeat the procedure, but adjust the Left Width instead of the right width. The numeric
value for the left width shall ideally be the same as for the right width for the left picture in the steps above.
6. Exit the menu by using the exit button on the remote control.
Adjustment procedure in over / under configuration.
For Blend adjustments in over / under configuration, the procedure is the same as for side by side, but use the
Top and Bottom height instead, and perform a similar procedure.
Use the numeric keys instead of the arrow key to set the values.
Instead of adjusting the lines by the arrow keys, the value can also be typed directly using the numeric keys on
the remote control.
To remove or undo the entered numbers, use the * key on the remote control.
8.5.4 Black level adjustment
About adjusting the black level
The Purpose of the black level adjustment is to adjust the black levels in the non overlapped areas with the
black level in the overlapped areas (Blend Zone).
This is a necessary function, due to the fact that the black level will be brighter in the blend zones, since
multiple projectors will add light in these zones.
The width of the black level area shall ideally be slightly larger than the width of the blend zone in order to also
compensate for the
“ sea of mirrors ” phenomenon.
The figure below shows how this occurs in a side by side configuration without any correction of the black
level.
