Multiple Unit
The HQView-310 and HQView-320 have a Multiple Unit menu for use in a multi screen application.
Multiple screens are stitched together to provide a bigger display with higher resolution than a single
display. Each display is driven by a separate HQView unit.
When using the Auto Zoom function - Each HQView unit gets the same graphics or video input signal
through a distribution amplifier. The HQView unit cuts out and resizes the image to display the part of
the image assigned to the corresponding screen.
Soft Edge Blending - In a multi projection display the individual projections typically are chosen to
overlap to give seamless transitions. Overlapping regions are illuminated by multiple projectors and are
brighter than non-overlapping regions. For a uniform brightness over the total display the brightness in
the overlapping regions has to be reduced electronically.
Important: When using multiple HQView units to drive one single large screen, it is essential that all
HQView units are I/O locked, otherwise motion tear will be observed at the boundaries of the image
processed by each HQView unit. It is also essential that all HQView units are setup for the same
processing latency (either all units are in Best Picture mode or all units are in Low Latency mode).
3.10.1.
Auto Zoom
Available Settings: On, Off
Auto zoom cuts and resizes the video image to display the assigned part of the total image.
Please note:- AutoZoom is switched off automatically when the on-screen menu cannot be properly
displayed. The menu is part of the output and is scaled by the warp engine. There are scenarios when
the menu may exceed the size of the screen and also only the active video area can be used for the on-
screen menu, this would crop the menu and make it impossible to navigate.
A message will indicate such situations. After having made suitable changes the AutoZoom function can
be reactivated.
3.10.2.
Units Wide/Units High
Available Settings: 1, 2, 3, 4 horizontal / 1, 2, 3, 4 vertical
Provides the HQView unit with information of the multi screen installation. The number of horizontally
and vertically installed screens or projectors is entered.
3.10.3.
Horizontal Pos/Vertical Pos
Available Settings: 0 to 3 horizontal / 0 to 3 Vertical
Provides the HQView unit with the information of which window of the total image it is assigned to. If
autozoom is on this tells the unit which part of the image cut out and resize. This selection also
determines which edges of the picture are provided with soft edge blends.
