Up-Scaling
The on-board scaler provides up-scaling (magnification) of video, RGB and VN-GLIMPSE sources.
Independent horizontal and vertical scaling is possible up to 16x native resolution. For example, a
source of 720x486 pixels can be scaled up to around 11520x7776 pixels.
The scaling engine is built around Electrosonic’s patented convolver technology which ensures that
original image detail and quality is maintained at all times.
Down-scaling (minification) of video, RGB and DVI sources is achieved by a scaler on
the Input Card. See page 75 for further details on source scaling.
NOTE: Where image files need to be up-scaled, these are rendered at the appropriate size by the on-
board graphics processor (GPU). This ensures maximum image sharpness.
Output Channels
Two output channels are provided which can be used to drive separate displays or individual screen
elements within a larger tiled display.
In a tiled display, each Output Card channel pair can be configured to output any region of the overall
display.
All outputs are compatible with analog or digital display devices. Output resolution is adjustable up to
UXGA (1600 x 1200 pixels) and 1920 x 1080p with refresh rates of 50 or 60Hz.
