Annex – Kaleido Display Resolution
The Kaleido-Alto/Quad displays all the elements of its layout in a frame whose maximum vertical resolution is
1024 pixels. However, the RGBHV output from all versions of the Kaleido-Alto and the Kaleido-Quad can drive
displays with greater vertical resolution, provided they are equipped with an appropriate hardware version (see
the chart below). In particular, displays operating at 1920x1080 and 1600x1200 can be used with these Kaleido
models.
1600 x 1200 resolution:
To drive a 1600x1200 display, the Kaleido layout must be created at 1600x1024 pixels. In KEdit, you must
generate a 25 x 16 display aspect ratio. When this layout is shown on the display, 88 lines on top and bottom
will be displayed in black.
1920 x 1080 resolution:
To drive a 1920x1080 display, the Kaleido layout must be created at 1920x1024 pixels. In KEdit, you must
generate a 15 x 8 display aspect ratio. When this layout is shown on the display, 28 lines on top and bottom will
be displayed in black (see figure A1).

A feature of Kaleido-Alto/Quad is the ability to replace the internally-generated background in the layout with
images from an external source, via the DVI input. In this case, it is appropriate to select a DVI background
source to match the display in use, i.e. 1600x1200 or 1920x1080. The background will occupy the entire
display screen, and the Kaleido-generated elements will be keyed into the vertically-centered 1024-line portion
of the screen, with no visible indication of any boundaries within the image (see figure A2).
Three sets of alternative “color keys” can be used by the background application. For example, in the case of
integration with iControl Web, the background uses (255 blue, 255 green and 0 red).
