VIDEO INPUTS, OUTPUTS AND SCALERS
The 1T-C2-750 and 1T-C2-760 units both have two identical DVI-I inputs and one
DVI-I output.
6.1
DVI-I inputs
Each input can accept:
Digital DVI-D (maximum 1920x1200@60Hz / 1080p60)
(1T-C2-760 also supports 2880x900@60Hz)
Analog RGBHV
Analog RGsB (sync on green)
Analog RGBS (composite sync at TTL levels)
Analog YUV/YPbPr (including tri-level)
In most cases, the particular input being used will be auto-detected – with DVI-D
taking priority over any analog source. See ‘Adjust sources’ for more information
on manually selecting an input type.
6.2
PC/HD Scaler DVI-I output
The output can support DVI-D and an analog output type (as defined in ‘Adjust
outputs’) simultaneously:
Digital DVI-D (maximum 1920x1200@60Hz / 1080p60)
(1T-C2-760 also supports 2880x900@60Hz)
Analog RGBHV
Analog RGsB (sync on green)
Analog RGBS (composite sync at TTL levels)
Analog YUV/YPbPr (including tri-level)
The ‘Adjust outputs’ menu can be used to change the output resolution and the
sync/video format.
HD resolutions (such as 720p and 1080i) default to tlYUV (tri-level YUV) and
therefore may appear purple on a standard DVI monitor. This can be turned back
to RGBHV in the ‘Adjust outputs’ menu.

1T-C2-750 Block diagram
This unit has 2 scaling engines and 3 keyers whose outputs are mixed together to
form a single image, as in the block diagram below:
