9.1 Input Digital/Analog selection
The Universal DVI (DVI-U) inputs are capable of receiving a number of different signals.
Set the input to the expected signal type by the
typechoice
API command.
For example:
slots.slot1.in1.typechoice = DVI
The current options are:
DVI
selects the Digital input (use for HDMI)
RGBHV
Analog RGB with separate HV
RGsB
Analog RGB with sync on Green
YUV
YUV with sync on Y (use for YPbPr)
YC
Luminance
and
Chrominance
CV
Composite
Video
The CV signal is applied to the analog green input and the separate YC is applied to the
blue and red inputs respectively.
Note: The YUV setting is also used for YPbPr where the unit switches between the two
color spaces depending of the incoming resolution.
9.2 Input Brightness and Contrast
The input brightness and contrast can be adjusted in the command line to permit
correction for incoming signals.
This is performed using the
brightness
and
contrast
commands.
For example:
slots.slot1.in1.brightness =
x
(where
x
is an integer between -32 and 32)
slots.slot1.in1.contrast =
x
(where
x
is an integer between 30 and 130)
The brightness value range of -32 to 32 lifts or lowers the signal level. The contrast value
of 30 to 130 represents the gain adjustment and is the percentage of gain where 100 is
unity gain.
9.3 DVI-U / HDBaseT Digital Output Resolutions
The output resolution can be set via the command line. The CORIOmatrix reads the EDID
table from any connected monitor and compares the list with the resolutions the unit is
capable of producing.
