b) Concerning the Bit length setting
BIT length setting is available only for the below setting of Video Format.
Video Format
bit Width
6bit 8bit 10bit 12bit
RGB Yes Yes Yes N/A
YCbCr4:2:2 Yes Yes Yes Yes
YCbCr4:4:4 Yes Yes Yes N/A
c) Concerning the Main Stream Attribute settings
The Main Stream Attributes used for DisplayPort transfer are reflected by the following settings.
Item Setting location
M and N for stream
clock recovery Mvid
This is automatically calculated from the Nvid setting value
and the dot clock.
(The VG-876 is fixed to asynchronous mode, so the Mvid
value varies.)
Nvid
(VM-1876A-M1
does
not support Nvid.)
The setting is followed by the
DisplayPort setting “Nvid”.
Refer to “<DP unit setting parameters>” in this section.
Horizontal/Vertical
Timing Total
Active start
Active video width
Sync width
This is calculated from the value set by the Timing setting.
polarity
The setting is followed by the sync signal polarity set by the
Output setting.
Miscellaneous0 Synchronous Clock The VG-876 is fixed to asynchronous mode.
Component format
The setting is followed by the DisplayPort setting “Video
Format”.
Refer to “<DP unit setting parameters>” in this section.
Dynamic range
The setting is followed by the level mode setting of the output
setting.
Full:
VESA range
Limited: CEA range
YCbCr Colorimetry
The setting is followed by the DisplayPort setting
“Colorimetry”.
Refer to “<DP unit setting parameters>” in this section.
Bit depth per color
component
The setting is followed by
the DisplayPort setting “Width”.
Refer to “<DP unit setting parameters>” in this section.
Others Settings except above are not supported by the VG-876.
