12.2.7 DisplayPort unit (VM-1820, 1820A)
The dot clock frequency is restricted by the pattern drawing bit length (Color Depth) shown in the figure
below. Data skipping occurs when the output video bit length (Video Width) at this time is less than the
pattern drawing bit length (Color Depth).

Restrictions on dot clock frequency for DP1, DP2 (Dual/Split mode)
The maximum dot clock also depends on the DisplayPort Link Rate and other settings. For details, refer
to “11.1.8 DP unit”.
For details on the pattern drawing bit length (Color Depth), refer to “4.1.5 Setting the bit length (gray
scale) for pattern drawing”.
For details on the output video bit length (Video Width), refer to “4.12.2 DisplayPort setting procedure”.
Setting unit of horizontal timing
In Single Mode, H-timing should be set by 2-dot. In Dual/Split Mode, H-timing should be set by 4-dot.
Front porch setting value in interlace timings
Due to the restriction of the DisplayPort Transmitter, Horizontal front porch should be set by 32-dot or
higher, or vertical front porch should be set by 1H or higher.
Maximum vertical scanning lines
Due to the restriction of the DisplayPort Transmitter, 2046 is the maximum. (VM-1820 only)
