*2 The DisplayPort output can be output at a horizontal timing of only 2-dot units in Single mode, or 4-dot units in
Dual or Split mode.
*3 When the YCbCr4:2:2 format has been selected, up to 12 bits can be set as the bit length. However, it is not
possible to display the gray scale which accords with the bit length (gray scale) which has been set (64-step gray
scale with an 8-bit output). Use this parameter to check the Main Stream Attribute parameters rather than using it
to assess the image quality.
*4 The maximum number of vertical scanning lines is 2046 for the DisplayPort output.
