Bit 7, Halftone Output Delay on P20, is the amount of time that output of the
halftone signal is delayed to compensate for the amount of delay of OSD RGB
from external circuitries.
Bits 6, 5, and 4, Mesh Color, define the color of the mesh window. The colors are
specified in Blue, Green, Red order, as shown in Table 17.
