Bits 31–0

These are the Display Window 2 Column Width 2x Enable Bits. These thirty-two bits correspond to columns

31–0 of Display Window 2, respectively. A value of zero indicates the column will have normal width (12 OSD

pixels). A value of one indicates the column will be twice as wide as normal (24 OSD pixels). For the double

wide case, each Character Font pixel location will be displayed twice, in two consecutive horizontal pixel

locations. The user should note that if more than 32 display characters are programmed to reside on a row,

then all display characters after the first thirty-two will have normal width (12 pixels).
