The maximum Horizontal and Vertical Display Widths shown in Table 13-5: “Minimum
and Maximum Values for NTSC/PAL” include display areas that are normally hidden by
the edges of the TV. The visible display dimensions are shown in Figure 13-5: “Typical
Total Display and Visible Display Dimensions for NTSC and PAL,” on page 196 as a
guideline. The actual visible display area for a particular TV may differ slightly from those
dimensions given. Table 13-6: “Register Values for Example NTSC/PAL Images” lists
register values for some example images.
