Combined with the MSB in Register 0x4B, the bits indicate the
last line of active video. All lines past this comprise a lower
horizontal bar. This is used in letter-box modes. If the 2-byte
value is greater than the number of lines in the display, there is
no lower horizontal bar.

O ^{0x43—Bits[7:0] EDID Read Address}
Combined with the MSB in Register 0x4D, these bits indicate
the first pixel in the display that is active video. All pixels before
this comprise a left vertical bar. If the 2-byte value is 0x00, there
is no left bar.
0x4D—Bits[7:0] Active Pixel Start MSB
See Register 0x4C.
0x4E—Bits[7:0] Active Pixel End LSB
Combined with the MSB in Register 0x4F, these bits indicate
the last active video pixel in the display. All pixels past this
comprise a right vertical bar. If the 2-byte value is greater than
the number of pixels in the display, there is no vertical bar.
0x4F—Bits[7:0] Active Pixel End MSB
See Register 0x4E.

0x48—Bits[7:0] Active Line Start LSB
Combined with the MSB in Register 0x49, these bits indicate
the beginning line of active video. All lines before this comprise
a top horizontal bar. This is used in letter-box modes. If the
2-byte value is 0x00, there is no horizontal bar.
0x49—Bits[7:0] Active Line Start MSB
See Register 0x48.
