0x7B—Bits[7:0] CTS (Cycle Time Stamp) (19:12)
These are the most significant 8 bits of a 20-bit word used in the
20-bit N term in the regeneration of the audio clock.
0x7C—Bits[7:0]CTS (11:4)
0x7D—Bits[7:4] CTS (3:0)
0x7D—Bits[3:0] N (19:16)
These are the most significant 4 bits of a 20-bit word used along
with the 20-bit CTS term to regenerate the audio clock.

0x84—Bits[6:0] Video ID Code
See CEA EDID short video descriptors.
0x85—Bits[3:0] Pixel Repeat
This value indicates how many times the pixel was repeated.
0x0 = no repeats, sent once; 0x8 = 8 repeats, sent 9 times; and
so on.
0x86—Bits[7:0] Active Line Start LSB
Combined with the MSB in Register 0x88, 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.
Picture Scaling
No known nonuniform scaling
Has been scaled horizontally
Has been scaled vertically
Has been scaled both horizontally and vertically
