850 - Serial Protocol
Data
1. [block index]: From 0 to 7
Note: 7 is the preferred timing of the monitor, so it is
preferable to use 0 to 6
2. [perform immediately]: 1 = switch to the user-defined
resolution immediately, 0 = save the user-defined
resolution but do not switch
3. "H_": high bits
4. "L_": low bits
5. "data nH_4bits" and "data nL_4bits": As, 0xfa apart to
0x0f and 0x0a
6. The 18 data are the detailed timing of the EDID.

Data
data1: From 0 to 7
Data
data1: block index: from 0 to 7
data2: perform immediately: 0 = save the user-defined
resolution but do not switch, 1 = switch to the user-
defined resolution immediately
data3: predefined resolution number, from 0 to 35
Data
[group num]: from 0 to 0x3f. Each group has 8 bytes of
EDID data
When sending the command, there are 64 groups for 512
bytes of EDID data
