Three digit hex number represents graphic vertical sync frequency times 10.
To obtain the final graphic vertical sync frequency divide the three digit hex number by 10.
The fourth hex number represents the scan mode:
“i” = interlace scan mode
“p” = progressive scan mode
0x32, 0x45, 0x44 = 0x2ED = 749 = 74.9 hertz
