I guess that would affect the gamma calculation as it will be dependent
on the LCD characteristics.
I guess the equation used will be
value_new = pow (value, 1.0 / factor)
where factor will be the gamma value. For the LUT, I will have to
calculate for the 0-255 that is assumming the gamma value is applicable
to red, green and blue instead of separate gamma values for each
colour. The previous design flow would have been wrong as I can't apply
the gamma to the YUV, I would need to convert the YUV to RGB and then
apply the gamma correction using the LUT.
Sorry, I am new to this subject.
A question on the AUO LCD module, from the datasheet I don't seem to be
able to find the gamma value for the monitor. What will be the name
within the datasheet?
The url for the datasheet is

For the gm2221 chipset, the adaptive color and contrast seem to be
applied to the YUV values. aitendo.sakura.ne.jp/download/gm2221.pdf
I guess I can always use this chipset instead of the FPGA options but
if I were to scale it down below 18 bit RGB, I will have to round it
down to required RGB and change the bit order for the LVDS
transmission.
