I am developing an LCD controller, and some of the code for my (third-party) timing generator includes horizontal and vertical front/back porch and vsync/hsync pulse time information for a different LCD module.
The datasheet for the LCD I'm actually using has horizontal/vertical porch and pulse times, and these vary (in some cases substantially) from my third party code.
However, my understanding is that the porches, etc., really only matter for analog video, and that the data enable bit is the most important.
The sync pulses are where I'm a little hazy.
Is it likely to make any difference if I go back and edit the third-party timing generator code to use the same porch and pulse timings?
