Is Figure 2 in reference manual for Pmod VGA incorrect?

[Mike.H]

While trying to understand the timing signals for the Pmod VGA, I noticed a discrepancy between the location of the "front porch" in Figure 2 vs. Figure 3 in the reference manual. After cross referencing with the demo code and Wikipedia, it appears that Figure 2 is incorrect. That is, the front porch should occur immediately before the sync pulse, whereas Figure 2 illustrates it coming immediately after the sync pulse where the back porch should be.

Hi @Mike.H,

You are correct, Figure 2 is incorrect in it's placement of the front porch, and it should be before the sync pulse as shown in Figure 3; good catch.

I will see if I can get this image (and all of the other images in other pieces of documentation) corrected.

Thanks,
