1. What do the Horizontal and Vertical sync pulse values do and should I even touch them? They also seem to move automatically when I change porch values.
These are pretty much standard so there's little point in touching them. They are taken from the ntsc tv standard, so they're guaranteed to work on 100% of standard resolution CRTs.
I tried to modify the horizontal geometry to make it look like as close as possible to the picture from my Playstation 2.
Default Values: crt_range0 15625-16200, 49.50-65.00,
2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 1, 1, 192, 288, 448, 576
Modified values: crt_range0 15625-16200, 49.50-65.00,
4.730, 2.365, 9.460, 0.064, 0.192, 1.024, 1, 1, 192, 288, 448, 576
Does it look safe? Are these sane values? The picture looks good, but I just want to be safe.
