From the DMT VESA StandardThese settings change for various formats.
• HSOUT and VSOUT polarities and widths must be set correctly to be displayed properly.• Required dtg_hs_in and vs_in_dly settings depend on the source embedded sync alignment with RGB data. • If embedded syncs are aligned with the start of the front porch, dtg_hs_in_dly can be set based on the front porch. With this configuration, a constant delay of 41 needs to be added to the horizontal Fp when calculating dtg_hs_in_dly.
