Are there some specific register value setting examples available for ADV7441A's "Auto Graphics Mode" as described on page 190, Section 9.15 of ADV7441A_HW_RevJ.pdf (ADV7441A

Hardware Database Manual Rev J June 2010) ? For example, to input from a VGA signal at 1600X1200-Pixel resolution(60Hz UXGA), what should we set the values for PLL_DIV_RATIO[11:0], FR_LL[11:0], LCOUN T_MAX[10:0] etc. registers? Are there some generic formula as for how to calculate the value settings for these related registers when given a target non-standard graphics input mode?
