Hi Jonathan,

[quote user="Jonathan Valdez"]1) From my research on E2E, it appears as if the AM335x controller supports both sync methods (please confirm).[/quote]

Yes, the LCD_AC_BIAS_EN signal acts as DE for raster displays.

[quote user="Jonathan Valdez"]2) Are there any distinct advantages to choosing one method over the other? I have not been able to find any literature highlighting the differences.[/quote]

It's not a matter of advantage or disadvantage, it's a LCD display requirement.
