Totally distinguishable. :) The hardware blocks seem similar upon cursory comparison of the register tables, with the base layout being the same, and sharing registers for basic settings such as the display timings. The DPI ones have some extra registers, presumably to control the signals or output width. The DP one has some registers of its own that only make sense for Display Port. ChenYu
