I do not believe display resolution has anything to do with ligature use. The purpose of ligatures are to improve the character spacing visually when the smallest space was a point size (only 72 dpi). They really wouldn't be needed at all if the resolution was high enough to adjust the spacing on a character by character basis. Of course the actual outline shape might look a little better with high resolution but this is not a ligature issue and anti-aliasing techniques pretty much take care of this anyway.
I do believe that the source eBooks should never use ligatures. Ligatures should be added by the rendering engine as one method among others to improve character tracking. EBooks should be sources and not attempt to force rendering, fix tracking, etc. You can read about
