In fact, I tried \[\frac{a}{b}=\dfrac{a}{b}={\displaystyle \frac{a}{b}}\] (using LyX math insets, not ERT) and got a formula with three identical fractions.Article class, but lyx 1.4.5
I don't have 1.4.5, but I repeated the above experiment in 1.4.4, and again I got no differences. LyX file and DVI are attached.
\[ is marked as 'bad math environment delimiter' in 1.4 so i cannot check your test
I didn't mean that you should insert \[ and \]. What I listed above is the LaTeX produced by LyX. I used Insert->Math->Display formula, which provided the \[ and \] delimiters. Within the math inset, I typed \frac, \dfrac and \displaystyle \frac respectively, filling in the arguments.
