The always high resolution setting are some what random for 9anime some times they give 480p and some times have give out 780p

That setting doesn't exist. There is a setting "Kissanime preferred resolution" where you can choose "HQ: use the highest resolution" but it was used on kissanime server only. That setting will probably be removed in the future.
