Whichever setting works best for your specific equipment at the end of the day .
Settings like these will always be variable & completely subjective, it's precisely why there are multiple options available as required by the user.
Have you also finally solved your screen flickering problem with your U9-H after multiple attempts at re-flashing the firmware? (Hope that's all sorted too .)
Only with a new unit, but so far no more issues.
