2019 27" iMac display question

[Crotonmark]

This is crazy so apologies
I have a brand new 27" iMac
What are the best display settings to make the best use of the Vega card and the 5K display?
Is it the default/recommended?
I want to be sure I am not missing out on something
thanks

The best is probably the default setting -- the way it "came out of the box"...
