I did try that, and it does remove the arrows. Actually this is how these parts were originally configured (i.e. with all their pins configured as "passive")
However, when you compile a project containing components that have tons of passive pins, you will end up with a whack-load of warnings telling you a net has a Input Pin without a driving source, as well as other errors related to nets connecting passive pins to other types of pins.
Changing the electrical type of a pin is not an acceptable workaround for this display issue
So, is there a way to hide these symbols withoutchanging the pin's electrical type?
I think you may have to accept this is just the way the software works. Agreed it would be nicer if the graphics was separate from the electrical property so I've submitted this as a suggestion to Altium.
