Benefits of the Central display are mostly ascetic, it provides more telemetric data due to larger screen with more "digits" and can be angled towards rider independent to position of throttle.

Always check the P-Settings when renewing throttle/display such as P3 Voltage, P6 Wheel Diameter, P7 magnets and P15 Controller cut off voltage.
Notes:
P-Settings apply as specified by Rydology including the option of P18 to bind and unbind cards. This instruction includes ability to bind cards with display off when cards are unusable. Unbinding all cards disables the need to swipe after powering on the scooter. To do this, turn on the display when it show "card" press and hold down + and -, then press start button 17 times (you will be at P18) then hold down - . During this process the display may remain blank. Then shut down scooter and start it again, there should be no card swipe challenge. As shown in video from Adam Welch.
P-Settings adopt those of QS-S4 which is well documented amongst Zero models, as are the error codes. Refer to the inaugural creators of the Zero Brand at Falcon PEV Singapore and Rider Guide or refer to the image below from Hernan Emir Castelan at zero E scooters one pager:
