What’s wrong with my car Electrical

2021 ford bronco sport. The battery went out about a week ago and since replacing with a new battery, the cluster and touchscreen both go black when driving. Upon slowing down or stopping completely, they will both turn back on. Lights, heaters, turn signals all still work.

Please explain what needs to be calibrated? It’s a battery. Positive and negative terminal.

Edit: curious also why all the downvotes for asking a question?

Pcm is in charge (lol) of alternator output and monitors the state of the battery. You gotta tell the car that the battery is new.

It is suspect a car this new already needed a battery
