Recall on 21 Bronco replaced the camera (and updated software). Don't think it was specific to size of screen. Mine was swapped out and have no issues since.

Description
Replace rear view camera
Safety Risk
The loss of the rear camera image...
Was originally considering replacing the OEM with another brand when their time was up ... but 60K miles later and have plenty of tread left. The Goodyears served me well and I'm sticking with them when it's time to replace.
Following as same thing just started happening to me a couple of weeks ago. Works intermittently. Unfortunately (?) worked when brought in to service to have checked. Frustrating knowing i'll have to schedule another service appointment not knowing if it will or will not be working on that hour...
