RC Pro Camera View Question

[Cosmo0g]

I just got the RC Pro, and noticed when I'm in camera view, and shooting 4:3 with the Mavic 3, it cuts off a lot of the sides whereas my iPhone 12 max shows that same ratio full screen when using the regular controller. I do get the full screen with 16:9 camera ratio on the RC Pro, and with the video as well. Is there a setting I'm missing to use the 4:3 settings, but still get full screen?
