f your entire Xbox screen is magnified, hold the Xbox button and press the View button to toggle it off
In game was the only way i know :unsure:
To zoom in/out on Diablo II: Resurrected using an Xbox controller, you can toggle the camera view by pressing LT + D-pad Up to zoom in, and LT + D-pad Down to zoom out
Says google.
not this or this sadly, its all the way zoomed out from the xbox viewing but still zoomed in, wondering if its a resolution thing on my tv but havent been able to fix that, going to reinstall the game if still have the zoom in then ill assume its my tv
