Vizio firmware 4.25.11 is a mid-cycle system software update for Vizio’s SmartCast 4.0 and 5.0 platforms. Unlike major annual overhauls (e.g., the jump from SmartCast 3.0 to 4.0), version 4.25.11 is a maintenance and feature refinement release.
It primarily focuses on:
The firmware was first pushed to beta testers in late July 2024, with a public wide rollout starting in September 2024.
