Vizio OS works well, but you don’t even need to use it. When I first started testing Vizio's 65-inch Mini LED Quantum TV, I thought the big story was that Vizio was back and that it had a quantum-dot TV for under $398 - the cheapest on the market. Vizio's been pretty quiet since it was acquired by Walmart in 2024, so putting out a TV with quantum dots, which allow for higher brightness levels and more accurate color, at a budget price seemed like a strong comeback. But that's not the big story
