Our take on the VIZIO M55Q6L4 55-Inch Quantum 4K QLED Smart TV

The VIZIO M55Q6L4 is a 55-inch 4K QLED smart TV in Vizio's M-Series Quantum line. It delivers wide color and HDR support at a budget-friendly price, with smart features like streaming apps and voice control. It suits shoppers who want a bright, colorful picture for movies and shows without paying for premium extras like local dimming or high refresh rates. Compared with rivals, it offers quantum dot color and Dolby Vision at an entry-level price, but its 60Hz panel and limited HDR performance are typical trade-offs in this class.
