Our take on the Vizio 55 Class Quantum Series Mini LED Smart TV

The Vizio Quantum Series is the brand's step-up 4K LCD TV, using a mini-LED backlight with 260 local dimming zones and full Dolby Vision and HDR10+ support. That zone count is high for its class, which helps contrast and black levels, but the panel is 60Hz with motion smoothing rather than a true 120Hz native refresh. It suits movie and streaming viewers who want strong HDR and deep blacks without paying OLED money. Gamers should note the low input lag but the 60Hz ceiling, and Vizio's SmartCast platform is less polished than Roku or Google TV.

Questions and answers

Is this a true 120Hz TV?
No. The panel is 60Hz native; the 120 Dynamic Motion Rate figure comes from motion processing, not a 120Hz panel.
Does it support Dolby Vision and HDR10+?
Yes. It handles Dolby Vision, HDR10+, HDR10 and HLG, so it works with most HDR streaming services.
Is it good for gaming?
Input lag is low at under 10ms at 60Hz, but the 60Hz panel means no 120fps gaming. It suits casual console play more than competitive gaming.
How does it compare with OLED?
Mini-LED gives higher brightness and no burn-in risk, while OLED offers better per-pixel contrast and wider viewing angles. This set sits below OLED on black-level precision but above it on brightness.
What sizes does the Quantum Series come in?
The Quantum Series is sold in several screen sizes; check the model number, since features like dimming zones can differ between sizes.
Does it have a 120Hz mode for consoles?
No. There is no 120Hz input mode, so next-gen consoles run at up to 60fps on this set.
Where is the Vizio 55 Class Quantum Series Mini LED Smart TV cheapest?
At Sam's Club, for $278.00, as of our latest check.
