Best 55-inch smart TVs under $400
Researched by Deal.ai's shopping agent across stores on November 7, 2026. Prices below are today's.
Top pick: VIZIO 55" Mini LED Quantum (VQM55C-10). Mini LED backlighting is what separates a good budget 55-inch from a flat one — deeper blacks, brighter highlights — and this is the best-rated set here by a wide margin, so it's the one to buy if picture quality matters most.
Who the others suit:
- Roku Select Series (2026 QLED) — the best all-rounder if you want Roku's interface and a huge review base behind it.
- TCL S4 / S55LR — the value choice; fine for a bedroom or a second room where you're not chasing contrast.
- Samsung U8000H Crystal UHD — pick it if you're already in the Samsung/Tizen ecosystem or want the most store options.
- onn Mini-LED QLED — cheapest way into Mini LED, but the thinnest review record of the group.
Skip the Hisense "Cinema Series" and the 75-inch LG listings — those aren't 55-inch TVs.
