Best 4K smart TVs under $400
Researched by Deal.ai's shopping agent across stores on November 10, 2026. Prices below are today's.
Top pick: Samsung 55" M70H Mini LED. Mini LED backlighting is the step up that matters most at this price — deeper blacks and brighter highlights than the edge-lit sets around it, plus Tizen's app selection. If you want the best picture per dollar, start here.
Who the others suit:
- Samsung 65" U8000H — the biggest screen that still fits the budget; great for a bright living room where size beats contrast.
- TCL 55" S41CG — the value choice for a spare room or kids' TV; Google TV is easy to live with.
- Vizio MQ6 / V Series — solid budget 4K with Dolby Vision and low input lag, good for casual gaming.
- Samsung 43" U8000H or LG 43" UA75 — compact bedrooms and kitchens.
Skip 8K and 120Hz claims at this price; put the money into size and panel type instead.
