Best 75-inch 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 75" Class Crystal UHD U7900F. At this size and price, Samsung's Crystal Processor 4K and its upscaling do the most for everyday streaming, and the Tizen smart platform is the smoothest to live with. Buy it from a mainstream retailer rather than a marketplace listing.
Who the others suit:
- Philips 75" QLED Roku — the only QLED here, so the best contrast and colour for a bright room; Roku is the easiest interface for guests and older users.
- Insignia 75" Fire TV — best if you already live in Alexa and Prime Video.
- Philips 75" Google TV — for Android/Chromecast households.
- onn 75" by VIZIO — the budget fallback when the others sell out.
At this price expect 60Hz panels and modest HDR; a soundbar is worth budgeting for.
