onn 85" 4K Smart TV (85S4V1) vs LG QNED84B Mini LED 4K Smart TV

The LG QNED84B is the better TV for most people who can stretch to it: Mini-LED backlighting, 120Hz with VRR and FreeSync, Dolby Vision and Dolby Atmos, and webOS with the a8 AI processor put it well ahead on picture, motion and gaming. The onn 85S4V1 is a plain 60Hz Direct Lit LED set running VIZIO's platform, and it is the sensible pick if you want a very large screen for casual viewing and don't need HDR formats or gaming features. Owners rate the LG higher (4.7 from 68 ratings versus 4.2 from 935), though the onn has far more reviews behind it. Build and finish favor the LG; the onn is the lighter, simpler set at 65.6 lb with three HDMI ports.

  • Choose the onn 85S4V1 if you want a huge 85-inch 4K screen for everyday watching and streaming and don't care about 120Hz gaming, Dolby Vision or Mini-LED contrast.
  • Choose the LG QNED84B if you watch movies and sport or play console games and want Mini-LED contrast, 120Hz with VRR, Dolby Vision and Dolby Atmos.
