onn 85" 4K Smart TV (85S4V1) vs VIZIO Quantum 4K QLED VQD85R-10

The VIZIO VQD85R-10 is the better TV. It adds a QLED layer with full-array local dimming, Dolby Vision and HDR10+, and Wi-Fi 6, so it handles bright rooms, dark scenes and HDR streaming better than the onn 85S4V1. The onn runs the same VIZIO OS and gives you the same 85-inch 4K picture, but with a plain direct-lit panel and 60Hz. Owners rate the VIZIO higher, and the step up is worth it if you watch a lot of HDR movies or sport.

  • Choose the onn 85S4V1 if you want the largest screen for the least outlay and mostly watch cable, YouTube and casual streaming in a dim room.
  • Choose the VIZIO VQD85R-10 if picture quality matters to you and you want Dolby Vision, full-array dimming and Wi-Fi 6 on a big screen.

What reviewers say

  • 4.2 / 5935 ratings

Rated 4.2 out of 5 from 935 ratings, buyers mostly treat it as a lot of screen for the money. Complaints tend to center on picture quality at the edges and sound rather than the size.

What people mention
  • ValuePraisedOwners say the size-to-price ratio is the main reason to buy it.
  • Picture qualityMixedFine for everyday viewing, but black levels and off-angle viewing draw complaints.
  • SoundCriticisedBuilt-in speakers are described as thin, pushing many buyers to add a soundbar.

Questions and answers

Which is better for watching movies in a dark room?
The VIZIO VQD85R-10. Its full-array local dimming and Dolby Vision produce deeper blacks and better contrast, while the onn's direct-lit panel washes out dark scenes.
Do both run the same apps?
Yes. Both use VIZIO OS, so Netflix, YouTube, Disney+ and the free live TV channels are the same. The VIZIO adds Wi-Fi 6, which streams 4K more reliably on a busy network.
Which is better for gaming?
Neither is a gaming TV. Both are 60Hz with no VRR or ALLM. The VIZIO's better HDR makes games look richer, but fast shooters will feel the same on both.
Is the VIZIO worth stepping up to over the onn?
For most people, yes. You get QLED color, local dimming and full HDR format support on the same 85-inch size. Step down to the onn only if you mainly watch SDR cable and casual streaming.
Which lasts longer?
Both are LED TVs with similar panel lifespans, and neither brand publishes a rated hours figure. The VIZIO's higher owner rating suggests fewer complaints, but treat lifespan as comparable.
Can I wall-mount either one?
Yes. The VIZIO lists a 500mm x 300mm VESA pattern. The onn weighs about 65.6 lb, so use a mount rated for that weight and check its VESA pattern before buying.
