onn 55" 4K Roku Smart TV vs Onn 32-inch Roku Smart TV

Buy the 55-inch onn for a main room where size and 4K detail matter. Its 4K panel, three HDMI ports and Roku platform make it the better long-term TV. The 32-inch onn is a small-room or second-screen set: 720p is fine at close viewing distances, and owners praise its bright picture, loud volume and easy setup. Build quality is basic on both, and the 32-inch model's remote draws complaints.

  • Choose the onn 55" 4K Roku TV if you want a big 4K picture for a living room and Roku's app selection.
  • Choose the onn 32" Roku TV if you need a compact, light set for a bedroom, kitchen or dorm and 720p is enough.

What reviewers say

onn 55" 4K Roku Smart TV

Owners generally describe it as a solid value for streaming, with an easy Roku setup and a big 4K picture. Complaints center on brightness, HDR and sound quality rather than the software.

What people mention
  • Picture qualityMixedOwners say the 4K image looks good in darker rooms but washes out in bright light.
  • HDRCriticisedReviewers note HDR content looks flat because peak brightness is limited.
  • SoundCriticisedBuilt-in speakers are described as thin, so many buyers add a soundbar.
  • SetupPraisedRoku setup and app sign-in are reported as quick and straightforward.

Onn 32-inch Roku Smart TV

Owners rate it highly as a cheap second TV. They call the picture bright and clear, the volume louder than bigger-name sets, and setup very easy. The remote is the recurring complaint.

What people mention
  • PicturePraisedBuyers call the picture bright and clear with good screen color for the size.
  • SoundPraisedOwners say the volume is louder than a previous Samsung TV.
  • SetupPraisedReviewers describe setup as very easy.
  • RemoteCriticisedSome reviewers dislike the included remote and prefer the phone app.

Questions and answers

Which is better for a living room?
The 55-inch 4K set. At typical couch distance, 720p on a 32-inch screen looks soft, and the bigger 4K panel shows more detail in movies and games.
Is 720p enough on the 32-inch?
Yes for a bedroom or kitchen where you sit close. At 32 inches, 720p looks acceptable, though text and fine detail are less sharp than 4K.
Which has better sound?
The 32-inch model lists DTS:X with DTS Virtual:X, which owners say is loud and clear. The 55-inch relies on standard TV speakers, so a soundbar helps either way.
Do both run Roku?
The 55-inch is listed with Roku Smart TV. The 32-inch is listed with VIZIO OS and WatchFree+, so check the interface before buying if Roku matters to you.
Which is easier to mount?
The 32-inch is far lighter at 7.9 lb and uses a 200 x 100 mm VESA pattern. The 55-inch needs a sturdier mount at 400 x 200 mm.
Is the 55-inch worth stepping up to?
For a main TV, yes: 4K and the larger screen are the biggest upgrades. For a spare room, the 32-inch covers the basics.
