Our take on the onn 75” Class 4K UHD Roku Smart Television

The onn 75-inch Class 4K UHD Roku Smart TV is a budget large-screen LED set built around the Roku smart platform. It delivers 4K resolution with HDR10 support, a 60 Hz refresh rate, 350 nits of brightness and a 4000:1 contrast ratio, plus three HDMI inputs and Dolby Digital sound from two speakers. It suits shoppers who want the biggest screen for a living room or game room without paying premium-brand money, and it competes on size and Roku's app selection rather than on picture quality. Expect entry-level brightness and contrast compared with midrange and premium 75-inch sets, and plan on a soundbar for serious movie watching.

Questions and answers

Is this TV good for bright rooms?
At 350 nits it is on the dim side. It works best in rooms where you can control glare or watch in the evening.
Does it support HDR?
Yes, it supports HDR10. The panel's brightness limits how much HDR pop you get, so the benefit is modest.
Is 60 Hz enough for gaming?
It is fine for casual console play, but fast-action games will show more motion blur than on 120 Hz sets.
What is in the box?
The TV, its stand feet and hardware, a remote and power cable. Check the listing for the exact remote and stand contents.
Can it be wall mounted?
Yes, it supports wall mounting as well as the included freestanding stand. You need a mount rated for a 75-inch TV.
Does it have a voice assistant?
It works with Google Assistant, and Roku's own voice search is available through the remote.
