Our take on the 70" Onn 100012588 4K Ultra HDR Smart LED Roku TV
The Onn 70-inch 4K Roku TV is a budget large-screen LED set with the Roku smart platform built in. It covers the basics for a big living room or game room: 4K resolution, HDR playback, and the Roku home screen with its full app catalog and voice search through the remote. Picture quality is entry-level for the size, so it suits shoppers who want the most screen for the least money rather than deep blacks or wide viewing angles. Against rivals from TCL and Hisense, it gives up some brightness and contrast but keeps the same Roku interface many people already know.
- Large 70-inch screen for a budget set

Questions and answers
- Is this TV good for a bright room?
- It is not very bright, so glare from big windows can wash out the picture. It does better in a room you can dim.
- Does it support HDR?
- Yes, it accepts HDR content, but the panel's limited brightness means the effect is subtle rather than dramatic.
- What smart platform does it use?
- Roku is built in, with the full app catalog, voice search through the remote, and casting from phones.
- How does it compare with a TCL or Hisense 4K TV?
- Those rivals usually offer better contrast and brightness at similar sizes. This set competes on screen size and the Roku interface.
- Do I need a soundbar?
- Most owners find the built-in speakers thin, so a soundbar is a common add-on for movies.
- Can I wall-mount it?
- Yes, it has standard VESA mounting points, though a 70-inch set needs a sturdy mount and two people to hang.
