Which has the better picture?

The VIZIO. Mini LED local dimming and QLED color give it much deeper blacks and higher brightness than the Roku's direct-lit LED panel. The Roku cannot show Dolby Vision.

Which is easier to use?

The Roku. Roku TV is one of the simplest interfaces, and it adds a lost remote finder and headphone mode. VIZIO's SmartCast takes more getting used to.

Is the VIZIO worth it over the Roku?

It costs less: $248.00 at Walmart versus $266.94 at Best Buy as of November 8, 2026. You get the better picture for less money, so it is worth it unless simplicity matters most.

Which is better for gaming?

The VIZIO, mainly for connectivity: four HDMI 2.1 ports versus three. Both are 60Hz panels, so neither suits high-frame-rate console gaming.

The VIZIO carries a five-year warranty; Roku's standard TV warranty is one year. Neither brand publishes a rated panel lifespan, so the warranty is the clearest difference.

Do both support HDR10+?

Yes. Both handle HDR10+ and HLG. Only the VIZIO adds Dolby Vision and plain HDR10.
