Which has the better picture, the VIZIO or the Roku?

The VIZIO. Its Mini LED backlight with local dimming produces deeper blacks and brighter highlights than the Roku's direct-lit panel. The VIZIO also supports Dolby Vision, which the Roku does not.

Is the Roku worth $30 more than the VIZIO?

Only if the interface matters most to you. Roku OS is simpler and the rating is higher, but the VIZIO wins on picture, ports and warranty at $248 versus $278 at Walmart as of November 8, 2026.

Which is better for gaming?

The VIZIO, mainly for its four HDMI 2.1 ports. Both are 60Hz panels, so neither gives you 120Hz play. The VIZIO's extra ports make it easier to keep a console, soundbar and streamer connected.

The VIZIO carries a five-year warranty, against the standard one-year coverage on the Roku. That is the clearest measure of how long each maker stands behind the set.

Do both support Dolby Vision?

No. The VIZIO supports Dolby Vision, HDR10+, HDR10 and HLG. The Roku lists HDR10 and HDR10+, so Dolby Vision content plays in a lesser HDR format.

Which is easier for someone who dislikes complicated TVs?

The Roku. Roku OS puts free live TV and apps on the home screen and the voice remote searches across them. SmartCast works fine but takes more getting used to.
