Is this TV good for gaming?

It handles casual gaming, but the 60 Hz panel and two HDMI ports make it a weaker pick for fast competitive play than 120 Hz sets.

Does it need a Roku streaming stick?

No. Roku OS is built in, so the streaming apps and interface run on the TV itself.

What HDR formats does it support?

It supports HDR playback for 4K content, which improves contrast and color on compatible shows and movies.

Can I control it with Alexa or Google Assistant?

Yes. It works with Google Assistant, Amazon Alexa and Siri for voice control.

How many devices can I plug in?

There are 2 HDMI ports plus USB, so plan around a soundbar and one console or streamer.

Is it worth it over the cheaper Roku Select Series?

Yes if you want brighter, more colorful QLED picture; the Select Series is a basic LED set with less contrast.

Our take on the Roku Class Plus Series 4K QLED Mini-LED Smart TV 55-inch

The Roku Plus Series is Roku's step-up 4K QLED TV, adding quantum-dot color and mini-LED backlighting over the entry Select Series. It runs the Roku OS built in, so the smart interface, voice search and live TV guide are the same ones Roku streamers are known for. Picture quality is a clear jump over budget LED sets, though at 60 Hz it is not aimed at serious gamers. It suits streamers who want one remote and a bright, colorful picture without paying OLED money.
