Is the Vizio V Series good for gaming?

Yes for casual console play. Input lag is under 10ms, and it supports VRR and AMD FreeSync at 4K 60fps. It is 60Hz only, so it does not fully serve 120Hz consoles.

Does the Vizio V Series support Dolby Vision?

Yes. It handles Dolby Vision and HDR10+, which is uncommon at this level. Brightness is limited, so the HDR effect is modest compared with pricier sets.

How does it compare with the TCL S Series?

Both are budget 4K sets with similar gaming features. The V Series adds Dolby Vision and HDR10+; TCL's S Series often runs Google TV, which many shoppers find smoother than Vizio Home.

Can I cast to the Vizio V Series?

Yes. Apple AirPlay 2 and Chromecast are built in, so you can cast from iPhones, iPads, Android devices and Chrome browsers.

The TV, a push-to-talk voice remote, a power cable and a stand with screws. A wall mount is not included.

Should I get the 43-inch or 55-inch?
