Our take on the VIZIO 50″ 4K HDR Smart TV with Dolby Vision, WiFi 6, Smart Home – V4K50S-0809

The VIZIO V4K50S-0809 is a 50-inch 4K LCD smart TV built around Dolby Vision Bright+ HDR, with HDR10+, HDR10 and HLG also supported. It stands out on connectivity for its class: WiFi 6, AirPlay 2, Google Cast and Bluetooth headphone listening. Gaming gets Dolby Vision HDR Gaming with Auto Low Latency Mode, though there is no 120Hz panel or HDMI 2.1. Against rivals like the TCL S-class and Hisense A-series, it matches them on HDR formats and beats many on WiFi 6, but its picture is standard LED, not mini-LED, so blacks and brightness are ordinary. It suits budget buyers who want a smart, well-connected bedroom or secondary TV.

Questions and answers

Is Dolby Vision worth it on a TV this size?

Yes if you stream from services that use it, like Netflix and Disney+. Dolby Vision Bright+ adjusts tone mapping for the panel, and the set also handles HDR10+ and HLG for other sources.

Does it support AirPlay and Chromecast?

It supports Apple AirPlay 2 and Google Cast, so you can cast from an iPhone, iPad or Android device and add it to smart home routines.

Is it good for gaming?

It handles Dolby Vision HDR Gaming and Auto Low Latency Mode, which is fine for casual console play. It lacks 120Hz and HDMI 2.1, so serious players should look at a gaming-focused set.
