Overview
Vizio's V555-H11 is a 55-inch 4K UHD LED television built around a 120Hz refresh rate and the SmartCast smart TV platform, aimed at buyers who want a mainstream living room screen with built-in streaming apps.
The V-Series sits in Vizio's value tier, pairing full 4K resolution with a faster-than-basic 120Hz panel for smoother motion in sports and games. SmartCast handles the interface and app library instead of a third-party OS like Google TV or Roku, so account setup and app familiarity depend on prior SmartCast experience. HDMI, USB and Wi-Fi cover the common ways to connect sources and get online.
- 55-inch class 4K UHD LED display
- 120Hz native refresh rate
- SmartCast smart TV platform built in
- HDMI, USB and Wi-Fi connectivity
Who it's for
Fits households replacing an aging TV in a living room or bedroom where 55 inches is the target size and 4K plus decent motion handling matters more than premium contrast. Not the pick for anyone who specifically wants Roku or Google TV as the built-in interface, since SmartCast is Vizio's own system.
Strengths and trade-offs
Drawn from this product's published specifications.
- 55-inch 4K UHD panel
- 120Hz refresh rate for smoother motion
- SmartCast platform with built-in Wi-Fi streaming
- SmartCast is a closed platform, not Roku or Google TV
- No stated HDR or contrast spec
Performance notes
The 120Hz refresh rate gives the panel more frames to work with than a standard 60Hz set, which helps blur reduction during fast camera pans and games that support higher frame rates. LED backlighting and 4K UHD resolution are the two specs doing the heavy lifting for everyday picture quality; HDMI and USB round out wired input options while Wi-Fi handles the smart platform's streaming.
