Does the Roku Streaming Stick 4K work with any TV?

Sure does — Roku Streaming Stick 4K works with any TV that has an HDMI port. For 4K, Dolby Vision, and HDR10+ playback, you’ll need a compatible 4K/HDR TV and compatible content. Otherwise, it streams at your TV’s supported resolution (e.g., up to 1080p on HD TVs).

Key details:

  • 4K/Dolby Vision/HDR10+ output requires a compatible TV and content; otherwise output matches TV capability (e.g., HD).

Roku Streaming Stick 4K is a great alternative to cable or satellite.

Key details:

  • Free & paid options: Combine free TV (including 500+ live channels on The Roku Channel) with the subscriptions you prefer; add a cable replacement for local channels and sports if needed.
  • No extra fees: Avoid monthly equipment rentals and long‑term contracts common with cable bundles.
  • What you need: High‑speed internet (25 Mbps recommended for 4K).
  • Compatibility: Works with any TV that has HDMI; 4K/Dolby Vision/HDR10+ playback requires compatible TV and content.
