Roku Pro Series 55-inch 4K QLED Mini-LED (55R8C5, 2025)

The cleanest smart TV platform on a genuinely capable panel: a 120Hz Mini-LED with local dimming that Tom's Guide measured at about 1,500 nits and 9.4 ms of input lag, for well under a thousand dollars. It is the sensible second-room or first-apartment set.

Roku Pro Series 55-inch 4K QLED Mini-LED (55R8C5, 2025)
  • QLED Mini-LED
  • 4K 120Hz
  • 2x HDMI 2.1
  • Dolby Vision IQ / HDR10+

At this price most sets are edge-lit 60Hz panels; the Pro Series brings a Mini-LED backlight with local dimming, a native 120Hz panel with two 4K120 inputs, and Dolby Vision IQ. Tom's Guide measured 1,532 nits and 9.4 ms of lag, and Roku OS stays the simplest, fastest interface for a household that just wants to stream.

Watch out: Roku does not publish the zone count and reviews note blooming around subtitles in dark scenes, so it is not a dark-room movie set.

Pros

  • Roku OS is simple and quick
  • Bright for the price with Dolby Vision IQ
  • 120Hz panel with low input lag

Cons

  • Blooming in dark scenes
  • Only two HDMI 2.1 inputs
  • Narrow VA viewing angle
