Compare LG G6 vs Roku Pro Series (2025)

LG G6

Across movies, sports, games, SDR, and HDR, the G6 delivers a brilliant, cinematic image with deep blacks, rich color, and strong detail. Most criticism centers on firmware-specific flaws rather than the core panel.

23 supporting reviews

Roku Pro Series (2025)

Most owners and experts praise a bright, sharp, vibrant Mini-LED picture that looks excellent with 4K and HDR. A smaller group reports washed-out color, blur, or a less dramatic upgrade than expected.

Built-in sound is fuller and bassier than the G5 and adequate for everyday TV, but it falls well short of the picture quality and usually deserves a soundbar.

11 supporting reviews

Roku Pro Series (2025)

Built-in sound is one of the TV’s biggest advantages, frequently described as soundbar-like and unusually full for a flat-screen. A minority still prefers an external system.
