Pros & Cons
👍 Pros
- Built-in Roku platform provides access to over 500,000 movies and TV episodes without needing a separate streaming device.
- 4K Ultra HD resolution paired with HDR delivers noticeably sharper and more vibrant images than standard 1080p sets.
- Dual-band Wi-Fi and an Ethernet port give flexible networking options for stable streaming.
- Alexa and Google Assistant compatibility adds hands-free voice control without additional hardware beyond the assistant device.
- Lightweight at 27.1 pounds, making wall mounting and repositioning straightforward.
👎 Cons
- Direct-lit LED backlighting lacks the local dimming zones needed for deep, uniform blacks in dark scenes.
- The 120 Hz figure is a Clear Motion Index (CMI) rating, not a native 120 Hz panel refresh, so actual motion handling is limited.
- With only three HDMI ports, users with multiple consoles, a soundbar, and a streaming stick may run short on inputs.
- No Dolby Vision support limits HDR performance compared to competing sets in this price range.
