Overview

The TCL 65S425 brings 65 inches of 4K Ultra HD resolution to your living room with the simplicity and content depth of the Roku smart TV platform. Its 3840 x 2160 panel paired with HDR support renders movies, sports, and gaming content with improved clarity, color range, and contrast over standard 1080p displays. The direct-lit LED backlighting provides uniform brightness across the large screen, and TCL's upscaling engine works to sharpen lower-resolution sources so that cable TV, older Blu-rays, and SD streaming content still look presentable on the UHD panel.

The Roku operating system is the centerpiece of the smart TV experience, offering a clean and responsive interface with access to thousands of streaming channels including major platforms and niche services alike. Voice control through Amazon Alexa or Google Assistant adds convenience for searching titles, launching apps, and controlling playback. Connectivity includes three HDMI 2.0 ports with HDCP 2.2 support (one with ARC for soundbar passthrough), a USB port for local media playback, composite AV inputs for legacy devices, optical audio output, a headphone jack, and both dual-band Wi-Fi and a hardwired Ethernet port. At 57.3 inches wide and 3.1 inches deep without the stand, the 65S425 is a manageable size for wall mounting on its 200mm x 200mm VESA pattern or placement on a sufficiently wide media console.

Pros & Cons

👍 Pros

  • Large 65-inch 4K UHD screen delivers an immersive viewing experience for movies and sports
  • Built-in Roku platform eliminates the need for an external streaming device with access to over 500,000 titles
  • Three HDMI inputs and composite AV input provide flexibility for connecting multiple source devices
  • Dual-band Wi-Fi and Ethernet port support both wireless convenience and wired reliability
  • Compatible with Alexa and Google Assistant for hands-free voice control

👎 Cons

  • Direct-lit LED panel without local dimming produces less contrast and shallower blacks than VA or OLED alternatives
  • Native 60Hz panel relies on 120 Hz CMI motion interpolation, which is not equivalent to a true 120Hz refresh rate
  • No Dolby Vision or advanced HDR format support limits performance with premium streaming content
  • Stand requires 51.3 inches of separation, demanding a wide TV console or entertainment center
  • Built-in audio lacks bass depth and dynamic range, making an external sound system highly recommended at this screen size
