  • Both HDMI ARC and eARC are available, simplifying audio passthrough to external sound systems
  • Compatible with Google Assistant and Amazon Alexa, enabling hands-free voice control
  • 178-degree viewing angles both horizontally and vertically allow for consistent image quality from a wide range of positions
Cons
  • Refresh rate is limited to 60Hz, which may not be suitable for fast-motion content or gaming use cases that benefit from higher rates
  • Dolby Vision and HDR10+ are not supported, limiting compatibility with certain HDR-formatted content
  • No 3.5mm headset jack is available for direct headphone connection
  • The remote control is not rechargeable, requiring disposable batteries
  • Siri and Apple HomeKit are not supported despite AirPlay being present
  • No external memory slot is available for expanding storage or accessing media from memory cards
Who is this for?

This television is well-suited to living room setups where screen size and viewing comfort are priorities, particularly for households where multiple people watch from varying positions — the 178-degree horizontal and vertical viewing angles ensure consistent image quality across a wide seating arrangement. Users who stream HDR content will benefit from the HDR10 and HLG support, and those embedded in a smart home ecosystem built around Google Assistant or Amazon Alexa will find the voice control integration practical. The inclusion of AirPlay and smartphone remote support also makes it a reasonable fit for households that rely on Apple devices for media streaming. The three HDMI 2.1 ports and HDMI eARC support make it accommodating for users who connect multiple source devices alongside a dedicated external sound system.

Who is this NOT for?

Users with a strong interest in high-frame-rate content or console gaming will find the 60Hz refresh rate a limiting factor, as it does not support the smoother motion delivery that higher refresh rate panels offer. Those who specifically seek out Dolby Vision or HDR10+ formatted content will face compatibility gaps, since neither format is supported. The set is also not well-matched to users who want direct headphone connectivity, given the absence of a 3.5mm audio jack, nor to those who need flexible local storage access, as there is no external memory card slot available.
