Roku ‎40R2A5R 40"

Manufacturer: Roku

The Roku 40R2A5R 40-inch is a Full HD smart television built around a 1080p LED-backlit LCD panel with Roku's built-in smart TV platform pre-installed, giving users access to streaming apps, a search browser, voice commands, and AirPlay directly out of the box. It works with Google Assistant and Alexa for voice control and supports smartphone remote functionality, making day-to-day navigation flexible across different devices and preferences. A sleep timer, child lock, and a one-year warranty round out the feature set for general household use.

The 39.5-inch screen runs at 1920x1080 pixels with a 60Hz refresh rate, a pixel density of 56 ppi, and an 8-bit color depth capable of rendering 1.67 billion colors. Viewing angles extend to 178 degrees both horizontally and vertically, and the panel includes an anti-reflection coating alongside an ambient light sensor. Connectivity is handled through three HDMI 2.1 ports — one of which supports both ARC and eARC — along with one USB port, Wi-Fi 4, and Miracast support. On the audio side, the TV features stereo speakers, Dolby Audio, digital audio output, and HDMI ARC/eARC, though it does not include a subwoofer or an RJ45 Ethernet port.

Pros
  • Three HDMI 2.1 ports provide ample input options for connecting multiple source devices simultaneously
  • Both HDMI ARC and eARC are supported, making it straightforward to connect a soundbar or AV receiver with full audio return capability
  • The built-in smart TV platform includes AirPlay, a search browser, voice commands, and compatibility with both Google Assistant and Alexa
  • Smartphone remote support adds flexibility for users who prefer not to use a physical remote
  • An anti-reflection coating and ambient light sensor help manage screen visibility across different lighting conditions
  • VESA mount compatibility allows for wall mounting in addition to standard stand use
Cons
  • No HDR support of any kind — HDR10, HDR10+, Dolby Vision, and HLG are all absent, limiting picture quality with HDR content sources
  • The 60Hz refresh rate offers no headroom for smoother motion handling beyond standard broadcast and streaming content
  • Wi-Fi is limited to Wi-Fi 4 (802.11n), with no wired Ethernet port available, which can restrict network reliability
  • There is no external memory slot, limiting local media playback options to the single USB port
  • Siri and Apple HomeKit are not supported despite AirPlay being present, which creates an incomplete Apple ecosystem integration
  • The remote control is not rechargeable, requiring battery replacements over time
Who is this for?

The Roku 40R2A5R is a practical fit for users seeking a straightforward smart TV experience in a secondary room or smaller living space, where the built-in Roku smart platform with AirPlay, Google Assistant, and Alexa support covers everyday streaming and voice control needs without requiring additional devices. The three HDMI 2.1 ports with ARC and eARC support make it a reasonable choice for users who want to connect multiple source devices alongside a soundbar or audio receiver. Its child lock, sleep timer, and smartphone remote support also make it a functional option for shared or family viewing environments where basic content management features are useful.

Who is this NOT for?

Users who prioritize picture quality will find this TV limiting, as it lacks any HDR support — including HDR10, HDR10+, Dolby Vision, and HLG — meaning high dynamic range content from streaming services or disc players will not be rendered as intended. The 60Hz refresh rate and absence of adaptive synchronization make it unsuitable for gaming setups where smoother motion or variable refresh rate support is expected. Additionally, users who rely on a wired network connection for stable streaming will find the lack of an Ethernet port a meaningful drawback, and those embedded in the Apple ecosystem expecting full HomeKit and Siri integration will encounter an incomplete experience given that only AirPlay is supported.

Final Verdict

The Roku 40R2A5R is a functional 1080p smart TV that delivers where it matters most for casual, everyday viewing — its built-in Roku platform with AirPlay, multi-voice assistant support, and three HDMI 2.1 ports with ARC and eARC cover the core needs of a straightforward streaming and connectivity setup without requiring additional hardware. That said, the absence of any HDR support and a 60Hz panel set a clear ceiling on picture quality, and the Wi-Fi 4 only wireless connectivity without a wired Ethernet option may frustrate users in bandwidth-sensitive environments. For a secondary room, family viewing space, or a user whose priorities don't extend beyond standard HD streaming and smart TV convenience, this set covers the essentials reliably — but those chasing a more capable display for gaming or high-dynamic-range content will need to look elsewhere.
