Key Features
-
Stunning 4K Ultra HD Clarity: Elevate your casual viewing to theater-like immersion. Boasting a native resolution four times sharper than standard Full HD, this panel resolves fine text, intricate facial lines, and background textures with superb macro detail, making all of your favorite modern streaming shows look remarkably lifelike.
-
Direct-Lit LED Backlight Uniformity: Wave goodbye to distracting, uneven dark patches. Unlike edge-lit models that only push illumination from the sides, the Direct-Lit panel layout positions LEDs uniformly across the back of the entire display. This physical orientation generates a consistently bright screen, enhancing overall contrast and enriching color accuracy from edge to edge.
-
High Dynamic Range (HDR10) Realism: Uncover missing elements hidden deep within shadows and bright sunscapes. Natively integrating HDR10 dynamic range formatting, the panel maps brightness and luminance levels frame-by-frame. This delivers deeper black fields, punchier white levels, and an expanded tonal range that brings natural dimension to cinematic content.
-
Delightfully Uncomplicated Roku OS Platform: Take control of your media through the most intuitive smart dashboard on the market. The Roku interface drops all of your physical hardware connections, gaming consoles, and premium streaming apps—like Netflix, Disney+, Prime Video, and Max—onto a single, easily arranged home screen. It also features immediate, out-of-the-box access to The Roku Channel, offering over 500 free live TV channels, local news broadcasts, in-season sports, and exclusive Roku Originals with no monthly subscription required.
-
No-Nonsense Infrared Remote Control: Reclaim simplicity with an interface built for pure function. By discarding hundreds of confusing, unnecessary buttons found on traditional remotes, this streamlined controller keeps only what you need to navigate seamlessly. It offers a highly ergonomic layout that lets you jump between settings and streaming applications by muscle memory alone.
-
Optimized Dolby Audio Soundstage: Enjoy clean, intelligible vocals without constant volume adjustments. Equipped with a dual-channel, downward-firing sound system optimized by Dolby Audio, the TV dynamically refines soundtracks to deliver crisp dialogue and uniform sonic detail, preventing explosive sound effects from completely drowning out characters' conversations.
-
Universal Content Casting with Apple AirPlay: Bridge the gap between your mobile accessories and the big screen. Integrated support for Apple AirPlay and Google Cast lets you mirror personal photos, home videos, music tracks, or mobile browser tabs from your iPhone, iPad, or Android smartphone directly to the 55-inch display with a single tap.
-
Flexible Legacy and Modern Connectivity: Build out your entertainment hub exactly how you want it. With an expansive array of 4 HDMI inputs supporting high-bandwidth eARC, you can route next-generation soundbars, gaming consoles, and streaming sticks simultaneously. It also includes a classic Composite Video input for hooking up retro analog gaming gear, plus a dedicated 3.5mm headphone jack for private late-night listening.
