The display on this TV measures 84.5″ and uses a Mini-LED, LED-backlit LCD panel running at a native 4K UHD resolution of 3840×2160 pixels, yielding a pixel density of 52 ppi and a color output of 1.07 billion shades through a 10-bit pipeline. The screen refreshes at 120Hz and supports AMD FreeSync and AMD FreeSync Premium for adaptive synchronization, while HDR coverage spans Dolby Vision, HDR10, and HLG — though HDR10+ is not supported. Viewing angles reach 178° both horizontally and vertically, and the panel includes an anti-reflection coating along with an ambient light sensor that can adjust output based on surrounding light conditions.
The TV offers a well-rounded set of wired and wireless connectivity options, including four HDMI 2.1 ports, two USB ports, and a single RJ45 Ethernet port, with no VGA, DVI, external memory slot, or 3.5mm headset jack present. On the wireless side, it supports Wi-Fi across four generations — Wi-Fi 4, Wi-Fi 5, Wi-Fi 6, and Wi-Fi 6E — alongside Bluetooth 5.3 and Miracast for screen mirroring from compatible devices.
The audio system includes stereo speakers with a built-in subwoofer, and supports a broad range of Dolby formats — namely Dolby Atmos, Dolby Audio, Dolby Digital, and Dolby Digital Plus — though Dolby Virtual and SRS TheaterSound HD are not supported. Digital Out is available for external audio routing, and the TV provides both HDMI ARC and HDMI eARC connections for passing audio to compatible soundbars or receivers.
