  • Siri and Apple HomeKit are not supported, limiting integration for users within the Apple ecosystem

Who is this for?

This television is a strong fit for users who want a capable setup for both gaming and everyday viewing in one screen. The 144Hz refresh rate paired with G-Sync and FreeSync Premium Pro support makes it well-suited to console and PC gamers who need smooth, tear-free motion, while the full HDR format stack — HDR10, HDR10+, Dolby Vision, and HLG — benefits those who regularly watch HDR content from streaming platforms or physical media. The built-in smart TV platform with Chromecast, AirPlay, and voice control via Google Assistant and Alexa also makes it a practical choice for households looking for flexible, integrated entertainment without relying heavily on external devices. Users who want to connect multiple high-bandwidth sources simultaneously will appreciate having four HDMI 2.1 ports available.

Who is this NOT for?

Users with a strong preference for the Apple ecosystem may find this television limiting, as Siri and Apple HomeKit are not supported. Those who prioritize an ultra-slim wall-mount installation may also be deterred by the 68 mm depth and 18 kg weight, which demand more substantial mounting hardware and effort than thinner, lighter panels. Additionally, users in environments with strict energy efficiency requirements should be aware of the EU energy label F rating, which indicates higher power consumption during normal use. Anyone needing local storage expansion for recording or media playback will also be restricted, as there is no external memory slot available on this model.
