Pros

The 144Hz refresh rate combined with AMD FreeSync Premium support makes for smooth motion handling across fast-moving content
Four HDMI 2.1 ports provide ample connections for multiple high-bandwidth devices simultaneously
Wi-Fi 6E support ensures fast and reliable wireless connectivity on less congested network bands
The built-in subwoofer adds low-frequency output without requiring an external speaker setup
Both HDMI ARC and eARC outputs offer flexible options for connecting external audio systems
Broad Dolby audio support including Dolby Atmos, Dolby Digital Plus, and Dolby Audio covers a wide range of content formats

Cons

At 68,084 g, the substantial weight makes installation and repositioning physically demanding
Dolby Vision and HDR10+ are both unsupported, limiting compatibility with certain HDR content libraries
Only two USB ports are available on a display of this size, which may feel restrictive for simultaneous device connections
The remote control is not rechargeable, requiring regular battery replacements
There is no 3.5 mm headset jack, ruling out direct wired headphone connection
The warranty period covers only one year

Who is this for?

This television is well suited to large living spaces or dedicated home theater rooms where a 100.3″ screen can be appreciated at a comfortable viewing distance. The 144Hz refresh rate and AMD FreeSync Premium support make it a practical choice for console and PC gaming on a big screen, while the four HDMI 2.1 ports accommodate multiple devices without the need for a switch. Users who want a fully integrated smart home setup will also benefit from the built-in Google Assistant and Amazon Alexa compatibility, AirPlay support, and voice command functionality.

Who is this NOT for?

This television is not a practical fit for smaller rooms or compact living spaces, where a 100.3″ panel measuring over 2,230 mm wide would overwhelm the environment and make comfortable viewing distances difficult to achieve. Its weight of over 68 kg also makes it unsuitable for users who require easy repositioning or plan to wall-mount the set without professional installation assistance. Those who rely heavily on Dolby Vision or HDR10+ content from streaming services will find the lack of support for both formats a meaningful limitation, and users looking for a headphone output for private listening will be disappointed by the absence of a 3.5 mm audio jack.

Final Verdict

The LG 100QNED85AU is a large-format television built around a clear set of priorities: immersive scale, smooth motion, and a well-rounded feature set for both entertainment and smart home integration. Its 144Hz refresh rate with AMD FreeSync Premium and four HDMI 2.1 ports give it genuine practical appeal for gaming and multi-device setups, while the Dolby Atmos support and built-in subwoofer round out the audio side without requiring immediate external investment. The absence of Dolby Vision and HDR10+ is a real limitation for HDR-focused viewers, and the sheer physical demands of a 100″ panel mean it is only a realistic choice for spaces and installations that can properly accommodate it. For those who can meet those requirements, it represents a comprehensive and technically capable option at this screen size.
