Sony BRAVIA 3 II 100-Inch 4K TV vs LG QNED84B 100-Inch 4K Smart TV

Both are 100-inch 4K sets, but they use different panel tech. The LG QNED84B is a Mini LED set with Google TV and a 2026 release, so it should give brighter highlights and deeper contrast in a bright room. The Sony BRAVIA 3 II is a standard LED set with a 120 Hz refresh rate, anti-glare coating and Siri support, which suits sports and console gaming. Buy the LG for picture punch and the Sony for motion handling and glare control.

  • Choose the Sony BRAVIA 3 II if you watch a lot of sports or play console games and want 120 Hz motion plus an anti-glare screen in a bright room.
  • Choose the LG QNED84B if you want Mini LED contrast and brightness and prefer the Google TV app and voice ecosystem.

Questions and answers

Which is better for a bright living room?
The Sony has an anti-glare coating, which helps with reflections. The LG's Mini LED backlight pushes brighter highlights. If glare is the main problem, take the Sony; if you want punchy HDR, take the LG.
Which is better for gaming?
The Sony lists a 120 Hz refresh rate, which matters for smooth motion on consoles. The LG's refresh rate is not confirmed in its specs, so the Sony is the safer pick for gaming.
Is the LG worth stepping up to over the Sony?
Yes if picture contrast matters most to you. Mini LED dimming gives deeper blacks and brighter highlights than the Sony's standard LED backlight.
Which has better smart features?
The LG runs Google TV, which has a wide app library, casting and Google Assistant. The Sony offers Siri support, which suits Apple users. Both are capable; pick by ecosystem.
Which lasts longer?
Neither brand publishes a lifespan figure for these models. Both are large LED-based sets with similar panel wear. Build quality is comparable, so longevity depends more on your room and usage than on the model.
Do both support HDR?
The Sony lists HDR support. The LG is a 4K Mini LED set and supports HDR formats through Google TV, though its listed specs do not name them.
