Is the LG QNED evo better than OLED?

No for contrast and black levels; OLED wins there. The QNED evo is brighter across the whole screen and has no burn-in risk, which suits bright rooms and all-day news or sports viewing.

Does it support 120 Hz gaming?

Yes. The panel is native 120 Hz, and the HDMI ports accept high-frame-rate console and PC signals. Check that your console or GPU and cable support the mode you want.

What is the difference between QNED and NanoCell?

QNED combines Quantum Dot color with NanoCell filtering and a mini-LED backlight. Plain NanoCell sets use a standard edge or direct LED backlight, so they are usually dimmer and have fewer dimming zones.

Which sizes does it come in?

It is sold in 55, 65, 75 and 85 inches. The 65-inch model weighs about 40 lb without its stand, so wall mounting needs a bracket rated for that plus the stand hardware.

Does it work with Alexa and Google Assistant?

Yes. Both assistants are supported through the TV's webOS software, so you can use voice control without adding a separate smart speaker.

Do I need a soundbar?

The built-in speakers are fine for casual viewing but thin on bass. Most owners adding a soundbar or AV receiver report a clear improvement for films and games.
