Is the LG 74B QNED a good TV for a bright living room?

Yes. Its Mini LED backlight pushes high brightness, so daytime viewing and reflections are handled better than on standard LED sets. Dark-room black levels are good but not OLED-level.

How does the 74B compare with LG's QNED90 or QNED99?

The 74B sits below both. The higher tiers add more local dimming zones and better anti-glare and viewing-angle treatment, which shows up mainly in dark scenes and off-axis seats.

Does this TV support Dolby Vision?

No. It handles HDR10, so Dolby Vision titles from streaming services play in standard HDR instead. Check whether your main apps rely on Dolby Vision before buying.

What is included in the box?

You get the TV, the stand legs, the Magic Remote, a power cable and the setup guide. A wall mount and any HDMI cables are sold separately.

Is 85 inches too big for an average room?

At a typical 8 to 10 foot couch distance an 85-inch set fills the view and suits movies and sports. In a smaller room it can feel overwhelming, and the panel is heavy enough to need two people to set up.

Does it work with soundbars and game consoles?

Yes. It has multiple HDMI inputs for a console and soundbar, and it supports HDMI eARC for passing audio to a soundbar. Check the input count on the back panel if you have several devices.
