Last refreshed Aug 4, 2026 · Based on the Amazon listing and published specifications, not hands-on testing.
A well-connected NanoCell set for a bright room where streaming apps, gaming consoles and a soundbar all need a home. The stand is deep and the panel is not the brightest LED LG makes, so a very dark theater room deserves a different screen.

Overview
A gamer or streamer gets a NanoCell panel with the a7 Gen 3 Processor 4K handling AI Picture, AI Sound and 4K upscaling. Nano Color and Nano Accuracy keep skin tones and color consistent across wide seating angles, while Local Dimming balances the direct LED backlight behind the picture. The Magic Remote pairs over Bluetooth for voice and motion control through webOS, and the HDMI inputs plus the USB ports cover consoles, streaming sticks and drives.
NanoCell color and a direct LED backlight with Local Dimming give this screen its character, and the a7 Gen 3 Processor 4K runs upscaling, AI Picture and AI Sound without input from the viewer. The HDMI inputs and USB ports mean consoles, a soundbar and streaming gear can stay plugged in at once. The limitation is light output: Local Dimming improves contrast, but this is an LED panel rather than a brighter backlight technology, so a room with heavy daylight or a projector-style dark cave may want something else.
Who it's for
A household that juggles streaming apps, a game console and a soundbar will find the port count and webOS platform easy to live with, and the Magic Remote covers voice and motion control. Dolby Vision IQ adjusts the picture to ambient light, which suits a room that changes from day to night. Buyers who want the deepest blacks an LED can reach, or who plan a very bright sunlit wall, should look at a different panel type.
Pros and cons
- Nano Color at wide viewing angles
- Local Dimming for deeper black
- 120 hertz panel with TruMotion 240
- Four HDMI and three USB ports
- No stand width or depth listed
- Panel brightness not specified
- No HDMI 2.1 port stated
- Warranty covers parts and labor only
Performance notes
Local Dimming adjusts the direct LED backlight in zones behind the picture, which lifts contrast in dark scenes without washing out bright ones. Nano Color and Nano Accuracy work at the panel level to hold color steady as viewers move off center, and the a7 Gen 3 Processor 4K handles upscaling, AI Picture and AI Sound on its own. Motion clarity comes from the native refresh rate with TruMotion processing, so fast camera pans and game movement read more cleanly than on a lower refresh panel.

How do I control the LG 49NANO85UNA?
Control runs through the Magic Remote over Bluetooth with voice and motion control, and the set also lists Alexa and Google Assistant as controller types. The remote needs two AA batteries, and the webOS platform handles apps and settings on screen.
Can the LG 49NANO85UNA be used as a computer monitor?
