Our take on the LG 86UR640S9UD 86" Smart LED-LCD TV

The LG 86UR640S9UD is an 86-inch 4K LED-LCD smart TV running webOS, with a 120 Hz panel, HDR support and three HDMI inputs. Its size is the main draw: a screen this large is rare below premium prices, and the 120 Hz refresh helps with sports and games. The panel is a standard-brightness edge-lit LED (about 330 nits, 1200:1 contrast), so it suits dim to moderately lit rooms rather than bright sunlit ones. It comes with an IR remote only, and pricing varies widely by store, so compare sellers before buying.

Questions and answers

Is the LG 86UR640S9UD worth it?
If you want the biggest screen for the money, yes. It delivers 86 inches of 4K at 120 Hz, but picture quality is mid-range: modest brightness and contrast mean it looks best in a dim room.
Is 120 Hz real on this TV?
The panel is listed at 120 Hz, which smooths motion for sports and supports higher frame rates on compatible consoles. Check that your HDMI source and cable support 4K at 120 Hz.
How many HDMI ports does it have?
Three HDMI inputs. That covers a console, a streaming box and a soundbar, but a fourth device needs a switcher.
Does it come with a magic remote?
No. The box includes an IR remote only. A magic remote is sold separately if you want pointer control.
Is it good for a bright room?
Not ideal. At about 330 nits it can look washed out near windows or in direct sunlight. It performs better in controlled lighting.
When is it cheapest?
Large TVs like this usually drop around Black Friday, Super Bowl season and end-of-model clearance. Compare store prices before buying, since discounts vary widely.
