Our take on the LG 55UM340E0UZ 55-Inch 4K UHD Smart TV

The LG 55UM340E0UZ is a 55-inch 4K LED TV built for commercial and education use, not the living room. It has a 60 Hz panel, a 1200:1 contrast ratio, three HDMI ports, Wi-Fi, Bluetooth and Ethernet, plus management tools like FailOver, LG ConnectedCare DMS and a time scheduler. Its 20 W two-speaker audio and anti-glare coating suit classrooms and meeting rooms more than movie nights. No price was given for this listing, so there is no recent range to compare against.

Questions and answers

Is this TV good for watching movies and sports?
It works, but it is a 60 Hz commercial panel with 1200:1 contrast and 20 W speakers. A consumer LG set at a similar size will usually look better for movies and fast sport.
Does it support 120 Hz or variable refresh rate?
No. The panel is 60 Hz and the specs list no HFR or VRR support, so it is not a gaming-focused display.
What is included in the box?
The listing does not detail box contents. Expect the TV, a stand or wall-mount hardware depending on the SKU, a remote and a power cable; confirm with the seller before ordering.
Can I manage several of these TVs remotely?
Yes. It supports LG ConnectedCare DMS, FailOver and a time scheduler, which are aimed at managing fleets in schools and businesses.
Is it wall-mountable?
It is a flat 55-inch panel about 3 inches deep, so it can be wall-mounted with a compatible VESA bracket. Check the exact VESA pattern for this model before buying a mount.
When is the best time to buy it?
No price history is available for this listing, so there is no reliable cheapest period to point to. Compare quotes from commercial AV resellers rather than consumer retail.
