Overview
The LG 43UR340C9UD is a 43 inch 4K UHD LED television with a 60Hz refresh rate and LG's webOS smart platform. It connects via Ethernet, HDMI and USB, weighs 19.4 lb, measures 2.2 x 38.1 x 22.2 in, and comes in a navy blue finish.
This set uses standard LED backlighting rather than the self-lit pixels of an OLED panel, a different tradeoff than LG's larger OLED models. The connectivity list here covers Ethernet, HDMI and USB but doesn't mention Wi-Fi or Bluetooth, so anyone planning to stream over a wireless network should confirm that capability before buying. At 43 inches, this is a mid-size set better suited to a bedroom or secondary room than a large living room.
- 43-inch 4K UHD LED panel
- 60Hz refresh rate
- WebOS smart platform
- Navy blue finish
Who it's for
Fits buyers wanting a mid-size 4K smart TV for a bedroom, office or secondary room. Not the pick for viewers chasing the largest screen or OLED-level contrast.
Strengths and trade-offs
Drawn from this product's published specifications.
- 43 inch size fits bedrooms and secondary rooms
- 4K UHD resolution with webOS smart platform
- Ethernet, HDMI and USB connectivity
- Wi-Fi and Bluetooth aren't listed in the spec
- 60Hz refresh rate limits fast motion smoothness
- LED backlighting rather than OLED contrast
Performance notes
LED backlighting drives the panel rather than OLED's self-lit pixels, and the 60Hz refresh rate suits standard viewing more than fast-motion gaming. webOS handles the smart TV app layer on top of the wired connections listed.
