Our take on the LG 55-Inch 4K Ultra HD Smart OLED TV (2018 Model)
The LG 55-inch 4K OLED (2018) is a premium smart TV built on an OLED panel, so each pixel lights itself and can switch fully off. That gives near-perfect blacks, wide viewing angles and very fast pixel response, which suits dark-room movies, sports and gaming. Its rivals are mostly LED LCD sets at the same size: those go brighter in a sunlit room, but none match OLED contrast. Owners praise the picture and design and note the risk of image retention and lower peak brightness.
- Per-pixel OLED panel with true blacks and no backlight bloom
- Wide viewing angles with little color shift
- Very fast pixel response for motion and games
- Slim panel and thin bezels
- webOS smart platform with a simple pointer remote

Questions and answers
- Is OLED worth it over an LED TV?
- OLED gives true blacks and wide viewing angles that LED sets cannot match. LED sets go brighter, so pick OLED for dark rooms and LED for very bright ones.
- Can the screen burn in?
- Yes, static logos, tickers and game HUDs can leave permanent marks over long use. Vary content and use the screen-off and pixel-refresh features.
- Is it good for gaming?
- The fast pixel response keeps motion clear and input lag is low for its time. It lacks the high refresh rates and HDMI 2.1 features of newer sets.
- Does it support HDR?
- Yes, it supports HDR10 and Dolby Vision. Peak brightness is limited, so HDR highlights are less punchy than on bright LED rivals.
- What is in the box?
- The TV, its stand, the magic remote and power cable. A wall mount and HDMI cables are not included.
- How does it compare with the 2019 OLED models?
- Newer models add HDMI 2.1, higher refresh rates and better processing. This 2018 set still delivers the core OLED contrast at a lower tier.
