By: Tamara | Last updated September 4, 2018

  • Very low motion blur
  • Great viewing angles
  • Excellent picture quality
  • Slim, attractive design
  • Voice control works flawlessly
  • Peak brightness not as good as with Samsung QLEDs or the LG C8
  • Not as many available apps as with Android TVs

The B8 OLED from LG is a great TV set, with a fantastic image quality, infinite contrast ratio and a great overall performance. It is the cheaper alternative to the C8, only with a slightly weaker (barely noticeable) processor.

The LG B8 is a great OLED TV and a more affordable alternative to the C8 model. The only notable difference between the two is the processor, with the C8 packing the newer and slightly better Alpha 9 chip, while the B8 only has the Alpha 7. However, performance-wise, this difference is barely noticeable, especially for normal use.

The B8 comes in 2 available sizes: 55-inch and 65-inch and we are going to focus here on the first one.

Here are the main specs of the B8 (55-inch version):

  • Dimensions (W x H x D): 48.3” X 29.6” X 8.7”
  • Weight with stand: 39.2 lbs
  • Resolution: 4K Ultra HD (3,840 X 2,160)
  • HDR format support: Dolby Vision, Advanced HDR by Technicolor, HDR10, HLG
  • Pixel level dimming
  • Infinite contrast
  • A7 intelligent processor
  • Intelligent voice recognition, Google Assistant (compatible with Amazon Alexa, but with the device sold separately)
  • webOS
  • Audio output power: 40W
  • WiFi, WiFi Direct, Bluetooth
  • 4 HDMI inputs
  • 3 USB ports


The design of the B8 is really attractive and the B8 looks almost like the C8, except for the stand, which is narrower on the B8.

The B8 is very slim, with thin black bezels and a thin, metallic stand. The maximum thickness of the B8 is 1.93”. This is a really slim model for an OLED TV.

The connections are located on the back, on the left side: there are 4 HDMI inputs, 3 USB ports (1 on the rear and 2 on the side), 1 composite in, 1 digital audio out, 1 RF input, 1 Ethernet and 1 RS232C (mini jack).

The B8 comes with a large remote control with plenty of functions on it, including dedicated buttons for Netflix and Amazon. It has voice control, which can search and open content for you, tell you how the weather is and more.

Features and performance

The B8 runs webOS 4.0, which is LG’s smart platform. There are some preinstalled apps (Netflix, Amazon Video, YouTube) and you can also download others from the LG store, although you don’t have as many options as with Google Play for instance, which is why Sony prevails in this aspect.

The interface is responsive, works smoothly and you’ve got your Google Assistant, intelligent voice recognition and the LG AI ThinkQ. The TV is also compatible with Amazon Alexa, but you have to buy the Amazon Alexa device separately.

When it comes to picture quality, the B8 doesn’t disappoint. Its image is really sharp, clear and bright, regardless of the content you are watching: HDR or non HDR.

The infinite contrast ratio (pixels can be turned on/off independently of each other) means astonishing blacks, with best results when watching the TV in a dark room. The B8 also handles reflections really well and the viewing angles are great and the image won’t degrade if you are not positioned exactly in front of the TV. The colors of the B8 are rich and vibrant. The brightness of the B8 is really good, especially for an OLED TV, although the peak brightness of the C8 is a bit better.

When it comes to motion handling the B8 also behaves exemplary and can cope with fast-moving content such as sports and gamers will have no problems with it either.

The B8 has a 120Hz native refresh rate.

The sound of the B8 was another pleasant surprise. It can get loud enough and unlike many competitors, it does have a decent bass. It is no match to dedicated speakers, but the overall sound quality is above average.

The LG B8 is a great OLED TV. It is quite expensive, but still a good bargain considering its features and capabilities.

The LG B8 (the 55-inch version) is approximately $2,000. The package also includes the remote control, batteries, a manual, a composite adapter and a 59” power cable. The product comes with a 1-year limited warranty.
