Product Snapshot

Overview

The LG B3 OLED was released in 2023, and it’s considered one of the best TVs out there, available in sizes 55-77 inches. It’s a mid-tier LG model that features LG’s α7 AI Processor Gen6 to power audio and visuals. The OLED technology also creates deeper backs, as the technology individually lights each pixel.

The TV has an Inf:1 contrast ratio, 99.62% DCI P3 color gamut, 70–degree viewing angles, supports up to a 120Hz refresh rate, and has four HDMI inputs (two of which are 2.1). It also offers VRR Dolby Vision and has gaming features, like LG’s Game Optimizer. The TV runs on LG’s webOS platform. See how it compares to the best OLED TVs today.

Consensus

our Verdict

The LG B3 OLED TV excels for high-quality HDR viewing experiences, such as with 4k or 8k content. Its OLED display means blacks are near-perfect, and it’s capable of displaying truly accurate images without haloing or blooming, given its Inf:1 contrast ratio, which sits at the top of the category. However, in bright rooms, the image quality drops off, as the TV’s peak brightness, at 390 nits, is in the bottom third of the category

As for motion handling, the TV experiences little to no blurriness or tearing during fast-paced scenes, as its pixel response time comes in at 3.1 ms, which is in the top 10% of the category. Gamers also will enjoy the quick command inputs, as the TV has an input lag of 11.7 ms, which is great for an OLED TV. It also quickly refreshes frames with its 120Hz refresh rate. Finally, the TV is welcoming to larger groups, as the 70-degree viewing angles mean those sitting at off-center angles won’t experience diminished brightness.

Reason to Buy

  • Excellent picture quality
    • The LG B3 OLED excels in dark room viewing and provides accurate colors. The TV covers a broad range of vibrant colors, as its DCI P3 color gamut measures 99.62%, which is in the top 10% of the OLED TV category.

  • Great Contrast
    • It provides incredibly deep, near-perfect blacks and an Inf:1 contrast ratio, which leads to virtually no blooming or haloing, and it ranks in the top 10% of OLED TVs. The contrast also makes it great for handling reflections.

  • High-performance motion handling
    • The LG B3 provides near-instant command inputs, which is great for high-intensity gaming, given the input lag is 11.7 ms.

    • Fast-paced scenes come through clear and without blur, as the response time clocks in at 3.1 ms, which is in the top 10% of the OLED category.

  • Fast refresh rate
    • Viewers experience almost no image tearing during fast-paced scenes, given the TV has a 120 Hz refresh rate and VRR support to reduce tearing effects further.

  • Wide Viewing Angles
    • Viewers can watch from off-center angles because the TV delivers 70-degree viewing angles before losing brightness.

    • Color washout angles are also impressive, coming in at 64 degrees before the colors begin losing vibrance.

Reason to Avoid

  • Below Average Brightness
    • The TV struggles to produce great images in rooms with ambient light, as the peak brightness (SDR) tests measure out to 390 nits. Its HDR peak brightness isn’t impressive, which is 617 nits. Both rank at the bottom third of the category.

  • Aggressive ABL
    • ABL can be hyperactive in bright rooms and bright environments, which can get distracting and degrade cinematic quality

  • Mediocre speaker sound quality
    • The built-in speakers experience noticeable levels of distortion when turned up to higher volume, especially during sequences with strong bass.

The LG C3 OLED TV is positioned as a mid-to-high range model, and the LG B3 is a true mid-tier option. For example, the C3 is equipped with the α9 AI Processor Gen6, while the B3 has the less powerful α7 AI Processor Gen6. The C3 also has much higher brightness than the B3, offering 617 nits, while the B3 has 390 nits. Another key advantage of the C3 is the four 21 HDMI inputs that handle up to 120Hz refresh rates. The B3 has four HDMI inputs, but only 2 are 2.1 bandwidth.

LG B3 OLED outdoes the Sony A95L OLED TV in terms of brightness.The B3 delivers a peak brightness of 390 nits, compared to the Sony’s 368 nit peak brightness. However, the Sony excels in image processing and does better at low-quality content smoothing. However, the B3 has a lower input lag of 11.7 ms compared to Sony’s 14.4 ms lag. The Sony also has more robust connectivity, offering a USB 3.0 input, whereas the LG has no USB inputs. For a look at a great 4k option, check out our Hisense U8K TV review.

The LG G3 is the brand’s highest-tier OLED unit, whereas the B3 is middle-of-the-pack. With Micro Lens Array (MLA) technology, the G3 offers much better brightness, 527 nits compared to the B3’s 390 nits. It also has superior technology, offering α9 AI Processor Gen6, neither of which the B3 has. Another large advantage comes by way of inputs; the G3 has four 2.1 HDMI bandwidth inputs, and the B3 only has two 2.1 HDMU inputs. Additionally, the G3 has 3 USB slots, which the B3 completely lacks. However, the B3 has a better input lag—11.7 ms—compared to the G3’s 11.8 ms lag
