Our take on the LG B4 4K OLED Smart TV

The LG B4 is LG's entry-level OLED, sitting below the C4. It keeps the core OLED strengths: per-pixel contrast, near-instant response and wide viewing angles, with four HDMI 2.1 ports at 4K 120Hz, Dolby Vision and VRR for consoles. It steps down to the α8 processor, a 2.0-channel 20W speaker system and Wi-Fi 5 instead of Wi-Fi 6E. Reviewers rate it as one of the best-value OLEDs for film and gaming, though the C4 is brighter and has better processing.

Best forMovie watchers who want true blacks in a dark roomConsole gamers needing four 4K 120Hz HDMI portsBuyers stepping up from LED who want OLED contrastSmaller rooms and bedrooms in 48 and 55 inches
Pros
  • Per-pixel OLED contrast with perfect blacks
  • Four HDMI 2.1 ports with 4K 120Hz, VRR and ALLM
  • Dolby Vision, HDR10 and HLG support
  • Low input lag and fast panel response for gaming
  • Wide viewing angles; webOS with all major apps
Cons
  • Lower peak brightness than the C4 and G4
  • α8 processor handles upscaling and motion less cleanly than the α9
  • 20W 2.0 speakers are thin; a soundbar is worth adding
  • Wi-Fi 5 only, no Wi-Fi 6E
  • No MLA panel, so bright-room performance is average

Questions and answers

Is the LG B4 worth it over the C4?
The B4 covers the basics for less: same OLED panel strengths and four HDMI 2.1 ports. The C4 is brighter and has the better α9 processor, so pick it if you watch in a bright room or care about upscaling.
Is the B4 good for PS5 and Xbox Series X?
Yes. All four HDMI ports support 4K at 120Hz with VRR and ALLM, and input lag is low. It also supports Dolby Vision gaming.
What sizes does the B4 come in?
It is sold in 48, 55, 65, 77 and 83 inches. The 48-inch is the smallest and suits bedrooms and small rooms.
Does the B4 support Dolby Vision and Dolby Atmos?
It supports Dolby Vision, HDR10 and HLG for picture. It decodes Dolby Atmos but the built-in 2.0 speakers cannot produce height effects.
Do I need a soundbar with the B4?
Most owners add one. The 20W 2.0 speakers are clear but lack bass and scale, so a soundbar or AV receiver improves films noticeably.
Does it have Wi-Fi 6?
No. The B4 uses Wi-Fi 5, while step-up LG models add Wi-Fi 6E. Streaming 4K still works fine on a solid Wi-Fi 5 connection.
Where is the LG B4 4K OLED Smart TV cheapest?
At JourneyEd, for $930.95, as of our latest check.
Where can I buy the LG B4 4K OLED Smart TV?
