Our take on the LG 48" Class B4 Series OLED 4K UHD Smart webOS TV (2024)

The LG B4 is LG's entry-level 2024 OLED, sold here in a 48-inch size. It pairs an OLED panel with a 120 Hz refresh rate, four HDMI ports and webOS with Google Assistant, Alexa and Siri support. It is the cheapest way into LG's OLED lineup, and the 48-inch is the smallest size in the series. It suits a bedroom, a small living room or a desk setup more than a large, bright room.

Buyers who want OLED on a tighter budget
Pros
  • OLED panel gives per-pixel contrast and near-infinite blacks
  • 120 Hz refresh with HDMI 2.1 features for PS5 and Xbox Series X
  • Four HDMI inputs, useful for a console, soundbar and streamer
  • webOS is fast and carries all major streaming apps
  • Slim panel, 1.8 inches deep, mounts close to the wall
Cons
  • Peak brightness is lower than LG's C4 and G4, so bright rooms wash it out
  • 48-inch is small for a main living-room TV
  • OLED risk of permanent burn-in with static logos and news tickers
  • Built-in speakers are basic; a soundbar is worth budgeting for
  • Only two of the four HDMI ports are full 2.1 bandwidth on this series

What reviewers say

Reviewers treat the B4 as the value pick in LG's OLED range: same deep blacks and gaming features as the step-up C4, with less brightness and a plainer stand. Owners praise picture quality for the price and complain mainly about brightness in sunny rooms and the modest speakers.

Pros
  • Deep blacks and strong contrast for the price
  • Low input lag and smooth 120 Hz gaming
  • Simple webOS interface
  • Good upscaling of 1080p content
Cons
  • Dim compared with C4 and QD-OLED rivals
  • Weak built-in audio
  • Reflective screen in bright rooms
  • Stand feels basic

Questions and answers

Is the LG B4 worth it over the C4?
The B4 costs less and keeps OLED contrast and 120 Hz gaming. The C4 is noticeably brighter and has a better processor, so pick the C4 for a bright living room and the B4 for a darker room or a tighter budget.
Is 48 inches too small for a living room?
For most living rooms, yes. A 48-inch set suits a bedroom, a small apartment or a close seating distance of about 6 to 8 feet. The B4 also comes in 55, 65 and 77 inches if you need more screen.
Does the B4 support 4K 120 Hz for PS5 and Xbox Series X?
Yes. It has HDMI 2.1 inputs with 4K at 120 Hz, variable refresh rate and auto low-latency mode, so consoles run smoothly. Check which ports are full-bandwidth before plugging in a console and a soundbar.
Will the OLED screen burn in?
Burn-in is possible with static content such as news tickers, channel logos or a paused game left on for hours. Vary content, use the screen-off timer and enable the pixel refresh features; normal mixed viewing is low risk.
What is in the box?
The TV, a stand, a remote, a power cable and a quick-start guide. No HDMI cable is included, so buy one for a console or soundbar.
When is the B4 cheapest?
OLED prices fall around Black Friday, Cyber Monday and the weeks before a new model year launches in spring. The 48-inch usually sees the deepest percentage cuts because it is the least popular size.
