Our take on the LG B4 Series 48" 4K Ultra HDR Smart OLED WebOS TV (2024)
The LG B4 is LG's entry-level 2024 OLED, a 48-inch 4K set with a 120Hz panel, four HDMI 2.1 ports and the webOS smart platform. It uses the same self-lit OLED panel technology as LG's pricier C4, so it delivers deep blacks and wide viewing angles, but it has a less bright panel and a slower processor than the C4. It suits movie watchers and console gamers who want true OLED contrast without stepping up to the C series.
- Self-lit OLED panel gives near-perfect blacks and strong contrast
- Four HDMI 2.1 ports support 4K at 120Hz on consoles
- Wide viewing angles keep the picture consistent off-axis
- webOS is fast to navigate with all major streaming apps
- 120Hz refresh with VRR and ALLM for gaming

Questions and answers
- How does the LG B4 compare with the LG C4?
- Both use OLED panels, but the C4 is brighter and has a faster processor for better upscaling. The B4 keeps the same 120Hz panel and HDMI 2.1 gaming features for less.
- Is the LG B4 good for PS5 and Xbox Series X?
- Yes. It supports 4K at 120Hz, VRR and ALLM over HDMI 2.1, so consoles can run at high frame rates with low lag.
- Is 48 inches big enough for a living room?
- It suits smaller living rooms, bedrooms and close seating. For a large room with seats far from the screen, a bigger size in the same series is the better fit.
- Does the LG B4 support Dolby Vision and Dolby Atmos?
- Yes, it supports Dolby Vision HDR and Dolby Atmos passthrough, so compatible soundbars and receivers can handle Atmos audio.
- What is in the box?
- The TV, its stand, a remote and the power cable. A wall mount and HDMI cables are not included.
- Is the LG B4 bright enough for a sunny room?
- It is dimmer than the C4 and most LCD rivals, so it performs best in dim or controlled lighting. In a bright room, expect more glare and less HDR punch.
