Our take on the LG OLED48B4PUA 48" 4K Ultra HDR Smart OLED WebOS TV (2024)

The LG B4 is LG's entry-level OLED for 2024, here in a 48-inch size that suits smaller rooms and desks. It uses a 120 Hz OLED panel with per-pixel contrast, Dolby Vision and HDR10 support, and four HDMI 2.1 ports with VRR and ALLM, so it handles PS5 and Xbox Series X at 4K 120 Hz. The α8 AI Processor 4K and 2.0-channel speakers are a step below LG's C4, which is brighter and has a better processor. Owners praise the deep blacks and gaming features; the main complaints are modest peak brightness in bright rooms and average built-in sound.

Questions and answers

Is the LG B4 good for PS5 and Xbox Series X?

Yes. It has four HDMI 2.1 ports with 4K 120 Hz, VRR and ALLM, plus a response time under 0.1 ms, so consoles run at their full output.

How does the B4 compare with the LG C4?

The C4 is brighter and uses a stronger processor. The B4 keeps the same OLED contrast and gaming features at a lower tier, so it is the better fit for darker rooms.

Does it support Dolby Vision?

Yes, along with HDR10 and HLG. Dolby Vision content from streaming apps plays in that format.

What is in the box?

The TV, its stand, the magic remote and the power cable. A wall mount and HDMI cables are not included.

Does it have a headphone jack?

No. Audio goes out over HDMI eARC, optical or Bluetooth 5.1.

Is 48 inches big enough for a living room?

It suits small to medium rooms and viewing distances of roughly 5 to 7 feet. Larger rooms generally call for 55 inches or more.
